hether the mathematical 5 modeling and computer codes have been previously reviewed and accepted by the staff. If a referenced method has not been previously reviewed, the reviewer initiates a generic evaluation of the new analytical model. The values of all the parameters used in the new analytical model, including the initial conditions of the core and system, are reviewed. The predicted results of the transient are reviewed to assure ensure that the consequences meet the acceptance criteria given 6 in subsection II of this Standard Review Plan (SRP) section. The analysis results are reviewed 7 to ascertain that pertinent system parameter valves values are within ranges expected for the 8 type and class of reactor under review. The Core Performance Branch (CPB) upon request from RSB,SRXB will verify that the core 9 physics data used by the applicant, or by the staff in independent analyses, is the are appropriate data to be used as part of its primary review responsibility for SRP Sections 4.2 through 4.4. The CPBSRXB will also verify, if requested, that acceptance criteria criterion 1 of SRP 10 11 12 Section 4.4 is satisfied throughout the transient. Review Interfaces13 The RSBSRXB will coordinate other branch evaluations that interface with the overall review 14 of this SRP section, as follows: 1. The Instrumentation and Controls Systems Branch (ICSB)(HICB) reviews the 15 16 instrumentation and controls aspects of the sequence described to confirm that the reactor and plant protection and safeguards controls and instrumentation systems will function as assumed in the safety analysis as part of its primary review responsibility for SRP Sections 7.2 through 7.5. Upon request, ICSBHICB will verify the sequence described 17 by the applicant for the safety analysis with regard to automatic actuation, remote sensing, indication, control, interlocks with auxiliary or shared systems, potential bypass modes, and the possibility of manual control by the operator. 2. The
