Who is the roving supervisory watch stander in charge of the propulsion plant?
Propulsion Plant Watch Supervisor (PPWS)
Who is in charge of both propulsion plants and engineering spaces?
Engineering Officer of the Watch (EOOW)
Who is responsible for the electric plant?
Load Dispatcher
Who does the EOOW report to?
OOD
What is SCRAM?
Rapid shutdown of the reactor
Describe the reactor at “CRITICAL”
Operating and producing power
What does it mean for the reactor to be “shutdown”?
Rods are inserted but no heat is being produced
What do cross-connected steam plants mean?
Steam is being supplied to both propulsion plants from one reactor
What is Restricted Maneuvering doctrine?
A state that the ship operates in to provide maximum propulsion, electrical, and navigational reliability
What does MTT stand for?
Mobile Training Team
What does ORSE stand for?
Operational Reactor Safeguards Exam
What does MTT and ORSE do?
Evaluates Reactor Department’s ability to safely operate the reactors
What does SPM stand for?
Steam Plant Manual
What does RPM stand for?
Reactor Plant Manual
What type of fuel do the reactors use?
Enriched uranium
What does A4W stand for?
Aircraft Carrier Core, 4th Design, Westinghouse
What type of design is the reactor?
Pressurized Water
How does the reactor produce usable energy?
Heat produced from fission is used to create steam; steam powers the turbines for electricity and propulsion
What are the advantages of reactor power over fossil fuel?
-refueled only twice in a ship’a life-allows more fuel to be carried on board-does not release exhaust in the air that would make it harder for planes to land
What does RC stand for?
Reactor Controls
What does RE stand for?
Reactor Electrical
What does RL stand for?
Reactor Laboratory
What does RM stand for?
Reactor Mechanical
What does RA stand for?
Reactor Auxillaries
Classify our type of reactor
-Double reduction-Double helical-Articulated-Locked train-Folded
What does GV stand for?
Guard Valve
What does Trailed Shaft mean?
Main engine guard valve is shut
What does ABT stand for?
Automated Bus Transfer
What does MBT stand for?
Manual Bus Transfer
Why do we use a 4160V system?
Higher voltage, lower current, less equipment
What does EPCP stand for?
Electrical Plant Control Panel
What is the Voltage Regulator Unit?
Regulates voltage and provides voltage droop characteristic to share reactive loading
How does nuclear fission produce energy?
Neutron absorbed by uranium splits into neutrons, protons, and gammas
How many HPAC’s do we have?
4
How many reboilers do we have?
2
Where are the reboilers located?
1A/4B shaft alleys
Why do we use reboilers?
To prevent contamination of the propulsion plant
What are some loads off the reboilers?
-laundry steam-galley steam-hot water heaters
How do we make potable water?
Distilling Units
Classify the D/U’s
-6 stage-flash type-LP-100,000GPD
How many D/U’s do we have?
4
Where are the D/U’s located?
1&2 = MMR #13&4 = MMR #2
How much water is used by the propulsion plant per day?
200,000 gallons
How do we produce electrical power on board?
Ship’s Service Turbine Generators
How many SSTG’s do we have?
4
Where are the SSTG’s located?
1&2 = MMR #13&4= MMR #2
What are the SSTG’S rated at?
4160V / 8MW
What is the back up to the SSTG’S?
Emergency Diesel Generators
How many EDG’s do we have?
4
What is the primary purpose of the EDG’s?
Supply power to the reactor pumps
What are the EDG’s rated at?
4160V / 2MW
How many main engines do we have?
4
Explain the responsibilities of Reactor Controls
