Major Milestone Achieved at LLWR


A major skyline change is under way at the Low Level Waste Repository (LLWR) in West Cumbria. As the preferred partner on the PCM Decommissioning and Demolition contract and in collaboration with LLW Repository Ltd and KDC, the Drigg-based NSG site team have safely completed the demolition of the Magazine 4 Retrieval Facility (MRF), a fixture at the site since the 1990s.

Magazine 4 is the first of five remaining MRFs to be demolished, with soil removed from the top of the magazine structure, erection of an environmental barrier at the magazine entrance and the removal off site of all remaining waste. The team have proven the demolition method for the MRF and the method will be reviewed as part of the post-project review to identify any improvements and efficiencies for future demolition phases.

MRFs are purpose-built engineered facilities, constructed to allow the retrieval of plutonium contaminated materials (PCM) from magazines before decommissioning and demolition could begin. All remaining magazines on the site will be demolished, in time, to make way for future vaults.
