Chemistry-Nuclear

Tools

A	B
Nuclear Reactors	use a controlled fission chain reaction
nuclear fuel	U-235 and Pu-239; both are fissionable fuels
moderator	slow down the speed of neutrons so that uranium nuclei can absorb them. Ex,Heavy Water; beryllium, and graphite
control rods	are made of boron and cadmium they can absorb neutrons and therefore control the speed (slow down) & number of neutrons in the reactor
coolants	keep the temperature at a reasonable level during fission reactions; Water, heavy water; molten sodium and molten lithium are examples of coolants
shielding	the shield protects the reactor and people from radiation. Concrete and steel are used for a shield
