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 preliminary plans for infrastructure upgrades at Rosyth Dockyard have been approved and industry have been engaged to begin progressing the scheme design. Once the scheme design is complete final costs for the project will be negotiated. The work will include the requirement to deliver a contingent docking facility for HMS DREADNOUGHT during its sea trial period, at Rosyth Dockyard.

The Submarine Dismantling Project (SDP) includes infrastructure works at Rosyth, where final costs for the project are still being negotiated, 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.
