Sizewell A Fuel free verification inspection Annual review of Safety

Executive summary

Purpose of intervention

I carried out planned inspections in accordance with the Office for Nuclear Regulation’s (ONR’s) integrated intervention strategy for 2014/15 at the Sizewell A licensed site.

Interventions Carried Out by ONR

I carried out an inspection of the licensee’s arrangements for demonstrating that all fuel had been removed from the site.  I also participated in the annual review of safety and pre-meeting site walk-down.

Explanation of Judgement if Safety System Not Judged to be Adequate


Key Findings, Inspector's Opinions and Reasons for Judgements Made

I consider that the licensee has done all that is reasonably practicable to demonstrate that the spent fuel pond is free from fuel.  As the licensee has previously made a similar demonstration that the reactor buildings are free from fuel, which I commented on in a previous report, I consider that it is therefore very unlikely that any fuel remains on site.

The licensee presented its view of safety, security and environmental performance for the preceding year in an open and honest fashion.  ONR concurred with the licensee that the Site’s performance had been generally good, with the highlight being the safe completion of defueling ahead of schedule.  However, there have been incidents within the period, the most significant of which was the fall from height of a contractor in August 2014 that Site has taken seriously, learning the lessons and promulgating these to the Magnox Ltd fleet.

Conclusion of Intervention

I found no issues that significantly affect nuclear safety and nothing that required me to take further regulatory action.
