Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what estimate his Department has made of the cost of infrastructure improvement works at HMNB Devonport; and whether those works involve the (a) removal, (b) containment and (c) replacement of equipment identified as radioactively contaminated.

The current estimate for the costs of infrastructure improvement works at Devonport including the Naval Base and Dockyard are £5 billion. This important activity, which includes works at HMNB Devonport and investment in Devonport Dockyard, will support the Royal Navy’s military outputs for decades to come.

These works include areas of the Nuclear Authorised and Licensed Sites at Devonport and will include the removal, upgrade and replacement of equipment/systems which have been identified as radioactive.
