MoD admits ‘Category A’ event at HMNB Clyde which will raise concerns about maintenance of Trident nuclear submarines

‘Potentially serious’ event at HMNB Clyde prompts concerns about maintenance of Trident submarines

Category A events are defined as those which carry “actual or high potential for radioactive release to the environment”.

The revelation will raise serious concerns about how the Trident nuclear submarines in Scotland are being maintained. It is also likely to prompt questions over transparency and why the incident was not known about until now.

HMNB Clyde houses every Royal Navy submarine, including the Vanguard-class vessels which are armed with Trident missiles.

On Wednesday afternoon, the SNP demanded an urgent explanation from the Labour Government in Westminster over a “catalogue of failures” including separate contamination nearby.

The MoD declined to offer specific details of the incident, which was first reported by the Helensburgh Advertiser. This means it was unclear if any radiation was leaked into the environment or if there was a risk of this taking place.

The incident is not the first category A incident to take place at Faslane, with the MoD having reported two such cases from 2006 to 2007 and a third that took place in 2023.

The incident was disclosed in a written parliamentary answer by Maria Eagle, the procurement minister, after she was asked to provide the number of Nuclear Site Event Reports (NSERs) at the Coulport and Faslane naval bases.

She said there had been one category A event at Faslane between Jan 1 and April 22, two category B, seven category C and four category D. A further five events were deemed to be “below scale”, meaning they were less serious.

Nearby Coulport, where the UK’s nuclear missiles and warheads are stored, had four category C and nine category D events over the same period.

Ms Eagle told Dave Doogan, the SNP MP who tabled the question: “I cannot provide specific detail for the events as disclosure would, or would be likely to, prejudice the capability, effectiveness or security of any relevant forces.

“I can assure the honourable member that none of the events listed in question 49938 caused harm to the health of any member of staff or to any member of the public and none have resulted in any radiological impact to the environment.”

She also said that NSERs “are raised to foster a robust safety culture that learns from experience, whether that is equipment failures, human error, procedural failings, documentation shortcoming or near-misses”.

Category B incidents are defined as having “actual or high potential for a contained release within [a] building or submarine or unplanned exposure to radiation”.

Category C incidents have “moderate potential for future release”, while category D incidents are unlikely to prompt any release but “may contribute towards an adverse trend”.

Radioactive water leak

It emerged last week that radioactive water from the Coulport and Faslane bases, which are situated near Glasgow, was allowed to leak into the sea after several old pipes burst.

The substance was released into Loch Long because the Royal Navy inadequately maintained a network of around 1,500 pipes on the base, a regulator found.

The Scottish Environment Protection Agency, the pollution watchdog north of the border, found up to half the components at the base were beyond their design life.

David Cullen, a nuclear weapons expert at the Basic defence think tank, said attempts to hide previous serious incidents from the public had been “outrageous”.

Mr Cullen said: “The MoD is almost 10 years into a nearly £2bn infrastructure programme at Faslane and Coulport, and yet they apparently didn’t have a proper asset management system as recently as 2022.

“This negligent approach is far too common in the nuclear weapons programme, and is a direct consequence of a lack of oversight.”

Government accused of ‘cover-up’

Keith Brown, the deputy leader of the SNP, accused the Government of a cover-up in relation to the incident at Faslane.

Mr Brown said: “Nuclear weapons are an ever-present danger and this new information is deeply worrying.

“With repeated reports of serious incidents at Faslane and now confirmed radioactive contamination in Loch Long, it’s clear these weapons are not only poorly maintained but are a direct threat to our environment, our communities, and our safety.

“Worse still, the Labour Government is refusing to provide any details about the category A incident, or the full extent of the contamination, including who could potentially be affected.”

The SNP has vowed to scrap Trident, despite consensus in Westminster and among defence experts that the world is now more dangerous than at any point since the Cold War.

The accusations over a cover-up come after The Telegraph disclosed last month that Britain had secretly offered asylum to almost 24,000 Afghan soldiers and their families.

The Government earmarked £7bn to relocate Afghans to the UK over five years after they were caught up in the most serious data breach in history.

Despite enormous costs to the taxpayer, the breach was kept secret from the public for 683 days by two successive governments after the first use of a super-injunction by ministers.

An MoD spokesman said: “We place the upmost importance on handling radioactive substances safely and securely. Nuclear Site Event Reports demonstrate our robust safety culture and commitment to learn from experience.

“The incidents posed no risk to the public and did not result in any radiological impact to the environment. It is factually incorrect to suggest otherwise. Our Government backs our nuclear deterrent as the ultimate guarantor of our national security.

The MoD said it was unable to disclose details of individual incidents for “national security reasons”. However, it is understood all the NSERs were categorised as having a “low safety significance”.
