Key findings, inspector's opinions and reasons for judgement made
In accordance with the Office for Nuclear Regulation’s (ONR’s) Dungeness B (DNB) intervention plan, ONR performs a series of planned compliance inspections of identified licence conditions (LCs) and other applicable legislation, to ensure that DNB is meeting its legal requirements.
LC17 requires that “The licensee shall, within its management systems, make and implement adequate quality management arrangements in respect to all matters which may affect safety.”
The aim of the inspection was to determine whether Dungeness B is exercising appropriate control, oversight and assurance of onsite contractors delivering nuclear safety related goods or services in respect to quality.
The relationships between EDF Energy and the contractor organisations are positive and constructive.
EDF has implemented an oversight and governance framework including regular accountability meetings with relevant contractors.
Whilst key performance indicator and quality metrics are being utilised to manage quality the effectiveness/adequacy of these is variable across the sampled contractors.
There were elements of good practice in some of the contractor’s quality management arrangements however these practices were not applied consistently across its contractors.
The flow down from the supply chain quality manual into implementation documents/deliverables was not fully clear, however Dungeness B explained that it understood that some aspects of quality oversight are carried out at a fleet level for these large permanent contractor partners.
Conclusion
Overall, I judge that further engagement by ONR with EDF at a fleet level is appropriate to allow a properly informed a judgement on the adequacy of the supplier quality oversight and supplier quality manual implementation. As such this intervention has not been rated.
It has been agreed internally that the ONR supply chain specialism will examine at a fleet level the adequacy of the line of sight from the supplier quality manual to implementation of oversight and accountability at stations and determine whether any further improvements are required to improve consistency of implementation at a working level.
