h- nical specifications, and quality assurance are coordinated and performed by the Chemical Engineering Branch, Licensing Guidance Branch, and Quality Assurance Branch as part of their primary review responsibility for SRP Sections 9.5.1, 16.0, and 17.0, respectively. For those areas of review identified above as being the responsibility of other branches, the acceptance criteria and their methods of application are contained in the SRP sections identified as the primary review responsibility of those branches. 9.3.3-2 Rev. 2 - July 1981 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. Accep- tance 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 ASB uses the following to determine if portions of the EFDS are safety related: 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 regard. b. If the system can cause the inundation of safety-related areas due to drain backflow that may result from malfunction of active components, blockage or the probable maximum flood, it is considered safety related in this area. c. If the system is connected so that an inadvertent transfer of contami- nated fluids to noncontaminated drainage systems can occur, it is considered safety related in this area. d. If a failure or malfunction in a portion of the system could result in adverse effects on essential systems or components (i.e., necessary for safe shutdown, accident prevention, or accident mitigation) it is considered
