The purpose of this intervention was to undertake Licence Condition (LC) compliance inspections at EDF Energy Nuclear Generation Ltd's (NGL's) Dungeness B power station, in line with the planned inspection programme contained in the Dungeness B Integrated Intervention (IIS) plan for 2016/17.
This intervention included compliance inspections against the following Licence Conditions:
I also undertook a number of engagements with the licensee representatives, which covered the following topics:
Not applicable as no system inspection was undertaken during this intervention.
I undertook a planned intervention against LC 11, during which I:
Overall, I am satisfied that the licensee can effectively deal arrangements for the delivery of examination, maintenance, inspection and testing meet the requirements of the safety case, and thus, adequately demonstrate compliance against the licence condition 28.
The intervention was performed in line with ONR's guidance requirements (as described in our technical inspection guides) in the areas inspected.
In relation to LC 11, I judged that an IIS rating of ‘Amber' is warranted on the basis that the station's emergency plan does not adequately reflect the current organisational arrangements for emergency preparedness and response. That said, the emergency handbook detailing the station's emergency arrangements is suitable and sufficient. I judge the individuals required to respond to such an incident are competent and the arrangements are tested routinely. I will write to the station seeking resolution of this shortfall and a regulatory issue has been raised to monitor progress.
In relation to LC 28, I judged that the IIS rating of ‘Green' is warranted on the basis that the station could demonstrate that plant which may affect safety is subject to periodically and systematic maintenance in line with safety case requirements.
There are no findings from this inspection that could significantly undermine nuclear safety.
