REV: 3 FR-S.2 RESPONSE TO LOSS OF CORE SHUTDOWN PAGE 2 of 5 A. PURPOSE This procedure provides actions to restore the core to an adequate shutdown condition.
B. ENTRY CONDITIONS/SYMPTOMS
- 1. ENTRY CONDITIONS This procedure is entered from:
- a. F-0.1, SUBCRITICALITY Critical Safety Function Status Tree, on either YELLOW condition.
EOP:
REV: 3 FR-ST 2 RESPONSE TO LOSS OF CORE SHUTDOWN PAGE 3 of 5 STEP ACTION/EXPECTED RESPONSE RESPONSE NOT OBTAINED NOTE: o Adverse CNMT values should be used whenever CNMT pressure is greater than 4 psig or CNMT radiation is greater than 10+ 5 R/hr.
o Adverse CNMT conditions or loss of forced air cooling may result in failure of NIS detectors.
1 Check Intermediate Range Flux:
- a. Flux - EITHER CHANNEL LESS THAN a. Continue with Ste~ 2. WHEN flux 10-10 AMPS is LESS THAN 10 amps on any operable channel, THEN do Steps lb, c and d.
- b. Check the following: b. Continue with step 2. WHEN either condition met, THEN do o Both intermediate range Steps lc and d.
channels - LESS THAN 10 AMPS
-OR-o Greater than 20 minutes since reactor trip
- c. Verify source range detectors cd Manually energize source range ENERGIZED detectors by depressing P-6 permissive defeat pushbuttons (2 of 2).
IF source ranges can NOT be restored, THEN refer to ER-NIS.1, SR MALFUNCTION, and go to Step 2.
d, Transfer Rk-45 recorder to one sour'ce'ange and one intermediate range channel

REV' FR-Ss2 RESPONSE TO LOSS OF CORE SHUTDOWN PAGE 4 of 5 STEP ACTION/EXPECTED RESPONSE RESPONSE NOT OBTAINED NOTE: If offsite power is lost coincident with SI, then MCC C and MCC D lockout relays must be reset to restore BA and RMW pumps.
2 Initiate Immediate Boration Of RCS:
- a. Check SI status:
o All SI annunciators- 1) Complete the immediate EXTINGUISHED actions of E-O, REACTOR TRIP OR SAFETY INJECTION, while o All SI pumps - OFF IN AUTO continuing with this procedure
- 2) IF SI flow indicated, THEN go to Step 3. IF NOT, THEN go to Step 2b.
- b. Verify at least one charging b. Perform the following:
pump - RUNNING
- 1) Reset SI if necessary.
- 2) Start one charging pump.
- c. Align boration path: c. Initiate normal boration at maximum rate using the boric
- 1) Start tue BA transfer pumps acid flow control valve, FCV-110A. IF flow can NOT be
- 2) Open MOV-350 I established, THEN refer to ER-CVCS.l, REACTOR MAKEUP
- 3) Verify BA flow CONTROL MALFUNCTION.
- d. Verify charging flow path: !
- d. Manually align valves and verify flow.

o Source range channels startup rate - ZERO OR NEGATIVE 4 Verify Adequate Shutdown Margin
- a. Direct HP to sample RCS for boron concentration I
- b. Verify boron concentration- b. Continue boration until adequate GREATER THAN REQUIREMENTS OF shutdown margin verified.
