Heysham 1 receives Improvement Notice
Both reactors on station were not impacted by the event and continued to generate electricity as normal.
Since this event, both the station and regulator, the Office of Nuclear Regulation (ONR), have been investigating the cause of the leak. This investigation has shown that the cause of the pipe work failure was corrosion.
As a result of the regulator's preliminary investigation, the ONR has issued an Improvement Notice to EDF Energy and Heysham 1 Power Station, in relation to this incident.
