Associated Block Valves - ANY BLEED PATH OPEN o IF RWST level greater than 28%.

THEN go to E-1, LOSS OF REACTOR OR SECONDARY COOLANT.

-OR-o IF RWST level less than 28%,

THEN go to ES-1.3, TRANSFER TO COLD LEG RECIRCULATION.

36 Isolate PRZR Bleed Paths:

a. PRZR PORVs - BOTH OPEN a. Perform the following:

1) Stop all but one charging pump.

2) Control charging flow as necessary to maintain RCS pressure and PRZR level.

3) Establish excess letdown as follows:

a) Place AOV-312 to NORMAL.

b) Ensure CCW pump running.

c) Manually open CCW from excess letdown Hx open (AOV-745).

d) Ensure excess letdown flow control valve. HCV-123 is closed, demand at 0.

e) Reset both trains of XY relays for MOV-313.

f) Open MOV-313.

g) Open excess letdown isolation valve AOV-310.

h) Slowly open HCV-123.

b. Check RCS pressure: b. Go to appropriate plant procedure:

1) Pressure - GREATER THAN 250 psig [465 psig adverse o IF RWST level greater than CNMT] 28%. THEN go to E-1, LOSS OF REACTOR OR SECONDARY COOLANT.
