UKRWI 2010 Background

• 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

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
