on of the new analytical model. The predicted results of moderator dilution events are reviewed by RSBSRXB to assure that the 7 consequences meet the acceptance criteria given in subsection II of this SRP section. Further, the results of the transients are reviewed to ascertain that the values of pertinent system parameters are within ranges expected for the type and class of reactor under review. Review Interfaces8 SRXB also performs the following reviews under the SRP sections indicated: 1. The Core Performance Branch (CPB) rReviews the values of the reactivity parameters used in the analyses as part of its primary review responsibility for SRP Section 4.3 and also performs, upon request, additional analyses related to these accidents for selected 9 10 reactor types as part of its primary review responsibility for SRP Sections 4.2 and 4.4. 2. The RSBSRXB review of SRP Section 6.3 covers the systems for emergency injection 11 of borated cooling water. In addition, the RSBSRXB will coordinate the other branches' evaluations that interface with 12 the overall review of the system as follows: 1. The Instrumentation and& Controls Systems Branch (ICSBHICB) reviews the 13 instrumentation and control aspects of the sequence described in the SAR to confirm that reactor and plant protection, and safeguardsengineered safety features (ESF) controls, interlocks, and other instrumentation and control systems important to safety will function as assumed in the safety analysis as part of its primary review responsibility for SRP Sections 7.2 through 7.57.14 2. The Materials and Chemical Engineering Branch (CMEBEMCB) reviews the functional 15 and operational characteristics and potential failure modes of the CVCS as part of its primary review responsibility for SRP Section 9.3.4. The RSBSRXB reviewer makes 16 use of this review to evaluate initiating causes and the expected sequence of events. For those areas of review identified above as being reviewed as part of the primary
