This inspection was one of a series of planned inspections for 2019/20, which are informed by the ONR Decommissioning Fuel and Waste (DFW) sub-division strategy.
This inspection examined the adequacy of Magnox Limited’s (ML) arrangements and their implementation on the Wylfa site for compliance with three Licence Conditions (LC): LC 10 (Training), LC24 (Operating Instructions) and LC28 (Examination, Inspection, Maintenance and Testing). I also held meetings concerning Wylfa’s planned emergency exercises Dynamo 2019 and Bangor 2019; and with the site’s safety representatives.
For LC 10, I focussed on the training of staff currently involved in activities leading to the removal of all fuel from the site, including those delivering the fuel free verification process. For LC24, I focussed on the operating instructions currently being used by those undertaking defuelling and fuel free verification activities. For LC 28, I focussed on the examination, inspection, maintenance and testing of equipment in the plant maintenance schedule associated with irradiated fuel handling equipment.
I met with licensee’s staff to discuss Wylfa’s on-going exercise programme intended to produce teams that can manage emergencies on the site following its post-defuelling transition to reduced scope emergency arrangements.
I also met a site safety representative.
Based on the evidence examined it is my judgement that ML is effectively implementing arrangements for complying with LC 10, LC 24 and LC 28 at Wylfa. I identified areas of good practice and some areas where ML could improve.
I identified no matters that in my opinion could adversely affect nuclear safety. My findings were shared with and accepted by the licensee.
