EPR UK N° NESH-G/2008/en/0123 REV. A PAGE 18 / 257 FIGURE 1: RADIOACTIVE WASTE STREAM FLOW DIAGRAM Central to this SRWSR are four themes: 1. Avoidance of waste or waste minimisation; 2. Use of current UK practices or internationally proven technology; 3. Confidence that UK regulatory requirements for waste management and decommissioning are understood and can be implemented; 4. Flexibility within possible management options to address potential changes in UK waste legislation and Government Policy. The SRWSR describes how the generation of waste will be avoided or minimised where reasonably practicable. It takes into account the waste minimisation techniques that have developed through evolutionary design features of the EPR and demonstrates that the nature of the UK EPR operational waste is very similar to those radioactive waste streams produced by other operating PWRs. All of the UK EPR reactor wastes can be readily classified into the currently recognised UK waste categories. Further, the wastes generated by the UK EPR are fully enveloped within current UK waste management experience. The presence of relatively short-lived Intermediate Level Waste (ILW) provides an opportunity to significantly reduce (by on-site decay storage) the volumes of waste for disposal.
EPR UK N° NESH-G/2008/en/0123 REV. A PAGE 19 / 257 The requirement for quality assurance and record keeping over the UK EPR lifecycle is addressed in outline. The options presented provide a high degree of confidence that the waste and spent fuel can be treated and conditioned into a safe state pending final disposal (or an alternative final solution). Furthermore, the options provide confidence that waste and spent fuel can be safely stored, retrieved, handled and transported prior to disposal as practices evolve. 1.1 Exemptions, Assumptions and Uncertainties This SRWSR takes into account the liquid waste streams produced by a UK EPR which are delivered to the Waste Treatment Building for treatment and solidification. It does not address liquid and gaseous waste discharges, non-radioactive waste generated at the plant or wastes generated from the operation of the interim storage facilities. This SRWSR assumes that the UK EPR will commence decommissioning immediately after shutdown and de-fuelling, and describes the radioactive waste generated from the dismantling of the nuclear island. It does not take account of the non-radioactive waste generated from the decommissioning of the conventional island and administration buildings. It does not take account of the radioactive and non-radioactive waste generated from the decommissioning of the interim waste and spent fuel storage facilities. This SRWSR assumes that the options presented can be used by utilities to demonstrate that the design makes use of Best Available Techniques. The intention is to preserve as much flexibility as possible whilst providing confidence that BAT solutions can be identified by utilities in the future. This is judged to be sensible given the range of uncertainties at this stage. In particular, no specific sites for the UK EPR have been agreed and issues relating to the future treatment and transport of certain wastes need to be resolved with the UK Government and the Nuclear Decommissioning Authority (NDA). This SRWSR assumes that waste service providers will continue to be available to provide waste treatment and disposal serivices. It is anticipated that this SRWSR will be revised and updated and used as a basis to develop more specific strategies in the future. 1.2 Conclusions This SRWSR sets out management arrangements for processing and interim storage of waste and spent fuel generated by the UK EPR in accordance with the UK Government policy and regulatory constraints. The SRWSR provides a high degree of confidence that the challenges associated with the management of solid waste and spent fuel from the UK EPR are fully understood and that solutions are available with the envelope of current UK and international experience. Specifically it demonstrates that:
