l L -* 2-AP-22.3 Page 4 of 4 11-29-79 Initials 5.0 Long Term Operato- Action i NOTE: If a steam generator is dry, depressurize the primary systems to less than 16000 across the tube sheet and ) then cooldown and depressurize the primary system using i the other operable steam generators. l If all three steam generators loosing level together, feed and bleed all three steam generators and' increase l 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 check off sheet 2-OP-31.2A is completed. 5.2 Verify steam generator level indication is available. 5.3 Verify electrical power is available to 2-FW-P-3A and/or 3B. 5.4 If required, close 2-FW-174 (2-FW-P-3A Disch. to HCV Edr.). 5.5 If required, open 2-FW-173 (2-FW-P-3A Disch. to MOV Edr.) . 5.6 Unlock and open 2-FW-64 and 128 (MOV Edr. to "A" and "C" Stm. Gen.). 5.7 Place the Pump Control Made Selector Switch (es) for the Aux-iliary Steam Generator Feedwater Pump (s) 2-FW-P-3A and/or 3B to the " START" position. 5.8 Regulate MOV-FW-200A, B and C as necessary to maintain the required steam generator levels. 5.9 Make-up to 2-CK-TK-1 as required. NOTE: Return auxiliary feed water system to normal by 2-AP-22.4 before going above mode 4. Completed By: Date: l}}
