Nuclear fission – the physical process by which very large atoms like uranium split into pairs of smaller atoms – is what ...

Uranium is the primary fuel for nuclear reactors and must be managed properly, in a safe and sustainable manner. Recent annual production of natural uranium world-wide has been between 55,000 and ...

Uranium's use in nuclear weapons is, understandably, the source of the widespread phobia felt by most for uranium. However, it is only weakly radioactive — the half-life of 238 U is 4.468 × 10 ...

That’s where Oak Ridge comes into the picture. By 1939, 91 elements were known to exist, including uranium, which has 92 protons in each nucleus and, at the time, the highest atomic number in ...

Uranium (chemical symbol U) is a naturally occurring radioactive element. In its pure form it is a silver-coloured heavy metal, similar to lead, cadmium and tungsten. Like tungsten it is very dense, ...

Protons are positively charged ... but before the neutrons can collide with fresh uranium nuclei, they need to be slowed down.
