REACTOR
| Question | Answer |
|---|---|
| Hyman G. Rickover | - Father of Nuclear Navy - Achieved the rank of Admiral - Served 63 years of active duty |
| USS Nautilus (SSN-571) | - First Nuclear Powered Vessel - Submarine - Commissioned in 30 September 1954 - Active duty 26 years - Transmitted the famous quote, “Underway on Nuclear Power” - First submarine to complete a submerged transit to the north pole |
| USS Long Beach (CGN-9) | - First Nuclear Powered Surface Combatant - Guided Missile Cruiser - Commissioned on 9 September 1961 - Active duty 34 years - Served in the Vietnam War |
| USS Enterprise (CVN 65) | - First Nuclear Powered Aircraft Carrier - Commissioned on 25th November 1961 - Active duty 51 years - Had 8 reactors - 8th US Naval Vessel to bear the name “Enterprise” |
| Advantages of Nuclear Power over Fossil Fuel Propulsion Plants | - A reactor can provide power for approximately 25 years before needing to be refueled - Better visibility for pilots landing due to no exhaust from the propulsion plants - Less underway replenishments |
| What does Reactor Department do for the ship? | - Provide propulsion to move the ship - Provide electricity to power the ship and launch aircraft - Provide fresh water to the ship and the crew |
| Number of RX’s onboard | 2 |
| Type of RX | A1B: A = Aircraft Carrier, 1 = 1st Model, B = Bechtel (Manufacturer) |
| Purpose of A1B Nuclear Reactor | - Generates heat by fissioning atoms of nuclear fuel - Type of fuel: Uranium |
| Purpose of RX Coolant System | - Transfers the heat from the nuclear reactor to the Steam Generators |
| Purpose of the Steam Generator | - Converts heat from the reactor coolant system to steam |
| Purpose of the Main Steam System | - Transfers steam created in the Steam Generators to the Main Turbine Generators (MTGs) and Main Propulsion Units (MPUs) |
| Purpose of Main Turbine Generators (MTGs) | - Utilizes steam created by the nuclear reactor to generate 13.8kV electricity - Primary source of electrical power for the ship - Can provide 26 Mega Watts(MW) of power each - 4 onboard |
| Purpose of the Trip Throttle Valve (TTV) | - Secures steam flow to the MTGs |
| Purpose of Emergency Diesel Generators (EDGs) | - Utilizes diesel fuel to generate electrical power for the ship - Emergency source of electrical power for the ship - Fuel source - JP-5 - Can provide 4 MegaWatts(MW) of power each - 4 onboard |
| Purpose of the Electric Plant Control Panel (EPCP) | - Monitors and controls the ship’s electrical distribution system - 2 EPCPs o 1 in Central Control Station (CCS) (Primary) o 1 in Enclosed Operating Station (EOS) (Secondary) - Watchstander who stands watch at EPCP : Electrical Operator |
| Purpose of Main Propulsion Units (MPUs) | - Utilizes steam created by the nuclear reactor generate horsepower to propel the ship - Can propel the ship in excess of 30 knots - 4 onboard |
| Purpose of the Main Engine Guard Valve (MEGV) | - Secures steam flow to the MPUs |
| Purpose of Potable Water Units (PWUs) | - Convert seawater to fresh water through the process of reverse osmosis - 4 onboard - Ability to make 125,000 gallons/day (500,000 gallons/day utilizing 4 PWU’s) |
| Reactor is Critical | Reactor is online and stable |
| Reactor Scram | Emergency shutdown of a reactor |
| Trailed Shaft | No steam applied to the MPU and the shaft is spinning with movement of the ship; reduces ship’s maneuvering capability |
| Locked Shaft | No steam applied to the MPU and the shaft is locked in place; greatly reduces ship’s maneuvering capability |
| Cross-connected Steam Plants | One reactor plant is providing steam to both propulsion plants |
| Dead-in-the-Water (DIW) | Both reactors are offline with no propulsion to the ship and electrical power is limited to the EDGs |
| Thermoluminescent Dosimeter (TLD) | - Monitors the amount of radiation received - Required to be worn at all times when entering a Radiation Area - Worn on the waist, facing forward |
| Identification of Radiological Signs or Radiological Material | - Yellow and Magenta signs / bags |
| Actions if Radiological Signs and/or Radiological Material is unattended | WIN: - W – Warn other personnel - I – Isolate the area - N – Notify central control |
| Reactor Watches | Locations of Reactor Watches (4): - Central Control Station (CCS) - Enclosed Operating Station (EOS) - Engine Room - Emergency Diesel Spaces |
| Reactor Department Principle Assistants: | 6 CRA – Chemistry / Radiological Assistant MPA – Main Propulsion Assistant REA – Reactor Electrical Assistant RMO – Reactor Maintenance Officer RTA – Reactor Training Assistant RCA – Reactor Controls Assistant |
| Reactor Department Divisions: | 9 RE – Reactor Electrical RC – Reactor Controls RL – Reactor Laboratories RXDC – Reactor Damage Control RA – Reactor Auxiliaries RT – Reactor Training RN – Reactor Networking RM – Reactor Mechanical RXADN.- ADMIN |
| Main Turbine Generators (MTGs) | - 4 onboard o 1 in #1 Engine Room, STBD side o 4 in #1 Engine Room, PORT side o 2 in #2 Engine Room, STBD side o 3 in #2 Engine Room, PORT side |
| Emergency Diesel Generators (EDGs) | - 4 onboard o 1 in #1 Emergency Diesel Generator Room, STBD side o 2 in #1 Emergency Diesel Generator Room, PORT side o 3 in #2 Emergency Diesel Generator Room, STBD side o 4 in #2 Emergency Diesel Generator Room, PORT side |
| Main Propulsion Units (MPUs) | - 4 onboard o 1 in #1 Engine Room, STBD side o 4 in #1 Engine Room, PORT side o 2 in #2 Engine Room, STBD side o 3 in #2 Engine Room, PORT side |
| Potable Water Units (PWUs) | - 4 onboard o 1 in #1 Engine Room, STBD side o 4 in #1 Engine Room, PORT side o 2 in #2 Engine Room, STBD side o 3 in #2 Engine Room, PORT side |
| Rates in RX Dept | 6 EMN – Electricians Mate Nuclear MMN – Machinist Mate Nuclear ETN – Electronics Technician Nuclear MM – Machinist Mate EN – Engineman YN – Yeoman |
