A nuclear reactor is a device by which energy is produced as the result of a nuclear reaction, either fission or fusion. ... At the present time, all commercially available nuclear reactors make use of fission reactions, in which the nuclei of large atoms such as uranium (the fuel) are broken apart into smaller nuclei,

The key to initiating a fusion reaction is for the nuclei that are to fuse to collide at very high velocities, thus driving them close enough together for the strong (but very short-ranged) nuclear forces to overcome the electrical repulsion between them.

But the fuel has enough U-235 to produce a chain reaction. Nuclear fuel requires special processing before and after it is used. The processing begins with the mining of uranium ore and ends with the disposal of ... Here’s a diagram of a NUCLEAR REACTOR to show the basic theory behind how it works in our industries...

The theory behind nuclear fission is quite simple. Particles in atoms (protons, neutrons) always tend to organise ... This means that once a reaction of this type is started, it would accually grow in intensity. It is for this reason that nuclear fission can be readily used as a very highly effective energy source.

In fact, Rutherford was able to demonstrate, in 1919, that alpha particle could knock protons out of nitrogen nuclei and merge with what was left behind. The most common isotope of nitrogen is nitrogen-14, ... It follows then that Rutherford had successfully carried through the first man-made nuclear reaction:

Looking back from the vantage point of a post-Three Mile Island, post-Chemobyl world, people sometimes wonder why we ever went ahead with nuclear power. ... The control rods absorb neutrons and stop the chain reaction. Unfortunately, the core stays hot even after the chain reaction is killed since once a reactor has operated...
