Nuclear systems powered by 242m Am require less fuel by a factor of 2 to 100 compared to conventional nuclear fuels. Fission-fragment rocket using 242m Am was proposed by George Chapline [ 43 ] at Lawrence Livermore National Laboratory (LLNL) in 1988, who suggested propulsion based on the direct heating of a propellant gas by fission fragments ...

After the ban of nuclear weapons in space by the Outer Space Treaty in 1967, nuclear power has been discussed at least since 1972 as a sensitive issue by states. [8] Space nuclear power sources may experience accidents during launch, operation, and end-of-service phases, resulting in the exposure of nuclear power sources to extreme physical conditions and the release of radioactive materials ...
The United States Navy at one time had nuclear-powered cruisers as part of its fleet. The first such ship was USS Long Beach. Commissioned in 1961, she was the world's first nuclear-powered surface combatant. [25] She was followed a year later by USS Bainbridge.
USS Nimitz (CVN-68), lead ship of the Nimitz-class of nuclear-powered aircraft carriers A Delta-class nuclear-powered submarine. Nuclear-powered vessels are mainly military submarines, and aircraft carriers. [1] Russia is the only country that currently has nuclear-powered civilian surface ships, mainly icebreakers. The US Navy currently (as of ...
Nuclear scientists and engineers often need to know where neutrons are in an apparatus, in what direction they are going, and how quickly they are moving. It is commonly used to determine the behavior of nuclear reactor cores and experimental or industrial neutron beams. Neutron transport is a type of radiative transport.
The single-most important thing to remember if a nuclear bomb is supposed to explode, he says, is to shelter in place. "There were survivors in Hiroshima within 300 meters of the epicenter ...
E1 is produced when gamma radiation from the nuclear detonation ionizes (strips electrons from) atoms in the upper atmosphere. This is known as the Compton effect and the resulting current is called the "Compton current". The electrons travel in a generally downward direction at relativistic speeds (more than
