Hinkley Point C - Planned Licence Compliance Inspection Covering LC09

Executive summary

Purpose of intervention

In accordance with the Office for Nuclear Regulation’s (ONR’s) Hinkley Point C Construction Intervention Strategy and underpinning Site Inspection task sheet, ONR performs a series of planned compliance inspections of identified licence conditions, to ensure that NNB Generation Company (HPC) Ltd (NNB GenCo), is proportionately and adequately developing and implementing its licence compliance arrangements commensurate to the current stage of the project.

This planned, licence condition inspection was carried out to assess NNB GenCo’s compliance with licence condition (LC) 09 – Instructions to Persons On Site, specifically assessing the adequacy of the off-site aspects of the induction process which are completed before access to the site is granted.

Interventions Carried Out by ONR

LC 09 requires NNB GenCo to “…ensure that every person authorised to be on the site receives adequate instructions (to the extent necessary having regard to the circumstances of that person being on the site) as regards the risks and hazards associated with the plant and its operation, the precautions to be observed in connection therewith and the action to be taken in the event of an accident or emergency on the site.”

I carried out this licence compliance inspection against licence condition 09 during the HPC induction process, utilising the following ONR inspection guidance:

  1. NS-TAST-GD-009 Revision 3 "Instructions to Persons On Site"

In addition I completed a site familiarisation visit to the Hinkley Point C construction site.

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

LC 09 Inspection

The induction process overall was well organised and followed what appeared to be a good structure which I consider provides evidence that NNB will be able to appropriately scale this training whilst maintaining consistency and quality.  

Overall I consider that the NNB induction process is providing adequate instructions to persons on site and providing a good basic understanding of the expected behaviours (including nuclear safety considerations) and potential risks at the Hinkley Point C construction site.

Conclusion of Intervention

On the basis of the evidence gathered during this inspection, I judge that an inspection rating of GREEN (No formal action) is appropriate for compliance against LC 09 – Instructions to persons on the site. This is because I found NNB   to be compliant with its legal duties with only minor areas for further improvement being identified.
