Planned intervention at Magnox Ltd’s Wylfa licensed site, undertaken as part of a series of planned interventions outlined in the ONR Integrated Intervention Strategy (IIS) Plan Wylfa Power Station 2015/2016.
Planned compliance inspection of Licence Conditions 11 was carried out through the inspection of a shift exercise.
In addition to the inspection identified above a joint regulatory liaison meeting was attended to monitor progress with current activities and maintain awareness of any matters of shared regulatory interest with environmental regulators and other ONR regulatory functions.
No safety system based inspections were undertaken during this intervention.
The focus of this emergency arrangements intervention was to sample how Wylfa train, coach and develop emergency role personnel and was delivered through observation of the delivery of a shift exercise. Overall, the exercise provided a clear demonstration of Magnox Ltd’s approach to training through exercises at Wylfa and was well controlled ensuring it delivered key objectives. Based on the evidence from this intervention it is concluded that arrangements and subsequent implementation appear adequate.
The joint regulatory liaison meeting is held quarterly and coincidentally with the quarterly defueling transition oversight meeting. The meeting focuses on reviewing areas of shared regulatory and operational interest with a view to ensuring common understanding and expectations across all organisations to provide successful outcomes. For each of the topics covered suitable responses by either Magnox Ltd or ONR were identified to progress matters towards adequate conclusions.
From the information obtained and evidence gathered during this intervention, I do not believe there are any matters identified that have a significant negative effect on the system integrity and there were no issues identified that were considered to adversely affect nuclear safety.
