More than 500 safety events have been recorded at the home of the UK's nuclear deterrent since 2006, the MoD has revealed.

Defence Minister Stuart Andrew disclosed the figure in a letter in response to a parliamentary question from Edinburgh SNP MP Deidre Brock.

In total, 505 "events" were recorded over the past 12 years at HM Naval Base Clyde atFaslane, home to most of the UK's nuclear submarine fleet.

In the letter he states:

"These events may be near-misses, equipment failures, human error or procedural failings.

"They are raised, however minor they may appear, to encourage a comprehensive, robust reporting culture, undertake learning from experience and to take early corrective action."

There were two Category A incidents listed from 2006 and 2007.

The letter states that Category A events have "actual or high potential for radioactive release to the environment of quantities in excess of IRR99 notification limits".

However, the minister said that in "neither event was any radiological contamination evident".

Figures show an increase in recorded incidents in recent years with 80 in 2016 and 73 last year.

An MOD spokesperson said:

"None of the events caused harm to the health of any member of staff on the Naval Base, or to any member of the public, and the safety significance has remained very low.

"The MOD, however, takes all such incidents, no matter how minor, extremely seriously and ensures they are investigated and appropriate measures put in place to prevent a recurrence."

Kate Hudson, CND general secretary, said: "When the MoD took the decision to censor annual nuclear safety reports which had previously been made public, we feared that safety at Faslane was worsening.

"While we welcome a return to a degree of transparency, the figures in the defence minister's letter confirms our fears, revealing a catalogue of accidents in the last three years.

"Many of these incidents involved the Trident submarines which carry Britain's nuclear weapons.

"The incidents add to the dire warnings in September's Public Accounts Committee report which revealed serious infrastructure problems, including huge delays and overspending.

"We hope to see a return to annual reports of the Defence Nuclear Safety Regulator being made available to the public and more transparency in general.

"This information is a requirement in a functioning democracy."
