This was a planned visit in pursuance of ONR's plan of compliance inspection for Chapelcross.
The main activity at this visit was the Annual Review of Safety, which takes the same form at each Magnox Ltd site. The ONR team makes a general inspection of the site, then meets the site's lead team in a formal meeting to discuss the site's safety performance in the preceding year and its objectives for the coming year. The meeting is based on a large, standardised set of reports covering all the safety-related functions and activities on the site.
I made planned inspections of the licensee's compliance with two of the conditions attached to its nuclear site licence: Licence Condition 4-Restrictions on nuclear matter on the site, and Licence Condition 36-Organisational capability.
I had a discussion about the next phase of the decommissioning of the 16 heat exchangers that are attached around the reactors.
In these and other discussions the outcomes of actions previously placed were reviewed, and the actions closed where possible; new actions were also placed.
I did not carry out a safety system inspection.
The licensee's safety record in the year preceding the Annual Review of Safety was good, as was its preparation for and conduct of this meeting.
I found the licensee's compliance with both LC4 and LC36 adequate. I have required the licensee to revise part of the arrangements it has made under LC4 for bringing nuclear matter onto the site. The safety significance of this revision is currently low, however, as nuclear matter has not been brought onto the site for several years. I judged that the site has adjusted well to the major organisational change it made in September 2013, after the reactors had been defuelled.
I found no issues that significantly affect nuclear safety, or that require me to take further regulatory action.
