Conclusion of Intervention

Based on the evidence sampled during this inspection I judged that measured against ONR’s expectations for LC13 (Nuclear Safety Committee), the intervention rating is GREEN (no formal action), with identification of three areas of good practice, four regulatory observations (areas for improvement) and no regulatory issues. The observations and recommendations were communicated to and accepted by the licensee during the intervention feedback.
