EPR UK N° NESH-G/2008/en/0123 REV. A PAGE 36 / 257 AREVA and the utilities have proposed waste conditioning and packaging options to RWMD. The independent RWMD assessment results will be published in a Disposability Report in spring 2009. This publically available Disposability Report will outline the viability and practicability of the waste streams and package types proposed. 5.1.1.2 LLWR The LLWR is now managed by a new site licence company (LLWR Management Ltd.) who have recently updated and re-issued the Conditions for Acceptance for wastes consigned for disposal of LLW. This new guidance highlights the need for increased segregation, recycling, declassification and use of the Very Low Level Waste (VLLW) disposal route to prolong the lifetime capacity of the LLWR. In the future the LLWR could organise for combustible and metallic LLW to be collected from the site and transported to the chosen treatment facility. It may be that alternative waste service providers are engaged for incineration and recycling services. Under the management contract it is also the remit of LLWR Management Ltd. to formulate a long term strategy for the future management of the UK’s LLW. AREVA and EdF have submitted a waste characterisation documentation to enable LLWR Management Ltd. to verify the acceptability of UK EPR LLW to the LLWR. LLW will be transported to the LLWR using the ISO containers recommended by LLWR Management Ltd. 5.1.1.3 Local Landfills The acceptability of Very Low Level Waste (VLLW) to local landfill is a matter for site specific assessments which will need to be assessed once the national position regarding VLLW is finalised.
EPR UK N° NESH-G/2008/en/0123 REV. A PAGE 37 / 257 6 OPERATIONAL WASTE CHARACTERISTICS 6.1 Introduction During the operation of the UK EPR, waste streams will be generated. Liquid effluent generated during the operation of the UK EPR will be treated to generate a clean discharge. The treatment of liquid effluent will generate solid waste as a by product. For completeness this waste is included below. In this section these waste streams are documented in terms of estimated total quantities and annual arisings. The physical, chemical and radiological characterisation is presented. 6.2 Waste Characterisation Methodology The waste streams that will be generated from operation of a UK EPR have been characterised by EdF by examining the waste arisings from several operating French reactors. These are expected values and variations in their absolute accuracy does not effect the content of this strategy. 6.3 Summary of Operational Waste Arisings The UK EPR will generate operational wastes that will be classified as ILW or LLW based on beta-gamma activity only. Table 2 shows a summary of the expected waste arisings from the UK EPR. Figure 2 and Figure 3 illustrate the percentage make-up of the wastes when segregated into LLW and ILW arisings.
