This is a planned inspection at EDF Energy Nuclear Generation Ltd's (NGL's) Dungeness B (DNB) power station, undertaken as part of the planned intervention strategy for the Civil Nuclear Reactor Programme (CNRP) of the Office for Nuclear Regulation (ONR).
We (superintending inspector and nominated site inspector) attended the ONR Annual Review of Safety (ARoS) meeting on 26 June 2014, and undertook an associated plant walkdown during the afternoon of 25 June 2014. We also observed the Environment Agency (EA) Annual Review of Environment (ARoE) meeting which followed the ARoS.
I (nominated site inspector) held a routine meeting with NGL's internal regulator.
As part of information gathering we (electrical engineering inspector and nominated site inspector) followed up an incident on the site that occurred on 27 April 2014 caused by a fault on the off site 400kV system. I (nominated site inspector) also followed up a separate incident on the site.
In relation to the ARoS, the main objectives of the meeting were to provide ONR with a summary of the operation of the station in the preceding period, review performance against the statements made at the previous meeting, and provide a statement about the intentions for improved operation in the next period, covering matters which may affect safety on the site. Taking into account the pre-meeting preparation relating to a detailed Information Pack provided by DNB, a plant walkdown and the meeting itself the agreed objectives of the ARoS were met.
In relation to the other activities undertaken in this intervention, no key findings arose.
The licence conditions were inspected against ONR's published guidance requirements (as described in our technical inspection guides).
