For and about the United Kingdom Atomic Energy Authority COMPASS starts journey on a high COMPASS – one of the key fusion experiments at UKAEA’s Culham Science Centre in the 1990s – started its epic journey east on a high. On 17 September, COMPASS was successfully lifted from one of the main experimental halls by a 500-tonne crane. By mid-October, it will have completed its journey to the Institute of Plasma Physics in Prague. At the Institute, it will be reincarnated as a new experiment, the centrepiece of the expanding Czech fusion research programme. UKAEA Project Manager Andy Cullen said, “At Culham, we are working with partners from around the world to bring fusion energy to fruition. This project is a good example of such partnerships. COMPASS will offer a valuable training tool for young Czech scientists and engineers as they look to build up their contribution to international fusion research.” The lift was a spectacular sight. The 20-tonne machine was hoisted through the roof of the hall, 30 metres in the air, before being prepared for its 700-mile trek by road and sea to Prague. COMPASS was an integral part of fusion research at Culham in Oxfordshire and performed many important experiments in support of the design of the international ITER experiment now being built in France. As part of a strongly co-ordinated European research programme, scientists at Culham are delighted to see new life breathed into COMPASS in the Czech Republic. Building complete : 9 Shutting down and cleaning up the fast reactor experiment at Dounreay forms a large part of the economy in the north Highlands. It is worth an estimated £80 million a year to Caithness and north Sutherland and accounts for one in every five jobs locally. But shutting down the site means that almost all these 2,000 or so jobs will have disappeared by the time the clean-up is finished in 2032. The workforce is expected to reduce by a quarter within a few years and most jobs are expected to have gone in little more than a decade from now. A new programme launched in September aims to help workers decide what they want to do when their existing skills are no longer required and give them the resources they need to do it. Plan-It is a voluntary initiative based on a pioneering self-help scheme developed by Liverpool University and funded by local development agency HIE Caithness and Sutherland. Trade unions have backed the scheme and its learning reps are playing a key Continued on page 2 role in the delivery. Dounreay Our nuclear heritage : 4 Ten new faces : 6 Energy Minister launches career plan Culham Issue : 93 October 2007 Harwell Windscale Testing event : 12 Plus all the news from your site… Winfrith 2 UKAEATODAY October 2007 Cadarache visit n Bonus news n Shadow working n Shared services Energy Minister launches career Continued from page 1 plan Seeing ITER Through a series of thought-provoking sessions, Plan-It aims to get workers thinking about where they want to be in 3-5 years’ time and to begin planning for that now. They will be helped to set personal goals, such as retraining for a different job, selfemployment or retirement, with financial support and practical advice available to make it happen. The first 64 places on the initiative have been snapped up and there is now a waiting list for the next batch of sessions. Energy Minister Malcolm Wicks met some of the first group when he visited Dounreay before attending a conference in Thurso about economic regeneration. “We all want to see this site decommissioned in a way that takes account of the social and economic consequences of closure,” he said. “That is why I warmly welcome this initiative by UKAEA, on behalf of the Nuclear Decommissioning Authority, to help workers plan now for the day when their current job comes to an end.” Dounreay Director Simon Middlemas said, “We have a duty to close down this site in a way that gives our workforce and local community hope and optimism about their prospects beyond decommissioning. We can do this by working in partnership with the trade unions, Highlands and Islands Enterprise and others, and I am delighted by the response so far from the workforce to this new initiative.” Restructuring – first regulatory agreement A major milestone on the route to restructuring was achieved in September, when the NII signed the agreement for Windscale to start implementing its reorganisation, enabling Windscale’s integration into Sellafield. It will also allow the start of shadow working in October. “As the first agreement received by UKAEA for site restructuring, this is a key advance in our programme for relicensing” said Norman Harrison. “It represents the culmination of an immense amount of effort by staff and means we can now start putting plans into practice.” Peter Mann, Head of the Windscale site, added his thanks. “A lot of hard work has been done by a lot of people, hand in hand with our Sellafield colleagues, to reach this position and I am delighted by this news.” The agreement followed the submission of the necessary documentation to explain and justify the proposed reorganisation - arrangements are being made for relevant documents to be available for view on the Intranet. Meanwhile, in September NII inspectors were at Dounreay to check their readiness for reorganisation, and it is expected that agreement for their changes will not be far behind. The necessary submissions for Harwell/Winfrith’s reorganisation have also been made to regulators and discussions are in hand on the logistics of their implementation. UKAEA Chairman Barbara Thomas Judge spent a day at CEA Cadarache in August. As well as visiting the CEDRA radioactive waste treatment and storage facility and a laboratory for the manufacture of U2 fuel in the fission sector of the site, she also toured the French fusion experiment Tore Supra and ended her visit at the ITER offices, where Nominee Principal Deputy Director General Norbert Holtkamp gave a presentation on the current status of the project. Busy time for ‘blue hats’ The ‘blue hat’ review teams from Dounreay, Harwell and Winfrith were busy in September, working alongside staff from Sellafield and Magnox sites, assessing possible options to go forward for shared service arrangements. This is part of previously reported plans for greater sharing of support services between all Site Licence Companies and the NDA. Evaluation ‘Blue hats’ are site representatives who undertake an initial evaluation of the potential of different services to be shared. They considered about a hundred such areas, including some like nuclear materials accounting where UKAEA could play a leading role, and identified some 20 which they thought merited further consideration. If agreed by the Shared Service Steering Group, the suitability of these services for sharing will next be considered by teams of ‘gold hats’ (experts in the relevant field from the sites) before being put through their final mill by ‘black hats’, whose role is to challenge and test the shortlist. Only after completing this increasingly intensive scrutiny will action be taken on the selected areas under the shared services arrangements. Changes to company bonus arrangements UKAEA has announced some changes to the company bonus arrangements for this year. To take into account the restructuring of the company, the split between corporate and divisional measures has been reversed, so it will now be 5% divisional and 2% corporate. The corporate measures have been reviewed. Though the overall formula remains similar to previous years, the new arrangements will be: 1.6% measured on NDA performance (fee) and 0.4% on Fusion performance. These will be multiplied by the combination of the safety performance measure and environmental performance measure to give the 2% total. The media performance measure has been dropped. Safety As in previous years, the bonus would be reduced to zero if there were to be a fundamental failure of safety, such as an incident at INES (International Nuclear Events Scale) Level 3 or in the event of a fatality to a UKAEA or contractor’s employee resulting from culpable failure on the part of UKAEA. Details of the measures and targets for the divisional bonus schemes for 2007/08 are still being finalised. However, for employees in site teams, at least half of the divisional bonus of up to 5% of salary will be based on delivery of the site programme. October 2007 UKAEATODAY 3 Restructuring n Changes at the top n Archive visit CEO’s view of progress UKAEA CEO Norman Harrison’s diary may be full to bursting but he still believes it’s important to stop and take stock. He also believes it’s important that UKAEA employees know how things stand so he shared his thoughts on the latest position with UKAEA Today. The Excellence in Safety programme is already achieving a great deal, as Norman noted in his recent message to staff, with encouraging improvements in a number of areas. As ever, though, we must always be looking for further progress to our goal of zero accidents. Relicensing SLC progress towards relicensing is good. Norman had just heard that the NII had signed the agreement for Windscale to start implementing shadow working arrangements and the equivalent Dounreay agreement would not be far behind. “This is what we have been working for and it is great to see it starting to happen. I know it is disappointing that funding issues have affected progress on the Harwell/Winfrith relicensing, but it is to everyone’s credit that planning is advancing well.” UKAEA Ltd, the commercial arm, is also looking forward and the steady stream of new contracts will be given more publicity. “We Plans are also progressing for the relocation of HQ staff out of B521 at Harwell. Although potential new office accommodation has been identified, the lease has not yet been signed. Norman Harrison are keen to grow our business both here and overseas, which will also attract media attention – even if it isn’t always accurate! For commercial reasons, we won’t always be able to comment on such coverage – this may particularly affect us during the Dounreay competition – but we will want to tell staff about new business wins as soon as we can.” Workshops on the new way of working are being arranged over the next few weeks for all employees destined for UKAEA Ltd. “After that, there will be the chance of one-to-one interviews for people to discuss their UKAEA Ltd terms and conditions,” said Norman, “although please bear with us, as it will take some time to get to everyone.” A million pictures and counting… In excess of a million images and miles of moving footage with more arriving every day, that’s the score so far at Harwell’s photographic archive. Terry Selby, Strategy Director of NDA, and his colleagues Simon Tucker and Pip Hatt came to see for themselves in August. Records Terry Selby, who is responsible for a range of NDA activities, including strategy, socio-economic plans and stakeholder relations, visited the written and photographic archives in Building 404, in connection with another facet of his role – records. “It was fascinating,” he commented. “These records are essential to our decommissioning task but they are also our heritage and, as we develop our plans for a national nuclear archive, it was heartening to see such a well organised and managed operation.” Joint Venture Some other areas, in the future NDPB, may not be directly involved in these changes but are advancing in line with their own objectives. The arrangements to find a partner for the Joint Venture to run the Harwell campus, for instance, are now motoring ahead. And the fusion programme continues to play a world role, not least in preparations for the ITER project. Summing up, Norman said, “As CEO, having responsibility for the whole of UKAEA, I’m conscious that different areas have different priorities. At Harwell and Winfrith people’s primary concern is inevitably and quite rightly the future for them and their jobs. At Windscale, it is the integration with Sellafield. But one thing is the same throughout UKAEA; everywhere I go, I still see people successfully getting on with delivering the job safely, and that is the most important thing of all. I want to thank everyone for their tremendous efforts during these changing times.” New Heads of Site arrangements With the retirement of John Wilkins as Head of Site at Harwell at the end of September, UKAEA has announced a new interim management structure. Interim The Research Sites Restoration Limited (RSRL) management structure is scheduled to begin in November. In the interim period, Alan Neal will take over as Head of Site at Harwell and Andy Staples will become Head of Site at Winfrith. Alan is currently Head of Site at Winfrith. He is a Chartered Physicist with an Alan Neal MSc in Radiological Health and Safety and has been at Winfrith since 1985 and Head of Site there since 1998. WOMAD Andy is currently managing all the decommissioning works at Winfrith. He graduated with a degree in industrial chemistry. His career in the nuclear industry has been wide ranging and most recently he managed the WOMAD project at Winfrith Andy Staples UKAEATODAY October 2007 4 Safety & Health Towards a culture of safety 2007 has brought a new focus on safety to UKAEA sites. In recent months, initiatives have been introduced to ensure the company maintains and improves its safety record. Everybody working on a nuclear licensed site can and should make practical contributions to safety How does the Health & Safety Executive (HSE), as the body responsible for enforcing health and safety regulation in Great Britain, view UKAEA’s approach to safety at this time of challenge and change? We spoke to Derek Lacey of the HSE’s Operations section. Q Can you explain your role within the HSE and your relationship with UKAEA? A The regulation of safety on the UK’s nuclear licensed sites is carried out by HSE’s Nuclear Directorate which is divided into six divisions. One of these divisions regulates safety on nuclear chemical and research sites and I have been head of that division since the beginning of 2007. Regulation of safety on the UKAEA sites is therefore my responsibility. Q Have you had a chance to visit any UKAEA sites? What are your general observations about UKAEA safety performance? Do you have any specific concerns at this time? A In July of this year I had a very informative visit to Dounreay during which I accompanied some of my colleagues on inspections and visited DFR, the Marshall Laboratories, the Dounreay Cementation Plant and the Enriched Uranium Processing Plant, and attended several meetings as an observer. During this visit I was able to see the results of considerable investment in decommissioning and also that the safety initiatives described by senior managers are evident on plant. I am, however, aware from our regular internal communications that safety performance on UKAEA sites has been variable and I would particularly welcome improvements in the production and review of safety cases. During this period of considerable change it is important to maintain a focus on nuclear and radiation safety and to continue to seek improvements wherever reasonably practicable. Q Do you see this as a critical time for UKAEA safety? Why? A I do think that the introduction of a competitive decommissioning market and the resulting organisational changes present UKAEA with new safety challenges. During this period we expect licensees to increase their focus on management of change and ensure that the capability to manage, operate and decommission safely is carefully guarded. This will require that responsibilities must remain clear for each individual and that everyone must remain focused on safety. Q At UKAEA we are taking steps to make sure we don’t ‘take our eyes off the ball’ at this time of change. Do you believe UKAEA’s Excellence in Safety initiative is the right one? Why? A We welcome UKAEA’s Excellence in Safety approach and believe it to be appropriate during this period of change. It is a recent innovation and my inspectors are monitoring its implementation. We believe that this approach has the potential to produce sustainable improvements in safety performance. the nuclear industry has been alert to the potential for learning from significant events and most recently it has acknowledged the relevant lessons from the Texas City refinery explosion; for example, the need to maintain investment in asset integrity and the inappropriateness of using good conventional safety data to imply adequate performance in nuclear safety. I think that the nuclear industry has fully recognised the link between culture and organisational performance. However, “getting the right safety culture in place” is sometimes an elusive challenge because of the range of measures necessary. We are focusing on the broader goal of “sustained excellence in management for safety and safety culture.” This recognises the need for effective leadership, the management of competence, effective organisational learning, the control of organisational change and the measurement of a comprehensive range of safety attributes to inform management decision making. Q What do you see as the main keys to improving safety? Better training, a change in company culture, improved safety documentation, better management and leadership or…? A All the suggestions you make can have an important part to play in improving safety and have been identified in your Excellence in Safety initiative. The main areas for improvement will however depend heavily on the specific hazards and risks to be managed on the different sites, the characteristics of the facilities and the recent safety performance. I believe that the arrangements put in place to satisfy the site licence conditions should provide valuable information to licensees which will help them to focus attention on specific areas which require improvement. Q If you could get just one safety message over, what would that be? A Everybody working on a nuclear licensed site can and should make practical contributions to safety. Safety visit Q What lessons do you think the nuclear industry could learn from other industries, in the UK and abroad? How important is it to get the right safety culture in place? There has been a tendency historically for the nuclear industry to be a little isolated from other high hazard industries which face similar safety challenges. I do, however, believe that During this period of considerable change it is important to maintain a focus on nuclear and radiation safety and to continue to seek improvements wherever reasonably practicable The Joint Safety Reps Forum, including reps from Harwell, Winfrith and Dounreay, completed inspections at Dounreay’s PFR, the silo and the Nuttalls/Ritchies project at the shaft, and submitted their reports to management. Dounreay’s Health Safety and Feedback Manager, Bill Stockho, welcomed the reps to the site and joined them over lunch to discuss improvements that had been made at Dounreay. Forum Chairman Peter Simpson commented that it had been a worthwhile visit. The team were impressed by the work being undertaken both in PFR and at the shaft. He was also impressed by the high commitment to safety shown by staff at both of these projects. October 2007 UKAEATODAY 5 Changing with the times: UKAEA’s Safety Document Assessment Department Two new recruits have been appointed to UKAEA’s Safety Assessment Department. Frank Phillips, who joined in August as a peer reviewer, and Rob Cook, who joins later in the year, will bring the number to 11. Eleven years ago, when it came into being – known then as the Peer Review Department – it had just three members: including Steve Peterson and John Anderson. “Our main role, established in the early days, included Category 1 and Category A safety case peer reviews for all UKAEA licensed sites, plus reviews for Culham, maintenance of safety case methodologies through the Safety Assessment Handbook, and safety case writing and peer review training,” said Steve Peterson. Its responsibilities have since expanded to include Category 2 and Category B safety cases, environmental documentation and some lower category safety cases. “Our first project in 1996 was the peer review of the operational safety case for B220 at Harwell. In late 2006, we began our 500th review project, a Category B modification to Windscale’s B13 building,” said team leader John Anderson. “We’ve come a long way since those early days. Over the years we’ve expanded our capabilities and have been successful in winning nuclear and non-nuclear work from a diverse portfolio of customers.” Some recent high profile cases on which the department worked were the upgrade of the DFR Goliath Crane, the Pile 2 Frank Phillips Rob Cook Isotope Cartridge Removal project and the Pile 1 endoscope survey project. Courses Another departmental responsibility, the development and delivery of the UKAEA Safety Case Writers’ courses and the Peer Reviewers’ courses, has proved popular with UKAEA staff and contractors alike. To date, more than 500 people have attended the Safety Case Writers’ courses and over 400 have attended the Peer Reviewers’ courses. New generic versions of the courses have given them an even wider application. Courses are held in the Warrington area and can be run on request. Team members are also involved in other safety activities including membership of safety working parties, process development teams and the cross industry Peer Review Forum. Safety Document Assessment Department team members have a wide variety of skills, ranging from safety management, engineering, chemistry and physics to radiological protection, criticality, environmental and transport safety. They are based at Warrington, Harwell, Windscale and Winfrith. “The department has continually evolved over the past 11 years and there’s no doubt that its future will be different from the past. We’re looking forward very much to continuing to work with our existing customers and taking on new challenges,” concluded John Anderson. Some members of the Safety Document Assessment Department Back row: Alan Rudge, Jim Williams, Ian Munn, Steve Peterson, John Anderson Front row: Mike Harrison, Fiona Boyer, Jackie Wilkinson, Mark Janicki Chernobyl team visit Front row (l to r): Volodymyr Medintsov, Andrii Bilyk, Igor Gramotkin, Volodymyr Beznoshchenko and Volodymyr Gavrysh. Back row: Sandy McWhirter, International Marketing Manager, Randall Bargelt, NDA Senior Site Programme Manager/Deputy Director and Simon Middlemas, Dounreay Director A management team from the Chernobyl Nuclear Power Plant in Ukraine spent a week at Dounreay in September, learning how Britain is decommissioning its fast reactor programme. The primary interest of the delegation was to share and compare the experience of Chernobyl in managing the change from reactor operations to decommissioning. This includes learning from the steps being taken at Dounreay to retain a suitably skilled and qualified workforce for the duration of the decommissioning programme and how the local economy can be sustained beyond closure. Dounreay and Chernobyl are both located in relatively remote locations, so face similar social and economic challenges during their transition from operation to closure. During their five-day visit, the delegation visited various facilities at Dounreay being decommissioned. They met programme managers responsible for the £2.9 billion site clean-up plan, held discussions with the Nuclear Decommissioning Authority and spoke with site officials helping local development agencies plan for life after Dounreay. They also visited the North Highland College, Thurso, to learn about its role in the delivery of training and reskilling for decommissioning workers. Sandy McWhirter, UKAEA’s International Marketing Director, said, “UKAEA is internationally recognised as a leader in managing the shift from operations to safe decommissioning. Visits such as this enable us to demonstrate our skills and experiences and to gain an insight into the challenges and opportunities that exist.” Alan Scott, NUKEM’s Decommissioning Project Manager at Dounreay, said, “The feedback from Igor Gramotkin and his team has been very positive. They were very grateful for the opportunity to share information and learn from the Dounreay experience. Although the problems of the Chernobyl site are different to those at Dounreay, the methods of managing those challenges are very similar.” 6 UKAEATODAY October 2007 Dounreay n Apprentices n DFR n Particles Particles consultation makes progress The final touches are being put together for the last stage of the public consultation for dealing with particles in the environment. Following a review of information gained from consultation, technical studies, test and trials, independent expert reports, improvements in monitoring technologies and the knowledge gained by offshore mapping surveys, the project team are now in a position to come forward with a preferred way forward which they believe will be environmentally and publicly acceptable. Extensive Phil Cartwright, Land Contamination and Particles Manager, said, “We have carried out extensive consultation over the past two years, providing up-to-date information at every stage to ensure that everyone who took part was provided with independent and factual information to allow them to voice their views. Dedicated “A considerable amount of work has been carried out by a small dedicated team and we are now in a position to come forward with our preferred clean-up strategy which will be published very soon. Comments on the draft Best Practicable Environmental Option (BPEO) study will be invited before we finalise the study and open discussions with SEPA and other key agencies to take the final preferred option forward.” New apprentices begin their training UKAEA and JCL welcomed 10 new apprentices to the Dounreay site in August. The youngsters were introduced to the realities of life at Dounreay, as they went through site and safety induction courses, health checks, and began their practical training. UKAEA’s Apprentice Training Manager, Jim Swan, explained the apprentices’ training schedule. “They will spend a few days on site and will then go to the North Highland College to study for a National Certificate in Engineering, as the first part of their four-year training programme. They spend three years on site doing practical training, backed up by academic work on day release to the College. “By the time they qualify, the UKAEA apprentices will have achieved a range of academic qualifications in engineering and nuclear decommissioning skills. So they will be very busy for the next four years!” Vi Blumfield oversees the training of JCL’s apprentices. She explained that JCL and UKAEA apprentices train side by side, but each company is responsible for arranging the placement of their own trainees for the practical training. “It’s a measure of the quality of the training programmes that we continue to attract large numbers of youngsters wanting to do an apprenticeship at Dounreay”, she said. “A Dounreay apprenticeship is widely recognised and highly thought of by other sectors of industry.” Good progress on DFR breeder removal plant The DFR breeder containment building, an imposing metal clad structure adjacent to Dounreay’s famous sphere, never fails to impress. Visitors can’t help but feel the sense of teamwork and achievement as the internal construction phase of the project rapidly progresses. The building is being kitted out with crucial equipment to handle and process the breeder elements from the fast reactor. Large concrete walls have been erected, including the installation of a 20tonne shield door, to house equipment for dismantling the breeder elements. Once the cladding is removed and the uranium slugs exposed, work will start on preparations for washing and packaging them into 500 litre drums ready for storage. The installation of electrical services is progressing well. Rails that will manoeuvre the trolley to transport waste drums containing the breeder elements have been installed, sitting like tram lines along the length of the building floor. Two members of the project team have been to Toulon, France, to undertake inactive commissioning trials and training on the retrieval cell mock-up unit. This is the equipment that will remotely remove the breeder elements from the reactor vessel. The next significant step will be the cutting out of a section of the DFR sphere, prior to the installation of a transfer tube later this year. The tube will allow the breeder elements to be moved from the sphere to the containment building. Internal building works are expected to be completed this year, with inactive commissioning due to begin in 2008. The work on site is being undertaken for UKAEA on behalf of the Nuclear Decommissioning Authority by ALSTEC, supported by local contractors. The breeder removal is due to start in 2009 and will take approximately three years to complete, subject to consents. October 2007 UKAEATODAY Dounreay n 7 PFR n Beyond Dounreay New PFR facility to clean up reactor The Sodium Inventory Disposal (SID) facility was officially handed over to Prototype Fast Reactor Operations on 6 September. The facility, which recently completed active commissioning, was designed, built, and safely commissioned by the Alkali Metal Residue Removal (AMRR) alliance, comprising UKAEA, JGC, Alstec and Jacobs. This symbolises a major step forward, as it provides UKAEA with the capacity to start cleaning sodium and NaK contaminated components stored at the PFR plant. The pioneering facility, constructed within the Sodium Tank Farm, uses the Water Vapour Nitrogen (WVN) process developed at the Janetstown Off-Site Test facil- ity to remove tritiated alkali metal residues from plant and vessels made redundant by decommissioning work on the Dounreay site. The alkali metal stores at PFR are currently reaching capacity, meaning that future decommissioning work was threatened with delay. The SID facility is scheduled to start processing this backlog of historic waste, freeing up space to allow future decommissioning to commence. The first job for the facility, which is to be operated by Nukem, will be to process sodium contaminated metal pipe components, known as complex geometry. Sodium inside the pipes is melted out inside the SID2 vessel, exposing all surfaces and sodium to the WVN mixture. The waste output is in the form of clean metal and a neutral saline solution. Following successful operations, there are future plans to adapt the facility to allow cleaning of the four remaining sodium tanks within the PFR plant in preparation for dismantling to begin. Beyond Dounreay: Caithness Conference Energy Minister, Malcolm Wicks and Minister of State for the Scotland Office, David Cairns, visited Caithness on the 14 September to attend the Caithness Conference entitled ‘Beyond Dounreay’. Organised by the Dounreay Stakeholder Group and Caithness Partnership, over 130 delegates attended the event, designed to allow stakeholders to input into the draft action plan for delivering a new economic future for the area. Impressed Following the workshop session, Malcolm Wicks commented, “I’ve been enormously impressed by the conference and have been very struck by just how many key players in this area have come along. The community are approaching this big challenge with confidence and I sense a can-do attitude which can only lead to a successful future.” Dounreay’s Donna Stewart and June Love, representing Dounreay Stakeholder Group, were part of the organising committee, along with Anna MacConnell of Caithness Partnership and UKAEA, in support of the NDA, provided a third of the funding. Useful Dounreay Director Simon Middlemas also played a prominent role, chairing one of the workshops. Following the conference, Simon said, “This was a very useful day. While we recognise that regeneration of the area is not our responsibility, we do have a supporting role to play. “By 2032 we want to have about 2,000 jobs in the supply chain, the local firms and almost none at UKAEA. I feel passionately about this because I am part of this community. I live here, I work here and I want to retire here. “Dounreay has been at the heart of the local economy for a long time and we owe it to the community to help plan for a life after Dounreay.” Members of Dounreay Union attend the conference 8 UKAEATODAY October 2007 Culham n Fusion film n Golden Spanner green.tv Apprentice of the Year Kate Winstanley, a first year apprentice at Culham, has been named Apprentice of Year by Abingdon and Witney College, Oxfordshire. Kate was presented with The Golden Spanner Award as the most promising engineering apprentice attending the college. Talent Internet TV channel green.tv paid a visit to Culham in August to make a short film on the potential of fusion to provide clean energy in the future. green.tv is dedicated to environmental issues and particularly focuses on climate change. It is the latest in a succession of media outlets to cover the research at Culham as the energy debate hots up and word spreads about fusion’s advantages. Culham scientists Duarte Borba and Melanie Windridge were interviewed for the film, ‘A future in fusion’, which can be viewed at www.green.tv. Winfrith n “Kate has demonstrated natural talent, hard work and application to win this award,” said David Martin, Manager of the Apprentice Scheme. “All the team involved in starting and running the Culham apprentice scheme should share in the sense of pride at Kate’s achievement, which is also a credit to their contributions to the scheme.” The Culham apprentice scheme, which aims to maintain the engineering skills base for technicians on site, restarted in 2005. Kate is presented with her golden spanner by lecturers from Abingdon and Witney College. Further details can be obtained from Anna Barns or at www.fusion.org.uk/apprentice/home.htm History recalled n BTCV Wool School revisited Six months after UKAEA staff helped build a wildlife garden at Wool Church of England Primary School, UKAEA Winfrith Communications Manager Emma Burwood was invited back – Groundforce style – to see how the garden was faring. Staff had teamed up with the British Trust for Conversation Volunteers (BTCV) to clear the garden and create vegetable beds and pathways for the children. “It was lovely to see the children had grown their own vegetables and flowers in the raised beds we’d built,” said Emma. “And the school had raised funds to buy a sundial and have a summerhouse built. It all looked very impressive.” Fifty years of Winfrith history remembered A brochure showing the history of the Winfrith site from 1957 to the present day has been published. The publication charts the Winfrith story from the beginning of construction in September 1957 through the golden years, when a range of research and experimental reactors – from Zenith, Zebra and Dragon to SGHWR – were operational, right up to 2007 and the accelerated decommissioning programme. Memories The Apprentice Training School, the delicensing of the first section of land on the site, and the creation of the Winfrith Technology Centre are all remembered, in words and in pictures. There are memories too of some famous visitors to the site, including the Queen and the then Secretary of State for Energy, Cecil Parkinson. If you would like a copy of ‘UKAEA-Winfrith at Fifty’ please contact Emma Burwood on 01305 203107 or e-mail emma. burwood@ukaea.org.uk October 2007 UKAEATODAY Harwell n 9 Donation n On location n BPEO WEP moves into the next phase Construction of Harwell’s Waste Encapsulation Plant (WEP) is nearing completion. The plant, which will enable UKAEA to process Intermediate Level Waste (ILW) from the B462 storage facilities, is scheduled to be fully operational by mid 2009. As the construction phase nears completion, the project is moving into its next phase, mechanical and electrical installation. “On-site electrical installation works have already commenced, with mechanical installation of the process plant soon to follow,” says Senior Project Manager, Jim Cornish. Off site, works testing is now complete for the last of the mechanical packages. Off-site testing has given the project team the chance to directly involve the operators, who will eventually run the plant, using their operational skills, assistance and experience to help advise on plant operability, as well as providing early training. “The successful completion of works testing of all of the mechanical and electrical plant is testament to the value of UKAEA’s input at all stages of scheme design, detailed design, and manufacture. “With the changing environment and numerous diverse installation trades, safety continues to be at the forefront of the project planning, and the contract safety management strategy continues to evolve with continuous improvement being the site goal,” Jim added. Computer help for pre-school UKAEA Harwell has donated a computer that is no longer needed on site to a local pre-school. Marcham pre-school playgroup opened in 1969 and is a committee-run group situated next to the primary school in Marcham village. The pre-school provides young children with an education before they move onto the primary school. “With the help of the PC donated from UKAEA Harwell, on behalf of the NDA, the children can continue to improve their IT skills in an informal and friendly environment,” said Louisa Williams of Harwell Communications. Pullman film at Harwell Harwell BPEO update UKAEA has been carrying out a Best Practicable Environmental Option (BPEO) study for the management of wastes arising from the Harwell decommissioning and clean-up programme. . A First Stakeholder Consultation Document was issued in early 2007 to a wide range of stakeholders, including the Nuclear Decommissioning Authority, safety and environmental regulators, the Local Stakeholder Group, local communities, employees, members of the public and other interested parties. This sought views on options for waste management and the process for assessing options. A total of 22 responses were received. Since then, UKAEA, with the help of independent consultants, has assessed options for over 30 waste streams, a marathon task involving a range of experts from inside and outside UKAEA, including British Energy, British Nuclear Group, NDA Radioactive Waste Management Division and GE Healthcare. A Second Stakeholder Consultation Document is being issued in autumn 2007. This sets out the preliminary results of the assessment and shows how the views of stakeholders affect the results. It also includes stakeholder comments and UKAEA’s responses to the comments made during the first consultation. There will be a 12 week period of consultation. As part of UKAEA’s commitment to listening to stakeholders, a stakeholder workshop will be held, expected to be in late November, at which stakeholders and other members of the public will be able to express their views and find out more about the study.

The film, which tells the tragic story of Chris who meets Jenny, the love of his life at an Oxford college summer ball, is being made by the Dutch production company Dynamic Entertainment DEH. The Butterfly Tattoo was filmed on location in and around Oxford over a period of six weeks, with a predominantly young crew and cast.

The Windscale Piles operated from 1950 to 1957, when a fire caused severe damage to the core of Pile 1. In 1945, the British Government made the decision to build its own nuclear reactors. By 1946, a research establishment had been set up at Harwell and by 1947, construction of the Windscale Pile Reactors had begun. Pile 1 began operating in October 1950 with Pile 2 in June 1951. The Pile Reactors are massive structures which today can still be seen against the backdrop of the wider Sellafield site. During reactor operations, scientists noticed high abnormal temperatures, caused by so-called Wigner energy. To deal with the problem, a process known as annealing was used. By heating the graphite core above normal operating temperatures, the energy was released. Each anneal gave about 10 months of safe operations. As the eighth anneal of Pile 1 was incomplete and the first nuclear heating had released very little Wigner energy, a second heating was applied. This released energy so quickly that overheating could not be prevented and the reactor caught fire. Water was applied and this, combined with air starvation, cooled the core and extinguished the fire. Both Pile Reactors were closed and all operations ceased. Clean-up activities started immediately. An accident inquiry was set up under the chairmanship of Sir William Penney. The Inquiry concluded that the second nuclear heating of Pile 1 had caused the accident. It criticised instrumentation deficiencies, organisational weakness and lack of operating manuals. The Fleck Committee was charged with undertaking a technical investigation of the accident. As a result of the fire, a plume of radioactivity escaped from the core via the chimney and out into the surrounding environment. It cooled and fell onto the ground. Affected by the prevailing weather conditions at Windscale, the plume was carried by the wind and detected in areas of Europe. UKAEA put in place a biological monitoring programme and started sampling milk from local farms, vegetation, soil grass and foodstuffs. Milk sampling showed a rise in Iodine 131 and a milk ban was put in place. Initially 17 farms were identified and an area of 80 square miles, later extended to 200 square miles. With Pile 1 beyond repair and Pile 2 unlikely to restart, the care and maintenance of the reactor and making both plants safe and secure became the primary objective of the team at Windscale. From 1957 to 1961, work was carried out to dismantle redundant equipment, insert the shutdown rods and control rods and take out the drive mechanisms. Both chimneys were sealed at the top, the filter gallery removed and the inlet ducts isolated. Between 1981 and 1999, significant clean-up work was carried out. The concrete biological shield was sealed which allowed the installation of ventilation and monitoring plant. Surveys identified an accumulation of fuel and isotope cartridges in the water and air ducts. These were safely and effectively removed and the water ducts cleaned. Phase 1 decommissioning was completed in June 1999, ensuring the plant remained in a safe condition until further decommissioning could be undertaken. Decommissioning Pile 1 is recognised as being technically challenging. Work from the 1990s to present day has focused on developing safe, secure and environmentally acceptable approaches to decommission the reactor. Innovative approaches have been considered and the manufacture and trialling of prototype equipment has been initiated. Equipment will be used to remotely remove the remaining fuel and isotopes from Pile 1. The reactor control rods and shutdown rods will be removed, followed by the Pile cap and the reactor core, prior to the removal of the biological shield. Where possible, waste will be processed, recycled or re-used. Where this is not practical, arrangements will be made for storage or disposal. Ultimately, the team at Windscale intend to decommission the site to brownfield status or to ground level. European Cooperation Nicolas Sultanem, of the French company Commissariat à l’Énergie Atomique (CEA) in Paris, recently spent ten weeks working on the Windscale Advanced Gas-cooled Reactor (WAGR) decommissioning project. Nicolas has been researching into a decontamination project, as well as successfully improving his English. The secondment was arranged through the close working relationship of Senior Project Managers, Terry Benest of Windscale and Michel Jean Jacques of Fontenay-aux-Roses, the birth place of the Nuclear Programme in France. Terry and Michel have been members of the Organisation for Economic Cooperation and Development’s Technical Advisory Group (OECD’s TAG) for some time. Nicolas said, “Spending time with the WAGR project team has given me more experience within the nuclear industry.” Nicolas added that he has been warmly welcomed by his colleagues at WAGR. He also thoroughly enjoyed getting to know the area. On returning to France in September, Nicolas began combining his practical experience at the CEA with part-time study at CEFIPA, an engineering college in the South of Paris. Speaking about Nicolas’ placement at WAGR, Terry Benest said, “Co-operation between UKAEA and CEA encourages a valuable exchange of knowledge and experience and it has been a great pleasure to host Nicolas at WAGR during his stay.” Compacting mountains into molehills An innovative technique is being used in Windscale’s Advanced Gas Cooled Reactor (WAGR) decommissioning project to compact asbestos waste. UKAEA, CH2M HILL International Nuclear Services (CHNS) and Hertel Services have developed and implemented the process of low force compaction for asbestos containing Low Level Waste (LLW). It uses a low force compactor in a carefully designed and ventilated containment structure to reduce the volume of the wastes and control the spread of either radioactive or asbestos contamination. Development work carried out on site has demonstrated that the process is safe, practical and efficient. Health and Safety Executive Field Operations Division (HSE FoD), Nuclear Installations Inspectorate (NII) and the Environment Agency (EA) have followed the development work with interest and are supportive of the conclusions of the study. The WAGR decommissioning project team proposed this innovative resolution to the problem of conditioning and disposing of asbestos-contaminated LLW arising from the dismantling of the WAGR pressure vessel. These wastes comprise broken pieces of insulation block and the cement-based compound, as well as Personal Protective Equipment (PPE) and waste equipment arising from removal operations. When not associated with the steel of the pressure vessel or other activated steel contaminants, such waste has low activity and may be handled manually. This strategy currently represents the Best Practical Means (BPM) for disposal of asbestos contaminated wastes currently stored and those that will be produced in the future through decommissioning activities.

Websites to help you go green Want to de-clutter a room or furnish one for free? Freecycle could be the answer. The worldwide network of Freecycle centres takes the idea of recycling a step forward by introducing a new take on the bartering principle. Freecycle groups match people who have things they want to get rid of with people who can use them. The aim is to reduce the volume of usable items that go into landfill. The first UK Freecycle group was set up in 2003. Now there are 444, all run by locally based volunteer moderators across England, Wales, Scotland and Northern Ireland. How does it work? Everything posted must be free, legal and appropriate for all ages. If you have something you want to offer – from a tea-set to a drum-kit – you send an email to your nearest group, which you can find via an online locator. If you want to get hold of something, you post a message detailing what you’re looking for. The giver then decides who receives the item – and no money changes hands. If you want to dispose of unwanted items in a more conventional manner, try the recycle-more website, which includes a bank locator. Visitors to the site can search for their nearest recycling bank by postcode and waste type. recycle-now also offers a wealth of hints and tips about recycling, from how to set up a recycling system in the workplace or at school to the mechanics of the composting process. Filling in a waste diary may bring home just how much we throw away each day. http://uk.freecycle.org www.recycle-more.co.uk Please remember that the Website of the Month feature suggests websites you might like to access from your home computer.

Mike’s friends will know that his diary of the event is not for the faint-hearted. These are some more conventional extracts: “20th August, 15:07: Seven hours before the start and the tension is horrendous. This event is massive in France. Overall it is 760 miles over four days. The total amount of climbing is 33,000 feet. “21st August, 16.34: The start was a festival. Fireworks were interesting. I could’ve done without the bagpipes. Lots of people lined the streets and bridges. Well-wishers even at 2.30 am. We are now at the 200-mile mark. Please can the sun shine! “24th August, 08:46: Done 900K out of 1200K but have knackered my knee. Pedalled 50 miles using only one leg. “24th August, 09:17: Just made last control. Very short of time but had to stop for a sleep twice or I’d have fallen off. Paris next stop. I’ve got five hours to get there.” “24th August, 14:07: Just got in. Mission accomplished. Enjoyed it so much, ready for a second lap.” Retired Dounreay Head of Safety, John Walford, recently took the chance to visit Dounreay’s former plutonium criticality building for the last time before its demolition. John is one of two surviving members of the project team who supervised the first nuclear criticality in Scotland on 13 August 1957, which took place in the building next door. Dounreay built the facility, codenamed D8550, to carry out a major programme of criticality experiments on plutonium-bearing materials for the benefit of the UK nuclear industry as a whole. During his visit, John was impressed by the decommissioning work carried out by the project team. Project Engineer Alan Farquhar said, “Their example shows that even the most contaminated of build- First run in 1891, the 1200K Paris-BrestParis Randonneurs is the oldest cycling event still taking place on a regular basis on the open road. It’s organised every four years by the Audax Club Parisien as a test of cycling agility and endurance for tough amateurs. This year’s PBP was held on 20-24 August. ings can be decommissioned safely and efficiently.” Standing inside the vast 7m high, 8m wide cell, now completely empty, brought back memories. “The last time I was inside here was in December 1962,” John said. “I have enjoyed looking round all the other parts of D8550, especially as I contributed to the design of the facility and watched it grow during its construction, as well as being responsible for its eventual operation. I think of the time I spent on criticality work as the happiest and most gratifying period of my working life.” A garden to be proud of The John Lennon garden at Durness has been given a make-over, thanks to a team of 12 volunteers from the Dounreay site. The late Beatle spent summer holidays in Durness, Sutherland as a child. Dounreay’s Carol Miller, seconded on a part-time basis to the North Highland Tourism (NHT) Operators Group, appealed for help to get the garden tidied up before the John Lennon Northern Lights Festival in September. Some of the more greenfingered people from laboratory services, human resources and JCI decided that this would be a good opportunity for some team building and volunteered their services. After the work was finished Carol Miller said, “It’s amazing how much we achieved and we all worked so well together. The garden was originally created by the Breechgrove Gardeners in 2002 and has been maintained by local volunteers. “NHT hopes to allocate some of the proceeds from the festival to complete the task. The work carried out by Dounreay’s volunteers means that the garden is looking its best for the hundreds of visitors who are expected to attend the John Lennon Northern Lights Festival in September. Thanks are due to everyone involved.” A cheerful environment Leigh Hodgson from the Whitehaven in Bloom Committee, Fee Wilson Windscale’s Communications Manager, Cllr Henry Wormstrup, Copeland Councillor for Whitehaven Harbour Ward and Windscale’s Claire Tandy with children from Monkwray School who planted the flower bed pictured behind The Windscale Head of Site Community Fund recently supported the ever-popular Whitehaven in Bloom competition, by making a donation which allowed local schoolchildren to spend a day planting flowers in Trinity Gardens in Whitehaven Town Centre. The schools event, which has now been running for five years, encourages children to take pride in their local environment. This year, 10 schools from the Whitehaven area became involved, with more than 150 children taking part. They all thoroughly enjoy the day.
