Decommissioned Nuclear-Powered Submarines

Baroness Goldie Excerpts

Wednesday 23rd October 2024 Lords Chamber

[Lord Coaker (Lab)]

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.

[Baroness Goldie (Con)]

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?

[Lord Coaker (Lab)]

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.
