Managing Risk Reduction at Sellafield: Nuclear Decommissioning Authority
The Stationery Office, Nov 7, 2012 - Political Science - 48 pages
A report today by the National Audit Office highlights the considerable challenge faced by the Nuclear Decommissioning Authority in taking forward the clean-up of Sellafield, the UK's largest and most hazardous nuclear site. To date the performance of some of the major projects at Sellafield has been poor. The Authority inherited a legacy of poor planning and neglect over several decades when it took ownership of Sellafield in April 2005. The Authority achieved an important milestone in May 2011 when it approved a more robust lifetime plan for the clean-up of Sellafield site by 2120. The improved lifetime plan contributed to an increase in the Authority's provision for decommissioning the site to £67 billion (undiscounted) as at March 2012, up from £47 billion as at March 2009. Significant uncertainties and scheduling risks remain, which the authority is working to understand and address. For example, there is considerable uncertainty over the time required and cost of completing facilities to treat and store highly radioactive material held in deteriorating legacy ponds and silos. Today's report concluded that it is too early to judge whether the appointment of Nuclear Management Partners Limited as the parent body of Sellafield is delivering value for money.
