Devonport Dockyard nuclear sub dismantling will be hit by delays, new report predicts

Nuclear Information Service expects no quick fix for removal of 15 decommissioned submarines laid up at Devonport

William Telford, Business Editor, 15 Feb 24 Plymouth Live

The dismantling of 15 decommissioned nuclear subs at Devonport Royal Dockyard is likely to hit delays, according to a new report. The briefing document published by the independent Nuclear Information Service says a history of infrastructure work at the Plymouth facility means “delays are more likely to materialise than not”.

The report said upgrades to 14 and 15 Docks and the Submarine Refit Complex at Devonport are overdue and progress on submarine dismantling is “on hold” while the Government focuses on its £298m “demonstrator” project to fully dismantle HMS Swiftsure at Rosyth, forecast to be complete at the end of 2026.

The Ministry of Defence told Plymouth Live it aims to dismantle the nuclear submarines at Devonport “as soon as practicably possible”. It said the Swiftsure project will “inform and refine” the dismantling process for subsequent submarines and provide more certainty on the dismantling schedule for future submarines and remains on schedule for completion by the original target date of 2026.

The Nuclear Information Service’s briefing report on Devonport Royal Dockyard gives an overview of the facility and its role in servicing the UK’s submarine fleet, including its nuclear-armed submarines. The report said: “The 15 out-of-service nuclear submarines stored at Devonport, and a further seven that are at Rosyth, together comprise every nuclear submarine the Navy has ever fielded.

“Aside from the long-overdue upgrades to 14 and 15 Docks, and the Submarine Refit Complex, progress on submarine dismantling is on hold while the Government focuses on its ‘demonstrator’ project to fully dismantle HMS Swiftsure. This work is being undertaken at Rosyth and is currently forecast to be complete at the end of 2026 at a cost of £298m.

“Three more submarines at Rosyth have had low-level waste removed from them, but it is not clear if work to defuel the nine submarines at Devonport that are still carrying nuclear fuel will begin before completion of the demonstrator project.

In 2016 the MoD estimated that fully dismantling 27 submarines would cost £2.4bn. Although the risk to in-service submarine availability from delays to submarine dismantling and defuelling is lower than from delays to the maintenance schedule, the history of problems with the project and with infrastructure work at Devonport suggests that delays are more likely to materialise than not.”…………………………..more  https://www.plymouthherald.co.uk/news/plymouth-news/devonport-dockyard-nuclear-sub-dismantling-9098888—
