In line with industry good practice, and in common with other defence and civil nuclear sites, Her Majesty’s Naval Base Clyde has a well-established system for raising NSERs and investigating and categorising them according to their safety significance, whether equipment failures, human error, procedural failings, documentation shortcomings or near-misses.

The safety significance of all reported events remains low and they are all below Level 1, the lowest level of the seven-point International Nuclear and Radiological Event Scale (INES).

None of the events caused harm to the health of any member of staff at the Naval Base or to any member of the public, and no event resulted in any unauthorised discharge of radioactive waste to the environment.
