I am grateful to the noble Lord, Lord O'Neill of Clackmannan, for pulling me up on that point. He is right that a centre of excellence exists. There is no question about what he has just said. The most important point is that we continue to have Cumbria as a centre of excellence and that in times of recession that is put beyond doubt for the people who live there.

CoRWM has provided three formal reports to government since 2008, alongside numerous position papers and regular informal advice. The three formal reports cover the government policy areas of geological disposal, interim storage and associated R&D. I accept the important point that the papers should be clearly marked, placed and presented. CoRWM now explains the nature of its papers, but I take on board the point that was made.

We have responded to the reports and are committed to responding to all CoRWM's substantive advice. We look forward to further discussions with it and to receiving ongoing advice, as we do from all experts in this area, particularly the committee.

I turn to the committee's recommendations. We believe that there should be the right mix of personnel, as the noble Lords, Lord Broers and Lord O'Neill of Clackmannan, rightly mentioned. Over time, the precise skill set required may vary. We need to ensure that CoRWM changes correspondingly to confront the various issues arising out of contemporary nuclear needs. Currently, the committee is split between two-year and four-year appointments. We will look to refresh the membership in time for the current two-year terms ending in 2012. The committee may also co-opt additional expertise to support its examination of specific topics and utilise other appropriate means of securing expert input, such as sponsored meetings or seminars.

I return to R&D, which is of fundamental importance and again touches on the matter of a centre of excellence. We have instructed the NDA to reconstitute the R&D board and to co-ordinate an R&D strategy. I say in answer to the noble Lord, Lord Grantchester, that we will look at its recommendations extremely favourably, as we have done so far by increasing our financial support for it.

The noble Lord, Lord Teverson, referred to fusion. As he well knows-he asks me this as a trick question- that is not a subject for my department. I would be happy to go at length into the subject of fusion, but as he is closely associated with BIS, I can with great confidence expect him to discuss it with that department.

The noble Lord, Lord Grantchester, drew my attention to a point that I had made on the subject of nuclear security. We are undertaking a significant review. I thank previous Ministers, including the noble Lord, Lord Hunt of Kings Heath, who kindly gave me advice on the subject. He indicated that we should consider a review of the current and future security of nuclear sites, because the issue is ongoing and we must make sure that they are fit for purpose. I am undertaking that review at the moment. It is throwing up a lot of interesting subjects and we will report on it in the near future. I assure the House that this is a high-priority item for us, and that I will be happy to keep noble Lords involved in any decisions.

In summary, I hope that noble Lords, and in particular the noble Lord, Lord Broers, do not think that we are sitting back and accepting airy-fairy timescales, or that we are not committed to doing things. We have increased the spend on solving our waste problems; we are attacking the incredibly long-term geological timescale for dealing with waste; we are looking at how we can make the best of our plutonium stock and turn it into an asset; and we are taking very seriously the high-hazard problems that we have encountered. I commend my fellow Ministers and officials for the great amount of work that they are doing. I also thank the committee and all those involved in the subject for the great advice that they give us. We have an open-door policy and welcome advice and support. This is not something that can happen today or next year; it is a 10-year programme that transcends governments, and all of us must work together with great energy and commitment.
