EOP Facts Flashcards
During RPV floodup, what is the elevation of top of active fuel?
83.9 feet (35 psid)
During RPV floodup, what is the maximum primary containment water level?
103.5 ft (43.5 psid)
What indications are available in the control for primary containment flooding?
On Control Room panels 2H11-P657 and P654, 2T48-R622A and B, Wide Range Torus Wtr Lvl, will indicate torus water levels below 25 feet (300 inches).
Actions to transfer HPCI from injection to pressure control?
Reset the HPCI initiation signal
IF the HPCI initiation cannot be reset,
THEN do NOT perform this section (EOP-107)
With the HPCI Flow Controller in Auto, closing 2E41-F008 will increase the cooldown rate.
Actions to transfer RCIC from injection to pressure control?
IF RCIC MANUAL INITIATION PUSH BUTTON IS DEPRESSED, INJECTION TO VESSEL WILL INITIATE. IF INJECTION IS INITIATED, IT CAN BE STOPPED BY DEPRESSING THE RCIC INITIATION SIGNAL RESET PUSH BUTTON AND THEN CLOSING 2E51-F013, PUMP DISCHARGE VLV.
Maximum dp for MSIVs?
The MSIVs are designed to open against a dP of up to 200 PSID.
Steps for RWCU blowdown for alternate pressure control?
THIS SECTION IS NOT TO BE PERFORMED IF BORON HAS BEEN, OR
IS BEING INJECTED TO THE RPV.
OPEN
2G31-F034, Disch To Main Cndsr Vlv, _____
OR
2G31-F035, Drain to Waste Coll Vlv, At panel 2H11-P602. _____
DO NOT OPEN BOTH OF THESE VALVES AT THE SAME TIME.
Maintain the Non-Regenerative Heat Exchanger effluent temperature at <120°F,
Maximum SJAE steam supply pressure?
do not exceed 360 psig
HPCI for alternate RPV depressurization
Adjust 2E41-R612, HPCI Flow Control,
to obtain 4250 GPM AND
throttle 2E41-F008 CLOSED
UNTIL the Turbine Control Valve is Full OPEN,
DO NOT exceed 1500 psig discharge pressure.
RCIC for alternate RPV depressurization
3.4.15 Adjust 2E51-R612, Turbine Controller,
to obtain 400 GPM AND ______
3.4.15.1 Throttle, 2E51-F022, CLOSED
UNTIL Turbine Governor Valve is FULL OPEN,
DO NOT exceed 1500 psig discharge pressure.
RFPT for alternate RPV depressurization
- This subsection provides an alternate method of RPV Depressurization by operating the Reactor Feed Pump Turbines. This subsection is to be performed ONLY WHEN the Condensate/Feedwater System is NOT required for RPV water level control AND the Main Condenser can be placed in operation with at least 7.0 in Hg. vacuum.
- The RFPTs will trip on low vacuum of 22.3 in Hg vacuum if speed goes above 3500 RPM
What to do for alternate depress when vacuum is less than 10 in. Hg?
IF vacuum of at least 10 in. Hg vacuum CANNOT be drawn on Main Condenser,
(Monitor → LP Hoods , 2N32-K4001A OR 2N32-K4001B) OR SPDS,
THEN confirm OPEN/OPEN Main Condenser Vacuum Breaker Valves
AND
START all available Turbine Building HVAC per 34SO-U41-001-2, Turbine Building Ventilation System.
Alternate depress with RWCU
THROTTLE 2G31-F044, Demin Bypass Vlv,
to establish a system flow rate of 250-260 GPM.
During alternate boron injection, what is runout condition with CRD?
THE CRD PUMPS WILL EXPERIENCE A RUNOUT CONDITION AT ≈190 GPM.
THIS CORRESPONDS TO A DISCHARGE PRESSURE OF ≈ 1180 PSIG.
THE NET POSITIVE SUCTION HEAD REQUIRED FOR THIS FLOW CONDITION IS 18.0 INCHES HG VACUUM.
HPCI Injection flow prior to disabling min flow?
HPCI system must be injecting to vessel with more than 960 gpm (set point for min flow valve operation) flow rate to allow proper cooling of HPCI pump prior to disabling the Min Flow Valve.
