Capable of traveling at speeds more than 30 knots powered by two A4W nuclear reactors, the Nimitz carriers have proven to play a pivotal role in the service’s fleet. As the Nimitz-class ...

Argonne National Laboratory is developing Gen-IV nuclear reactors, including sodium-cooled fast reactors (SFRs).

Meanwhile, nuclear propulsion is literally the only ... with the latter having enough steam from its two A4W reactors for 104 MW per pair of propellers, leaving a few hundred MW of electrical ...

For propulsion it relies on two Westinghouse A4W nuclear reactors, which power four steam turbines and can generate 260,000 horsepower. Nimitz’s top speed is 31.5 knots. Not bad for a boat ...
