P Dr. J. Nelson Grace SPR 85-006 June 18, 1985 EVENT DESCRIPTION During the course of a re-evaluation of South Carolina Electric and Gas Company's (SCE&G) compliance with 10CFR50 Appendix R,

" Fire Protection Program for Nuclear Power Facilities Operating Prior to January 1, 1979," it was identified that an "A" d ivis io n vital power system tray was not separated from "B" d iv is ion trays containing cables for redundant func t ion s . Appendix R requires one redundant train to be wrapped in a one hour fire barrier where separation is less than twenty feet with fire detection and automatic fire suppression in the area. A fire which cou ld damage these "A" and "B" d ivis ion trays wou ld compromise or p r e c lu d e the use of redundant systems and equipment necessary for operation and safe shutdown.

CORRECTIVE ACTION A one-hour roving fire watch was e s t ab lis hed for the area. The feas ibility of wrapping the "A" division tray inv o lv e d is being eva lu a t ed . Modifications to meet Appendix R requirements will be completed by March 31, 1986.
