Content:
The RSB reviewer concentrates on the need for the reactor protection system, the engineered safety systems, and operator action to secure and main- tain the reactor in a safe condition. The analytical methods are reviewed by RSB to ascertain whether mathematical modeling and computer codes have been previously reviewed and accepted by the'staff. If a referenced analytical method has not been previously reviewed, the RSB reviewer initiates a generic evaluation of the new analytical model. In addition, the values of all the parameters used in the new analytical model, including the initial conditions of the core and system, are reviewed. The RSB will coordinate other branch evaluations that interface with the overall review of the transient analyses as follows: The Instrumentation and Control Systems Branch (ICSB) reviews the instrumentation and controls aspects of the sequence described in the SAR to evaluate whether the reactor and plant protection and safeguards controls and instrumentation systems wll function as .assumed in the safety analysis with regard to automatic actuation, remote sensing, indication, control, and interlocks with auxiliary or shared systems as part of its primary review responsibility for SRP Sections 7.2. through 7.5. The Core Performance Branch (CPB) upon request from RSB, reviews the values of the parameters used in the analytical models which relate to the reactor core for conformance to plant design and specified operating condi- tions; determines the acceptance criteria for fuel cladding damage limits; and reviews the core physics, fuel design, and core thermal-hydraulics data used in the SAR analysis as part of its primary review responsibility for SRP Sections 4.2 through.4.4. The Accident Evaluation Branch (AEB) using fuel damage results provided by RSB evaluates the radiological consequences associated with the fuel failure. The review of the Technical Specifications is coordinated and performed by the Licensing Guidance Branch
