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
