s p MIDLAND PLANT UNITS 1 AND 2 REGULATORY GUIDE REVIEW 1. Regulatory Guide 1.63 Electric Penetration Assemblies in Containment Structures for Water-Cooled Nuclear Power Plants" - (October 1973) This guide describes an acceptable method of complying with General Design Criterion 50 and Appendix B to 10 CFR Part 50 with respect to the mechanical, electrical, and test reouirements for the design, construction and installation of electric penetration assemblies in containment structures for water-cooled nuclear power plants. The staff has reviewed the applicant's alternative to Position C.1 of this guide and has concluded that it is not acceptable. The applicant's alternate design criteria are not equivalent to the requirements of Regulatory Position C.1 including IEEE 279-1971. It is the staff's position that Position C.1 of Regulatory Guide 1.63 or an acceptable alternate with justification, be incorporated into the Midland Units 1 and 2 design. The applicant is required to provide this informatloa for review. l 1 1

Regulatory ide 1.73 " Qualification Tests of Electric Valve Operators Installed Inside the Containment of Nuclear Power Plants" - (January 1974) This guide describes an acceptable method of complying with Appendix 8 to 10 CFR Part 50 with regard to qualification testing of Class I electric valve operators for service within the contain-ment to assure that the valve operator design will meet its perform-ance requirements. The staff has reviewed the applicant's response provided in the enclosure to the letter of February 3,1976, defining the diff-erences between the Draft 13 and the April 10, 1973, versions of IEEE Std 382. This was the only exception taken by the applicant to the guidelines of Regulatory Guide 1.73. The staff has reviewed these differences and has concluded that the Draft 13 version of IEEE Std 382 does not provide less conservative testing requirements than the April 10, 1973 version. Accordingly, the staff concludes that use of the Draft 13 version of IEEE Std 382 represents an acceptable alternate for implementing the recommendations of this guide. l l n-n

S w p 3. Regulatory Guide 1.75 " Physical Independence of Electric Systems" - (Revision 1 January 1975) This guide describes an acceptable method of complying with IEEE Standard 279-1971 and General Design Criteria 3,17 and 21 with respect to physical independence of the circuits and electric equipmrat comprising or associated with the Class IE power system, the protection system, systems actuated or controlled by the protection system, and auxiliary or supporting systess that must be operable for the protection system and the systems it actuates to perform their safety related functions. The staff has reviewed the applicant's response concerning the exceptions to Regulatory Guide 1.75 (enclosure to letter of February 3,1976) and has concluded it is unacceptable. The staff requires that the applicant provide justification for each exception taken to Regulatory Guide 1.75. This information should be presented in detail to demonstrate how the desion satisfies the requirements of General Design Criteria 3,17, and 21 as well as IEEE Std 279-1971, all of which the recommendations of Regulatory Guide 1.75 satisfy. The applicant is required to provide this infonnation for review. - 1 t - ~< +: y pw .,-_..m.
