Licence condition 10, 12 and 26 compliance inspection

Executive summary

Purpose of intervention

The purpose of the intervention was to carry out planned compliance inspections as part of ONR’s integrated intervention strategy for Sizewell A.

Interventions Carried Out by ONR

I inspected compliance with Licence Condition (LC) 26 (control and supervision), LC 12 (duly authorised and other suitably qualified and experience personnel) and LC 10 (training).  During this inspection, I focussed on the licensee’s construction office.  The construction office is a relatively new organisation on site, and at the moment its responsibilities are limited to project work (specifically, it is not responsible for infrastructure or maintenance work, although some project work has been managed through the constriction office to prove the concept).  However, post-transition the intention of the site is to manage all work through the construction office, so I considered it timely to inspect the arrangements it has in place.

Explanation of Judgement if Safety System Not Judged to be Adequate


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

I consider compliance with LC 26 to be good.  The licensee has adequate controls for ensuring that there are sufficient safety provisions in place prior to the commencement of, and during, work that may affect safety.  The site engineers exercise appropriate supervision on behalf of the licensee.  Many of the details of the licensee’s arrangements I consider to be good practice, for example the pre-start meetings, the scrutiny of the contractor’s written instructions, the use of area plans for briefing and the turbine hall access control point

The licensee has good arrangements in place to ensure that both construction office staff, and contractors managed through the construction office, are suitably qualified and experienced and I therefore rated this inspection of LC 12 to be good.

The licensee has developed training for the implementation of the construction office, and aims to roll that training out across all interfacing disciplines (having already delivered it to operations and projects staff).   I therefore consider compliance with LC 10 to be adequate.

Conclusion of Intervention

I found no issues seriously affecting nuclear safety, or requiring further regulatory attention.
