A presentation to the Spent Fuel Management and Nuclear Materials Working Group of the West Cumbria Sites Stakeholder Group Spent Fuel Management & Nuclear Materials (SFM&NM) April 2014 Update Stan Baker, Head of Business, Spent Fuel Management
12 October Recap: The NDA Mandates given to SFM Complete the reprocessing of all Magnox fuels (Magnox Operating Programme known as MOP) –Processing of First Generation Spent Fuels which have provided significant and diverse contribution to UK and International generation capacity. Receive and process other NDA material. Complete Thorp reprocessing contracts by 2018 –Processing of Second Generation Fuels (Oxide fuels) - which have continued to provide significant contribution to UK and International generation capacity Interim safe store all remaining AGR lifetime fuel arisings –Receipt and interim storage of fuel from the current generation of UK oxide reactors. The planned lifetimes of many of these reactors are being extended Managed closure of the Sellafield MOX Plant –Plant rundown and Post Operational Clean Out of the first Sellafield MOX Plant –Available to receive Dounreay material December 2014 Hazard reduction and ongoing storage of plutonium bearing materials –Treatment of reprocessing products and storage of UK plutonium Operate the Wet Inlet Facility –The receipt and storage of material from customer

SFM Headlines January to end of March 2014 The Magnox Reprocessing revised forecast for 2013/14 of 550Tes was not achieved due to a number of plant issues within the Reprocessing facilities. The revised year end Thorp shearing target of 335Tes was exceeded - A significant achievement in the final weeks of the financial year which saw an average of 18% uplift in AGR weekly processing rates. The AGR programme achieved its dismantling target with healthy skip stocks. Fuel receipts from the stations were disrupted during March due to a suspension in fuel movements imposed by edf to enable the re-licensing of the transport flasks. The MEB removals and Boral insert removal work target was exceeded. Progress towards achieving the ability to caustic dose the pond was recovered during the period. In the Plutonium Management Facilities Receipts of both Magnox and Thorp material exceeded the in year performance plan with sufficient product storage space available to support reprocessing. The Plutonium store consolidation programme achieved its targets early. The refills and transfers target were not achieved due to delays in the return of analytical results and delays in regulator approvals.
SFM year end summary was a challenging year for SFM -Magnox Reprocessing shutdown unexpectedly because of a blockage in the ferrous sulphamate line -An earlier than planned outage in the Thorp plant was taken in support of Evaporator C inspection -Given the above, we achieved the revised targets and continued to support the strategic imperatives of our programmes. -The blockage in the Magnox Reprocessing plant was cleared successfully -Support to high hazard reduction programmes continued -SFM Post Operational Clean Out (POCO) Operating Unit was established and is preparing for the end of reprocessing. -The Magnox throughput improvement programme (MTIP) continues to deliver enhanced risk mitigation and restore capability. -Thorp delivery assurance programme (TDAP) was created and delivered to NDA
Magnox Reprocessing Strategic Aim and Key Milestones The managed closure of the fleet of UK Magnox Stations and the receipt and treatment of other NDA material. End of reprocessing between 2017 and 2020 Impact of Performance on Strategic Aim The original target was 664Tes but this was reduced throughout the year as issues emerged with the ageing facilities. The target for this financial year of 520Tes is more realistic based on demonstrated capability and current performance when operating. The full year performance supports the range of end dates described above and exceeds the 450Tes “low case” in MOP9 Full Year Performance UnitsRevised Target 2013/14 Actual achieved Target 2014/15 Fuel Received (Tes) Fuel Reprocessed (Tes)
Ongoing Receipt of AGR Fuel Strategic Aim and Key Milestones Receipt and treatment or interim storage of fuel from EDF oxide stations. Station extensions being introduced into the plan. Receipt of lifetime AGR arisings until 2037 Implement dosing of Thorp Receipt and Storage pond in November 2018 to allow long term storage of AGR fuel when Thorp reprocessing ends Obtain licence and planning consent for long term storage Impact of Performance on the Strategic Aim The full year performance continues to underpin the Strategic aim of the AGR programme and the Thorp end-date of November 2018 Full Year Performance UnitsTarget 2013/14 Actual achieved Target 2014/15 Fuel Received (Tes) Fuel Dismantled (Tes) 180 MEB Removals
Thorp Reprocessing Strategic Aim and Key Milestones Reprocessing of UK and Overseas Oxide Fuel Complete Overseas fuel shearing (excluding MoX and PIE) by end of 2016 End of shearing November 2018 Impact of Performance on Strategic Aim The target for shearing at the start of the year was 423Tes, this was amended as the year progressed for various reasons as explained in earlier presentations The outturn was higher than expected given the operational issues experienced and continues to support the Strategic aim of completing shearing by November Full Year Performance UnitsRevised Target 2013/14 Actual achieved Target 2014/15 Fuel Sheared (Tes)
Safe Storage of Plutonium Strategic Aim and Key Milestones Treatment of reprocessing products and storage of UK plutonium Identified stores empty December 2014 Re-treatment plant available 2022 SPRS extension available 2032 and 2044 Impact of Performance on Strategic Aim Performance continues to support delivery of the key strategic milestones. Full Year Performance Plutonium Finishing Lines continued to fully support reprocessing demand, stores consolidation and cross site transfers. Sufficient product storage space available to support MAGNOX and THORP reprocessing for the financial year
Overseas Plutonium Return (SMP) Strategic Aim and Key Milestones Plant rundown and Post Operational Clean Out Operational rundown complete December 2014 POCO operations commence November 2014 Available to receive Dounreay material December 2014 Impact of Performance on Strategic Aim Programme delivery is on line to meet the key future milestones. Full Year Performance Performance continues to be in line with the schedule.
Wet Inlet Facility Strategic Aim and Key Milestones The receipt and storage of material from customer Maintain and store received fuels to ~2042 Complete transfer of fuel from old pond to new pond by 2020 Impact of Performance on Strategic Aim The flask transfer forecast was decreased to 15 following the deferral of some specific fuel consignments and the cancellation of a previously planned plant trial reconfiguration. Performance continues to underpin the strategic aim. Full Year Performance UnitsRevised Target 2013/14 Actual achieved Target 2014/15 Flask Moves (Number) 15
Operations Division Spent Fuel management is now part of Operations Division under the site’s Chief Operating Officer. The Key focus of Operations Division is to drive the completion of the Magnox and Thorp reprocessing programmes and the organisation is shaped to enable this. As the Operations Division Organisation develops individuals will be released to support the Decommissioning programme
