A. EUREQSI ,

This procedure provides actions required to restore RH System cooling in the event RH System cooling is lost during Modes 4, 5, l or 6.

B. SIMEIQMS._.0lLINIRL101mlIl0115

1. The follouing annunciators may cause entry into this procedure:

o RH PUMP TRIP - alarm ;

o RH PUMP 1A(B) DSCH PRESS HIGH - alarm o RH PUMP 1A(B) DSCH PRESS LOW - alarm o RH PUMP 1A(B) CC FLOW LOW - alarm ,

o RH HX CC WTR FLOW HIGH LOW - alarm o RCS SYSTEM COLD PRESS HIGH - alarm o RCS PRESS HIGH AT LOW TEMP - alarm o CC PUMP TRIP - alarm o CC SURGE TANK LEVEL HIGH LOW - alarm >

o CC PUMP DSCH PRESS LOW - alarm b(~N o REACTOR VESSEL LEVEL LOW - alarm t

2. The following symptoms may cause entry into this procedure:

o Oscillating Rd pump amps.

o Fluctuating RH Pump dsch pressure.

.o Excessive RH Pump noise or vibration, o Fluctuating Letdown Flow when on RH Letdown.

o Decreasing Reactor vessel level ,

o Increasing RCS temperature.

o Increasing RH system temperature.

3. This procedure may be entered from:

o 1BwFR-C.3, RESPONSE TO SATURATED CORE COOLING, Step 1.

o Inability to reduce RCS temperature while shutdown.

o Loss of RH System while operating in Modes 4, 5, or 6.
