Intermediate level waste (ILW)

Intermediate level waste (ILW) contains higher amounts of radioactivity and some require shielding. It typically comprises resins, chemical sludges and metal fuel cladding, as well as contaminated materials from reactor decommissioning. It may be solidified in concrete or bitumen for disposal. Generally, short-lived waste (mainly from reactors) is buried in a shallow repository, whereas long-lived waste, for example waste from fuel repro­cessing, could be buried deep underground.
