Magnox Ltd Harwell - Compliance Inspection

Executive summary

Purpose of Intervention

This inspection on the Harwell licensed site was undertaken as part of a programme of planned interventions as outlined in the site inspection plan for 2017/18.

Interventions Carried Out by ONR

During this intervention, I carried out a compliance inspection against the following licence conditions:

During this intervention, ONR inspectors attended the licensee's annual review of safety, environment and security. The inspections comprised office-based examination of procedures and records and interviews with staff. I also held meetings to discuss a number of routine matters.

Explanation of Judgement if Safety System Not Judged to be Adequate

No safety system was inspected during this intervention.

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

In relation to LC22, my inspection of the licensee's arrangements for compliance to this licence condition considered the forthcoming decommissioning of the Steam Generating Heavy Water Reactor core. I consider that the licensee has suitable arrangements for compliance to this licence condition and thus far, the licensee has demonstrated that it is implementing its arrangements for controlling modifications to existing plant for this decommissioning project.

In relation to LC25, I inspected the licensee's arrangements to create and retain waste records. I consider that based on the evidence gained from this inspection, the licensee is creating adequate records that records of the amount and location of all radioactive waste processed, stored and despatched and has therefore met this licence condition. However the licensee has identified a shortcoming with its arrangements and I have requested that it take action to improve in this area.

ONR considered that during the annual review of safety, environment and security, the licensee had been sufficiently self-critical and had identified appropriate areas for improvement. ONR judged that the site is currently properly managed and in control of the hazards on site.

Conclusion of Intervention

From the evidence gathered during this intervention, I conclude that there are no matters that may impact significantly on nuclear safety.
