Hinkley Point A (HPA), Berkeley (BRK) and Oldbury (OLD) compliance inspection

Executive summary

Purpose of Intervention

This inspection at Magnox Limited (ML) Hinkley Point ‘A’ Site, Berkeley and Oldbury sites were some of a series of planned inspections for the sites for 2018/19 in support of ONR’s Decommissioning Fuel and Waste sub-division strategy.

The aims of the inspection were to:

Interventions Carried Out by ONR

LC 32 requires the licensee to make and implement adequate arrangements to minimise, so far as is reasonably practicable, the rate of production and volume of radioactive waste generated, and for the control of such waste, once generated.

LC 34 requires the licensee to ensure that the control and containment of radioactive materials and radioactive wastes so far as is reasonably practicable to prevent their leakage or escape, and the detection, notification, recording, investigation and reporting of any leakage or escape that occurs.

LC 35 requires the licensee to make and implement adequate arrangements for decommissioning facilities on a licensed nuclear site.

I carried out combined LC 32, 34 & 35 compliance inspections on the Hinkley Point ‘A’, Berkeley and Oldbury sites. The inspections comprised discussions with ML staff, a site walk-down and reviews of relevant records and documentation. 

Explanation of Judgement if Safety System Not Judged to be Adequate


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

During my inspection, I sampled the management arrangements for radioactive waste arising from the decommissioning activities undertaken on the site to determine if the wastes arising are being adequately managed and that sufficient and effective plans were in place for the disposition of waste generated.

I judged that, on the evidence examined, the licensee has adequate arrangements in place for the management of radioactive waste and for the control and containment of waste arising from their decommissioning activities.

During the inspection, I also reviewed the adequacy of plans for the decommissioning of the site and judged that the licensee has adequate plans to progress the decommissioning of the site towards defined end-states.

Conclusion of Intervention

From the evidence examined during the inspection, I judge that the licensee’s arrangements for compliance with LC 32, 34 and 35 on all three sites are adequate and that they are being adequately implemented.
