My Lords, I am very grateful to noble Lords who have spoken, particularly to the noble Lord, Lord Broers, who instigated this valuable debate, and to the committee for its work and recommendations. We have covered a number of key areas, and I hope I cover some of the questions raised, if not all of them, in my remarks.

We all recognise that radioactive waste management is complex and probably not the most exciting area in the world. However, it is a very complex and important subject, particularly as we move into the arena of new nuclear, which has not happened for 27 years. I do not want to underplay the fact that we have given the green light for new nuclear where nothing has happened in the past. This is a very big strategic decision, and I am glad it finds favour on all sides of the House. In the past, I have complimented the contribution by the now opposition Benches in changing public attitudes towards new nuclear when they were in government. That gave us a springboard, but we acted upon it, and it is important that that is taken on board. I also want to make it clear that the Government take these issues with great responsibility. Ultimately, we will make the decisions. We welcome reports and advice, and we are very open to them, but ultimately we will decide how to manage radioactive waste safely and fairly using the available evidence and analysis and the contributions that we get from all sides of the House.

The NDA is the UK's competent body responsible for that, particularly in respect of nuclear waste. The NDA reports to government. I compliment the previous Government, who sorted out a serious problem in the management of the NDA. I believe that the NDA is now a well run organisation. We in government have a great deal of confidence in it. It reports to me personally, I have an excellent working relationship with it, and I want to pay compliment to the work it is doing. As a Government and as Members of this House, we must trust and empower it to operate and act in this extremely difficult area.

I shall refer to the progress we have made on geological disposal. As all noble Lords have said, this is a timeline that most of us cannot associate with. I may be around in 2040; some noble Lords may not be. I am keeping my fingers crossed that I will be. The noble Lord is quite right that, if we look backwards, 1890-when some of the noble Lords opposite were born-seems like an awful long time ago. The noble Lord, Lord Hunt, knows what I am talking about, I think. It is a timeline that is very difficult to associate with and a timeline that we have to improve. It would be irresponsible if we did not. However, it is not entirely dependent on us. It is set by the co-operation of the people of Cumbria, who are critical to this process. Since we have been in Government, we have published an indicative timeline for implementation. As I have said, that is not enough. We want to reduce it. We have agreed to produce an annual report to Parliament on progress and we are committed to improving the timeline, which noble Lords will see as we progress. We have established the Geological Disposal Implementation Board chaired by my colleague the Minister of State for Energy, Charles Hendry, to enhance accountability for delivery.

We have carried out and have published the initial geological screening of the volunteer area in West Cumbria. We have supported the second round of the West Cumbrian MRWS Partnership's formal public and stakeholder engagement programme and have agreed a strong funding settlement for NDA in the latest spending round to enable it to make progress in this area. However, it is much more important that we send messages to the people of Cumbria that Cumbria can become a nuclear place of excellence. We have indicated that it can be the site for a new nuclear power station.

I shall come to the Mox plant later, but the hopeful signs of such a plant, which have been sitting in the wings for years, will give good encouragement to the community. I hope that the community will feel that we are supporting them and establishing them as a centre of excellence, and that they will respond by supporting us in the geological storage timelines.

On Mox, on Monday, I launched the consultation on the management options for the UK plutonium stocks. We have the largest plutonium stocks in the world, as the noble Lord, Lord O'Neill of Clackmannan, has rightly said. I think we agree that it is time to get to grips with this issue and to develop a coherent, strategic and comprehensive plan for the future. There is no point in having this enormous amount of waste sitting there when we can turn it, we hope, into revenue or less cost. That is what the consultation will look at.

I have done some cost evaluations with the NDA. We have sought advice from a number of the experts in this field in reviewing it. Through this consultation process, we should be able to deliver clear signals, which is our ambition. But if at the end of the day that ambition cannot be met with reality of cost, of course we will not do it. As I mentioned earlier, it sends clear signals to Sellafield and the people of Cumbria that we are very committed to that part of the world.

The noble Lord, Lord Broers, and other noble Lords rightly mentioned the importance of high hazard. I was deeply concerned when I visited the high hazard sites and saw the lack of progress. As a result, the first thing I did in the spending review was to negotiate with the Treasury, in very difficult times, an increase in spending for the NDA so that we could tackle and confront these issues head on. We have reduced by two years the timescale of dealing with the emptying of silos. We should have completion of that by 2016 to 2018. This fundamental increase in timescale needs to be carried out because it is in the national interest. We are putting real energy and significance into this. The NDA is under no illusions that this is the main priority of this Government.
