ry guides, staff technical positions, and industry standards. The staff concludes that the design of the compressed air system is acceptable and conforms to the requirements of General Design Criteria 1, 2, and 5 with respect to quality standards, seismic design-, and sharing of systems and components. This conclusion is based on the following: 1. The applicant has met the requirements of General Design Criterion 1 with respect to quality standards by meeting ANSI MC 11.1-1976 (ISA S7.3) as related to minimum instrument air quality standards and meeting Regulatory Guide 1.68.3 as related to testing of instru- ment air systems. 2. The applicant has met the requirements of General Design Criterion 2 with respect to seismic design by meeting Regulatory Position C-1 or C-2 in Regulatory Guide 1.29. 3. The applicant has met the requirements of General Design Criterion 5 with respect to the capability of shared systems and components impor- tant to safety to perform required safety functions since a failure in the system will not impair the system's safety function for either unit. V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section. 9.3.1-6 Rev. 1 - July 1981 Except in those cases in which the applicant proposes an acceptable alterna- tive method for complying with specified portions of the Commission's regula- tions, the method described herein will be used by the staff in its evaluation of conformance with Commission regulations. Implementation schedules for conformance to parts of the method discussed herein are contained in the referenced regulatory guide. VI. REFERENCES 1.
