Key findings, inspector’s opinions and reasons for judgement made

Responses to questioning were forthcoming, constructive, and provided confidence that the civil engineering works associated with the unit 1 and 2 fuel buildings (HK), where sampled, were being adequately managed with due consideration of the risks involved.

A small number of minor observations were made.

Overall, I was satisfied with the adequacy of NNB Generation Company (HPC) Ltd’s (NNB GenCo) ongoing arrangements associated with the construction of HK.

On the basis of the evidence sampled, and in recognition of progress to date, I was satisfied that the arrangements in place comply with Licence Condition (LC) 19.


My overall judgement for the inspection concludes that, based on the evidence sampled, I was satisfied that arrangements in place address the key risks associated with the Unit 1 and 2 Fuel Buildings (HK). Furthermore, those arrangements are under implementation and are consistent with relevant good practice.
