Inspection of Licence Condition 17 focused on Nuclear Safety Culture Development at site

Executive summary

Purpose of Intervention

The purpose of this ONR intervention was to undertake a planned inspection at NNB Generation Company (HPC) Ltd (NNB GenCo (HPC)), Hinkley Point C (HPC), in accordance with ONR’s Intervention Plan for the regulation of Hinkley Point C in 2018/19.

This planned licence condition inspection was carried out by ONR organisational capability specialists to assess the progress in nuclear safety culture activities at NNB GenCo (HPC)’s Site Command Centre, and thus to make a judgement on NNB GenCo (HPC)’s compliance with Licence Condition 17.

Interventions Carried Out by ONR

Licence Condition 17 (LC17) requires that the licensee shall: “establish and implement management systems which give due priority to safety” [and]: “within its management systems, make and implement adequate quality management arrangements in respect of all matters which may affect safety.”

The inspection, which comprised of discussions with NNB GenCo (HPC)’s staff and examination of NNB GenCo (HPC)’s documentation, focused on the implementation of the Project Culture Strategy and nuclear safety culture related site activities.

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable; this was not a Safety System inspection.

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

The ONR inspectors consider the developments of the nuclear safety culture at NNB GenCo (HPC) to be good in many areas. For instance, there is evidence of Project Culture Strategy, underpinned with an Implementation plan, which has good leadership support, allocated budget, and which is delivered through the year. Notable outputs from this Implementation plan are Leadership Lanyard, Project Culture Survey and internal communication. There is also evidence of the Site Construction Director’s visible and trust inspiring leadership, long term commitment and approachability.

In addition, key nuclear safety culture projects like Behaviours and Values for Success, Engaged Leadership, Lean and Simple, and Shared Schedule show clear long term commitment of NNB GenCo (HPC)’s leadership.

The interviews with the HPC workforce showed good professional attitude towards safety and quality. The issues mentioned during the interview were fed back to NNB GenCo (HPC) representatives and will be used as intelligence for further regulatory interventions in cooperation with the nominated site inspector.

Conclusion of Intervention

On the basis of the evidence gathered during this inspection, the ONR inspectors judged the compliance with licence condition 17 as Green (No Formal Action).

The inspection findings were shared with, and accepted by the licensee.
