Major Milestone Reached on LLWR Decommissioning Project

A major milestone has been reached on the LLWR PCM Decommissioning and Demolition project with the transition of a magazine to C2 radiological classification.

Magazine 10 is the first of four remaining magazines scheduled to be fully decommissioned and it is now possible to enter the magazine without any respiratory protection for the first time since the magazines were filled with PCM (plutonium contaminated material) waste over 20 years ago. This marks a major achievement for the project, which NSG has been delivering as part of an integrated team on the site for the last five and a half years. In this time, the facility has been transitioned from C5, the highest contamination-controlled area classification, to C3 and now finally C2, where only a pair of overshoes is required to enter in addition to the standard ‘Site Basics’ clothing.

Gareth Wilson, NSG’s Project Manager at LLWR, commented:

The decommissioning activities undertaken by the project team to achieve this milestone have been vast and included some significant challenges. A number of the tasks have involved closely managing significant risks in terms of conventional safety whilst working in high hazard contamination-controlled areas. The team have worked vigilantly to complete all tasks safely and have delivered all the decommissioning scope without a single lost time accident.
