tdown, accident prevention or accident mitigation) it is considered safety-related in this area. The basis for acceptance in the staff review has been conformance of the applicant's designs and design criteria for the essentialsafety-related portions of the equipment and 60 floor drainage system and necessary auxiliary supporting systems to the Commission's regulations as set forth in the general design criteria, and to applicable regulatory guides, staff technical positions, and industry standards. 9.3.3-9 DRAFT Rev. 3 - April 1996 The staff concludes that the design of the equipment and floor drainage system is acceptable and conforms to the requirements of General Design Criteria 2, 4, and 60 with respect to seismic design, environmental conditions, and control release of radioactive materials. This conclusion is based on the following: 1. The applicant has met the requirements of General Design Criterion 2 with respect to seismic design by a. meeting rRegulatory Position C-1 or C-2 in Regulatory Guide 1.29 or 61 b. providing and meeting an alternative method to the rRegulatory Position 62 C-1 or C-2 in Regulatory Guide 1.29 that the staff has reviewed and found to be acceptable. 2. The applicant has met the requirements of General Design Criterion 4 with respect to environmental conditions by preventing flooding which could result in adverse effects on essential systems or componentsSSCs important to safety . 63 3. The applicant has met the requirements of General Design Criterion 60 with respect to controlling release of radioactive materials by preventing the inadvertent transfer of contaminated fluids to portions of the systems for non-contaminated drainage. For design certification reviews, the findings will also summarize, to the extent that the review is not discussed in other safety evaluation report (SER) sections, the staff's evaluation of inspections, tests, analyses, and acceptance criteria (ITAAC), including design acceptance criteria (DAC), site
