This was a planned inspection at EDF Energy Nuclear Generation Ltd.'s (NGL's) Hinkley Point B power station, undertaken as part of the planned intervention strategy for the Civil Nuclear Reactor Programme (CNRP) of the Office for Nuclear Regulation (ONR)
The work was carried out in line with the planned inspection programme contained in the Hinkley Point B Integrated Intervention Strategy (IIS).
Two Environment Agency Inspectors and I (the nominated ONR site inspector for Hinkley Point B) carried out an inspection of the Radioactive waste Management Arrangements on site.
I held a number of information gathering meetings with NGL.
The intervention was performed in line with ONR's guidance requirements (as described in our technical inspection guides) in the areas inspected.
Not applicable. No system inspections were carried out during this visit.
The Environment Agency inspectors and I noted from the Radioactive Waste Materials Arrangements inspection that arrangements were in place to ensure that radioactive and conventional wastes were adequately managed. Staff in a variety of roles demonstrated an understanding of these arrangements appropriate to their role. The corporate Sustainable Approach to Waste Management is in the process of being embedded at the station and further work is required in this area to fully implement it. No non-compliances were noted but several recommendations were made to show continued application of Best Available Technique. In particular, improvements to green stream segregation may contribute to optimising waste disposals.
I held information gathering meetings with station staff on a range of topics including the plant status and activities, failure of a section of Nitrogen pipework, the revision of the Technical Specification relating to the kerosene storage tanks, the proposed extension to the Reactor 4 operating period and interactions with the proposed Hinkley Point C station.
There are no findings from this inspection that could significantly undermine nuclear safety. No ONR actions were raised during this inspection.
