Nuclear Power Stations: Decommissioning

Volume 472: debated on Wednesday 20 February 2008

To ask the Secretary of State for Business, Enterprise and Regulatory Reform what discussions he has had with the Chairman of the Nuclear Decommissioning Authority (NDA) on engaging professional cost advisers to review cost estimates provided to the NDA by its site licencees. (184895)

My Department has regular discussions with the Chairman of the Nuclear Decommissioning Authority (NDA) on a range of issues, including the measurement of the size of the task facing the NDA. The estimation of the lifetime costs of the NDA’s mission is a key task for the NDA, and it therefore has processes in place for testing and challenging the estimates, including using advisers where appropriate to help them evaluate both the process and to review the cost estimates provided to the NDA by its site licensees.

To ask the Secretary of State for Business, Enterprise and Regulatory Reform what estimate he has made of the costs of decommissioning and decontaminating nuclear power stations over the next (a) 10 and (b) 20 years. (185788)

[holding answer 18 February 2008]: Estimating the costs of decommissioning and cleaning up the historic civil public nuclear sites, including the Magnox nuclear power stations, is the responsibility of the Nuclear Decommissioning Authority (NDA). The latest estimate is set out in the NDA’s annual report and accounts 2006-07, which is available on the NDA’s website at:

www.nda.gov.uk.

The NDA’s latest estimates of the cost of decommissioning and clean-up of the 10 Magnox stations in discounted 2007 money values are as follows:

£4.8 billion for the first 10 years (2007 to 2016 inclusive) for the decommissioning and clean-up of all ten Magnox stations.

£0.6 billion for the second ten years (2017 to 2026 inclusive) for the decommissioning and clean-up of all 10 Magnox stations.
