Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what estimate he has made of the cost of planned infrastructure upgrades at Rosyth Dockyard; whether those upgrades include the (a) removal and (b) treatment of legacy radioactive materials; and how many redundant nuclear-powered submarines are docked at that facility.

The cost of planned infrastructure upgrades at Rosyth Dockyard are £340 million. The cost includes the requirement to deliver a contingent docking facility for HMS DREADNOUGHT during its sea trial period.

The Submarine Dismantling Project (SDP) includes infrastructure works at Rosyth to enable the removal and processing of all legacy radioactive waste from dismantled submarines. Activity at Rosyth has begun, with HMS Swiftsure being dismantled and a further six decommissioned nuclear submarines awaiting disposal. The above costings include the elements of the SDP that are being undertaken at Rosyth.
