In the UK the Office for Nuclear Regulation and the Environment Agency developed the Generic Design Assessment process in response to a request from the UK Government. The process allows the regulators to jointly assess new nuclear reactor designs, in advance of any site-specific proposals to build a nuclear power station. Two reactor types are currently being assessed within Generic Design Assessment: • AREVA and Electricité de France’s UK EPR® ; • Westinghouse Electric Company’s AP1000® . This paper will present the outcome of the assessment of radioactive waste management within the Generic Design Assessment process. One aspect of particular interest is the management of spent fuel from proposed new reactors as the assessment is based on an assumption that it will be sent for disposal. Therefore the paper will specifically consider the management of spent fuel and how this affects the regulatory decisions. The paper will look at four aspects. The first of these is to give a short overview of the Generic Design Assessment process. This will be followed by a summary of the Generic Design Assessment Radioactive Waste Management assessment on the acceptability of: • The types of waste and spent fuel. • The plans for conditioning of the wastes. • The safety issues associated with short-term storage. • The safety issues associated with long-term storage. • The issues associated with the disposal of the wastes. • The safety issues associated with decommissioning the reactors. The third aspect will be to look at the work commissioned by the Office of Nuclear Regulation in support of the Generic Design Assessment of radioactive waste management and how this has affected the regulatory decisions. This work has looked at the long-term stability of spent fuel in storage and the potential faults associated with the storage and handling of the spent fuel. The paper will end with the main conclusions of the radioactive waste management assessment within Generic Design Assessment. Looking at how storage of spent fuel can affect transport, disposal and decommissioning and how work by licensees could alter these conclusions.
