The Ministry of Defence (MoD) has announced that public exhibitions are to be held next month (December) and in January on proposals which could see scrap from the radioactive power plants in the Royal Navy’s decommissioned nuclear subs finding its way to Cheshire West and Chester.
Capenhurst based Capenhurst Nuclear Services (CNS) has already welcomed a previous MoD statement it has been shortlisted to be involved in the work, connected with the dismantling of 27 British nuclear subs once they have left naval service and have been defuelled.
These include 12 subs currently stored afloat at Devonport, Plymouth, the largest naval base in western Europe and seven at Rosyth in Scotland as well as eight subs that are still in service.
If selected, CNS would handle the safe storage of reactor pressure vessels removed from the subs.
These are radioactive due to their previous proximity to the subs’ nuclear reactors.
The intention would be the contaminated materials would eventually be moved to underground storage when this becomes available at a location to be decided some time after 2040.
The MoD says the overall project involves recycling the bulk of the subs and safely disposing of the remainder including storing the intermediate radioactive scrap from the vicinity of the reactors.
The interim storage at Capenhurst involving, if approved, a secure building, would be designed for at least 100 years’ use to provide for uncertainties.
Capenhurst was originally shortlisted on a provisional basis in February following an assessment of all the licensed nuclear sites in the country along with the Atomic Weapons Establishment sites at Aldermaston and Burghfield in Berkshire, Sellafield in west Cumbria and Chapelcross in Dumfriesshire.
David Slater, managing director of CNS, said: “This announcement is testament to the nuclear experience and expertise we have here at CNS.
“We will continue to work closely with the MoD throughout this site selection process and remain committed to maintaining an open dialogue with our stakeholders and the local community.’’
The MoD has now launched a 12 week public consultation running until February 20, 2015 in advance of a final decision on the selected site later in the year.
This includes four exhibitions for Capenhurst:
- December 9: noon to 8pm, Macdonald Craxton Hotel on Parkgate Road, Ledsham
- December 10: 11am to 8pm, Macdonald Craxton Hotel on Parkgate Road, Ledsham
- December 11: 1pm to 5pm, Capenhurst Village Hall on Capenhurst Lane
- January 20: noon to 8pm, Macdonald Craxton Hotel on Parkgate Road, Ledsham
All three dates at Macdonald Craxton Hotel will include workshops at 1pm, 3pm and 6pm.
A MoD spokesman said: “Please come along to find out more about the project and the decisions we need to make.
“You will have the opportunity to speak to our project team and to express your opinions in person.
“We will listen to the views of communities and local people before we select the interim storage site and all the comments we receive will be considered as part of our analysis of the options.”
The MoD says all the information is also available for comment on the internet or by post and it will accept comments by post or e mail.
If selected, CNS’s role in the project would involve developing a solution for the interim storage of the steel reactor pressure vessels that will be removed from the defuelled subs.
The vessels would be lifted from the subs at Devonport and Rosyth and then transported to the selected management facility, potentially at Capenhurst, for interim storage in advance of final disposal at the UK’s planned geological disposal facility.
Capenhurst already manages material owned by the MoD under another contract.
Mr Slater said at the time of the provisional announcement: “Our workforce is committed to providing the centre of excellence for the management of nuclear materials, decommissioning and recycling.”
The vessels, classified as intermediate level radioactive waste, each weigh between 90 and 135 tonnes according to the MoD.
In total they amount to less than 0.2% by volume of the UK’s national accumulation of intermediate level waste.
Commenting on the radiation risk for residents around the proposed storage, MoD documents point out: “The level of radiation exposure for local people will be subject to tight regulations, which require these levels to be kept to an absolute minimum.
“From our experience with similar sites and activities, there will be no measurable increase in radiation levels or associated health risks.”
The store, as with all nuclear activities, would be independently regulated to stringent standards, the MoD insists.
Chester MP Stephen Mosley has previously commented: “The team at Capenhurst are absolute professionals who are leading the way in nuclear technology in the UK.
“It is therefore not surprising that they have been listed as a candidate site for the nuclear submarine dismantling process.
“This is brilliant news for highly-skilled, long-term jobs and investment locally.”
Capenhurst Nuclear Services Limited commenced operations in 2012 following a long term contract with the country’s Nuclear Decommissioning Authority.
The company claims it has over 1,000 years of combined nuclear experience from across its highly skilled workforce.
Defence minister Philip Dunne MP has described earlier stages as ‘another step towards a safe and sustainable solution for the disposal of radioactive waste from our submarine fleet’.
He pointed out that all of the potential sites had a proven track record in handling radioactive material in a safe and secure way.
