nal testing and the instrumentation and control features that verify that the system is available to operate in the correct mode. Review Interfaces: 6 ASBSRXB also performs the following reviews under the SRP sections indicated: 7 1. The Core Performance Branch (CPB)Determines the adequacy of the specified boron 8 neutron absorber quantities and concentrations required in the primary coolant to assure that the plant can be brought from rated power to cold shutdown at any time in core life with the control rods withdrawn in the rated power pattern as part of its primary review responsibility for SRP Section 4.3. 2. Review of flood protection is performed under SRP Section 3.4.1; 3. Review of the protection against internally generated missiles is performed under SRP Sections 3.5.1.1 and 3.5.1.2; 4. Review of the structures, systems and components to be protected against externally generated missiles is performed under SRP Section 3.5.2; 5. Review of high- and moderate-energy pipe breaks is performed under SRP Section 3.6.1; and9 2. Review to verifyVerifies that redundant reactivity control systems are not vulnerable to common mode failures is performed underas part of its primary review responsibility for SRP Section 4.6. 10 3. Reviews the design of the SLCS for new designs to verify, to the extent practical, that low-pressure portions of the SLCS that interface with the RCS will withstand full RCS pressure, as part of its primary review responsibility for SRP Section 3.12 (proposed). If designing the SLCS with an ultimate rupture strength capable of withstanding full RCS pressure is not possible, the SRXB verifies that appropriate compensating measures have been taken in accordance with the review provided in SRP Section 3.12 (proposed).11 In addition, the ASBSRXB will coordinate other branches' evaluations that interface with the 12 overall review of the system as follows: 1.
