Feedback should be addressed to: iii Executive summary Background In 2009, the Nuclear Decommissioning Authority's Radioactive Waste Management Directorate (RWMD) contributed to the Generic Design Assessment process for new nuclear reactor designs. RWMD undertook assessments under contract on behalf of Westinghouse and Electricité de France and Areva NP, to consider the disposability in a geological disposal facility of the higher activity wastes and spent nuclear fuel (SF) that would be expected to arise from operation and decommissioning of the AP 1000 and UK EPR reactor designs. RWMD concluded that given a disposal site with suitable characteristics, the wastes and SF from the new nuclear reactor designs are expected to be disposable. The assessments noted that compared to legacy wastes and SF, no new issues arise that challenge the fundamental disposability of the waste and SF arising from new nuclear power stations. However, due to the higher burn-up proposed for SF in new nuclear power stations, a longer period of cooling had been calculated to be necessary to meet criteria for emplacement in a geological disposal facility. The assessments identified that various opportunities exist to reduce the required cooling period by, for example, considering options for the packaging arrangement and disposal configuration. Subsequently, prospective new nuclear power station …

Analysis of radionuclide release through EBS of conceptual repository for Lithuanian RBMK spent nuclear fuel disposal – case of canister with initial defect

At the Ignalina nuclear power plant (NPP), app. 22 thousands of spent nuclear fuel (SNF) assemblies from the RBMK-1500 type reactor have been accumulated [15]. During the operation of Ignalina NPP, the assemblies of SNF were stored in water pools and in storage containers, located in the interim storage facilities. According to revised Lithuanian Strategy for Management of Radioactive Waste [20...

Sfr Deployment Strategy for the Re-use of Spent Fuel in Korea

It is generally recognized that the spent fuel discharged from nuclear power plants constitutes the main contribution to nuclear waste. The management of spent fuel from nuclear power plants differs depending on the perspectives and scenarios posed by the countries directly concerned. However, there is a general consensus on the need for a deep geological repository and a reduction in the burde...
