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 required b.'Check RCS temp stable or decreasing
- 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)
- a. IF feedwater flow to affected S7G greater than 50 gpm OR affected SG level greater than 35 inches (100 inches adverse CNMT), THEN fillas 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. fill as desired to restore narrow range greater than 5/o (25/.
adverse CNMT) and go to step 2
of this attachment.
- b. Fill ONE S/G at the highest possible flow rate and go to step 2 of this attachment.

NOT OBTAINED 2 Check RCS Loop Hot Legs BOTH HOT LEG TEMPERATURES DECREASING Return to step 1 of this attachment.
1 3 Verify affected S/G is not faulted or ruptured.
Return to step 1 of this-attachment and attempt to establish the intact S/G as heat sink.
Isolate feedwater and steam flow path to/from affected S/G.
jF neither S/G is intact, THEN establish a heat sink using the best available S/G.
