2. LA LLW Arisings and Capacity Analysis Nuleaf Radioactive Waste Planning Seminar 12 th March 2013 David Rossiter Head of National Programme LLW Repository Ltd

3. The Broader Capacity Challenge UK 2010 National Inventory forecast 4.4 million m 3 of raw LLW Packaging increases volume by factor of 1.5 to 6.4 million m 3 (if disposed to LLWR) Maximum vault capacity of LLWR is 1.7 million m 3 Repository can last until 2130 – but only if we manage the space wisely: –Recycling & volume reduction –Alternative solutions for LA LLW & VLLW

4. 08/03/2011 3 Low Activity Low Level Waste and Very Low Level Waste from nuclear decommissioning and site restoration

5. 08/03/2011 4 Highly Engineered Vaults at LLWR

6. Key workstreams: Consulted through LA LLW Working Group 1.Arisings vs. Capacity analysis 2.Sellafield onsite disposal feasibility 3.Assessment of onsite disposal at other NDA sites 4.Assessment of use of LLW in the LLWR cap 5.Criteria for de-licensing of nuclear sites 6.CIRIA coastal erosion of landfills Project 1.Arisings vs. Capacity analysis 2.Sellafield onsite disposal feasibility 3.Assessment of onsite disposal at other NDA sites 4.Assessment of use of LLW in the LLWR cap 5.Criteria for de-licensing of nuclear sites 6.CIRIA coastal erosion of landfills Project 5 Developing a position on LA LLW/VLLW Informs NDA position on LA LLW Management

7. Current UK Facilities: –Augean*Kings Cliffe(National) –FCC*Lillyhall(National) –SITA *Clifton Marsh(National) –Sellafield CLESA (Onsite only) * LLWR VLLW framework service provides all waste producers with access to these facilities Potential Future UK Facilities: –DSRLDounreay (Onsite only) –SITAKeekle Head(National) –LLWR Reuse in Cap(TBC) –Sellafield Future landfill(TBC) VLLW / LA LLW Disposal Options

8. Approach National inventory forecasts for LA LLW and VLLW reviewed: –UKRWI 2010 (All sites) –2012 Waste Inventory Forms (NDA only) –2012 Joint Management Plans (NDA only) Capacity of existing sites assessed for the period 2012 – 2030 on both a national and regional basis Dounreay and CLESA wastes excluded (as onsite only) Consult results with VLLW Working Group and supply chain (ongoing)

9. National LA LLW Arisings (ex. CLESA & Dounreay) 2012 short-term forecasts are lower than 2010

10. Comparison of LA LLW arisings vs capacity to 2016 (ex. CLESA & Dounreay)

11. Conclusions Comparing capacity and arisings is not always straightforward! There is uncertainty in the inventory volumes There is adequate capacity in the existing Permitted sites until December 2016 There will be adequate capacity until around 2026-2030 if planning consents are extended There is adequate capacity in both northern and southern regions Analysis does not consider other potential users of these facilities (e.g. non-nuclear, NORM, etc) There is a need to improve accuracy of the inventory data with respect to volumes and classification Aiming to finalise and publish report in March 2013
