  • Site: Hinkley Point C
  • Inspection ID: 51629
  • Date: July 2022
  • LC numbers: 6

Executive summary

Purpose of inspection

This was a site based intervention to gain assurance that quality records support ongoing site installation activities and that information technology (IT) systems have been implemented to support this, focusing on the mechanical, electrical and heating, ventilation and air-conditioning (MEH) Alliance.

Subjects(s) of inspection

The following actives were the subject of this inspection:

  • Licence Condition 6 – Documents, records, authorities and certificates (Rating – Green)

Key findings

NNB Generation Company (HPC) Limited (NNB GenCo) was able to demonstrate that quality records are being produced for the ongoing site installation activities that were sampled for the reactor containment liner dome of unit 1 (dome 1). The containment heat removal system (EVU) works currently being carried out in dome 1 by the MEH Alliance includes weldingofthe supports and pipework. Sample records in relation to the EVU work were retrieved in a timely manner and were found to be adequate, although some observations have been made which require clarification.

IT systems are in place to support the production of quality records; however, there are planned improvements to further digitise solutions. This includes the roll out of the MEH Joint Venture (JV) data lake by Q4 2022 to allow the exchange of data between the various MEH JV IT systems and HPC and the roll out of portable devices to capture digitised information at the point of performance.

Improvements have been made since a previous inspection where there was a delay in retrieving records. This includes the development of aninformation recovery platform to improve retrievability which was demonstrated during the intervention.

Judgement made

Based on current relevant good practice, the work activities currently being undertaken and the evidence provided it was agreed that this intervention was rated green.

ONR will continue its focus on the scalability of the arrangements as the work and resources ramps up in 2023.
