Sizewell B - Planned Compliance Inspections
- Site: Sizewell B
- IR number: 18-084
- Date: June 2018
- LC numbers: 11, 36
Purpose of Intervention
The purpose of this intervention was to undertake licence condition (LC) compliance inspections at EDF Energy Nuclear Generation Limited’s (NGL) Sizewell B Power Station, in line with the ONR’s Operational Facilities Division intervention strategy. The intervention was carried out by the ONR site inspector, supported by a number of specialist inspectors.
Interventions Carried Out by ONR
We observed Exercise Akita, designed to demonstrate Sizewell B’s capability to deal effectively with any accident or emergency arising on-site.
The intervention was performed in line with ONR's guidance requirements (as described in our technical inspection guides) in the areas inspected.
Explanation of Judgement if Safety System Not Judged to be Adequate
Not applicable – no system based inspections were completed during this intervention.
Key Findings, Inspector's Opinions and Reasons for Judgements Made
- Exercise Akita - The scenario, which involved a loss of power and a security incident was designed to test the interoperability of the power station’s emergency arrangements with those of responders from the emergency services. Commanders were challenged to prioritise and manage a large number of time dependant demands to ensure the safety and security of the site. We judged that emergency exercise was a successful demonstration of the station’s emergency arrangements and capability to respond to an emergency. We judged that the overall standard of compliance was consistent with relevant good practice and awarded the following inspection rating against LC11: Green.
- Licence Condition 36 - I reviewed NGLs process to identify and prioritise investment necessary to ensure safety systems continue to deliver their safety functions. Overall, I am satisfied that the prioritisation of work is informed by an effective understanding of the potential nuclear safety benefits and risks. On this basis, I judge that the following inspection rating is appropriate: Green
Conclusion of Intervention
There are no findings from this inspection that could significantly undermine nuclear safety. At present, no additional regulatory action is needed over and above the planned interventions at Sizewell B Power Station.
