- to be inoperable.- Appropriate fire watches were established at that time. On May 29, 1992, at-1400, these1LCOs exceeded seven days. Tentatively, the corrective

~

actions will include replacing the seals and securing the oil seepage.- The intial estimated time for completion of this work is March,1993r however, this work may be completed earlier af ter the preliminary engineering ia completed and the work scope ~ defined. Thia information will be included in a supplemental special Report. Until restoration of the seals, appropriate fire watches will remain in effect..These seal inoperabilities will also be reported in LER 1-92-016.
