Hide AdNobody was injured as a result of the incident, and there was no risk to nuclear safety, the public or the environment, says the ONR.
However, ONR identified the potential for serious personal injury, if people had been present in the area near the valve.
Mike Webb, ONR’s Superintending Inspector for Operating Reactors, said: “Our investigation found that EDF had failed to ensure that the valve system was properly maintained and, by failing to do this, EDF had put at risk the safety of their employees.
“We will engage with EDF during the period of the improvement notice to ensure positive progress is made to address the shortfall.”
