High Level Waste (HLW) typically arises in liquid form, generated as a by-product during the reprocessing of spent fuel from nuclear reactors. The liquid HLW is mixed with crushed glass in a furnace to produce a molten product.
What is intermediate level waste?
Intermediate Level Waste (ILW) may need treatment before being packaged for storage and disposal. Treatment may involve super-compacting, cutting or drying. Radioactive Waste Management (a subsidiary of the NDA) is responsible for preparing standards and specifications for ILW packages, and for providing advice to waste producers on the packaging of ILW. For most ILW, packaging involves placing the waste into a suitable container and immobilising the waste in cement-based materials. Typical packages include 500 litre stainless steel drums or 3m 3 stainless steel boxes. Larger items are packed into higher capacity stainless steel, concrete boxes or ductile cast iron containers. The packages ensure that the ILW can be safely stored, transported and disposed of.
