In this lesson, our instructor Bryan Cardella gives an introduction on nuclear energy. He discusses nuclear fission, nuclear fuel, electricity production, nuclear reactor basics, water reactors, graphite-moderated and exotics reactors, the pros and cons of nuclear energy, safety issues, and nuclear fission.
Nuclear fission involves the splitting of heavy atomic nuclei to release energy for power. It releases a lot more energy than fossil fuels but the nuclear waste is very dangerous
Some examples of nuclear fuel are: Uranium 235, Uranium 238, and Plutonium 239. Nuclear energy is responsible for approximately 15% of global electricity
Nuclear reactors contain a core, fuel, control rods, a moderator, and coolant. Reactors work with light-water or heavy-water, and they also can be graphite-moderated
Pros for nuclear energy include no air pollution, less carbon release, and low water pollution, but cons include dangerous waste that degrades slowly, expensive decommissioning/shutdowns, and safety/malfunction issues
Chernobyl and Three Mile Island are two of the most famous nuclear disasters in history
Nuclear fusion may prove to be a highly productive way to produce energy in the future
