Hinkley Point C - To perform combined intervention on NNB HPC project on the subject of quality

Executive summary

Purpose of Intervention

This was an intervention carried out on EDF Energy Nuclear New Build Generating Company Hinkley Point ‘C’ (NNB HPC) of project management systems including the newly formed quality and learning group. Management systems and quality management arrangements are identified in licence condition 17 (LC 17). The intervention objective was to assess the adequacy of quality and learning processes and the wider project management systems for this stage of the project and to obtain objective evidence of compliance.

Interventions Carried Out by ONR

This intervention was carried at the NNB HPC delivery command centre (DCC) Bridge Water House (BWH) in Bristol on 16th and 17th May 2018 and followed a structured  agenda, see TRIM:2018/0185652, which covers the project management systems and specifically the quality function.

This intervention was office based with objective evidence being provided from BWH and the construction site when applicable; never the less I consider that a joint inspection at the construction site may be necessary to sample the effectiveness of  the implementation of the Integrated Management Systems (IMS).

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

 The following positive Items were noted during this intervention;

The  following areas have been identified as requiring improvement;

My judgement is that overall the rating for this work stream DEV 3, quality, remains at AMBER. To achieve green the following actions are pertinent;

Management action is required to address the shortfalls identified in section 5 above.

Conclusion of Intervention

The intervention achieved its purpose and efficiently delivered to the agenda. All staff presented an understanding of their roles, responsibilities and core processes.

I have concluded that that the management systems and quality management arrangements presented are compliant with licence condition 17 ‘Management Systems’.  However, I have rated this work stream as Amber due to shortfalls and f issues identified, which will undermine NNB’s arrangements if not addressed in a timely manner.

I have raised two regulatory issues, one on resource plan and the other on work control documents identified as being outside the integrated management system. I consider that with the correct application of these and the identified planned actions, NNB HPC will gain the required improvements.

I have identified that a joint inspection at the construction site will be required to gain objective evidence of management systems implementation.
