An A4W reactor is a type of nuclear reactor in use aboard the United States Navy's Nimitz-class supercarriers.
The A4W reactor is the nuclear fission pressurized water reactor (PWR) design used in powering U. Navy aircraft carriers.
The A4W reactor is the 4th nuclear fission reactor design for use in powering U. Navy aircraft carriers by a division of the Westinghouse Electric Corporation.

The A3W reactor was intended for use aboard the USS John F. Kennedy (CV-67).
This was a four reactor per ship design to reduce the cost involved in the construction and operation of the USS Enterprise (CVN-65), with its eight reactors.
The return to nuclear power for carriers came with CVN-68 Class with the A4W's two reactor per ship design.

 United States Naval reactor - ExampleProblems.com
United States Naval reactors are given three-character designations consisting of a letter representing the ship type the reactor is designed for, a consecutive generation number, and a letter indicating the reactor's designer.
After the Skate-class vessels, reactor development proceeded and in the USA a single series of standardised designs was built by both Westinghouse and General Electric, one reactor powering each vessel.
A marine reactor was used to supply power (1.5 MWe) and heating to a US Antarctic base for ten years to 1972, testing the feasibility of such air-portable units for remote locations.

 United States Naval reactor
Work on nuclear marine propulsion started in the 1940s, and the first test reactor started up in USA in 1953.
For use in shallow waters such as estuaries and rivers, shallow-draft Taymyr-class icebreakers with one reactor are being built in Finland and then fitted with their nuclear steam supply system in Russia.
Reactor sizes range up to ~500 MWt in the larger submarines and surface ships.

The FMCT would serve as a key building block in the nuclear weapons non-proliferation and disarmament regime by putting a cap on the stocks of fissile material available for nuclear weapons.
Thus the NPT appears to allow any non-nuclear weapon state to launch a military nuclear reactor program and fuel it with weapon-usable uranium removed from under international safeguards, while blocking any effective international effort to verify that no material has been diverted to weapons use.
All nuclear submarines, except those built by Russia, are powered by single reactors; most Russian submarines have two reactors.

 USS Ronald Reagan (CVN-76) - Wikipedia, the free encyclopedia
Reagan the flag that had been flying over the Ronald Reagan when the former president died.
Ronald Reagan displaces approximately 95,000 tons of water fully loaded and has a top speed of over 30 knots, powered by two nuclear reactors driving four screws, and can sail for 20 years before refueling.
She is nearly as long as the Empire State Building is tall at 1,092 feet (333 m) and is 134 feet (41 m) wide at the beam and has a flight deck 252 feet (77 m) wide.

She is powered by two Westinghouse A4W Nuclear Reactor Propulsion Systems, spinning four Main Engine Steam Turbines which spin four shafts, each attached to a single, 25 foot tall, five bladed, bronze alloy screw (propeller).
Her nuclear power plants take care of the electrical and water needs of the ship while other supplies such as food, perishables, and necessities like Toilet Paper are continually replenished by supply vessels which travel with the Vinson where ever she goes.
Another reason we like to use is that Reactor makes all the water… and the Airwing pretty much uses all that water, usually causing water shortages, restricted shower hours and other H2O limitations that pretty much takes the already poor quality of life on the ship and flush it away.

 What is an ELT?
One loop circulates water through the nuclear reactor to transfer the heat generated by the nuclear reaction to a heat exchanger.
Another job of an ELT is to perform radiochemical analyses to determine the level of radioactivity and what isotopes are causing the radioactivity in the primary loop, and also to test the secondary loop to ensure none of the radioactive water has leaked from the primary side to the secondary side.
The third job of the ELT is to monitor the radioactivity released by the nuclear reactor plant.

At that kind of power, the screws are NOT providing thrust, they are spinning in a cloud of steam due to low-pressure cavitation.
They cut a hole in the flight deck and all the decks underneath until they get to the reactor, and then replace the core.
