performed by the Chemical Engineering Branch, Licensing Guidance BranchTechnical Specifications Branch (TSB) , and Quality Assurance Branch as part 31 of theirits primary review responsibility for SRP Sections 9.5.1, 16.0, and 17.0, respectively. 8. The review for quality assurance is coordinated and performed by the Quality Assurance and Maintenance Branch (HQMB) as part of its primary review responsibility for SRP Chapter 17.32 9. For new plant applicants, the equipment and floor drainage system may be included in the systematic assessment of shutdown risks as a feature that can minimize the risk of flooding during shutdown conditions. The Probabilistic Safety Assessment Branch (SPSB) coordinates and performs the shutdown risk assessment reviews as part of its primary review responsibility for SRP Section 19.1 (proposed).33 For those areas of review identified above as being the responsibility ofpart of the review under other SRP sectionsbranches, the acceptance criteria and their methods of application are contained in the referenced SRP sections identified as the primary review responsibility of those branches.34 DRAFT Rev. 3 - April 1996 9.3.3-4 II. ACCEPTANCE CRITERIA Acceptability of the design of the equipment and floor drainage system, as described in the applicant's safety analysis report (SAR) is based on the system meeting the following criteria: 1. General Design Criterion 2 as related to safety-related portions of the system being capable of withstanding the effects of earthquakes. Acceptance is based on meeting the guidance of Regulatory Guide 1.29, Position C-1, if any portion is deemed to be safety- related, and Position C-2, for nonsafety-related functions. The ASBSPLB uses the 35 following to determine if portions of the EFDS are safety-related : 36 a. If the system is capable of detecting leaks in safety systems that utilize the drainage system sumps, and is the only means for such leakage detection, it is considered safety-related in this
