Disposal 1
Disposal 1 : (1) Emplacement of waste in an appropriate facility without the intention of retrieval. In some States, the term disposal is used to include discharges of effluents to the environment. In some States, the term disposal is used administratively in such a way as to include, for example, incineration of waste or the transfer of waste between operators. In Agency publications, disposal should be used only in accordance with the more restrictive definition given above. In many cases, the only element of this definition that is important is the distinction between disposal (with no intent to retrieve) and storage (with intent to retrieve). In such cases, a definition is not necessary; the distinction can be made in the form of a footnote at the first use of the term disposal or storage (e.g. "The use of the term 'disposal' indicates that there is no intention to retrieve the waste. If retrieval of the waste at any time in the future is intended, the term 'storage' is used"). The term disposal implies that retrieval is not intended; it does not mean that retrieval is not possible. For storage in a combined storage and disposal facility, for which a decision may be made at the time of its closure whether to remove the waste stored the during operation of the storage facility or to dispose of it by encasing it in concrete, the question of intention of retrieval may be left open until the time of closure of the facility. Contrasted with storage. Direct Disposal: Disposal of spent fuel as waste. Geological Disposal: Disposal in a geological repository. See: also repository. The term intermediate disposal is sometimes used for the disposal of low and intermediate level waste (LILW) (e.g. in boreholes - i.e. between near surface disposal and geological disposal). Near Surface Disposal: Disposal, with or without engineered barriers, in a near surface repository. Sub-Seabed Disposal: Disposal in a geological repository in the rock underlying the seabed. (2) The emplacement of spent fuel or radioactive waste in an appropriate facility without the intention of retrieval. (3) The act or process of getting rid of waste, without the intention of retrieval. The terms deep sea disposal and seabed disposal do not strictly satisfy definition (1) or (2), but are consistent with the everyday meaning of disposal and are used as such. Deep Sea Disposal: Disposal of waste packaged in containers on the deep ocean floor. The commonly used, but informal, term 'sea dumping' should not be used in Agency publications. As practised until 1982 in accordance with the requirements of the London Convention 1972. Seabed Disposal: Emplacement of waste packaged in suitable containers at some depth into the sedimentary layers of the deep ocean floor. This may be achieved by direct emplacement, or by placing the waste in specially designed 'penetrators' which, when dropped into the sea, embed themselves in the sediment
