1.6 We have produced two reports on progress with nuclear decommissioning at Sellafield. The first, published in November 2012, examined how the Authority manages risk at Sellafield, focusing on performance on the largest projects.2 The second, published in October 2013 was in response to a recommendation by the Committee of Public Accounts (the Committee), and examined how the Authority gains assurance about the level of reported efficiency savings.3 The Committee has also published two reports, in February 2013 and in February 2014, when it reported on progress on the site and the Authority's decision to continue the agreement with Nuclear Management Partners into a second term.4,5
1.7 This update explains developments in the management of the site at the end of the current Parliament. The update presents data the Authority published, or that it gave to us, and summarises the Authority's documents and explanations of progress. We have checked the consistency of the data to sources, where possible, but we have not audited the Authority's underlying records. The update addresses:
• progress on the Sellafield site and its major programmes and projects and Sellafield Limited's capability and capacity (Part Two); and
• the Authority's review of the delivery model, and its plans for transition to a new model (Part Three).
