The UK government’s nuclear safety watchdog has ordered Babcock, the multinational company that runs the dockyard for the Royal Navy, to rerun the exercise, codenamed Nightstar, in March because of mistakes made last September.
An inspection by the Office for Nuclear Regulation (ONR) concluded that there were flaws in the way that staff looked after injured people during the exercise. There were also communication and command problems in dealing with the imagined accident.
The revelation has prompted “unease” about safety at the naval base, according to the local MP. Anti-nuclear campaigners have highlighted the serious risks of accidents, and demanded higher standards.
The problems with the Nightstar exercise on 30 September 2015 were disclosed in the ONR’s latest three-monthly report on Rosyth, posted online. Though inspectors thought that some of the exercise procedures were adequate, others were not.
