Nuclear Power Stations: Safety

Question

The Timetable for the next periodic safety reviews of each of the operating nuclear power stations is included below. The nine stations are the seven Advanced Gas-cooled Reactor (AGRs) sites, the single Pressurised Water Reactor at Sizewell B and the remaining operating Magnox reactor at Wylfa.

An environmental impact assessment is undertaken by each licensee covering the radiological impact of routine discharges. Such assessments are carried out separate to the PSR submitted to ONR by the licensee under Licence Condition 15, and are regulated by the appropriate UK environmental agency – the Environment Agency, Scottish Environmental Protection Agency, or Natural Resources Wales – in each case.

While there is no legal requirement for public involvement in PSRs, the decision of whether to include public involvement is taken at the discretion of each station licensee. ONR completes an assessment of the licensee's submission prior to the decision date to ensure it meets the expectations set out in its guidance and that it provides an adequate demonstration of the future safe operation of the plant – see ONR guidance at:
