Storage 12
Storage 12 : The holding of radioactive sources, spent fuel or of radioactive waste in a facility that provides for their/its containment, with the intention of retrieval. Generalized from the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management, WS-R-2 and the Code of Conduct on the Safety and Security of Radioactive Sources. Storage is by definition an interim measure, and the term interim storage would therefore be appropriate only to refer to short term temporary storage when contrasting this with the longer term fate of the waste. Storage as defined above should not be described as interim storage. 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."). 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 disposal. Dry Storage: Storage in a gaseous environment, such as air or an inert gas. Dry storage facilities include facilities for the storage of spent fuel in casks, silos or vaults. Wet Storage: Storage in water or other liquid. The universal mode of wet storage consists in storing spent fuel assemblies or spent fuel elements in pools of water or other liquids, usually supported on racks or in baskets and/or in canisters that also contain liquid. The liquid in the pool surrounding the fuel provides for heat dissipation and radiation shielding, and the racks or other devices ensure a geometrical configuration that maintains sub-criticality
