Subject(s) of inspection
- LC11 – Emergency arrangements – Rating – Green
Key findings, inspector’s opinions and reasons for judgement made
This inspection, one of a series of planned inspections for 2022 at the Sizewell A nuclear site, was undertaken to judge the adequacy of compliance with licence condition (LC) 11 – Emergency arrangements.
During this inspection ONR assessed the Level 1 Emergency Exercise “Phoenix”. This inspection consisted of observing Magnox Limited staff at Sizewell A nuclear licensed site deploying its emergency arrangements to control a simulated emergency incident.
In my opinion the planning for the exercise was comprehensive, and the scenario was sufficiently challenging for Sizewell A site to adequately demonstrate its arrangements for dealing with an accident arising on the site. I identified a number of points of good practice but also made a small number of observations, which were conveyed to the licensee in the post-exercise de-briefing meeting.
Taking into account the exercise planning/scenario and the observations made by the ONR team during the exercise, I consider the emergency exercise to be an adequate demonstration of the site’s emergency arrangements made under Licence Condition 11.
Based on the evidence above I am of the view that the licensee adequately demonstrated its LC11 arrangements. As such an inspection rating of green is merited.
