Radioactive waste
Types of radioactive waste - ILW
Intermediate Level Waste
- Exceeds 4 GBq/tonne of alpha activity or 12 GBq/tonne of beta/gamma (LLW) but lower heat and radioactivity output than HLW.
- Does not require consideration of heat to be taken into account with regards to storage design.
- The major components of ILW are metals, with smaller quantities of inorganic sludges, organic materials, cement and graphite. Principally materials that have been irradiated in a nuclear reactor and materials that have been used in the processing of radioactive materials. ILW is also produced during the decommissioning of facilities.
- Stored in shielded tanks, vaults or silos.
- Immobilised in cement.
