4. LLWR Ltd Key Initiatives – LTP 2008 • Provide assured storage and disposal at LLWR • Strategic partnership with NDA and consignors to develop a UK National LLW Strategy. • Transform LLWR into a fully integrated waste management operation • Open additional fit-for-purpose waste management and disposal routes • Enhanced consignor support organisation • Energise the Supply Chain

5. Commenced in September 2008: Excavation nearing completion Concrete and Bentonite batching plants established Currently constructing west side retaining wall Piling operations to the east side Area available for operation in April 2009 Completed by December 2009 Gives 10 year capacity Storage area for Segregated Wastes Vault 9

6. Vault 9 Vault 8 UK National LLW Repository capacity – March 2009

7. Environmental Safety Case • Background: • 2002 ESC not accepted by EA • 2006 Authorisation only allows storage once Vault 8 full • Revised ESC required by EA 1st May 2011 • EA unhappy with progress • Progress: • ESC work programme completely replanned Summer 2008 • New project manager and team in place • Liaising closely with EA to ensure 2011 ESC will meet their requirements • Recent interim submissions to EA have been accepted as meeting their requirements

8. UK LLW Policy – The need for change • In March 2007 the UK government published a new policy for the Management of Solid Radioactive Low Level Waste (LLW). • Recognising that the previous policy published in 1995, known as Command 2919 (Cm2919), was not written with the NDA’s large-scale decommissioning programme in mind, the new policy introduced a more flexible and fit-for-purpose approach for LLW management centred around the application of the waste hierarchy. • The policy requires the NDA to publish a UK LLW Strategy and Management Plan for integrated LLW management throughout the UK 8

10. LLW Strategic Review – Components of Baseline • LLW Management Strategies • LLWR Site Operational Strategy • Consignor site LLW management strategies • LLW Inventory • Assets and infrastructure (existing and planned) for LLW management • Costs and liabilities associated with LLW management

11. LLW Liability by SLC

12. Strategic Review Conclusions • Consignor’s LTP 2008 includes funding for implementing the hierarchy. • LLWR Ltd. LTP 2008 is based on “immediate” and “maximum” implementation of the hierarchy by all consignors. • Not all consignors have planned for “immediate” and “maximum” implementation. • The Business Case will support the process of determining the optimal level of implementation.

13. Lifecycle Cost - LLWR 1 & 2 (Business as usual) Uncontracted Liability ~ £3Bn Provision within LTP08 - £2.7Bn
