What are the locations of the main ventilation and AC panel (VP1) and the turbine bldg ventilation panel (VP3)?
VP1: control room
VP3: TB 66’ elev NE
What is the control location of Battery Room 6 supply fan 3HVT*FN12?
local, next to battery room door
What equipment associated with the secondary plants ventilation system have controls located at the Fire Transfer Switch Panel?
HVY*FN2A, service water pump enclosure exhaust fans
The plant has experienced a LOOP. Exhaust fan HVYFN2A for the A service water enclosure is not running. What condition explains why HVYFN2A is not operating?
enclosure area temperature is normal
Describe the AUTOMATIC operation of the Aux Boiler Room Ventilation system.
the supply fans are sequenced based on area temperature, the exhaust fans operate anytime their respective supply fan is operating
What will cause the main steam valve building exhaust fans HVV-FN1A/B AND HVV*FN1C/D to auto stop?
SI signal actuation
What ventilation systems are directly affected by a SI signal actuation?
main steam valve building ventilation system
Where does the ventilation system for potentially contaminated areas of the service building exhaust to?
The unit 3 turbine building stack
Where is VP2 physically located?
CDS Chiller room south end
Where is VP4 physically located?
Aux building 66’ level
Where is VP5 physically located?
Aux boiler room next to hot water heating panel
Where does the service building ventilation fan 3HVE-FN3 take suction from and discharge to?
suction from service building side intake (outside air), discharge to machine shop
Plant is 100% power, outside air very cold. Turbine building ventilation inlet supply dampers start to throttle closed and the recirc dampers start to throttle open. How does the remainder of the turbine building ventilation system respond?
as the inlet dampers throttle closed, various exhaust fans will automatically stop to assist in the temperature and pressure control in the turbine building
