Hinkley Point B - Planned Intervention
- Site: Hinkley Point B
- IR number: 16-150
- Date: October 2016
- LC numbers: 11, 28
Purpose of Intervention
The purpose of this intervention was to undertake Licence Condition (LC) compliance inspections at EDF Energy Nuclear Generation Ltd’s (NGL’s) Hinkley Point B power station, in line with the planned inspection programme contained in the Hinkley Point B Integrated Intervention (IIS) plan for 2016/17
Interventions Carried Out by ONR
This intervention included compliance inspections against the following Licence Conditions:
- Licence Condition 11 – Emergency arrangements
- Licence Condition 28 – Examination, inspection, maintenance and testing
I also undertook a number of engagements with the licensee representatives, which covered the following topics;
- Quarterly review of the extant regulatory Issues
- Meeting with the Internal regulator
- Meeting with the Environment Agency (EA) Inspector
- Meeting with the employee safety representative
- Attendance at the Site Stakeholder Group (SSG) Meeting
Explanation of Judgement if Safety System Not Judged to be Adequate
Not applicable as no system inspection was undertaken during this intervention.
Key Findings, Inspector's Opinions and Reasons for Judgements Made
I undertook a planned intervention against LC 11, during which I:
- Conducted a plant walk down of the Emergency Control Centre (ECC), Access Control Point (ACP), Alternative Access Control Point (AACP) and the Tertiary Shutdown Store (TSS).
- Sampled the licensee’s procedures, equipment and the provision for adequate maintenance of emergency equipment.
- Reviewed the station’s progress towards achieving an adequate response capability to a beyond design basis accident (BDBA) with respect to its emergency arrangements - this was conducted against Hinkley Point B site specific capability map.
- Based on my observations during the walk down of the facilities, equipment and inspection of licensee’s procedures, I am content that licensee’s arrangements are suitable and sufficient with respect to compliance against LC 11.
I undertook a planned intervention against LC 28, during which I:
- Reviewed licensee’s arrangements for derivation of maintenance activities from the safety case and identification of these requirements within the Plant Maintenance Schedule (PMS).
- Reviewed the licensee’s process for managing maintenance of safety systems, tracking the periodicity of maintenance and the extant arrangements for extending the maintenance period, where relevant.
- Sampled the PMS activities for evidence to gain regulatory confidence that examination, maintenance, inspection and testing is delivered in accordance with the requirements laid down within the extant safety case.
- Overall, I am satisfied that the licensee’s arrangements for the delivery of examination, maintenance, inspection and testing meet the requirements of the safety case, and thus, adequately demonstrate compliance against the licence condition 28.
This intervention was performed in line with ONR’s guidance requirements (as described in our technical inspection guides, which can be found at ) in the areas inspected.
Conclusion of Intervention
In relation to LC 11, I judged that an IIS rating of ‘Green’ is merited on the basis that the station continues to exhibit a strong emergency preparedness and response capability in accordance with the requirements under LC 11.
In relation to LC28, I am satisfied that the licensee’s arrangements under licence condition 28 are suitable and sufficient. Moreover, the licensee’s arrangements for pro-active monitoring and management of the Plant Maintenance Schedule are suitably robust. I therefore, consider an IIS rating of “green” to be merited.
There are no findings from this inspection that could significantly undermine nuclear safety
