Content:
oncludes 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 regulatory Position C-1 or C-2 in Regulatory Guide 1.29 or b. providing and meeting an alternative method to the regula- tory Position 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 components. 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 noncontaminated drainage. V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section. 9.3.3-6 Rev. 2 - July 1981 Except is those cases in which the applicant proposes an acceptable alternative method for complying with specified portions of the Commission's regulations, the method described herein will be used by the staff in its evaluation of conformance with Commission regulations.
