n the analytical models, and the predicted consequences of the transients. The sequence of events described in..the SAR analysis is reviewed by RSB in consultation with the Instrumentation and Control Systems Branch (ICSB). The RSB reviewer concentrates on the assumptions used 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 that all mathematical models and computer codes have been previously reviewed and accepted by the staff, If a referenced analytical method or code has not been previous1l reviewed, the RSB reviewer requests initiation of a generic evaluation of the new analytical model or code by RSB'or the Core Performance Branch (CPB), as appropriate. The'predicted results of the transient-analyses are then reviewed to assure that the consequences meet the acceptance criteria given in subsection !I, .15.2.1-2 Rev. 1 - July 1981 below. Further, the results of the analyses are reviewed to ascertain that the predicted values of pertinent system parameters are within expected ranges for the type and class of reactor under review. The RSB will coordinate other branches' evaluations that interface with the overall review of the transient analysis as follows: The ICSB review of SRP Sections 7.2 and 7.3 is consulted on the instrumentation and controls aspects of the sequences described in the SAR to evaluate whether the reactor and plant protection and safeguards controls and instrumentation systems will function as assumed in the safety analysis with regard to automatic actuation, remote sensing, indication, control, and interlocks with auxiliary or shared systems. ICSB also reviews potential bypass modes, and the possibility of manual control by the operator as part of its primary review responsibility for SRP Sections 7.2 through 7.5. The Core Performance Branch (CPB) reviews the values of all the parameters used in
