n SRP Section 3.5.1.1 and inside containment in SRP Section 3.5.1.2. f. the Containment Systems Branch (CSB)The Containment Systems and Severe Accident Branch (SCSB) determines that the blowdown lines penetrating the 21 primary containment are isolated on a containment isolation signal and evaluates containment isolation dependability (10 CFR 50.34(f)(2)(xiv) and22 10.4.8-3 DRAFT Rev. 3 - April 1996 NUREG-0737 Task II.E.4.2) as part of its primary review responsibility in SRP Section 6.2.4. g. The review of the quality assurance program is performed by the Quality Assurance BranchQuality Assurance and Maintenance Branch (HQMB) as part 23 of its primary review responsibility for SRP Sections 17.1, and 17.2, and 17.3.24 For those areas of review identified above as part of the primary review responsibility of other branches, the acceptance criteria necessary for the review and their methods of application are contained in the referenced SRP section of the corresponding primary branch. II. ACCEPTANCE CRITERIA CMEBEMCB accepts the design of the steam generator blowdown system if the relevant 25 requirements of General Design Criterion Criteria 1, 2, and 14 are met. The relevant 26 requirements are as follows: 1. General Design Criterion 1 (GDC 1), "Quality Standards and Records," as it relates to 27 system components being designed, fabricated, erected, and tested for quality standards. 2. General Design Criterion 2 (GDC 2), "Design Bases for Protection Against Natural Phenomena," as it relates to system components designed to seismic Category 1 28 requirements. 3. General Design Criterion 14 (GDC 14), "Reactor Coolant Pressure Boundary," as it 29 relates to secondary water chemistry control are complied with so that the primary 30 coolant boundary material integrity will be maintained. The steam generator tubes are part of the reactor coolant pressure boundary, and these tubes could be degraded by adverse chemistry conditions on the secondary site. The SGBS primary
