Planned Licence Condition compliance inspections: LC 10, 12, 26, 28 and 36

Executive summary

Purpose of Intervention

This inspection was one of a series of planned inspections for 2020/21, which are informed by the ONR Decommissioning Fuel and Waste (DFW) sub-division strategy.   

Interventions Carried Out by ONR

This inspection examined the adequacy of Magnox Limited’s (ML) arrangements and their implementation on the Wylfa site, against the background of returning from a Covid-19 pause period, for compliance with Licence Conditions (LC): LC 10 (Training), LC 12 (Duly Authorised and other Suitably Qualified and Experienced Persons), LC 26 (Control and supervision of operations), LC 28 (Examination, Inspection, Maintenance and Testing) and LC 36 (Organisational Capability).

I also completed a walk-down of the Wylfa reactor equipment building with a Wylfa safety representative; and discussed with the site integration manager and head of maintenance the impact of the site pause on Wylfa’s planned activities through to the end of 2021.

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable.

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

Based on the evidence examined it is my judgement that ML is effectively implementing arrangements for complying with LC 10, 12, 26, 28 and 36 at Wylfa.    

Conclusion of Intervention

I identified no matters that in my opinion could adversely affect nuclear safety.  My findings were shared with and accepted by the licensee.
