I carried out a System Based Inspection (SBI) as part of a series of planned inspections at the Magnox Ltd (ML) Chapelcross (CHX) decommissioning site during 2020/21.
I carried out an SBI on CHX’s implementation of their LC10, 21, 22, 23, 24, 27, 28 and 34 arrangements for MAC & Cobalt ILW retrieval operations during December 2020. ONR inspectors also held an update meeting with the CHX Safety Representatives.
From the documentation examined and the areas inspected, I found that CHX’s implementation of its LC 10, 21, 22, 23, 24, 27, 28, and 34 arrangements was adequate and that the MAC & Cobalt retrievals safety system adequately fulfils the requirements of the safety case.
I judged that ML’s implementation of its LC10, 21, 22, 23, 24, 27, 28, and 34 arrangements for CHX MAC & Cobalt ILW retrievals as adequate in the areas inspected. I did not identify any significant regulatory concerns.
