A. PURPOSE This procedure provides actions to respond to a loss of all ac power.

B. ENTRY CONDITIONS This procedure was written for modes 1, 2, 3, and 4 assumina the RCS is hot and tressurized. Using this procedure when not in these modes requires a step by step evaluation to determine if the required action is still appliceble to current plant conditions.

1. On the loss of all ac power as indicated by the loss of both the normal and emergency ac busses.
2. This procedure is entered from E0P 35 E 0, REACTOR TRIP OR SAFETY INJZCTION, Step 3, on the indication that all ac emergency busses are deenergized.

1. CSF Status Trees should be monitored'for information only.

Other Functional Response Procedures should NOT be implemented unt!1 at least one ac Emergency bus is energized.

2. Adverse Containment is defined as contair. ment temperature

1. SG pressures should NOT be decreased to < 134 psig to prevent injection of accumulator nitrogen into the RCS.
2. SG N'.RROW range level should be maintained > 4% (14% for ADVERSE CONTAINNT.NT) in at Jeast one intact SG. If level cannot be maintained. SG depressurization should be stopped until level is restored in at least one SG.

NOTE

1. The SGs should be depressurized at maximum rate to minimize RCS invento ry loss.
2. PZR level may be lost and reactor vessel upper head voiding may occur due to depressurization of SGs. Depressurization should NOT be stopped to prevent these occurrences.
