iNOTE 1: Steps 1 and 2 are izmediate operator actions.
STEP S 1.
Verify instrument failure by comparing suspect channel level indication and level recorder to other two channels.
STEP S*2. On pressurizer level control switch, select the position which has two operable channels.
STANDARD Compares LI-459 to LI-460 and LI-461 and recognizes that LI-459 has failed to 0%
level.
STANDARD Positions the PZR level control switch to the 460 - 461 position.
COMMENTS:
STEP

Select operable channel on the pressurizer level recorder.
STANDARD Verifies the pressurizer level recorder position switch channel 460.
iNOTE 4:
Critical if FCV-122 not full closed.
STEP
