Dungeness A – Compliance Inspections and AROSES meeting

Executive summary

Purpose of intervention

This report covers an inspection of Magnox Ltd’s Dungeness A nuclear licensed site on 18-21 May 2015. This inspection was undertaken as part of a programme of planned interventions as outlined in the Dungeness A IIS plan for 2015/16.

The inspection looked at the site’s arrangements for radiological protection, reporting of events on site and management systems. I also attended the sites Annual Review of Safety, Environment and Security (AROSES).

Interventions Carried Out by ONR

During this intervention, I carried out Licence Condition (LC) compliance inspections to verify compliance with the following Licence Conditions:

My inspections were carried out against the requirements of LC7, 17 & 18 and ONR’s published inspection guidance associated with these Licence Conditions.  The inspection comprised office-based examination of procedures and records and interviews with staff.

Whilst on site I held meetings with the licensee to discuss follow up the status of actions and investigations from recent events. I also met with the site safety representatives.

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 LC18 – radiological protection, along with a team of ONR radiological protection specialists. I judged the arrangements and implementation of these arrangements to be adequate. Overall I judged the licensee to be compliant with the Ionising Radiation Regulations (IRR) and ONR inspection guidance associated with LC18.

I inspected compliance with LC 7 – incidents on the site and reporting process. I was satisfied that the licensees’ arrangements meet the required standard as defined in ONR guidance and these were adequately implemented. I considered the Learning from Experience (LFE) form in use on the site to be a good practice example, identifying both causes and precursors. Adequate screening and sentencing arrangements were evident, and actions resulting from investigations were well managed. Overall, I rated compliance with LC7 to be adequate.

I inspected compliance with LC 17 – management systems. Due to the combined company and site procedures, the resulting management systems are quite complex, but efforts are being made by the site to simplify the systems. A reasonable level of auditing, oversight and process ownership is applied to the systems, which demonstrated adequate governance is in place. I was satisfied that the arrangements and their implementation broadly met the standards defined in ONR guidance. Overall I rated compliance with LC17 to be adequate.

I met with site safety representatives. We discussed current issues and plans on site and feedback from the safety rep interactions with management.

I attended the Dungeness Annual Review of Safety Environment and Security (AROSES), where the sites performance for the previous year was discussed. No significant actions or issues relating to safety or security regulation were raised.

Conclusion of Intervention

From the evidence gathered during this intervention, I judged the licensee’s compliance with LC7, 17 & 18 to be adequate. A number of areas of good practice were highlighted and also some minor actions were raised for further improvement. These actions will be followed up by the ONR site inspector as part of routine regulatory interactions with the licensee.
