Question to the Ministry of Defence:

To ask the Secretary of State for Defence, pursuant to the Answer of 8 May 2025 to Question 49938 on Nuclear Submarines: Safety, what the Category (a) A and (b) B Nuclear Site Event Reports recorded at (i) Coulport and (ii) Faslane were.

Nuclear Site Event Reports 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.

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 hon. 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.
