SAFSTOR is a nuclear decommissioning method in which a nuclear power plant or facility governed by the United States Nuclear Regulatory Commission , is "placed and maintained in a condition that allows the facility to be safely stored and subsequently decontaminated (deferred decontamination) to levels that permit release for unrestricted use" .
4-445: During SAFSTOR the de-fuelled plant is monitored before complete decontamination and dismantling of the site, to a condition where nuclear licensing is no longer required. The decommissioning must be completed within 60 years of the plant ceasing operations. During the storage interval, some of the radioactive contaminants of the reactor and power plant will decay, which will reduce the quantity of radioactive material to be removed during
8-658: A retired nuclear plant may be chosen based on availability of decommissioning funds, operation of other reactors at the same site, or availability of waste disposal facilities. In 2004, 11 reactors were planned for DECON and 9 for SAFSTOR. In 2008, 14 shutdown commercial power reactors were planned for or had completed DECON, 11 were in SAFSTOR, 3 were in ENTOMB and Three Mile Island unit 2 was defuelled and will be decontaminated when Unit 1 ceases operation.

12-475: Is the enclosure of contaminated parts of the plant in a permanent layer of concrete. Mixtures of options may be used, for example, immediate removal of steam turbine components and condensers, and SAFSTOR for the more heavily radioactive containment vessel. Since NRC requires decommissioning to be completed within 60 years, ENTOMB is not usually chosen since not all activity will have decayed to an unregulated background level in that time. Decommissioning options for
16-471: The final decontamination phase. Different sub-levels of SAFSTOR are recognized, which vary in the type of activity and monitoring required. All varieties of SAFSTOR require positive action to decontaminate the site at the end of the storage period. The other options set by the NRC are nuclear decommissioning which is immediate dismantling of the plant and remediation of the site, and nuclear entombment which
