The energy sector is starting to change. In today's modern world, governments around the world are moving away from traditional energy sources, such as burning coal and oil, to the more complex and scientific nuclear energy. This relatively new system uses powerful fuel sources and produces little to no emissions while producing enough energy to meet the world's energy needs (Community Science, n.d.). But while nuclear power appears to be a perfect energy source, no power generation system is without flaws, and nuclear reactors are no exception, with their flaws manifesting themselves in the form of safety. Nuclear reactors use complex systems involving pressure and heat. If any of these systems malfunction, the reactor can leak or even explode, releasing tons of highly radioactive elements into the environment. Anyone who works on or near a nuclear reactor is constantly at risk of being exposed to a nuclear incident similar to those that occurred at the Chernobyl and Fukushima Daiichi power plants. These major accidents, along with unresolved problems related to the design and operation of nuclear reactors, as well as the economic and health problems that nuclear reactors pose, show that nuclear power sources are not worth the service they provide. make and are too dangerous to use regularly. usage.There are two main types of nuclear reactors used around the world, pressurized water reactors, known as PWRs, and boiling water reactors, known as BWRs. The former is more complicated and therefore safer and more commonly used, while the latter presents several unnecessary dangers and is quickly abandoned (Duke, n.d.). In both systems, reactions take place inside a reaction chamber located in the middle of the paper......from http://www.epa.gov/radiation/understand/health_effects.htmlWorld Association nuclear.
