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
