  1. NuLEAF SeminarDeveloping the Evidence Base – LLW arisings and the need for management facilities 22nd March 2011 Mervin McMinn – National Waste Inventory Manager, NDA David Rossiter – Head of National Strategy Implementation, LLWR Ltd

  2. UK Radioactive Waste Inventory Mervin McMinn National Waste Inventory Manager, NDA

  3. UKRWI is the UK’s reference dataset on radioactive waste Updated usually on a 3 yearly cycle NDA currently manage the process on behalf of DECC Information collated from UK’s major radioactive waste producers existing stocks, and forecast arisings 2010 UKRWI, stock date 1 April 2010, published today UKRWI 2010 Background

  4. Inventory Outputs Information on website Suite of reports

  5. Total Volumes

  6. Changes since 2007 inventory

  7. Analysis of LLW Volumes David Rossiter Head of National Strategy Implementation, LLWR Ltd

  8. LLW Strategic Review 2008 LLW Strategic Review was a critical milestone for NDA & LLWR Underpinned LLW baseline established Opportunities identified for several £billion savings Key Baseline Components: LLW Management Strategies LLW Inventory (RWI 2007 and 2008 WATs for NDA sites = WIDRAM 2008) Costs and liabilities associated with LLW management Assets and infrastructure (existing and planned) Informed development of the LLW Strategy Strategic Review currently being updated to include RWI 2010 inventory

  9. Trends in Radioactive Waste Inventories since 1994

  10. Cumulative Forecast Raw Arisings of UK LLW and VLLW Total: 4.4 million m³ VLLW: 3.3 million m³ LLW: 1.1 million m³

  11. Annual Raw Arisings of UK LLW and VLLW

  12. Near-term Regional Distribution of Raw LLW and VLLW (2010 - 2020)

  13. Lifetime UK Regional Distribution of Raw LLW and VLLW (2010 - 2120)

  14. What is LLW?

  15. Material Proportions in Raw LLW arisings LLW: 1.1 million m³

  16. Material Proportions in Raw VLLW arisings VLLW: 3.3 million m³

  17. Current Facilities: 1 LLW national disposal site (LLWR) 1 Onsite LLW/VLLW disposal site 1 Commercial LLW/VLLW disposal site 3 Metal recycling (Grit-blasting) 10 Incinerators 3 Supercompactors Commercial Overseas Facilities: 4 Metal recycling (Melting) 3 Incinerators/thermal treatment Potential Facilities: 1 Onsite LLW/VLLW disposal site (Dounreay) 3 Commercial LLW/VLLW disposal sites (all awaiting auth.) Geographical Location of LLW Facilities

  18. Activity Distribution of Historic Vault Disposals (2005-2010) Total: 2,561 containers (50,000m3) ~65% Less than 200Bq/g ~5% at HV VLLW activity

  19. Work ongoing to refine LLW inventory estimates 1. Magnox SMART inventory reviews 2. Sellafield decommissioning mandate surveys Likely to be exempt VLLW LLW

  20. Potentially Contaminated Land Currently not in the LLW Inventory Total potential volume: 13.2 Million m3 Still large uncertainty in these volumes Work ongoing to revise inventory estimates NDA Land Quality Management Strategy under development Key interfaces with LLW strategy

  21. Summary 2010 UKRWI, stock date 1 April 2010, published today Total LLW – 1.1million m3 (0.3million m3 in next 10 years) Total VLLW – 3.3million m3 (0.2million m3 in next 10 years) Full LLW inventory analysis available in LLW Strategic Review to be published Spring 2011 LLWR continue to work with waste producers to improve the accuracy of estimates More information: www.llwrsite.com/llw-strategy
