This is a planned intervention 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).
I (a supporting site inspector) completed a planned compliance inspection against nuclear site Licence Condition 36 (Organisational capability).
Three ONR Issues (181, 805 and 806) were discussed with representatives of the licensee, and evidence of activities to address those Issues was reviewed.
Three incidents on the site were followed up (CR's 821564, 850566, and 849715).
I consider that the licensee has completed their review of nuclear baseline in line with their published arrangements and that the formal Baseline Statement reflects an adequate assessment of the work undertaken. I have noted that the evidence in support of the published baseline figures for DNB are historical in nature, and that benefit would be gained from establishing the relationship between planned workload at site (including future plans for safety related performance improvement) and the nuclear safety baseline.
I consider that the licensee has undertaken wider resource management activities to a good standard, and has utilised a wide range of resource management tools (as both mandated under their arrangements and, in a number of cases, more widely deployed than the minimum required). The evidence examined indicated that resource management was undertaken in a proactive manner, and appropriate planning timescales were being used.
I consider that the Management of Change (MoC) process is implemented adequately at DNB, and that, additionally, through the Resource Review Group, the licensee utilises the knowledge of the senior management team as an early filter to confirm the need for the MoC process.
I consider that, in constructing the Baseline Statement, there is further opportunity for the licensee to relate resource composition at site to planned changes in key performance indicators and planned project work, rather than just historical activities. Therefore, in relation to the LC36 compliance inspection, I have assigned an IIS rating of 3 (adequate) to LC36.
In following up events at site, I consider that each event was investigated in accordance with the licensee's arrangements, that an appropriate level of investigation was conducted, relating to the relative severity of each event, and that all actions set were appropriate, and where required to be completed prior to the date of my inspection, have been completed. I do not consider that further follow up of any of the events is merited, as no wider safety issues or trends have been identified.
The licence conditions were inspected against ONR's published guidance requirements (as described in our technical inspection guides) in the areas inspected.
From the evidence obtained during this intervention, no matters have been identified that are likely to have a significant impact on nuclear safety on the station at this time. Therefore, no additional regulatory action arising from this visit is considered necessary at this time.
The planned interventions set out in the Integrated Intervention Strategy for Dungeness B remain valid and will be followed for future inspections.
