DG-1349 Revision 1, Page 20 GLOSSARY decommission As stated in 10 CFR 50.2, to remove a facility or site safely from service and reduce residual radioactivity to a level that permits (1) release of the property for unrestricted use and termination of the license; or (2) release of the property under restricted conditions and termination of the license. major decommissioning activity As stated in 10 CFR 50.2, any activity that results in permanent removal of major radioactive components, permanently modifies the structure of the containment, or results in dismantling components for shipment containing greater than class C waste. major radioactive components As stated in 10 CFR 50.2, the reactor vessel and internals, steam generators, pressurizers, large-bore reactor coolant system piping, and other large components that are radioactive to a comparable degree. DECON The equipment, structures, and portions of the facility and site that contain radioactive contaminants that are promptly removed or decontaminated to a level that permits termination of the license shortly after cessation of operations. SAFSTOR A facility that is placed in a safe, stable condition and maintained in that state (safe storage) until it is subsequently decontaminated and dismantled to levels that permit license termination. During SAFSTOR, a facility is left intact, but the fuel has been removed from the reactor vessel, and radioactive liquids have been drained from systems and components and then processed. Radioactive decay occurs during the SAFSTOR period, thus reducing the quantity of contaminated and radioactive material that must be disposed of during decontamination and dismantlement. The definition of SAFSTOR also includes the decontamination and
