Despite EDFE extending the operating lives of all the AGR stations, its financial contributions … Read more

Government response AI summary
The department agrees that the terms of the 2009 sale of the nuclear stations agreed by the Department with EDFE placed a disproportionate amount of risk for meeting future decommissioning costs on the taxpayer and refers to their response to recommendation 3.

28 Conclusion Third Report - The future of the Advanc… Acknowledged

The AGR decommissioning programme is complex, and key organisations already have substantial portfolios of work.

The AGR decommissioning programme is complex, and key organisations already have substantial portfolios of work. The NDA, for instance, already has a very heavy workload decommissioning the Magnox fleet and parts of the Sellafield site to which the AGRs will now be added. The NDA’s subsidiary, Magnox Ltd, is currently … Read more

Government response AI summary
The department agrees that arrangements for transferring nuclear stations to NDA are worryingly under-developed, and there is a risk that transfer negotiations between EDFE and NDA could drag on and increase the costs to the taxpayer and refers to the response to recommendation 6.

The Department told us that following its experience of the Magnox contract, it had undertaken a full review to establish whether it had the right governance and it was now confident that this was the case. It also told us that the NDA has similarly taken “really important steps in … Read more

Decommissioning the AGR stations is an unusual programme compared with others in government as no single organisation has complete responsibility and authority for performance overall. The success of the programme will depend significantly on the ability of the Department, NDA and EDFE to work together effectively and resolve any problems … Read more

Given the centrality of its role we asked the Department whether its own role was subject to sufficient scrutiny and whether AGR decommissioning should be included in the Government Major Projects Portfolio. The Department told us that similar concerns had been raised by HM Treasury and Cabinet Office. However, the … Read more
