Dungeness Licence compliance and CHS inspection and PSR findings review

Executive summary

Purpose of Intervention

This was one of a series of planned Licence Condition (LC) compliance inspections of the Dungeness A Site for 2018/19.

The aims of the inspection were to:

Interventions Carried Out by ONR

I carried out a review of completion of the PSR responses to the ONR assessment findings of the 2018 PSR submission in conjunction with the DNA PSR Project Inspector

I inspected the licensee’s compliance with Licence Conditions 7, 17 and 26.

I participated in an inspection by the conventional health and safety inspector

I also undertook meetings with the safety representatives, PSR team and the DNA internal regulator.

Explanation of Judgement if Safety System Not Judged to be Adequate


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

Magnox Ltd has now completed the work providing responses to the findings, observations and queries raised by ONR during its assessment of the PSR submission. The inspection did not uncover any incompleteness in the responses.

The plans for the site demolition work to remediate the degraded annexes and boiler cells is currently planned to take until 2026, which puts it beyond the estimated date where its integrity can be guaranteed in the independent structural engineer’s report. As a result, studies are underway as to how these structures can be maintained in a safe state until they are demolished.

From the evidence examined during the inspection I judged that the licensee has adequate arrangements in place for compliance with LC’s 7, 17 and 26.

Safety culture on the site has degraded over recent months indications of this include for example, the poor observance of the no eating or drinking rules in certain areas and high numbers of spurious fire system and radiation monitor alarms.

Conclusion of Intervention

Magnox Ltd has completed their responses to ONR’s findings on the PSR submission and ONR now has the necessary commitments and assurance to deliver a positive decision letter by the due date.

From the evidence examined during the inspection, I judged that the licensee’s arrangements for LC’s 7, 17 and 26 were adequate and satisfactory progress is being made in planning for the proposed acceleration of the site’s demolition and dismantling in view of the asset care issues present on the site.

It is recognised that the general standards of workplace behaviour are not as high as expected for a nuclear site. Particularly with respect to the number of spurious fire alarms, observance of RCA no eating rules and standards of toilet hygiene. Site are aware of these issues and are formulating a plan of interventions to improve the situation.
