The temperature limit was exceeded due to a steam leak arour.d the packing of Valve FX057. The temperature was lowered to specification temperature by starting the RCIC fan coil unit. MWO M54442 was initiated to fix the leak.

This MWO has been worked and was completed on July 30, 1985.

Engineering reviewed the Environmental Qualification files for the equipment in the RCIC Room (Room 1A104) and verified that all equipment in this room has been qualified for temperatures of 105'F (or greater). Therefore, the operability of the RCIC Room equipment was not affected by the 104.5"F temperature.
