Key findings, inspector's opinions and reasons for judgement made
The purpose of this intervention was to review the approach taken by Hunterston B to declare reactor 4 fuel free and judge the adequacy of the quality plans and associated fuel records.
Prior to this intervention a review of the Hunterston B fuel free verification strategy was undertaken.
Conclusion
I was satisfied from the areas sampled that the approach taken by Hunterston B to declare reactor 4 fuel free meets the legal requirement for compliance with LC25 - operational records. During this inspection an area of improvement was identified on one of the procedures. Since Hunterston B has successfully defueled both its reactors, this area of improvement will be pursued via the other defueling reactors. Notwithstanding this, I judge that an inspection rating of Green (no formal action) is merited.
