Reactor Flashcards
What does it mean when there reactor is critical?
The reactor core has just enough fission activity producing neutrons to keep the reaction rate constant
What does the reactor use as a fuel source?
Enriched uranium-235
What is a reactor scram
The reactor is shutdown by insertion of all control rods
How much power does the reactor generate?
550 MW
State the purpose of the reactor
Reactors create heat which is transmitted to the steam generators
State the purpose of the steam generators
Takes the heat from the reactor and make steam which is then sent to various loads throughout the ship
State the steam loads which receive steam from the steam generators
- Main engines
- Ship service turbine generators
- Coolant turbine generators
- Catapults
- Reboilers
- Distilling unit
State the purpose of the reboilers
They make steam which is distributed throughout the ship and used for various reasons
How many reboilers do we have and what are their capacity?
2; 80,000 lbm/hr
Where are the reboilers located
#1 reboiler is in 1A shaft alley #2 is in 4B
What is the purpose of the distilling units
Take seawater, flash it via steam and create potable water or feed water
How many distilling units do we have? Where are they located?
4; 1&2 in 1MMR 3&4 2MMR
Define feed water
Extremely high purity water for reactor n steam plant use
Define fission
The spontaneous or induced splitting of atomic nucleus into smaller parts
