Hinkley Point B - Planned compliance inspections

Executive summary

Purpose of Intervention

The purpose of this intervention was to undertake licence condition (LC) compliance and Radioactive Materials Transport inspections of EDF Energy Nuclear Generation Ltd.’s (NGL’s) Hinkley Point B Power Station. This was undertaken as part of the planned intervention strategy for the Operating Facilities Division (OFD) of the Office for Nuclear Regulation (ONR).

The intervention was carried out by the nominated site inspector jointly with the Environment Agency, for licence compliance, and with a specialist Transport Inspector for Radioactive Materials Transport.

Interventions Carried Out by ONR

I, the nominated site inspector performed an inspection to evaluate NGL’s compliance with the following nuclear site licence condition (LCs) and legislation which are applicable provisions of the Energy Act 2013:

Whilst on site, I also undertook the following engagement activities with the licensee;

The intervention was performed in line with ONR's guidance requirements (as described in our technical inspection guides) in the areas inspected.

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable – no system based inspections were completed during this intervention.

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

For LC22, I sampled the licensee’s arrangements for controlling modifications to existing plant. I am satisfied that the licensee’s arrangements and their implementation in compliance with LC22 are suitable and sufficient. Two formal actions were raised, one relating to the identification and tracking of implementation actions arising from modifications and one relating to control of changes to maintenance documentation. I am satisfied that an IIS rating of green against LC22 is merited.

For Radioactive Material Transport the specialist inspector sampled the licensee’s arrangements for management systems, package maintenance and operations, preparation for consignment and training and competence. I am satisfied that the arrangements and their implementation in compliance with Carriage of Dangerous Goods (CDG) and Use of Transportable Pressure Equipment Regulations 2009 (as amended) are suitable and sufficient. No formal actions were considered necessary. I am satisfied that an IIS rating of green against Carriage of Dangerous Goods (CDG) and Use of Transportable Pressure Equipment Regulations 2009 (as amended)  is merited.  

Conclusion of Intervention

There were no findings from this inspection that could significantly undermine nuclear safety.  At present, no additional regulatory action is needed over and above the planned interventions of Hinkley Point B power station as set out in the IIS, which will continue as planned.
