What are the advantages and disadvantages of nuclear power and usage? Even though nuclear waste can be bad and power plants can go wrong if not managed correctly, nuclear power and usage should be used. It should be used because nuclear energy helps a lot of people with cancer, we can defend our country, and nuclear power is a good way to supply energy without using fossil fuels! Nuclear energy has the lowest impact on Earth since it doesn’t release any deadly gases like carbon dioxide and methane which are responsible for the greenhouse effect. Nuclear Energy does release some gases while transporting it and extracting the energy from uranium.
During the fusion process there is a light nuclei, and this has an advantage over fission because light nuclei are easier to obtain because there is more of them and then end result is light and are more stable and not as heavy and radioactive. Then we will take the energy through the reactor and the heat will then be used to produce electricity. The only disadvantage of using nuclear energy is that it is not an unlimited resource as it requires uranium and plutonium and those two products are themselves limited. Although we have just now started using these materials they will soon run out do to our increase in populations and electronic consumption. But nuclear energy for now is a good substitute for electricity until we can come up with a better way to make that energy in the future.
However, nuclear power is a reliable source of energy because it has no carbon emissions, energy is available at any time, little fuel is needed for a lot of energy, and as time goes on, it is becoming safer and safer. A major advantage of nuclear power is that it does not release any carbon emissions like fossil fuels (“Advantages and Disadvantages of Nuclear Energy”). The burning of fossil fuels releases greenhouse gases, which is what causes global warming. The transition to using fewer resources like these and using more nuclear power for energy will benefit the environment greatly. Arctic environments will not suffer, and ocean levels won’t rise.
In a Pressurized Water Reactor (PWR) this heat circulates in a pool of radioactive water, which transfers its heat to a second pool of water that produces steam, which runs through a turbine and turns the generator, turning mechanical energy into electrical energy. Uranium-235 is the ideal fuel, because it is readily available and reactions with it release neutrons that continue the change reaction. However, Uranium straight from the ground is 98% Uranium-238, which much be enriched to at least 5% Uranium-235 for fission to occur. Further challenges include maintaining a critical mass, or the amount of fissionable required... ... middle of paper ... ...ear power needs to be rethought. References Alters, Sandra M. (2009).
Nuclear energy is very safe when handled correctly and with great precaution, “the process to generate nuclear energy is one of the cleanest processes, and makes lowest impact on the environment. It is due to the fact that nuclear plants do not emit any harmful gases like carbon dioxide, nitrogen oxide and sulfur dioxide, produced from the conventional electricity power plants that threaten atmosphere by increasing global warming” (Gupta). These nuclear power plants can produce large amounts of energy with only a few resources being used. These power plants only require a little amount of fuel to power it and “it is estimated the amount of energy released in a nuclear fission reaction is ten million times greater than the amount released in burning a fossil fuel atom”(Maehlum). The uranium used to power the reactors in the plants produce way more energy than fossil fuel where “one ton of uranium can produce energy that is more than that of several million tons of coal and oil”
A fusion reaction is measured in MeV, million of electrical volts. A single deuterium- tritium reaction can contain 14 MeVs. Another advantage of nuclear fusion is that it does not pollute the air with carbon dioxide like burning fossil fuels. It also does not pollute the air with radioactive chemicals like nuclear fission. A third reason nuclear fusion is better is because nuclear fusion has a very small chance of serious nuclear mishaps.
The nuclear waste is unlikely to expose to people, because there are guards who will protect the waste in where it is stored at. Lastly, there are some bad things about nuclear energy, but it is not much compared to the good things. In conclusion, nuclear energy is an efficient source to produce electricity. With nuclear energy, over million tons of carbon dioxide are reduced in the U.S. Nuclear energy also help reduce the amount of land use to produce electricity and get more free land for other purposes. According to the low accident rate of nuclear energy, nuclear power plants would be consider as a safe way to produce electricity.
Even though uranium may not be renewable, there are much smaller amounts that are being used by it compared to coal, gas and oil. Unlike fossil fuels that release harmful gases when we burn them, this causes global warming because the gases will capture heat around the earth. This is not produced by nuclear power plants.

With the depleting sources, nuclear energy is the only energy source that can satisfy global demand, effectively replace fossil fuels and it is more sustainable than other energy sources. Nuclear energy has no greenhouse or acid rain effects and the fuel is inexpensive.

But there are so many bad sides of using coal and there is better alternative for coal, the nuclear power. Since energy from coal is not affordable for many people in the Philippines and cost tremendously to environment through causing greenhouse effect and destroying ozone layer.
These are the pros and cons of nuclear energy. So we can harness the energy that is produced through the process of fission and generate electricity. All this is done in nuclear reactors. A core of Uranium is at the center of the reactor. Uranium, Uranium-235 is the preferred isotope, is used because it under goes fission naturally and at a slow rate.
