Technology, safety and costs of decommissioning reference independent spent-fuel-storage installations. [Drywell, silo, vault, cask, water basin]

OSTI ID:7036102
Safety and cost information is developed for the conceptual decommissioning of five different types of independent spent-fuel-storage installations (ISFSIs), each of which is being given consideration for long-term storage of spent nuclear fuel in the United States. These include one water basin-type ISFSI (wet) and four dry ISFSIs (drywell, silo, vault, and cask). Three decommissioning alternatives are studied to obtain comparisons between costs (in 1981 dollars), occupational radiation doses, and potential radiation doses to the public. The alternatives considered are: DECON (immediate decontamination), SAFSTOR (safe storage followed by deferred decontamination, and ENTOMB (entombment). Effects of storage size, colocation at a reactor site and elimination of fuel encapsulation upon decontamination are examined to provide potential owners with information applicable to most proposed ISFSIs. 7 tables.
