The Ministry of Defence has confirmed that £340 million will be invested in infrastructure at Rosyth Dockyard to support the Dreadnought submarine programme and the dismantling of retired nuclear submarines.
The figures were set out in a written answer by Defence Minister Maria Eagle on 1 September.
Eagle stated that “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.”
She added that “the Submarine Dismantling Project (SDP) includes infrastructure works at Rosyth to enable the removal and processing of all legacy radioactive waste from dismantled submarines.”
Work has already begun under the project. “Activity at Rosyth has begun, with HMS Swiftsure being dismantled and a further six decommissioned nuclear submarines awaiting disposal,” Eagle confirmed.
She made clear that the headline figure includes the dismantling work as well as the docking facility. “The above costings include the elements of the SDP that are being undertaken at Rosyth,” her response concluded.
The Submarine Dismantling Project (SDP) was approved in 2013 to provide a long-term approach for disposing of 27 decommissioned Royal Navy nuclear submarines. The Ministry of Defence, through the Submarine Delivery Agency, oversees the programme. Defuelled submarines are held in afloat storage, with seven based at Rosyth and fifteen at Devonport. Regular checks are carried out to maintain standards of safety and security during this storage period.
HMS Swiftsure, withdrawn from service in the 1990s, is being used as the initial demonstrator for dismantling at Rosyth Dockyard. In June 2025, removal of its fin marked the first major stage in cutting into the hull. The dismantling method aims to recycle a large proportion of the vessel’s materials, including high-grade steel. Work on Swiftsure is scheduled to continue into 2026, with lessons applied to future submarines in the programme.
The project also covers the handling of radioactive material. Reactor pressure vessels are to be removed intact and placed into interim storage until a permanent Geological Disposal Facility is available, which is not expected before the 2040s. Dismantling is planned to take place at both Rosyth and Devonport, with further infrastructure and processes to be developed as additional submarines enter the programme.
The last Paragraph contains the Interesting/disapointing bit. Neraly 80 years from design to safe disposal facility is found.
*Kicking the can down the road*
The problem is that nobody wants this storage facility on their doorstep – indeed why would they?
We don’t live in a country with a large landmass(USA etc) so this is always going to be a highly contentious issue. There will be lots of fun surrounding this decision when it is eventually made.
Not really so.
A number of communities want it – mainly those with a long nuclear history.
Trouble is you can always find someone who says ‘that would be a mistake’
It is essential that we build one but I can remember this rattling around din s I was in short trousers and this is always ‘about to be solved’ the idea of this being opened by 2040s is comedy value.
Got to disagree with you here, I haven’t seen any community volunteering for this facility. Although I will admit that those whom already deal with nuclear waste are probably going to be at the forefront of where such a facility is likely to be located. Doesn’t of course follow that they are all willing to embrace the idea either.
Yes SB, I too remember this from decades back @ Upholder Class Times and the selling off of the SSK’s going all in with N Boats and still we have no answer. It’s sadder than just comical.
The Through life costs are astranomical and no Government wants to face the economical consequences.
*I told you so*
It’s got almost nothing to do with the population, Geological Disposal Facility’s are all about the correct Geology and stability, with a very big focus on stability a GDF has to consider ice ages and they are looking at containment over a hundred thousand year period. At present there are only 3 sites in the UK that are in the running, 2 in Cumbria and one in Lincolnshire. Survey wise they think it’s going to be another decade or so and building is probably 20-25 years ( this is a massive civil engineering project going to depths of 200-1000 meters down. Interestingly the first ever GDF only opened last year in Finland.
Yup, this is where the money is and no government will race to sort it.
There is an argumant that Tech Progress might just have given other options eventually rather than the N route we took. It’s an unknown cost that seems to be without limit and that money buys a lot of Tech Development over the many decades.
What do you expect this is the UK piss poor at throughlife capability which includes disposal!!
At least disposal is occurring.
Beer in mind it is another cash stream from RN’s hyper stretched budget.
I wouldn’t be shocked if there were 30 N Boats awaiting full disposal by the 40’s. there are some 20 sitting around currently. Including the R Boats.
How long is it forecasted to get rid the backlog?
I wonder if we will be able to do one per year with the two sites we have
No, Devenport won’t be done till the 2040s
I don’t believe anyone really knows and TBH, I would suspect that no one wants to put any dates or costs to it either.
The simple fact is an N Boat has staggering through life costs attached, not just Build but Maintanence, Facilities, Inspections, storage and disposal.
I would love to hear from ULYA (I shouted her name as she might not hear it) on this subject and what her fellow Countrypersons are doing with theirs.
Come on ULYA, do that magic appearance thing again🤔
