  1. NuLeAF Seminar NDA Integrated Waste Management Strategy Programme update 24th October 2012

  2. Integrated Waste Management LLW ILW HLW

  3. Past Practices

  4. GDF Alternative Disposal Option(s) GDF HAW Baseline (Each site) , Interim storage Retrievals Treatment, conditioning & packaging NOT FOR SCOTTISH WASTE HAW Strategy Characterise Consider Options (..where required) Select optimised storage regime: Package & Store Sort and Segregation Opportunities • UK Solutions: • e.g. • Waste processing services • Consolidated Storage including decay storage • Site solutions: • e.g. • Treatment • Decay storage • Support to risk reduction programmes • Robust storage LLWR / Exempt

  5. Products Products A) HAW Treatment • Thermal treatment • Regional and Mobile Treatment B) HAW Storage • Long term storage guidance • Storage co-location and consolidation • Self shielding containers • HAW Disposal • Geological disposal • Other HAW disposal options (Scottish HAW Policy)

  6. Products Products D) Waste Groups • Graphite waste management • Alpha waste management E) LLW Disposal • VLLW and lower activity waste • Environmental Safety Case • Ensuring best use of LLWR into the future F) Support to other NDA Themes • Decommissioning strategies • On-site disposal • Co-location

  7. Products Products G) Revised NDA Strategy Documents • IWM Plan • NDA Strategy III • Others • Support to Scottish Government on Higher Activity Waste Strategy • Integrated Waste Strategies • Discharges: how OSPAR commitments affect our strategic decision making

  8. ILW Storage at Magnox

  9. Waste storage - Storage concepts • Thin walled package • Shielded store • Shielded package • Thin walled store

  10. Waste storage - Storage concepts RWMD Container MiniStores Container

  11. Stakeholder engagement • Project has just been initiated and involves Magnox and EdF Energy sites • The work will take into consideration other Magnox strategic programmes • Programme rather than individual task approach to Stakeholder Engagement

  12. ILW / LLW Cross-Boundary Wastes Slides courtesy of LLWR

  13. Issue ILW / LLW Cross-Boundary wastes defined as those wastes at either side of the LLW radiological classification boundary that could practicably be managed either as LLW or ILW. • Wide range of management approaches can be employed (e.g. decay storage, decontamination, encapsulation, optimised disposal etc.) • Similarly diverse range of factors used by SLCs to optioneer management approach for their wastes (e.g. cost, schedule, ALARP, environmental factors, waste characteristics, availability of waste route etc.) • SLCs have indicated that there is an absence of centralised guidance on the factors to consider when making waste management decisions for cross-boundary wastes. • LLWR led task

  14. Compilation of non-cost decision making factors Pros / Cons of management approaches Inventory Review Lifecycle cost model Decision-making logic (“toolkit”) showing relationships between factors and if / how combinations of factors drive certain decisions. OUTPUT – Position paper and recommendations on the management of waste close to LLW / ILW categorisation boundary. Elements of position paper
