Office for Nuclear Regulation

Planned Topic Area inspection of LC 13, 14 and 17

Executive summary

Purpose of Intervention

This compliance inspection on the Magnox Ltd Harwell licensed nuclear site was undertaken as part of a programme of planned inspections as outlined in the Magnox southern sites’ inspection plan for 2018/19.  The scope of the inspection is aligned to the ONR Decommissioning, Fuel and Waste strategy and focussed on safety documentation, internal challenge and management systems as an inspection topic area within the strategy.  

Interventions Carried Out by ONR

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

I sought to gain evidence that:

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable.

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

The licensee was able to demonstrate through its written arrangements; from the sample of arrangements inspected; and the staff interviewed during the inspection that it complied with the requirements of LCs 13, 14 and 17.

It is my opinion that from the safety documentation examined it was appropriately categorised and that an appropriately conservative approach to safety was being taken by raising the categorisation clearance level and seeking advice from the Nuclear Safety Committee.

In forming my opinion I utilised information gained during previous interventions conducted by the ONR Magnox Ltd corporate inspector, by myself during safety case focussed inspections such as system based inspections and operational standards inspections and my observations of the conduct of the internal regulatory function. 

Conclusion of Intervention

In my opinion the Licensee's arrangements for compliance with LC 13, 14 and 17 were adequate from the sample of arrangements inspected and the staff interview during the inspection.  I therefore conclude that there are no matters that may impact significantly on nuclear safety.
