y consists of putting the facility in a state of protective storage. In general, the facility may be left intact except that all fuel assemblies and the radioactive fluids .and waste should be removed from the site. Adequate radiation monitoring, environmental surveil lance, and appropriate security procedures should be established under a possession-only license to ensure that the health and safety of the public is not endangered. b. In-Place Entombment. In-place entombment con sists of sealing all the remaining highly radioactive or contaminated components (e.g., the pressure vessel and reactor internals) within a structure integral with the biological shield after having all fuel assemblies, radio active fluids and wastes, and certain selected com ponents shipped offsite. The structure should provide integrity over the period of time in which significant quantities (greater than Table I levels) of radioactivity remain with the material in the entombment. An appropriate and continuing surveillance program should be established under a possession-only license. c. Removal of Radioactive Components and Dis mantling. All fuel assemblies, radioactive fluids and waste, and other materials having activities above ac cepted unrestricted activity levels (Table I) should be removed from the site. The facility owner may then have unrestricted use of the site with no requirement for a license. If the facility owner so desires, the remainder of the reactor facility may be dismantled and all vestiges removed and disposed of. d. Conversion to a New Nuclear System or a Fossil Fuel System. This alternative, which applies only to nuclear power plants, utilizes the existing turbine system with a new steam supply system. The original nuclear steam supply system should be separated from the electric generating system and disposed of in accordance with one of the previous three retirement alternatives. 3.
