Key findings, inspector’s opinions and reasons for judgement made

The purpose of this planned inspection was to observe Dounreay’s annual safety emergency exercise demonstration. In line with Dounreay’s arrangements this was an enhanced facility exercise rather than a site wide exercise, which reflects the reducing hazard potential of the site as it is steadily being decommissioned whilst still providing a robust demonstration of Dounreay emergency arrangements.

Overall I was satisfied that during the excerise Dounreay successfully evacuated the affected facilities, accounted for its staff, and recovered the situation in a timely manner. Had this been a real event I am satisfied that Dounreay would have dealt with it in an effective manner. On this basis I have awarded a Rating of Green – Adequate.
