Nuclear material in concentrations or chemical forms which do not permit economic recovery and which is designated for disposal. Disposal methods depend on the radioactivity level of the waste and normally include conditioning of the waste into a suitable form, e.g., vitrification of high level liquid waste or mixing of hulls and medium level waste with cement. For safeguarded nuclear material contained in waste, arrangements for termination of safeguards should be agreed between the State and the IAEA before disposal.
