'ATT-22.0 ATTACHMENT RESTORING FEED FLOW PAGE 2.of 3 STEP ACTION/EXPECTED RESPONSE RESPONSE NOT OBTAINED NOTE: o This attachment provides the desired feed flow rate when restoring feed flow to a S/G during FR-H.1.

o IF feedwater is restored via main feedwater or condensate the following may be used to indicate flow to the S/G:

o S/G feedwater flow meters (MCB) o S/G feedwater flow recorders (MCB) o S/G feedwater flow (PPCS Point ID F0466, F0467, F0476.,F0477) o S/G feedwater RTD temperature decrease (PPCS Point ID T2096, T2097) l Initiate Feed flow as follows:

a. Bleed and Feed initiated or a. IF feedwater flow to affected required S7G greater than 50 gpm OR affected SG level greater than 35 inches (100 inches adverse CNMT), THEN fill as desired to restore narrow range greater than 51. (25'/ adverse CNMT) and go to step 2 of this attachment.

IF NOT, THEN establish less than or equal to 100 gpm feed flow to affected S/G. WHEN S/G level greater than 35 inches (100 inches adverse CNMT). THEN.

as desired to restore narrow fill range greater than 5/o (25/.

adverse CNMT) and go to step 2 of this attachment.

b.'Check RCS temp stable or b. Fill ONE S/G at the highest decreasing possible flow rate and go to step 2 of this attachment.

c. Establish less than or equal to 100 gpm feed flow to affected S/G. WHEN S/G level greater than 35 inches (100 inches adverse CNMT), THEN fill as desired to restore narrow range greater than 5/. (25'/ adverse CNMT)
