The intervention included a compliance inspection against site Licence Condition 32 (LC 32 - accumulation of radioactive waste).

Explanation of Judgement if Safety System Not Judged to be Adequate

Based on the evidence sampled during this inspection we judged that the solid and gaseous radioactive waste systems meet the requirements of the safety case.

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

In relation to the system based inspection of the solid and gaseous radioactive waste systems, we made the following observations and judgements:

With regard to the LC 32 compliance inspection, we made the following observations:

The intervention was performed in line with ONR’s guidance requirements (as described in our technical inspection guides) in the areas inspected.

Conclusion of Intervention

From the evidence gathered during the system based inspection of solid and gaseous radioactive waste systems, we assigned inspection ratings of ‘Green' (no formal action) for LC 10, LC 23, LC 24, LC 27, LC 28 and LC 34.

From the evidence gathered during the LC 32 compliance inspection, we assigned an inspection rating of ‘Green'.
