LC18 Compliance Inspection and SSG Meeting

Executive summary

Purpose of intervention

This report covers an inspection of Magnox Ltd’s Sizewell A nuclear licensed site on 2-4 June 2015. This intervention was undertaken as part of a programme as outlined in the Sizewell A IIS plan for 2015/16.

Interventions Carried Out by ONR

During this intervention, I carried out Licence Condition (LC) compliance inspections to verify compliance with LC18 – Radiological Protection. The inspection was carried out against the requirements of LC18 and ONR’s published inspection guidance associated with this Licence Condition.

I also attended the Sizewell Site Stakeholder Group meeting on 4th June.

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable – This was not a Safety Systems Inspection.

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

I inspected compliance to Licence Condition 18 – Radiological Protection, along with a team of ONR Radiological Protection specialists. Overall I judged the Licensee to be compliant with the Ionising Radiation Regulations (IRR) and ONR inspection guidance associated with LC18. A number of areas of good practice were highlighted and the sites overall performance in terms of dose rates and the low number of radiological events was considered positive. Some minor improvements were identified which the licensee agreed to take forwards. The timeliness of refresher training for Radiological Protection Supervisors was identified as an issue, which the licensee has agreed to review and address.

I attended the Sizewell Site Stakeholder Group (SSG) meeting, where I provided a summary of the ONR activities in relation to the Sizewell A site from the previous reporting period. Minutes of the meeting were taken by the SSG Secretary and will be provided in due course. No significant actions or issues related to safety or security regulation in the Sizewell A site were raised.

Conclusion of Intervention

From the evidence gathered during this intervention I judged the licensee’s compliance with LC18 to be adequate. A number of areas of good practice were highlighted and also some areas for further improvement were identified for the licensee to take forwards. One minor action was raised regarding the status of training and authorisations for Radiological Protection Supervisors. This action will be followed up by the ONR Site Inspector as part of routine regulatory interactions with the licensee. No matters were identified that may impact on nuclear or radiological safety.
