on of new ones must be reviewed to determine that they are justified on theoretical or empirical grounds. A secondary review is performed by ICSB, HFEB, and PTRB. ICSBSRXB will review the 8 functional performance and requirements for the Inadequate Core Cooling (ICC) monitoring system hardware. Emergency procedure guidelines and the information display will be reviewed by PTRB and HFEB, respectively. The results of these reviews will be used by CPB to complete the overall evaluation of the thermal-hydraulic review and will be incorporated into the Safety Evaluation Report (SER).9 The review of power distribution assumption made for the core thermal and hydraulic analysis is coordinated with the review for core physics calculations, as described in the Standard Review Plan (SRP) Section 4.3, for consistency. The reviewer verifies that core monitoring techniques which rely on in-core or ex-core neutron sensor inputs are reviewed.10 4.4-3 DRAFT Rev. 2 - April 1996 Review Interfaces:11 SRXB also performs the following review under the SRP section indicated:12 The review of power distribution assumptions made for the core thermal and hydraulic analysis 13 is coordinated with the review for core physics calculations, as described in the Standard Review Plan (SRP) Section 4.3, for consistency. The reviewer verifies that core monitoring techniques which rely on in-core or ex-core neutron sensor inputs are reviewed.14 SRXB will coordinate other branches' evaluations that interface with the overall review of the system as follows:15 1. The Mechanical Engineering Branch (EMEB) reviews the adequacy of components and structures under accident loads, and the preoperational vibration test program as part of its responsibility for SRP Section 3.9.2.16 2. The Instrumentation and Controls Branch (HICB) will review the core protection and reactor protection hardware for compliance with requirements applicable to reactor trip systems as part of its primary review responsibility for SRP
