Hinkley Point A - Licence Condition compliance inspection

Executive summary

Purpose of Intervention

I undertook this inspection to examine Magnox Ltd’s arrangements for managing people capability, competence and control, in respect of its nuclear and radiological operations at Hinkley Point A.  This was one of a series of planned inspections for 2018/19 the Hinkley Point A site in support of ONR’s Decommissioning Fuel and Waste sub-division strategy.  The inspection was carried out in conjunction with Magnox Ltd’s Internal Regulator for the Site.

Interventions Carried Out by ONR

I inspected Hinkley Point A’s compliance with the following Licence Conditions (LC):

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable.

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

I examined the licensee’s arrangements for managing organisational change and how these had been implemented at the site.  I also examined how the licensee ensures the suitable training of its staff.  I sampled evidence from a recent organisational change and a key waste retrieval project and we found that the licensee had adequate arrangements in place for managing and controlling change its organisational capability, and had implemented a systematic approach to training.

I also examined how the licensee ensures that all operations which may affect safety are only carried out under the control and supervision of trained persons appointed for that purpose.  I found that the licensee has adequate arrangements for ensuring operations are controlled and supervised, and that the level of control and supervision required is commensurate with the hazard.  I also found that operations are carried out in accordance with written instructions which ensure that that any operating rules are implemented.    I identified a shortfall in the arrangements for the review and amendment of operating instructions that has led to a number of infrequently used operating instructions not being reviewed in accordance with the review period established in the licensee’s arrangements however I found no evidence to indicate that nuclear safety was compromised as a result of this minor compliance shortfall.

Notwithstanding the minor compliance shortfall found in respect of the review period for a number of operating instructions, it is my judgement that overall the licensee is complying with the requirements of the licence conditions inspected.

Conclusion of Intervention

I provided feedback, jointly with the internal regulator, to the Site on the inspection findings at a close-out meeting with management representatives.  I requested the licensee to amend its arrangements to address the shortfall identified in the review of operating instructions; to identify those operating instructions which have not been reviewed in the required period, and to ensure these are reviewed in a systematic manner taking account of relative risk.
