More than 90 percent of the radioactive waste in the UK today (by volume) can already be safely disposed of in suitably authorised and permitted landfill sites, or in the Low Level Waste Repository (LLWR) in Cumbria. The rest of the waste is more radioactive and will stay that way for longer, and so needs a safe, secure, long-term solution. At RWM, we’re going ahead with a plan to safely and securely dispose of this waste in a Geological Disposal Facility (GDF). An important part of my team’s role is regularly updating our estimate of how much waste a GDF will need to accommodate. We call this estimate the Inventory for Geological Disposal (IGD). It sounds like a job that’s all about the numbers, but I actually spend a fair amount of time out and about dealing with people, helping to improve our data and how we communicate about it. To estimate how much waste will need to go in a GDF, first we need to know how much waste already exists in the UK today. The Nuclear Decommissioning Authority are a big help with this – they take stock of the UK’s radioactive waste every three years and report their findings in the UK Radioactive Waste Inventory (UKRWI). This is one of the world’s most comprehensive inventories. The level of detail is incredible. It gives me and my team a really solid foundation to build on.

Scientists have developed a radiation-resistant material that makes it safer and cheaper to capture radioactive off gases that are generated during the recycling of spent nuclear fuel and the operation of some advanced reactors. Current technologies are expensive, and this new material makes it more efficient to capture noble gasses like xenon and krypton, which are byproducts of nuclear fission. Plus, captured non-radioactive xenon can be repurposed for use in medicine and commercial lighting.
