[en] The Fuel Supply Shutdown (FSS) Facility safety bases was completely revised to become 10CFR-830 compliant and to reflect the current mission and reduced risks associated with the operation of the facility, due to reduced radioactive material inventory. This Technical Safety Requirement (TSR) revision includes requirements to ensure the hazards and accident scenarios identified in the new safety basis are adequately controlled. The TSR controls are limited to Administrative Controls (ACs), which have been developed to either protect the assumptions in the accident scenarios or further reduce the scenario consequences. Design features have also been designated to further reduce the dose consequences of accident scenarios and to reduce the probability of a criticality event. A Bases section was added to further describe the reasons for several of the ACs to provide operations and engineering staff with the necessary information to maintain operation of the FSS Facility within the safety envelope and to ensure that any future changes to these requirements will not affect their original intent or purpose
