ENCLOSURE 1 LIST OF REVISED REQUIRED ACTIONS TO CORRESPONDING PRA FUNCTIONS
{NOTE: This enclosure provides confirmation that the PRA models include the necessary scope of structures, systems, and components (SSCs) and their functions to address each proposed application of the RICT Program to the TS Required Actions.
Loss of Function Conditions, i.e. those TS conditions with insufficient TS operable equipment to meet the specified safety function of the system, are not to be included in the application.
The licensee lists each TS Required Action to which the RICT Program may be applied and, for each Required Action, describes the following:
the TS Required Action the corresponding SSC Each design basis function of the SSC how each design basis function is modeled in the PRA. If one of the design basis functions of an SSC or the SSC is not modeled in the PRA, describe any proposed surrogates and why the proposed surrogate adequately captures the configuration risk.
the success criteria used in the PRA model compared to the licensing basis criteria. The success criteria should include both train-level and component/parameter level.
Note that the above description should be at the level of the TS condition/TS Required Action (not at the LCO level only). If the TS condition/ TS Required action covers multiple SSCs or multiple design basis functions, such as in the case ESFAS Instrumentation or Containment Sprays, describe each one individually.
The enclosure should also include clear definitions of any used terms, such as train, division, loop, etc.
