The purpose of this intervention was to undertake Licence Condition (LC) compliance inspections at EDF Energy Nuclear Generation Ltd's (NGL's) Hunterston B power station, in line with the planned inspection programme contained in the Hunterston B Integrated Intervention Strategy (IIS) for 2016/17.

This intervention included compliance inspections against the following Licence Conditions:

I undertook a review of the station's progress against its existing regulatory issues. I also attended a monthly update meeting with the station Independent Nuclear Assurance (INA) evaluators.

Explanation of Judgement if Safety System Not Judged to be Adequate

Key Findings, Inspector's Opinions and Reasons for Judgements Made

In relation to LC 2, I:

In relation to LC 10, I:

In relation to LC 21, I:

The intervention was performed in line with ONR's guidance requirements (as described in our technical inspection guides) in the areas inspected.

Conclusion of Intervention

In relation to LC 2, I considered that an inspection rating of 'Green' is warranted on the basis that relevant good practice is generally being met, but with some minor shortfalls identified.

In relation to LC 10, I considered that an inspection rating of 'Green' is appropriate. This is on the basis that the arrangements for management and conduct of operations training are mature and align with internationally relevant standards. Re-accreditation by the INPO (Institute of Nuclear Power Operators) derived technical safety advisory board in March 2015 is further evidence that the operations training programmes are robust.

In relation to compliance with Licence Condition 21, I judge that an inspection rating of 'Green' is warranted on the basis that relevant good practice is generally being met, but with some minor administrative shortfalls identified.

There are no findings from this inspection that could significantly undermine nuclear safety.
