              ,/                        August 14, 1987 Regulatory Guide 1.100 Proposed Revision 2 REGULATORY GUIDE DISTRIBUTION LIST FOR DIVISION 1 Your attention is directed to the change in the title of the attached proposed Revision 2 to Regulatory Guide 1.100, " Seismic Qualification of Electric and Mechanical Equipment for Nuclear Power Plants." Revision 1 of this guide covered electric equipment only; this proposed revision also covers mechani-cal equipment. Specifically, this proposed regulatory guide covers two cate-gories of equipment: (1) safety-related electric (Class IE) equipment and safety-related mechanical equipment and (2) equipment whose failure could prevent the satisfactory accomplishment of safety functions.
This draft regulatory guide endorses IEEE Std 344-1987, " Recommended Practice for Seismic Qualification of Class IE Equipment for Nuclear Power Generating Stations," with two exceptions.
Section 8.3 and Section 9 of IEEE Std 344-1987 provide guidance on the use of experience date for seismic qualification. The NRC staff believes that this approach is consistent with the proposed resolution of Unresolved Safety Issue (USI) A-46 (NUREG-1030, " Seismic Qualification of Equipment in 0perating Nuclear Power Plants," February 1987).
While comments and suggestiers are ancouraged in all areas, comments are specifically requested on the consistency of IEEE Std 344-1987 with the proposed resolution of USI A-46.
Written comments may be submitted to the Rules and Procedures Branch, Division of Rules and Records, Office of Administration and Resource Management, U.S.
Nuclear Regulatory Comission, Washington, DC 20555. Coments may also be delivered to Room 4000, Maryland National Bank Building, 7735 Old Georgetown Road, Bethesda, Maryland, from 8:15 a.m. to 5:00 p.m. Copies of coments received may be examined at the NRC Public Document Room, 1717 H Street NW.,
Washington, DC. Coments will be most helpful if received by October 30, 1987.
