What temperature does the Turbine Trip Steam Dump controller control at?

547* F

What temperature does the Load Rejection Controller control at?

552* F Rods take care of the other 5*

What is the input for the MFP DP Setpoint?

Total Steam Flow

What is the alternate power supply for the CRIDs?

600V thru the Isolimeter

If the CRID is on the alternate source of power (600 V), what is the status of the Inverter and Bus?

Inverter = INOP Bus = OPERABLE

If the CRID is on CRP-3 power source, what is the status of the CRID Bus?

INOP

What’s the MS pressures for U1 and U2 at 50% power?

U2 will be higher than U1 due to the higher temperature at which it operates

Steam dumps are in steam pressure mode and fail open. What is the minimum action to stop the cooldown involving the switches?

Take 1 switch to off

What’s the basis of the 46K FO Storage Tank Tech Spec?

1 EDG for 7 Days

VRS-1500, Vent Stack

What are the SC requirements during NC with and without CRDMs?

90*F with CRDMs 220*F without CRDMs

What would result in immediate suspension of core alts?

Loss of comms between the Control Room and Fuel Handling People

When evacuating the CR, how is CVCS cross-tie done and how is it monitored?

Opp Unit CCP suction to the RWST. Flow is tracked by the U1/2 cross-tie flow indicator

How does the AEO Trip the Rx Locally in FRS-1?

Rx Trip Breaker (1) Rx Trip Bypass Breaker (1) MG Set Output Breakers (2)

Has significant fuel damage occurred when CETs are at 1200*F?
