A. BIRE01E This procedure provides actions required to restore RH System cooling in the event RH System cooling is lost during Modes 4 or 5 or 6.
! B. SYMPTOMS OAJNIRY_CONDITIQHS
- 1. The following annunciators may cause entry into this procedure:
l o RH PUMP TRIP - alarm o RH PUMP 1A(B) DSCH PRESS HIGH - elarm 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 p- o CC SURGE TANK LEVEL HIGH LOW - alarm i o CC PUMP DSCH PRESS LOW - alarm
- 2. Tne following symptoms may cause entry into this procedure: l o Oscillating RH pump amps.
o Fluctuating RH Pump dsch pressure.
! o Excessive N3 Pump noise or-vibration.
Fluctuating Letdown Flow when on RH Letdown.
o o Decreasing Reactor vessel level o Increasing RCS temperature. l 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.
