Question

To ask the Secretary of State for Energy and Climate Change, with reference to the Nuclear Decommissioning Authority's Annual Report and Accounts for 2013-14, published on 23 June 2014, what assessment he has made of the implications for his policy on the evaluation of proposals for funded radioactive waste and decommissioning plans presented to him by private nuclear operators of the recent increase in the cost of dealing with legacy radioactive waste and decommissioning announced in that report.

Recent changes in the estimated costs of dealing with legacy radioactive waste and decommissioning announced in the Nuclear Decommissioning Authority's Annual Report and Accounts for 2013/14 are due in their entirety to the decommissioning programme at Sellafield. These costs should not be used as a guide to costs of decommissioning modern nuclear reactor sites. The vast majority of the liability at Sellafield is a result of the Cold War military programme on that site, dating back to the 1940s, and the very early days of the civil nuclear industry, dating back to the 1950s and 1960s. These historic facilities were built extremely rapidly to very different quality and safety standards compared with nuclear plants constructed today and without plans for how they would be ultimately decommissioned, These facilities present a unique decommissioning challenge requiring a complex suite of engineering projects in order to first gain access to their waste inventory before retrieving and then treating this material ready for long-term disposal. The activity required to decommission these facilities at Sellafield bears no relation to the work required to decommission modern nuclear facilities. Operators of nuclear power stations being constructed under the Government's new build programme are required to publish plans detailing how these facilities will be decommissioned and the operators themselves are liable for the costs associated with this decommissioning work.
