Nuclear reactor basic principles: 1. Neutron induced fission releases energy plus extra "fast" neutrons. 2. "Fast" neutrons are slowed down by a "moderator" such as water or graphite, allowing chain reaction to take place (rapid increase in neutron population). In water reactors, the coolant is also the moderator. 3.
