Can aircraft be nuclear powered?

The only US aircraft to carry a nuclear reactor was the NB-36H. The reactor was never actually connected to the engines.

Is a nuclear powered train possible?

The possible benefits of having nuclear powered trains include economic and transport efficiency, lower emissions, and ease of hauling cargo over great distances. Rail is already the greenest method of long-haul transportation.

Do nuclear powered cars exist?

To this day, the closest we’ve ever come to a nuclear car is the Ford Nucleon, a 1958 scale model concept car that would’ve used a nuclear reactor paired with a steam engine (much like nuclear submarines or icebreakers).

Can we build nuclear cars?

While small-scale thorium-powered nuclear reactors are theoretically possible, none have been designed that could fit in a car. Stevens’ system uses a thorium-powered laser to turn water to steam, which could be used in a car.

What are the advantages of nuclear-powered airplanes?

The advantages of nuclear-powered airplanes mirrored those of nuclear submarines. Nuclear submarines did not need to surface for fuel, and nuclear airplanes would not need to land.

How did the Air Force develop nuclear-powered planes?

Under the new Aircraft Nuclear Propulsion program, Air Force engineers immediately went to work, developing three experimental engines (two of which are pictured below). By 1951, they settled on a method for directly transferring heat from a reactor and using it to propel an aircraft, described thusly in a 1963 governmentreport:

Will nuclear power ever take wing in aviation?

Given the current regulatory attitude toward grounded nuclear energy, the ubiquity and safety of fossil fuel-powered flight, and advancements in electric aircraft, it’s difficult to imagine that nuclear power will ever take wing. (Images: USAF, Wtshymanski)

Why can’t we fly over a nuclear reactor?

To protect the crew from radioactivity, the reactor needed thick and heavy layers of shielding. But to take off, the plane needed to be as light as possible. Adequate shielding seemed incompatible with flight. Still, engineers theorized that the weight saved from needing no fuel might be enough to offset the reactor and its shielding.
