Executive summary

Purpose of Intervention

In accordance with the Office for Nuclear Regulation’s (ONR’s) Hinkley Point C (HPC) Construction Inspection Plan, ONR performs a series of planned compliance inspections of identified licence conditions (LC) and other applicable legislation, to ensure that NNB Generation Company (HPC) Ltd (NNB GenCo), is meeting its legal requirements

Interventions Carried Out by ONR

LC17 requires a licensee to make and implement adequate quality management arrangements in respect of all matters which may affect safety.

ONR carried out the following LC17 intervention:

  • A one-day intervention to confirm that the licensees current management system arrangements and interface with the MEH Alliance (MEHA) are adequately implemented, effective and integrated.

The following guidance was used in this intervention:

  • NS-INSP-GD-006: LC 6 – Documents, records, authorities, and certificates
  • NS-TAST-GD-033: Duty Holder Management of Records
  • NS-INSP-GD-017: LC 17 – Management Systems
  • NS-TAST-GD-049: Licensee use of Contractors and Intelligent Customer Capability
  • NS-TAST-GD-077: Procurement of Nuclear Safety Related Items or Services

Explanation of Judgement if Safety System Not Judged to be Adequate

N/A as this was not a safety systems inspection.

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

I found that NNB GenCo (HPC) had effectively implemented its management system arrangements in relation to mechanical, electrical and heating, ventilation and air conditioning (MEH) activities.  Notable progress has been made in the development of the MEHA process guidance manual and construction site installation process manual end-to-end process map. I found clear evidence of effective collaborative working between quality leads of different dutyholder organisations.

I undertook a walkdown of relevant MEH installation areas and reviewed evidence of records associated with installed items and equipment. I found that the work was adequately controlled and that records had been managed appropriately for the current scale of installation activities. The challenge in relation to scalability and integration of data management tools is recognised by the dutyholders and the project is further developing the necessary tools.

During the site walkdown and subsequent review of records a number of minor areas for improvement were identified and action was taken by the dutyholder to rectify.

Conclusion of Intervention

I judge that on the basis of the evidence sampled the licensee has adequately implemented management system arrangements for control of installation activities and associated management of records. On this basis I judge that an inspection rating of Green (no formal action) is merited for LC17. Further development of supporting data management tools is planned and adequacy of arrangements will be subject to review through the NNB GenCo Hold Point process. ONR will monitor progress in this area which will be the subject of future planned interventions.
