6 October Opening of the Meeting The CPD Chairman Jean-Guy Nokhamzon welcomed the participants, after which a round table presentation of the participants was made. Hans Riotte reminded the meeting that the current agreement expires on 31 December If the Board wishes to extend the term of the Agreement (in accordance with Article 10), it will be necessary to set this process in train during Decision: The Board decided that current agreement should be extended for a further 5-year period (from the end of 2008) and that letters should be sent to each of the current participants explaining the position and inviting them to confirm their continued participation. The Secretariat was asked to issue these letters in sufficient time that the process could be completed by the time of the 2008 Board meeting. [ACTION: SECRETARIAT] 2. Adoption of the Agenda Decision: The agenda [NEA/RWM/CPD(2007)1] was adopted. 3. Approval of the Summary Record of the Twenty-fifth Meeting (third meeting under the new agreement) Decision: The Summary Record from the CPD Management Board meeting October 26, 2006 [NEA/RWM/CPD(2006)4] was approved. 4. Current Projects under the Agreement Robert Burton made a presentation of the revised list of projects participating in CPD (reproduced in Appendix 2). He said that three new candidate projects were presented for consideration at the most recent meeting of the TAG, being the Barsebäck NPP, the Studsvik research reactors and the Bohunice V1 decommissioning project. These applications would be determined under Item 7 of today s agenda. The TAG meeting had recommended that the Studsvik and Bohunice projects be invited to join the programme. As regards Barsebäck, they did not make a recommendation but asked the Board to note that there would be some delay before major dismantling activities took place due to the lack of a waste disposal facility. Decision: The Board decided that the project listing (both completed and ongoing projects) maintained by the Programme Coordinator which was published in the recent CPD report A Decade of Progress in (a) tabular form and (b) one-page summary descriptions - should be generally updated. This updating should include (1) a check on the accuracy of the current information, and (2) information on new projects entering the programme. [ACTION: ROBERT BURTON] 6

7 5. Financial Statements Robert Burton said that the contract for CPD Project Coordinator was scheduled for completion on 31 December The contract for Task Group coordination would continue until The total cost of both contracts for FY 2007 was in the order of Hans Riotte said that the budget situation for the programme, as of the date of this meeting, was that there was a surplus of Contributions for 2007 had been received from all participants, including a small backlog from He said that outstanding invoices for CPD project coordination activities would reduce the current surplus to about by the year end. This positive balance meant that contributions at the current level would be sufficient to maintain a positive account balance through Decision: The Board decided that the contribution levels by participants for 2008 should remain at 3000, and that the relevant invoices should be issued shortly. [ACTION: SECRETARIAT] 6. Ongoing Work of the Technical Advisory Group (TAG) Bob Burton gave a presentation of the current work status of the TAG, see Appendix 3. Two meetings of the TAG were scheduled to take place during 2007: TAG-42 (Madrid, 7 th -11 th May) and TAG-43 (Greifswald, 22 nd -26 th October). With the exception of the Prototype Fast Reactor (PFR) project at Dounreay, all projects in the programme were actively participating in the TAG meetings. Two new task groups (on remote dismantling techniques and on concrete decontamination and dismantling) started their work in May, having held kick-off meetings on 4 th May. Progress meetings had taken place in October. Both projects were on course to publish final reports during 2009, on schedule. It was expected that the Whiteshell Laboratories decommissioning project (AECL, Canada) will apply to join the programme in 2008 see agenda item 11. Sellafield Limited that consideration was being given to proposing that additional projects from Sellafield should also join the programme. Decision: The Board asked that Sellafield Limited discussed potential future participating projects at the forthcoming meetings of the Technical Advisory Group (TAG). [ACTION: ALAN PRESCOTT] Decision: The Board asked that UKAEA nominate a TAG project representative for the prototype sodium-cooled fast breeder reactor (PFR) at Dounreay. [ACTION: PETER MANN] Decision: The Board decided that summary reports of each TAG meeting should be posted on the CPD web page [ACTION: BOB BURTON/SECRETARIAT] Decision: The Board noted that the work on the current task groups (on remote dismantling techniques and on decontamination/dismantling of concrete structures) would be completed in

8 7. Proposed new CPD Projects Patrick O Sullivan explained that the entry of new participants (i.e. organisations) to the programme required the unanimous approval of the Management Board. Once an organisation was admitted to the programme, a separate step was necessary to allow individual projects being undertaken by that organisation to be included in the programme. For this, Board approval by two-thirds majority was required. Following a review by the TAG, the Board was requested to decide on applications by Studsvik Nuclear AB and Barsebäck Kraft AB to join the programme, and for three new projects to be admitted to the TAG programme: (1) Studsvik research reactor decommissioning project; (2) Barsebäck NPP decommissioning project and (3) Bohunice VI NPP decommissioning project. Studsvik Bertil Josefsson presented the proposals relating to the Studsvik research reactor decommissioning project. The reactors had been shut down in June 2005 due to poor profitability and the need for large investment for continued operation. An immediate dismantling decommissioning strategy was being implemented, which would require that long-lived waste remained in storage on the site until about The ultimate aim was to return the site to green field status. Current activities were mainly concerned with putting the plant in a safe state until the start of dismantling work; planning the decommissioning programme and managing the necessary reductions in staff numbers. Barsebäck NPP decommissioning Leif Roth presented the proposals relating to the Barsebäck NPP decommissioning project. The reactors had been shut down November 1999 (Unit 1) and May 2005 (Unit 2) as part of the Swedish phase-out from nuclear energy. Since closure, the spent nuclear fuel had been transported off site to the CLAB interim storage facility and a survey of radioactivity in the plant had been undertaken. The current phase of activity (service operation) was concerned with preparing the plan for final dismantling, which was scheduled to begin in The intended end point of the decommissioning work was free release of the site for unrestricted use, including possible further industrial uses. Tasks currently underway included plant characterisation and decontamination, and packaging of operational wastes. Consideration was being given to removal, in due course, of large components as single pieces. Bohunice V1 NPP Decommissioning Jean-Guy Nokhamzon presented the proposals relating to the Bohunice V1 NPP decommissioning project. The V1 NPP, comprising two VVER 440 units, is being shut down in 2006 (Unit 1) and 2008 (V2) in line with an Agreement with the European Commission. The shutdown phase is expected to last until 2012, after which time dismantling operations could begin, following an immediate dismantling strategy. The total decommissioning cost of is expected to be 470 million, about one third of which will be spent during the shutdown phase, with funding provided by the European Bank of Reconstruction and Development. Current projects fall into three categories: Category A projects (e.g. removal of spent fuel; modification of heating and steam distribution systems) Category B projects (e.g. conceptual decommissioning plan and EIA report); and Category C projects (e.g. treatment and removal of operational waste from the site). Decision: The Board approved (1) the addition of Barsebäck Kraft AB and of Studsvik Nuclear AB as participants in the CPD Agreement; and (2) the inclusion of the Barsebäck NPP decommissioning project, the Studsvik R&D reactor decommissioning project and the Bohunice V1 project to the CPD programme. 8

9 October Future Contract for Programme Coordination Activities. The Board noted that the term of Robert Burton s contract runs from 1 st January 2006 through to 31 st December 2007, and therefore will shortly expire. Members were generally satisfied with the current arrangements and expressed a desire to continue the present arrangements for a further two-year period, on the basis of the same terms and conditions (including remuneration) as currently apply. Decision: The Board decided that, subject to compatibility with OECD contracting rules, Robert Burton should be offered a 2 year extension of his current contract, on the same remuneration terms. The Secretariat was requested to implement this extension. [ACTION SECRETARIAT] 9. Specially Invited Reports - IAEA Michele Laraia described the current decommissioning programme of the IAEA, including activities aimed at facilitating the transfer of sustainable technologies for the decommissioning of facilities, especially research reactors and smaller nuclear installations. He reported also on activities aimed at improving safety for decommissioning projects, such as the Research Reactor Decommissioning Demonstration Project, the DESA (Evaluation and Demonstration of Safety for Decommissioning) and an assistance project to the Government of Iraq concerning the former nuclear complex near Baghdad. Michele Laraia also described the launch of the International Decommissioning Network ( IDN ), which will provide a framework for the direct exchange of information between practitioners in the decommissioning field. The initial focus will be on small facilities such as research reactors and fuel cycle laboratories. Participating facilities that are suitable for demonstration or training are designated as Centres of Excellence. During discussion he confirmed that information exchanges were normally open and transparent, though confidentiality of information would be respected where requested. IAEA was keen to promote interaction with NEA/CPD activities and asked CPD to consider giving access to personnel from non participating countries to some of its activities. Jean-Guy Nokhamzon noted that a number of facilities were likely to participate both in the IDN and the CPD, thus providing an initial route for participation by non CPD participants, e.g. in scientific visits, fellowships, training (including hands on involvement with demonstration techniques). As regards formal CPD/IDN collaboration, this should be discussed further in due course, once the IDN is operational. Decision: The Board decided that the CPD should monitor the evolution of the International Decommissioning Network (IDN) planned by the IAEA and should be open to collaboration with this, in the event that suitable opportunities arose. [ACTION CHAIR/SECRETARIAT] 10. Potential Future Projects of the RWMC s WPDD Patrick O Sullivan described recent activities and publications of the WPDD (NEA Working Party on Decommissioning and Dismantling) see He said the forthcoming meeting of the Group would discuss proposals for three new project activities: setting up a sub-group dedicated to issues relating to cost estimation for decommissioning projects and an associated project on cost methodologies in current use; a project that will analyse current decommissioning experience to analyse lessons that may be 9

10 applied to the design of new plants; and a project to identify techniques that have good prospects for future development to provide reductions in worker doses, less secondary waste and/or improvements in time and cost of decommissioning. The Board noted the activities of the WPDD. 11. Proposed Future Work of the CPD Robert Burton said the Technical Advisory Group would meet in October at Heringsdorf (near Greifswald), TAG-43, and twice during 2008, provisionally in France and in Belgium. He anticipated that one new project would be proposed to join the programme at TAG-43, i.e. AECL s Whiteshell Research Laboratory (WRL) Decommissioning Project. In the event of a positive recommendation from the TAG, the project would be presented to the Board for approval at its next meeting, in The Task Group activities discussed under item 6 of this meeting would continue through 2008 and final reports would be produced in In line with normal practice, no further task group activity would be commenced whilst this work was underway. 12. Country Reports Japan: Hiroshi Rindo from JAEA presented a summary of decommissioning work in Japan. The main current activities are the dismantling of peripheral plant and building of the Tokai gas-cooled reactor plant; preparing the Fugen plant (Advanced Thermal Reactor) for decommissioning, and decontamination work at two JAEA fuel cycle facilities JRTF and a uranium enrichment facility. See - Current_status_JAPAN. pdf ). United Kingdom: James Whitehead presented a summary of decommissioning activities being undertaken by Sellafield Limited (part of BNFL). He said the diversity of the Sellafield programme requires a range of commercial arrangements. A Major Projects Group had been established to manage supply chain interactions, and current contracting policy favoured larger sub-contracts though site license duties were not sub-contracted. The major upcoming projects were: ponds and silos programme; decommissioning of the separation area; pile chimney demolition; decommissioning of Calder Hall NPP and contaminated land issues.

12 Appendix 2 Participating Projects (September 2007) A presentation was made to the Management Board in October 2006 by CEA (France) for acceptance of the Phenix project. Acceptance of this project into the CPD program was approved. Phenix is the 43 rd project in the Program. Three new projects were presented at TAG 42 for consideration. The Bohunice V1 NPP Project (Slovakia) received a positive recommendation for acceptance by TAG members. This project will be presented at this meeting for consideration to be accepted into the CPD Program. The Studsvik R&D Reactors and the Barsebäck NPP Reactor were presented by representatives from Sweden in observer status as neither of the owner organizations are members of the CPD. (Note both of these organizations have subsequently requested membership in the CPD). TAG members recommended acceptance of the Studsvik reactors (subject to obtaining CPD membership) but withheld comment on the Barsebäck reactor due to the long period of time before active decommissioning would commence. Currently there are 43 projects participating in the Program. The projects are listed below and are divided into two main groups: Reactors (27 projects). Fuel and other facilities (16 Projects). Each of these groups has been further subdivided into three categories: Category 1: Projects being worked on actively. Category 2: Dormant projects (in Stage 1 or Stage 2 ) Category 3: Projects that have achieved Stage 3 The projects are listed in alphabetical order of country and numbered to give a clear indication of the number of projects. At TAG meetings, attention is focussed on (but not limited to) projects in the first category. Participants normally give a presentation on their projects highlighting recent progress and technical achievements. 12

14 Appendix 3 Report on Tag Activities November 2006 to October 2007 The Technical Advisory Group has had one meeting since the last meeting of the CPD Management Board. The second meeting in 2007 will be held October and will be hosted by EWN in Germany near the Greifswald site. The 42 nd meeting of the TAG (TAG 42) was held in Madrid Spain from May 07 th to 11 th and was hosted by ENRESA. The first part of the meeting was taken up with progress reports from the various projects. There were representatives and presentations for 22 of the 31 Category 1 Projects. The second part of the meeting involved visits to three sites. The first visit was to the El Cabril Low and Intermediate Disposal Centre, currently in operation, and the Very Low Level Waste Facility, currently under construction. The other visits were to the CIEMET Centre in Madrid (Pimic project) and to the Zorita NPP Facility which will be the next decommissioning project that ENRESA will undertake. At TAG 42, a representative from Slovenske Elektrarne (Slovakia) presented the Bohunice V1 NPP Project for consideration of inclusion in the CPD Program. The TAG gave a positive recommendation. This project will be presented at this meeting. Also at TAG 42, representatives from the Barsebäck NPP Reactor and the Studsvik Research Reactors (Sweden) were invited in observer status to present their respective new projects to the TAG. The TAG members gave a positive recommendation for the Studsvik project but withheld comment on the Barsebäck Reactor due to the anticipated long dormant period. Neither of these parties are currently members of the CPD but both have officially requested to enter into the agreement. Both these projects will be presented at this meeting. At last years Management Board Meeting, two Task Groups were approved. Two meetings of these Task Groups were convened in Progress of these Task Groups will be reported in a separate report. At the last Management Board Meeting it was reported that some Organizations/Projects have not been represented at TAG meetings for several years. These organizations were contacted. All organizations have now officially named a Project Representative for their projects with the exception of the UKAEA/PFR Project. The next TAG meeting (TAG 42) will be hosted by EWN and held near the Greifswald Site. TAG 44 will be hosted by EDF in France and TAG 45 will be hosted by Belgoprocess in Belgium. The dates are to be determined. 14

15 Appendix 4 Technical Advisory Group (TAG) Program of Work for Introduction In respect of the CPD Agreement, effective 01 January 2004, the TAG will continue to function as the primary forum for the exchange of scientific and technical information between individual member countries for decommissioning projects. The Program Agreement provides provisions for the protection of information exchanged within the group giving opportunity for frank and open discussion in regards to methodologies, lessons learned, and problem solving. The TAG will continue this co-operative interaction to achieve a consistent international approach to decommissioning which in turn will result in cost effective execution of projects and assurance of project personnel safety, public safety, and protection of the environment. 2.0 TAG Meetings The TAG is an assembly of senior specialists from a variety of major decommissioning projects currently in progress in member countries. The TAG meetings bring these specialists together to present their projects, their progress, their discoveries and their problems. Time constraints at the meetings may prevent resolution to problems and issues at the meeting but the meetings facilitate postmeeting interaction for closure. Two Meetings are scheduled for The first meeting (TAG 44) will be hosted by EDF in France and the second meeting (TAG 45) will be hosted by Belgoprocess in Belgium. As usual, summary records of each meeting will be produced and posted on the CPD Member website. 3.0 Task Groups The TAG may address issues that are common and problematic to all projects by assembling a group of experts to form a Task Group to perform an intensive study of the problem and attempt to provide solutions (Task Group on Recycling and Re-use for example). Two such Task Groups were approved at the Management Board Meeting in October 2006: Task Group on Remote Handling Techniques. Task Group on Decontamination and Dismantling of Concrete Structures. These Task Groups were launched in 2007 and this work will carry over into It is anticipated that these task groups will wind up their work in New Projects New projects are normally introduced at the TAG meetings and evaluated for program suitability by the TAG members. Having passed this stage, the proposal is then presented to the CPD Management Board for acceptance. 15

16 Three new projects will be presented at this meeting for consideration and acceptance into the CPD Program. If accepted, they will then be introduced into the TAG agenda for the 2008 season. These projects, if accepted, will bring the total number of Category 1 Projects (Projects currently being worked on) to 32. This is a significant increase from the original 10 projects in The TAG will continue to actively promote the inclusion of new projects into the program in New projects will bring new experiences and add to the knowledge base for information exchange. 5.0 Reporting Reports of all TAG activities, including new Task Groups will be reported at the fall 2008 CPD Management Meeting. The 2009 TAG Program will also be presented at this meeting. 6.0 Process Improvement The objective of the CPD/TAG is to acquire information from the decommissioning of nuclear installations and disseminate this information (within the confines of the CPD Agreement) so that it can be used to improve efficiency in current and future decommissioning projects. The TAG will continue to monitor means and methods of collecting and disseminating this information. Potential areas of examination may include: Increased interaction/co-operation with other similar focus groups (WPDD/CPD interface for example) Increased interaction with international organizations Increased presence at conferences 16
