The Office for Nuclear Regulation (ONR) has confirmed that EDF Energy Nuclear Generation Ltd, the licensee, has demonstrated that Sizewell B nuclear power station in Suffolk can continue to operate safely until 2025.
This decision follows comprehensive assessment of the Periodic Safety Review (PSR), a ten-yearly review of safety required on all nuclear sites.
Although the PSR is not complete until an agreed programme of work has been delivered, the ONR has identified no issues of nuclear safety significance that could impact generation at Sizewell B to the next date of review (2025). ONR identified a number of areas for improvement for the licensee and will monitor its progress in completing this work.
The ONR’s assessment will be published in due course.
