2-AP-22.1 Page 4 of 4 11-29-79 Initials 5.0 Lonz Term Ooerator Action NOTE: If a steam generator is dry, depressurize the primary systems to less than 1600!! across t'ue tube sheet and then cooldown and depressurize the primary system using the other operable steam generators.

If all three steam generators loosing level together, feed and bleed all three steam generators and increase level 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 inciation is available.

5.3 Verify Electric Power is available to 2-FW-P-3A and/or 2-FW-P-3B.

5.4 If required, close 2-FW-193 (2-FW-P-3B disch. to MOV Ndr.) .

5.5 If required, open 2-FW-194 (2-FW-P-3B disch. to HCV Edr.).

5.6 Unlock and open 2-FV-66 and 98 (HCV Edr. to "A" and "B" Stm.

Gen.).

5.7 Place the pump control mode selector switch (es) for the Auxiliary Steam Generator Feedwater Pump (s), 2-FW-P-3A and/or 3B to the START position.

5.8 Regulate HCV-FW-200A, B and C as necessary to maintain the

'

required steam generator levels.

5.9 Make-up to 2-CN-TK-1 as required.

NOTE: Return Auxiliary Feedwater System to normal by 2-AP-22.2 Completed By:
