Radioactive carbon dating flaws
When a control rod is inserted deeper into the reactor, it absorbs more neutrons than the material it displaces—often the moderator.
This action results in fewer neutrons available to cause fission and reduces the reactor's power output.
The heat is carried away from the reactor and is then used to generate steam.
Most reactor systems employ a cooling system that is physically separated from the water that will be boiled to produce pressurized steam for the turbines, like the pressurized water reactor.
Some reactors are used to produce isotopes for medical and industrial use, or for production of weapons-grade plutonium. As of April 2014, the IAEA reports there are 435 nuclear power reactors in operation, in 31 countries around the world. A neutron is absorbed by the nucleus of a uranium-235 atom, which in turn splits into fast-moving lighter elements (fission products) and free neutrons.A nuclear reactor, formerly known as an atomic pile, is a device used to initiate and control a sustained nuclear chain reaction.
