EPR UK N° NESH-G/2008/en/0123 REV. A PAGE 20 / 257 · The production of radioactive waste will be avoided and where this is not reasonably practicable, the quantity of waste produced will be minimised; · The radioactive wastes generated by the UK EPR are similar of those wastes generated by operating PWRs and all waste streams have process routes to interim storage or final disposal / solution; · A number of waste and spent fuel options to the FA3 Reference Case which are based on nationally or internationally proven technologies and the experience from EPR and AREVA projects are available for the UK EPR; · The dominance of short-lived radionuclides in some ILW will enable it to be declassified to LLW within the on-site interim storage period. The base case waste treatment facilities for each UK EPR site include: · Waste Treatment Building for the receipt, segregation, treatment and conditioning of solid radioactive wastes; · Interim Storage Facility for solid ILW packages; · Spent fuel Interim Storage Facility for receipt, packaging and safe interim storage of spent fuel. The facilities are modular in design and may be adapted to cope with future process changes and to maintain an appropriate capacity storage volume.
EPR UK N° NESH-G/2008/en/0123 REV. A PAGE 21 / 257 2 SCOPE OF THIS SOLID RADIOACTIVE WASTE STRATEGY This report presents possible solid radioactive waste strategies for the UK EPR programme. The SRWS identifies and describes the solid radioactive waste and spent fuel characteristics arising from the operating and decommissioning cycles or lifecycle of the UK EPR with respect to the current UK regulatory requirements. The operating cycle of the UK EPR is 60 years. It sets out management arrangements for processing and interim storage of the waste and spent fuel prior to ultimate disposal in accordance with UK regulatory requirements and the Government’s DWMP base case. For each waste stream generated by the UK EPR this strategy describes the “cradle to grave” waste route demonstrating the following: · No new or orphan wastes are generated by the EPR; · All waste streams are classified according to the current UK classification; · Waste is avoided or segregated at source; · Waste is minimised; · Waste is processed using proven and internationally recognised technologies and placed in standard packages for safe handling; · ILW from operations and decommissioning and spent fuel is maintained in safe and secure state until disposal; · Lifetime records are managed throughout the lifecycle. This strategy examines the processes and describes the facilities to process the wastes and provide interim storage of ILW and spent fuel. The main facilities and processes are listed below: A Waste Treatment Building to: · House processing and packaging systems for all operational waste streams produced by the reactor; · Enable processes which are installed to be removed and replaced in the future for more modern techniques; · Provide adequate buffer storage for all waste streams prior to processing and disposal; · Provide adequate space and handling for safe operation and adaptation for decommissioning activities; · Provide building modularity to cater for extension (although it would be also an option to build a separate store for decomissioning wastes). An ILW Interim Store to: · Store all ILW generated by reactor operations for up to 100 years after first fuel loading; · Provide building modularity to cater for extension and cater for decommissioning ILW (although it would be also an option to build a separate store for decomissioning wastes);
