The reactor vessel is filled with U-235 atom. When a free neutron hits a U-235 atom, the nucleus captures the neutrons and it splits into two lighter atoms and throws off two or three new neutrons (the number of ejected neutrons depends on how the U-235 atom happens to split). The two new atoms then emit gamma radiation as they settle into their new states. Control rods absorb the free neutrons and are raised in lowered to control the reaction. Some of the neutrons are absorbed by the heavy water located in the reactor vessel, which never leaves the vessel. This is all

Unformatted text preview: within the containment structure which is designed to, in any emergency, contain the escape of radiation despite pressures in the range of 60 to 200 psi ( 410 to 1400 kPa ). A loop of fresh water flows thru the reactor vessel to absorb heat. This water absorbs the heat and turns into steam, which turns the turbine producing electricity. The water then flows out into the water source such as a river or lake. Ref: http://en.wikipedia.org/wiki/Containment_building http://science.howstuffworks.com/nuclear-power.htm...
