Which of the following are sources of input to the boron recovery tanks?
CVCS L/D
spent fuel cooling
primary drains transfer tank (PDTT)
containment drains transfer tank (CDTT)
pressure relief tank (PRT)
What would cause the boron recovery evaporator distillate to be diverted from the boron test tanks to the boron recovery tanks?
distillate conductivity high-high
Which of the following will trip a boron evaporator feed pump?
low suction pressure
What is the purpose of the boron recovery cesium ion exchanger?
remove fission products from coolant entering the boron recovery tanks
What is the purpose of the boron evaporator rebiller system?
the reboiler system heats the evaporator feed water/evaporator bottoms solution to facilitate flashing some of the water within the evaporator shell
The boron recovery system is utilized to:
recover and reconstitute borated waste water for use in the boric acid tanks
Borated reactor coolant from the CVCS is processed in the boron recovery system by the ______ to remove dissolved radioactive fission products.
cesium removal ion exchangers
The _____ would be used to pump water from the boron recovery tanks to the high level waste drain tanks.
boron evaporator feed pumps
The contents of the boron distillate tank are pumped to the _____ for disposition to the liquid rad waste system.
boron test tanks
The boron evaporator reboiler system is used to:
heat the boron evaporator liquid to boiling temperatures
When processing the boron recovery tank contents, the boron evaporator level is maintained by the:
boron evaporator level controller, 3BRS-LIC37
Which one of the following boron recovery system components does NOT utilize CCP?
boron evaporator bottoms pump seal water supply
Boron evaporator reflux flow is produced by the discharge of the ______ , and used to _______.
boron evaporator distillate pump
wash borated droplets collected on the boron evaporator vapor trays
The boiling rate in the boron evaporator can be increased by:
INCREASING the CCP flow to the boron evaporator condenser
PT-28, boron evaporator condenser pressure is used to control the boron evaporator condenser pressure by:
A failure HIGH of 3BRS-PT28, boron evaporator condenser pressure transmitter, will result in:
OPENING of 3BRS-PV104, CCP flow control valve to the boron evaporator condenser
Which is NOT a requirement for operation of the boron evaporator bottoms pump in the “After Start” position?
boron evaporator bottom coolant temperature is less than 130F
All boric acid piping containing 6 weight percent boric acid must:
have its associated heat tracing energized to prevent boron precipitation
The boron evaporator bottoms coolant preheater, 3BRS-E6, is used to:
heat the CCP coolant to > 150F to assure the bottoms are not excessively cooled
