The Office for Nuclear Regulation (ONR) has granted a short extension to an improvement notice issued following a health and safety incident at Hartlepool Nuclear Power Station.
On 9 November 2025, two EDF technicians were carrying out maintenance work when a joint on a system was disconnected that contained hydraulic oil under pressure which was then released, coming into contact with the workers.
Both employees attended hospital as a precautionary measure. There was no risk to nuclear safety, the public or the environment.
ONR acknowledges that EDF has made progress in meeting the requirements of the notice originally due for completion by 17 April. Therefore, ONR has agreed to the extension to allow the company to demonstrate that suitable arrangements are in place.
This includes ensuring employees undertaking the maintenance activity have access to the information they need to carry out their work safely.
ONR will continue to monitor the progress made to ensure full compliance, which is now scheduled for 29 May 2026.
