To ask His Majesty’s Government how many decommissioned nuclear-powered submarines there are in Scotland; and how many years it will take to safely dismantle them.
My Lords, there are seven decommissioned and defueled nuclear power submarines in Rosyth Royal Dockyard, Scotland. “Swiftsure”, the first vessel being disposed of, is being used as a demonstrator to refine the dismantling process under the Ministry of Defence’s submarine dismantling project. Learning from “Swiftsure” will provide more certainty about the schedule for dismantling the remaining decommissioned Royal Navy submarines. The full dismantling of “Swiftsure” is due to be complete in 2026, achieving the commitment given to the Public Accounts Committee in 2019.

I thank the Minister for his Answer. My Question happily coincided with information that was released last week, but there remains real concern that not one of these submarines has yet been dismantled. Bearing in mind that one Dreadnought submarine in Rosyth has been out of service since 1980, it will take decades to dismantle the boats remaining in both Scotland and Devonport. Can the Minister say whether there has been any progress in finding a site for the radioactive waste disposal facility which will be essential to progressing this work?
On all the things that my noble friend mentions there is progress and ongoing discussions, including the waste disposal site, but we are trying to speed up the submarine dismantling programme. Seven submarines at Rosyth are decommissioned. All have been defueled. “Swiftsure” is now in dry dock. That will be fully dismantled by the end of 2026. There are 15 such submarines at Devonport. Four of those have been defueled. However, my noble friend is quite right; we need to speed up the process and we are certainly looking at every way in which we can do that.
The noble Lord is right to ask about dismantling. As I said to my noble friend, we are seeking to speed up that process. On the new submarines, if he is referring to the Astute class submarines, seven were ordered, six are already in the water and one is now under construction in Barrow. If he means the successor to the Vanguard class, we expect the first to be in service in the early 2030s. We are making considerable progress, and I hope that answers his question.
My Lords, as the noble Baroness’s follow-up question pointed out, there is an accumulation of nuclear submarines that have been decommissioned but are still in Rosyth or Devonport. Are His Majesty’s Government sure that they are safe? Can the Minister commit to ensuring that freedom of information requests are responded to? Apparently, the MoD has not been responding to safety questions.
On freedom of information requests, if the noble Baroness has any examples that she would like me to look into, she only has to ask and I will certainly do so. Freedom of information requests should be responded to within the timeframe laid down, so I will look at that. As I said, we are looking to accelerate the dismantling programme. I am confident that the processes that we are seeking to put in place will speed that up and that they are safe.
My Lords, the noble Baroness, Lady Bryan, mentioned the disposal of nuclear material as and when it is eventually removed from the submarines. Can the Minister confirm, perhaps by letter, whether the establishment of a new disposal site—which has been debated for many years and is still no nearer, as far I can tell—will require primary legislation to be enacted? If not, how would the planning process be developed for the future disposal of that nuclear material?
I may need to write to the noble Lord. I usually like to be able to respond directly to questions, but I do not want to get the planning process wrong or give the wrong answer on whether primary or secondary legislation is needed. I will respond to him with a letter to make sure that I am accurate and will place a copy in the Library so that it is available to all noble Lords.
My Lords, on 20 May 2021, the Conservative Government published an update on the submarine dismantling project, stating that 90% of the decommissioned submarine materials could be recycled. Is the Minister in a position to confirm that his Government are committed to retaining that target? On the experience of decommissioning HMS “Swiftsure”, which is very well advanced, can he also indicate whether there is any proposal to secure an engineering impact assessment to understand how the process for future submarines might be expedited?
I pay tribute to the work that the noble Baroness did to try to speed up some of these processes. She asked two very pertinent questions. For “Swiftsure”, we retained the 90% recycling target. She will know that once a decommissioned submarine such as “Swiftsure” is defueled, there is an initial phase that takes the nuclear material out. Then there is an intermediate phase, which is followed by dry-docking—which is where “Swiftsure” is—for the rest of the submarine to be recycled. We expect 90% of that to be recycled. The whole point of “Swiftsure” is that it acts as a demonstrator project so that we can learn from how that was done—what worked and what perhaps could have been improved—and then apply that to all the other submarines that have been decommissioned.
Does the Minister recall the late, great Sir John Houghton, who identified the dangers of global warming several decades ago? As an eminent scientist, he identified the potential to generate electricity by reworking some of the nuclear waste that comes from not only submarines but other parts of the Armed Forces. Are the Government investigating that aspect?
No, we are not investigating that for nuclear submarines. The MoD takes climate change very seriously, and I have recently signed off a submission about fuel and its better economic use with respect to climate change. Right across the MoD, climate change is taken seriously, but on the noble Lord’s specific question about decommissioning nuclear submarines, there is no intention to use them, for example, to go into the grid.
