  1. Assessment of Spent Fuel Management Options in the UK Generic Design Assessment Process Chris Fisher Health and Safety Executive

  2. New nuclear power stations Our approach

  3. Regulating a new nuclear build Regulators must consider 3 key elements: reactor design site operating organisation

  4. Improving our approach Being more efficient and effective Getting involved early Adopting a staged approach Regulators working together Taking account of international ‘harmonised designs’ Drawing on the work of overseas regulators Improving our openness and transparency

  5. New two phase regulatory process PHASE 1 : Generic Design Assessment (GDA) Assess safety case for reactor design NII, EA & OCNS working in close cooperation generic site “characteristics” PHASE 2 : Site licensing and permitting site specific operator specific using already assessed designs Two phases may overlap

  6. GDA – progress Assessments started – August 2007 Initial assessments completed - March 2008 Detailed assessment of the remaining designs started - 12 June 2008 Step 3 reports published – November 2009 EA Public consultation – Summer 2010 Target for GDA reporting – June 2011

  7. Now Site specific Phase 1 GDA Timeline Detailed design assessment Clearance of GDA Caveats Step 3 Level of scrutiny Overall design safety review Step 4 Step 2 Phase 2 Licensing assessment Fundamental overview Step 1 Preparation June 2011 Dec 2012 Nov 2009 May 2007 Aug 2007 Mar 2008

  8. GDA Designs

  9. Spent Fuel Assessment

  10. UK policy • “once through fuel cycle”; • “higher activity wastes” will comprise of spent fuel and ILW; • “interim storage until a geological disposal facility can receive waste”. (Department of Energy and Climate Change, Draft National Policy Statement for Nuclear Power Generation (EN-6), November 2009)

  11. Our aims Requesting Parties to identify: • types of facility; • when to construct facilities; • research to ensure spent fuel can be safely managed, transported and disposed of. (http://www.hse.gov.uk/newreactors/wasteplants.pdf)

  12. Timescales

  13. Timescales Period depends on the availability of a GDF

  14. The implementing organisation for the geological disposal facility for higher activity wastes NDA Radioactive Waste Management Directorate (RWMD)

  15. RWMD Assessment • The higher activity wastes from new build reactors are broadly similar to other wastes held by the UK • Spent fuel may require cooling for up to 100 years before disposal

  16. Research needs • Can RWMD bring forward the time when they would accept spent fuel? • Can fuel be safely stored for 100 years and then be recovered and transported? • Can facility lifetimes be substantiated?
