What is Manipulator Repair Shop/Regulated Machine Shop
While glycolic acid is being added to the SRAT, this valve is interlocked closed to prevent an unwanted chemical reaction
What is Nitric Acid Addition Valve
The MWWT rests on this tank
What is SMECT
this pump has in-line pH monitors and is designed to run continuously.
What is SMECT Sample Pump
If the MWWT Water Removal Valve is open, condensate will be directed to this vessel.
What is SRAT
To avoid interlock shutdown, the analytical lab supply fan and the fan supplying this area must be started within 30 seconds.
What is Level 1 North/Level 3 West
If the LPW priming valve for the SME Transfer Pump didn’t close in time, you would receive this alarm at the console.
What is Priming Overtime
This tank provides emergency backup for melter cooling water heat exchangers
What is Clean Condensate Tank
The SRAT heating coil steam supply valve can be in either CLOSE or this position, where it can control for either flow or temperature.
What is MODULATE
The temperature of the MST/Sludge Solid mixture in the PRFT is maintained within this band.
What is 20-30 degrees Celsius.
These are the two main functions of an ASU cooling coil.
What is cooling and dehumidification
HCV1899 on the Process Chilled Water system will interlock open if a pump is running and this other condition is met in order to maintain flow.
What is both chiller inlet valves closed
The transfer of RSS to SWPF from tank 49 at the tank farm occurs via a jumper placed in the cell where this vessel is housed.
What is the Recycle Waste Tank
The CDC transfer pump adds this to the SME through the isolation pot block valve
What is Spent Frit or Decon Frit
The SRAT cooling coil return valve will interlock closed on a High Radiation Alarm as well as this other condition.
What is SRAT heating coil steam supple valve open.
This Zone 3 controller becomes inactive for steam valve control when humidity rises above 55%.
What is the Supply TIC
This 210-S ventilation system will interlock the supply fans off if a Zone 2 inlet pressure HIHI is received
What is Regulated Area HVAC
The air separator in the hot water system removes entrained air and directs it to this tank to be vented.
What is Hot Water Expansion Tank
PVV total flow is controlled by this component
What is Air Dilution Valve (CMA)
Nitric Acid can be added to the DWTT for this purpose.
What is Tank Deconning
