a. IF the controlling PRZR pressure o All 4 narrow range channels channel has failed, THEN place TRENDING TOGETHER 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 a. Go to Step 12.
b. Pressure - GREATER THAN 2000 PSIG b. IF pressure decreasing uncontrollably, THEN trip the reactor and go to E-O, REACTOR TRIP OR SAFETY INJECTION.
