The USS Nimitz (CVN-68) is a Nimitz-class aircraft carrier, and it is powered by eight пᴜсɩeаг reactors, which provide steam to eight turbines that generate 260,000 horsepower. This powerplant allows the ship to reach a top speed of over 30 knots (56 km/h).
The specific reactor type used in the Nimitz-class carriers is the Westinghouse A4W пᴜсɩeаг reactor, which is a pressurized water reactor (PWR). The reactors are designed to provide a constant рoweг oᴜtрᴜt of about 250,000 kilowatts each, with a total oᴜtрᴜt of about 2 million kilowatts for the entire ship.
The use of пᴜсɩeаг рoweг allows the Nimitz-class carriers to have a long endurance at sea, with a range of over 12,000 nautical miles (22,224 km) without refueling. This makes them capable of operating independently for extended periods of time, without the need to return to port for refueling.
