Hinkley Point A – Licence Condition 12, 22, 26 and 28 Compliance Inspection, Contamination Control Exercise and progress meetings

Executive summary

Purpose of intervention

This report describes an ONR intervention conducted at Magnox Ltd’s Hinkley Point A nuclear licensed site, undertaken as part of a series of routine interventions set out in the Integrated Intervention Strategy document.  The opportunity was also taken to familiarise the incoming Nominated Site Inspector to the licensee Lead Team, the site and current decommissioning operations.

Interventions Carried Out by ONR

The main intervention was to inspect licensee arrangements necessary to demonstrate compliance with licence conditions 12, 22, 26 and 28.   

In addition the following interventions were included:

Explanation of Judgement if Safety System Not Judged to be Adequate

This intervention was not a Safety System inspection.

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

Licensee arrangements necessary to demonstrate compliance with licence conditions 12, 22, 26 and 28 were examined and judged to be adequate.

Judgement was based on inspecting a selection of applicable management arrangements as well as reviewing the implementation of such arrangements. Individuals with responsibilities to deliver compliance were also questioned during the intervention. These individuals were clearly knowledgeable, enthusiastic and accepting of any regulatory advice.

 Contamination control measures during a hypothetical spillage incident were also inspected. It was clear that the licensee had made significant improvements following the shortfalls identified during the 13 November 2014 Level 1 Emergency Exercise.  It is expected that improved and sustained resilience in this area will be evident during future emergency exercises.

Although compliance with licence condition 36 was not a focus for this intervention, it was necessary to stress to the licensee that any future organisational changes should:

Fully consider the operations at the site (as defined by licence condition 1) when determining the nuclear baseline;

Be cognisant of the principles described within the Nuclear Industry Code of Practice ‘Nuclear Baseline and the Management of Organisational Change’ and relevant good practice.

Conclusion of Intervention

No significant actions were generated.
