Planned intervention at Winfrith

Executive summary

Purpose of Intervention

This inspection on the Winfrith licensed site was undertaken as part of a programme of planned interventions as outlined in the site inspection plan for 2017/18, an additional reactive unplanned inspection of Licence Condition (LC) 12 was also undertaken.

Interventions Carried Out by ONR

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

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable.

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

I found that the licensee was able to demonstrate compliance through its written arrangements with LC 4 and LC 5 from the sample of arrangements inspected and the operations observed during the inspection.

I found that the licensee was able to demonstrate compliance through its written arrangements with LC 9 from the sample of arrangements inspected and the induction training I attended prior to the inspection.

I found that the licensee was unable to demonstrate compliance with its own written arrangements for LC 12, as the management arrangements used by the Licensee to maintain oversight of the management of SQEP were not adequately used. I however received verbal assurances from the Licensee that only SQEP perform any duties which may affect safety and asked that additional written evidence and assurance be provided. I will be seeking improvements in the Licensee's management arrangements (and supporting tools) which provide the Licensee with oversight of the management of SQEP so that only SQEP can perform duties which may affect safety

Conclusion of Intervention

In my opinion the Licensee's arrangements for compliance with LC 4, 5 and 9 were adequate from the sample of arrangements inspected and the operations observed during the inspection. With respect to compliance with LC 12 I will seek improvements in the management arrangements to ensure the Licensee has adequate oversight of the management of SQEP so that only SQEP perform any duties which may affect safety.
