Nuclear energy comes from the nucleus of an atom. The source, or fuel, of nuclear energy is most commonly Uranium 235 Nuclear energy can be converted into electricity, as a secondary energy source, which flows through power lines and other sources to be transmitted to your home. Fission means to split apart. Inside the nuclear reactor, uranium atoms are split apart in a controlled chain reaction. A slow neutron can be captured by a uranium-235 nucleus, and leave it unstable when undergoing nuclear fission. If a neutron goes too fast, it will not be captured in the nucleus, so neutrons must be slowed down to increase their chance to the captured in the reactors. The pressurized water reactor is better to the environment than the boiling water reactor because more of pressurized water reactor is enclosed in a containment structure, which produces less radiation to the surrounding area. Uranium is found in uranium mines. Searching for uranium is sometimes easier to find than for other mineral resources because the radiation signature of uranium's decay products allows deposits to be recognized and charted from the air. The energy released by the fission that takes place in a nuclear reactor is converted and generated into electricity. Both fission and fusion are actively used in providing power for the missions in space. They create higher velocities that increase the speed of rockets. Nuclear energy can be used by archaeologists, geologists and anthropologists in defining the age of rocks, insects, etc. It can be used in the treatment of cancer through the use of radiotherapy. Nuclear Energy can also be used in Food and Agriculture, Sterilization, Tracing Pollutants, Detecting Leaks in Pipelines, and Power Sources. http://ww... ... energy than what the lasers originally shot at the target. Preparing for a typical fusion reaction takes weeks, but the reaction is completed in less than one-billionth of a second. At the core of the reaction, the pressure is 150 billion times atmospheric pressure. "The density and temperature of the plasma created is nearly three times that at the center of the Sun," Omar Hurricane wrote. Does not emit greenhouse gases Creates a huge amount of energy in small amounts of fuel Can commonly find the fuel to use fusion Does not emit as much radiation as fission We haven’t been able to have a controlled reaction be able unleash huge amounts of energy on earth. We need to have a reaction where we get more energy from fusion than how much energy we need to create it. It only occurs at extremely high pressure and temperatures. Reaction lasts a very short time.
