nditions is performed 25 by the Containment Systems Branch (CSB)Containment Systems and Severe Accident Branch (SCSB) as part of its primary review responsibility for SRP Section 6.2.1. 26 SEBThe ECGB accepts the loads thus generated, as approved by the CSBSCSB, to be 27 28 included in the load combinations in this SRP section. 4. The review for quality assurance is coordinated and performed by the Quality Assurance 29 BranchQuality Assurance and Maintenance Branch (HQMB) as part of its primary 30 review responsibility for SRP Section 17.0Chapter 17.31 5. The ECGB coordinates with the Materials and Chemical Engineering Branch (EMCB) regarding exclusion of postulated pipe ruptures from the design basis, generally referred to as the "leak before break (LBB)." The EMCB performs a review of those applications that propose to eliminate consideration of design loads associated with the dynamic effects of pipe rupture, as part of its primary review responsibility for SRP Section 3.6.3 (to be developed).32 3.8.4-7 DRAFT Rev. 2 - April 1996 For those areas of review identified above as being reviewed 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 sections of the corresponding primary branch.33 II. ACCEPTANCE CRITERIA SEBThe ECGB acceptance criteria for the design of structures other than containment are 34 based on meeting the relevant requirements of the following regulations: A. Part 50 of 10 CFR, § 50.55a and General Design Criterion 1 (GDC 1) as they relate to 35 safety-related structures being designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety function to be performed. B. General Design Criterion 2 (GDC 2) as it relates to the design of the safety-related 36 structures being capable to withstand the most severe natural phenomena such as wind, tornadoes, floods, and earthquakes
