What is the purpose of verifying circulating water flow when making liquid waste discharges?
to provide proper dilution flow in the circulating water discharge tunnel during LWS discharge
Unit at 85% power
Outside air 75F
“A” WTT discharge is in progress
Rad monitor *RE70 is inoperable
At what tank level will the “A” WTT discharge be terminated, and what is the basis for this level?
4%, whenever outside air is greater than 40 degrees, a WTT may be discharge to 4%
During preparations for discharge of the “B” WTT, chemistry samples reveal unacceptable levels of hydrazine present in the tank. As the rad waste operator, what action should you take?
contact the rad waste coordinator for advice
The purpose of the waste test tank is to _____.
collect the contents of the HLWDT (after passing through waste demin filter 3 and waste demin 2), AND the distillate from the waste evaporator
The purpose of the low level waste drain tank is to ____.
accept and store low level radioactive liquid waste from the reactor plant aerated drains systems and high level waste drain tank
The purpose of the high level waste drain tanks are to collect and store radioactive liquid waste directly from all the following sources except:
charging and volume control system
The purpose of the waste test tank heaters is to ____.
prevent contents of waste test tanks from freezing
The purpose of the radioactive liquid waste system is to:
collect, process, monitor, and recycle or dispose of radioactive liquid wastes
When transferring liquid from a high level waste drain tank to a waste test tank, the liquid is processed by the ____.
waste demineralizer filter 3 and waste demineralizer 2
Which pump is used to provide flow when drawing a sample from a waste test tank?
waste test tank heater recirc pump
The _____ would be used to discharge fluid from the waste test tank to the circulating water system.
waste test tank pump 3LWS-P6A/B
When discharging a low level waste drain tank to the circulating water system, the liquid is ____.
sent through an empty filter housing, and is discharged unfiltered
What pump is used to transfer liquid waste from a high level waste drain tank to a waste test tank?
a waste evaporator feed pump
When discharging the contents of a waste test tank to the circ water system, the fluid is _____.
bypassed around the waste demineralizer 1 and waste demineralizer filter 1
When transferring the contents of a high level waste drain tank to a waste test tank:
3LWS-AOV103, WTT/HLWDT divert valve, is first placed in the “High waste drains tanks” position for at least 15 minutes
When transferring contents of a high level waste drain tank to a waste test tank _____.
the fluid is processed first by waste demin filter 3 then waste demin 2
When transferring fluid from a waste test tank to a high level waste drain tank, the fluid ___.
bypasses the waste demin 1 and waste demin filter 1
Which of the following signals will cause 3LWS-HV77, “Waste discharge tunnel stop valve”, to close?
high radiation (RE70) OR rad monitor RE70 failure
