Application of bridging methods for standard HTGR [High-Temperature Gas-Cooled Reactor] licensing bases

A review of the bridging methods is accomplished by providing an application of the process to the standard HTGR. A representative PRA, of limited range, is used in the process, and representative deterministic licensing bases are obtained. The PRA is presented as a risk plot, and the characteristics of the events and the equipment in the PRA are used in the bridging application. Representative licensing basis events are identified consisting of anticipated operational occurrences, design basis events, and emergency planning basis events. Representative safety-related functions and safety-related structures, systems and components are identified. The licensing basis events and safety-related functions and equipment are representative of the deterministic licensing bases that will be included in the PSID and SARs. A response is requested from NRC on the acceptability of the application of the method, considering the range of the representative PRA presented
