Dungeness A - Compliance inspection of LC12, LC36 and updates in relation to LC15

Executive summary

Purpose of Intervention

This was one of a series of planned Licence Condition (LC) compliance inspections of the Dungeness A Site for 2017/18.

The aims of the inspection were to:

This intervention was also an opportunity to engage with the licensee on the LC 15 Periodic Review of Safety and to follow up on issues raised at previous interventions.  The intervention coincided with the licensee’s Executive Safety Review of the site.

The inspection commenced with the licensee providing an overview of the implementation of arrangements followed by a site walk-down of the Dungeness A site.

Interventions Carried Out by ONR

LC 12 requires the licensee to make and implement adequate arrangements to ensure that only duly authorised and SQEP persons perform duties which may affect safe operations on the site. It also requires the licensee to provide for the appointment of duly authorised persons (DAP) to control and supervise operations which may affect plant safety.

LC 36 requires the licensee to provide and maintain adequate financial and human resources to ensure the safe operation of the licensed site and to make and implement adequate arrangements to control any change to its organisational structure or resources which may affect safety.

On 22, 23 and 24 May 2018, I carried out a combined LC 12 & 36 compliance inspection. The inspection comprised discussions with ML staff, a walk-down of site 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 the authorisation of DAPs and the arrangements for determining whether an individual is SQEP and sampled training records relating to key operational personnel. I also sampled the organisation structure and the licensee’s arrangements for confirming that adequate organisation resources were being made available.

I judged that, on the evidence examined, the licensee has adequate arrangements in place for the authorisation of DAPs and SQEPs and that that adequate human resources were being made available.

There were no items of concern regarding LC 15 compliance.

I considered it welcome that the Magnox Executive Team was on site to examine the condition of the plant and I was satisfied that they understood the asset condition issues needing to be addressed.

Conclusion of Intervention

From the evidence examined during the inspection, I judge that the licensee’s arrangements for compliance with LC 12 and 36 are adequate and that they are being adequately implemented.
