This intervention, conducted at the EDF Nuclear Generation Limited (NGL) Sizewell B Power Station licensed site, was undertaken as part of the 2019/20 intervention plan operating reactors Supply Chain and Quality Assurance (QA) strategy.
During the Office for Nuclear Regulation’s (ONR) 20-22 January 2020 site inspection, I conducted a planned Licence Condition (LC) 17 (“Management Systems”) compliance inspection of the implementation of the licensee’s arrangements.
The intervention was performed in line with ONR's guidance requirements (as described in our technical inspection guides) in the areas inspected.
The inspection was conducted at EDF NGL Sizewell B Power Station and as part of the inspection I sampled the Supply Chain, Quality Assurance, Dry Fuel store, Equivalence and Obsolescence and System Engineering arrangements.
This was not a systems inspection
This LC17 inspection examined the progress of the resolution of regulatory issue 7315 (QA improvements). I am content that adequate progress has been made on the identification of shortfalls in the stations QA arrangements and an improvement plan developed to address the shortfalls.
On examination of the implementation of the Equivalence and Obsolescence process, it was found that the stations process did not follow the corporate arrangements. There was no local instruction in place. This is a shortfall in EDF NGL’s arrangements, which the station will rectify. A level 4 issue will be raised to monitor progress.
During the tour of working areas, a number of low-level conventional safety issues were found and brought to the attention of the Project Managers, who arranged for immediate rectification of the issues identified.
Overall, I am satisfied to rate the LC17 inspection as adequate (green) and the existing Level 4 regulatory issue 7315 requiring improvement to the station QA arrangements will remain extant and be monitored through regular visits to the station.
