ty of internally generated missiles 10 both inside and outside primary containment as part of its primary review responsibility for SRP Sections 3.5.1.1 and 3.5.1.2. c. The ASB SPLB also evaluates the capability of safety-related systems to 11 withstand the effects of missiles generated by natural phenomena or externally 9.3.4-3 DRAFT Rev. 3 - April 1996 generated missiles as part of its primary review responsibility to SRP Sections 3.5.1.4 and 3.5.2. d. The Auxiliary Systems Branch (ASB) SPLB , as part of its primary review 12 responsibility for SRP Section 3.6.1, evaluates the effect of high- and moderate-energy CVCS system piping failures outside containment to assure that other safety-related systems will not be made inoperable. e. The SPLB reviews the environmental qualification of mechanical and electrical safety-related equipment as part of its primary review responsibility for SRP Section 3.11.13 f. The SPLB evaluates the effect of cooling water system failures on reactor coolant pump seal integrity as part of its primary review responsibility for SRP Section 9.2.2.14 g. The SPLB reviews the CVCS system with respect to fire protection as part of its primary review responsibility for SRP Section 9.5.1.15 h. The liquid, solid, and gaseous waste treatment and process and effluent radiological monitoring aspects of the CVCS are reviewed in SRP Sections 11.2, 11.3, and 11.4, and 11.5, respectively, by the Effluent Treatment Systems Branch (ETSB) SPLB as part of its primary review responsibility for those sections. 16 2. The Reactor Systems Branch (SRXB) performs the following reviews: a. As part of its primary review responsibility for SRP Section 3.12 (proposed), the SRXB reviews the CVCS to verify that low-pressure portions of the CVCS that interface with the RCS are designed, to the extent practical, to withstand full RCS pressure. If designing the CVCS with an ultimate rupture strength capable of withstanding full RCS pressure is not possible, the reviewer
