| 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.
