Work progresses for disposal of radioactive waste in the UK
A protective layer is being placed over historic trenches at a site in West Cumbria, UK, ahead of permanent disposal of radioactive waste.

Nuclear Waste Services, which manages the disposal of the UK’s low-level radioactive waste, is working on the final capping of legacy disposal trenches and vaults
© Nuclear Waste ServicesKnown as the southern trench interim membrane project (STIM), the protective layer will remain in place for up to 100 years over legacy disposal trenches at the low-level waste repository (LLWR) site.
This represents a milestone in capping operations for Nuclear Waste Services (NWS), with the final closure of the repository expected in 2135.
STIM will replace the current interim membrane over part of the legacy disposal trenches.
Direct Rail Services trains will make the journey from Shap quarry to the Repository to deliver over 750 tonnes of material – the equivalent of 36 HGVs.
The first deliveries will arrive between February and March 2025, with eight deliveries expected each week.
