Explanation of Judgement if Safety System Not Judged to be Adequate


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

The assessment team considered Delta 53 to be an adequate demonstration of the site’s emergency arrangements, but areas for improvement were identified, in particular relating to the integration of operations in the site emergency control centre and the police control room. Our findings will be confirmed in a letter to DSRL.

The radiation protection specialist inspector noted the good standard of dose assessment and radiation protection advice now being, generated and the knowledge of those spoken to during the intervention. He is confident that DSRL have made sound arguments covering, providing optimised solutions as the work progresses to minimise operator doses.

Conclusion of Intervention

Overall, we consider that DSRL met the required standard in the areas inspected.  We did not identify any matter impacting on nuclear safety that required immediate regulatory action.
