NOTE:

Actual PRZR pressure should be verified by more than 1 indicator.

1 Check PRZR Pressure:

o All 4 narrow range channels

'PPROXIMATELY EQUAL o All 4 narrow range channels TRENDING TOGETHER IF one pressure channel deviates significantly from the other 3, THEN perform the following:

a. IF the controlling PRZR pressure channel has failed, THEN place controller, 431K, in MANUAL and adjust output to restore PRZR pressure.

b. Refer to ER-INST.1, REACTOR PROTECTION BISTABLE DEFEAT AFTER INSTRUMENTATION LOOP FAILURE.

2 Check Reactor. Power STABLE IF the abnormal PRZR pressure is a result of a power transient, THEN evaluate conditions and go to the appropriate plant procedure.

3 Check PRZR Pressure:

a.

Pressure LESS THAN 2235 PSIG

b. Pressure GREATER THAN 2000 PSIG a.

Go to Step 12.

b. IF pressure decreasing uncontrollably, THEN trip the reactor and go to E-O, REACTOR TRIP OR SAFETY INJECTION.

b. IF PRZR pressure less than 2220 psig, THEN energize PRZR backup heaters.

IF PRZR backup heater breaker has tripped, THEN perform the following:

1) Place the breaker switch to OFF to reset breaker.

2) Place the breaker switch to ON to energize heaters.

3) Verify load increase on Bus 16.
