The fissile material inside a nuclear bomb is primarily isotopes of uranium and plutonium, which are radioactive elements, ...

Three of these will be discussed briefly here. The first, the chemical separation of the fission products of uranium and other fissile elements, is largely a matter of chemical analysis and ...

This is where fast neutron reactors are highly attractive. Fast neutron reactors can also fission other fissile elements, covering the full spectrum of neutron cross sections. TerraPower’s ...

Because of its abundance and its fissile material breeding capability ... “The mineral monazite, which is a major source of rare earth elements, is also a primary source of thorium,” said Mark ...
