Oral Answers to Questions

Baroness Clark of Kilwinning Excerpts

Monday 17th March 2014 Commons Chamber

[Dr Murrison]

My hon. Friend takes a great interest in this and will be aware of the large number of military and civilian missions that the European Union has mounted: there are 16 in all, four of which are military. My hon. Friend will be aware of the EU training mission to Mali—EUTM Mali—and EUCAP Nestor. It is very important to understand that in all of these scenarios we have to work with partners, meaning NATO first and foremost, but other partnerships where it is expedient to do so.

15. What recent progress his Department has made on its response to the internal radiation leak aboard HMS Vanguard; and if he will make a statement.

[The Secretary of State for Defence (Mr Philip Hammond)]

Let me make it clear to the hon. Lady that there has been no issue with the reactor on HMS Vanguard or, indeed, any of our submarines. I announced to the House on 6 March that there had been a small fuel element breach in the naval test reactor at Dounreay, but that did not lead to a leak of radiation from the reactor circuit.

[Katy Clark]

I thank the Secretary of State for his answer. What assessment has he made of whether the reactors on all Vanguard and Astute-class submarines will last the full lifetime of the submarines?

[Mr Hammond]

As I explained to the House when I made my statement, the purpose of the naval test reactor at Dounreay is to run the reactor hard and flat out, as it were, ahead of the operational reactors on the submarines, to see what happens as they approach the end of their planned life. The reactors on board our submarines have nothing like the percentage fuel burn that the reactor at Dounreay has now experienced, so we are looking at something that has developed at a much further advanced stage of the life of the reactor. We have, however, taken the decision, on a precautionary basis, to refuel HMS Vanguard during her planned deep-maintenance period. Once the reactor at Dounreay is decommissioned, it will be examined in detail and we will then have much greater evidence of what has caused the issue and be able to make sensible decisions about the future.
