Plant Operation

The Office of Nuclear Regulation granted permission for the Heysham A-1 nuclear unit in the UK to return to the grid after the discovery of a crack in a boiler spine in August 2014 led to it being shut down as a precautionary measure.

The ONR carried out an independent assessment and concluded that operator EDF Energy had demonstrated the continued safe operation of the advanced gas- cooled unit, which began commercial operation in 1989. EDF Energy confirmed on social media that the unit was back online and producing electricity.
