Waste is our Product! Developing, Implementing and Optimising Waste Management at Dounreay - 19039

摘要

The UK's Fast Breeder Reactor Research programme was centred at Dounreay, in the very north of Scotland, from 1955. Since 1994, the site has been focused on decommissioning, and represents one of the most complex, technically challenging and hazardous nuclear clean-up projects in Europe. Since 2012, Dounreay Site Restoration Ltd (DSRL) has been contracted by the NDA as the Site License Company to deliver the defined scope of work, under a Target Cost contract, to decommission the site to achieve the Interim End State by 2030-2033, whilst managing the transition of its people. All parties, including DSRL's Parent Body. Organisation Cavendish Dounreay Partnership Ltd (a consortium of Cavendish Nuclear, AECOM, & Jacobs), recognise that there are significant technical and regulatory challenges to achieve this, as well as safely managing the transition for our workforce on what is effectively a "closure" contract. The product of decommissioning is waste; over the course of the programme, a full range of higher activity and lower level radioactive wastes will be generated, and must be safely managed. This paper will address: · The Policy issues relating to radioactive waste management at Dounreay, including particular issues relating to implementation of Scottish policy, including how Waste Management is Optimised. · An overview of the decommissioning programme and the delivery of an Interim End State · The type, range and nature of radioactive wastes requiring safe management at Dounreay · Higher Activity Wastes (HAW): · Setting higher activity waste strategy; defining products and interim storage requirements · Technical, regulatory and stakeholder issues for HAW strategy · Lower Activity Wastes: · Setting Low Level Waste (LLW) strategy; defining a disposal product and development and status for Dounreay's LLW Disposal Vaults · Implementing LLW strategy · Technical, regulatory and stakeholder issues for LLW strategy · Optimising Waste Management -Optimising waste from generation (from decommissioning workfaces) through to disposal -why, and how! · The Waste Informed Decommissioning model as a methodology and approach · Impact and importance of Waste Management on a target cost contract · Establishment of a Waste Optimisation Programme to drive ownership, delivery and culture change · Management responsibilities and informing organisational design · Sharing and learning from Best Practice · The Challenge - how to ensure workforce and teams are engaged in delivering optimisation requirements · Conclusions
