Explanation of Judgement if Safety System Not Judged to be Adequate


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

For the LC 28 inspection, based on the discussions and explanations given, including the sample inspected, on this occasion I am satisfied that there were no shortfalls identified with the implementation of the arrangements for LC28 - EIMT. Therefore I judged this compliance inspection to have a ‘GREEN’ rating. There were no shortfalls identified in the Safety Case and the route to the EIMT plan via the Engineering Schedule, Maintenance Instructions or the use of data provided from maintenance activities. I was also satisfied with regard to my other interventions that there were no shortfalls and no need for any regulatory action at this point.

Conclusion of Intervention

It is ONR’s opinion, that from the sample inspected, the implementation of the established arrangements within the ATC with respect to Licence Condition 28 is to a ‘GREEN’ rating. There are no other findings from this inspection or the other interventions in this report that could significantly undermine nuclear safety.
