Defence: Nuclear Submarines

Debate between Lord Astor of Hever and Lord Maclennan of Rogart

Thursday 6th March 2014 Lords Chamber

[Lord Astor of Hever]

My Lords, I start by thanking the noble Lord for his support. As he said, this is a precautionary measure. Although this is not a safety issue, obviously the safety of the civilian workers and of our crews is very much in our minds. The noble Lord mentioned the events of the past few days. There is no current nuclear threat to the UK, but we can never discount the possibility that one could re-emerge in the future. I can vigorously give the noble Lord the assurance that he asked for.

[Lord Maclennan of Rogart (LD)]

My Lords, since the naval reactor test establishment has been described as being very safe and a low-risk site, and since low levels of radioactivity were detected in the cooling water surrounding the prototype core, and that was done, as I understand it, at the Dounreay site, why is it being decommissioned? There does not appear to be provision for reinstating similar testing facilities at Devonport or at the reactor plant at Raynesway in Derby, which were comparable to those that were successful in detecting this fault at Dounreay. This will have an impact on the local economy. The decommissioning will be expensive in that it has to be reconstructed elsewhere, whereas there is a team of highly skilled operators at the existing site. In the light of the non-disclosure or unawareness of what caused this fault, I do not fully understand from the Statement why such a step is being taken.

[Lord Astor of Hever]

My Lords, my noble friend asked me why it is being decommissioned and what is going to happen afterwards. I assure him that this has been very carefully thought out. I asked this question earlier of the people who briefed me. The answer is very technical and sensitive, and it may be better if I write to my noble friend. The short answer is that there has been so much technical progress that people can learn in much quicker and better ways than in the way things were done at Dounreay, but I am happy to write to my noble friend because it is a very important question.
