2.0 Indications 2.1 Abnormal steam generatc,: levels.

2.2 Abnormal auxiliary feedwater flows.

3.0 Probcble Cause 3.1 Loss of one or more auxiliary feedwater pumps.

3.2 Secondary coolant breaks on the secondary side of a steam h

generator.

Initials 5.0 long Term Operator Action NOTE: If a stean generator is dry, depressurize the primary systems to less than 16005 across the tube sheet and then cooldown and depressurize the primary aysten using the other operable steam generators.

If all three steam generators loosing level together, feed and bleed all three steam generators and increase levels very slowly. Reduce primary heat sources to a minimum by securing 2 reactor coolant pumps.

NOTE: When level in emergency condensate storage tank reaches 9 feet (37.3% as read on LI-CN-200 in control room) or when suction pressure to aux feed water pumps reaches 4 psig, commence filling the emergency condensate storage tank.

5.1 Verify valve checkoff sheet 2-OP-31.2A is completed.

5.2 Verify steam generator level indication is available.

5.3 Verify electrical power is available for MOV and/or HCV opera-tion. (Valves will have to be operated manually if power is h not available).

5.4 Unlock and open 2-FW-317 if it is desired to feed 2-RC-E-1B via MOV FW200B.

5.5 Unlock and open 2-FW-157 if it is desired to feed 2-RC-E-IC via HCV FW200C.

5.6 Isolate tne steam supply from affected steam generators to 2-FW-P-2 by closing 2-MS-13 from 2-RC-E-IA 1-MS-57 from 2-RC-E-1B, or 2-MS-95 from 1-RC-E-IC. .-

=v NOTE: Steam pressure will be higher in steam generators with lower levels. If Safety Injection has not occurred limit steam line differential pressure to less than 100# AP or safety injection will occur.

5.7 Open TV MS 211A or B to start 2-FW-P-2.

5.8 Regulate MOV FW 200D to control level in 2-RC-E-1A, MOV FW 2003

]

to control level in 2-RC-E-1B and HCV FW 200C to control level in 2-RC-E-1C. l 1
