100,000 gal per unit
400,000 gal all together

Question 7

Electric Plant

Answer 7

At sea the SSTGs supply power.

Inport high voltage shore power lines supply power

Question 8

Critical

Answer 8

Self sustaining nuclear fission process in other word the reactor is at steady power

Question 9

Dead In Water

Answer 9

Loss of both reactors

Question 10

Cross connected steam plants

Answer 10

One reactor supplies to both steam plants

Question 11

ORSE

Answer 11

Operational Reactor Safeguard Exam

Question 12

Fission Process

Answer 12

Neutrons mashes into uranium
Splits into gammas or fission fragments
Then heats to cause more fissions

Question 13

Restricted Maneuvering Doctrine

Answer 13

• Unrep
• GQ
• Man Overboard
• Restricted Waters
• Coming in and out of port
• COs Discretion

Question 14

Steam Process

Answer 14

Reactor heats primary coolent
Primary coolant heats secondary water
Secondary water turns to steam
Steam performs work on major steam loads
Steam is condensed into water
Water is fed to DFT
Water is fed through main feed pumps
Main feed pumps feed back to STGs
