Nuclear Energy Nuclear energy is energy produced in a nuclear reaction. This reaction can be naturally produced or can be artificially made. Both fission and fusion are examples of nuclear energy. Fission is taking a large nucleus and splitting it into smaller nuclei, the action of splitting the nucleus into smaller nuclei causes mass amounts of energy to be emitted from the reaction. Fusion amounts for mass amounts of energy produced around the world. This form of nuclear energy is the most efficient in terms of use of energy to production of energy. Fission generally involves the use of uranium, this is due to it's large weight (of the nucleus). While fusion is the joining of two smaller nuclei and forming a larger nucleus. This reaction is impractical in terms of energy production. This is due to the fact that the action of fusion requires more energy to occur than it would produce after the fusion has occurred, but when done correctly the energy produced is unbelievable in comparison to fission. Uses of Fission include power reactors and nuclear weapons. Neutron Fission Power Reactors- this involves the fission of Uranium with nuclear waste and nuclear material as its byproducts. One of the byproducts is Plutonium which is commonly used in nuclear weapons. Also fission is used for Nuclear Weapons- what is meant by this is that the byproduct of fission allows for nuclear material to be produced as well as producing nuclear waste that can allow for nuclear weapons to be manufactured. The issue with the nuclear waste produced is that there are no restrictions or preventative measures that are enforced or in place to help with the environment. Fusion as an energy source, If fusion could be completed without usin... ... middle of paper ... ...oving and or disproving previous theories. 2000-Present- Andrea Rossi- (Not really cold fusion) but he has developed a device called an E-Cat that involves Nickel and Hydrogen reactions. These small nuclear reactions emit rather significant amounts of energy. Rossi himself doesn’t want to associate his device with “Cold Fusion’ due to the fact that the field itself has such negativity involved. (Thanks Nuclear Physicists) Another important thing to mention is that no radioactive materials are used and or produced, only metals like Nickel and some Copper are produced. Any radiation that is produced in the nuclear reaction will only last for a maximum lifetime of 20 minutes, this is due to the fact that the radiation itself is thermalized. (Generally this reaction is considered “Cold Fusion” but Rossi believes that it is actually Low-Energy Nuclear Reaction or LENR)
Physicists started to realize that stable nuclei can be converted to unstable nuclei. Through such process, they discovered that heavy nuclei can undergo nuclear fission. While testing, they added a neutron to an isotope of Uranium 235. This resulted Uranium 235 to become unstable and break down into Barium and Krypton, releasing two to three more neutrons. The breakdown of Uranium 235 is called “fission”.
Nuclear energy is used today for energy supply and about 15% of the world’s energy comes from nuclear power plants some forms of medicine such as nuclear medicine rely solely on nuclear technology. This technology was developed through the process of creating the first atomic bomb and would not exist if not for the advancements made during the Manhattan project.
Radioactive Waste One of the most talked about opposition to nuclear fission is the radioactive waste it produces. Radioactive waste is what is left behind after using a reactor to make electricity. There are two levels of waste, low and high, but both are regulated by the Department of Energy and the Nuclear Regulatory Commission. High level waste is made up of fuel that’s been used directly in the reactor, which is highly radioactive but can still be disposed of. Low-level waste is the contaminated items that have been exposed to radiation.
Nuclear energy must be a consideration for the future with the rapidly depleting supply of fossil fuels. This type of energy can be created through nuclear fission and nuclear fusion. Nuclear fission is the splitting of a heavy atom into two or more parts, releasing huge amounts of energy. The release of energy can be controlled and captured for generating electricity. Nuclear fusion involves bombarding hydrogen atoms together to form helium. In the long run, nuclear fusion has greater potential than fission.
Currently, plants use fission reactions, which is the bombardment of atoms with neutrons to split atoms into new materials, releasing the energy which we have all come to rely on. Fusion is essentially the opposite of fission. Fusion is the combination of atoms to make new elements, what is happening at the core of our sun currently. When atoms are fused, a massive amount of energy is released, making the cost of producing nearly free once fusion is obtained. One other large advantage of fusion energy is the by-products produced by the chain reaction in fusion. The second most abundantly used power source in fission reactors behind uranium is plutonium. Plutonium could be created by the fusion reactions, giving people not only energy from the initial reaction, but even more fuel to use for fission reactors
Nuclear energy is produced during the process named nuclear fission or nuclear fusion. The development of nuclear energy started in the 20th century and there is now worldwide recognition for using nuclear energy. Popular countries that operates nuclear power are United States, France, Japan, and Russia, the nuclear energy generates up to 6% of the world’s electricity supplies. Even though the energy is mostly used by many countries, but it may causes side effect to the living things in the environment. (WNA, 2012)
The Cold War was a political standoff between the Soviet Union and the United States that again created a new worldwide nuclear threat. The destructive potential of nuclear weapons has created a global sweep of fear as to what might happen if these terrible forces were unleashed again. The technology involved in building the first atomic bombs has grown into the creation of nuclear weapons that are potentially 40 times more powerful than the original bombs used. However, a military change in strategy has come to promote nuclear disarmament and prevent the usage of nuclear weapons. The technology of building the atomic bomb has spurred some useful innovations that can be applied through the use of nuclear power.
A. Attention Material: Have you ever thought about energy? Where it comes from and how it powers things? Nuclear energy is one of the many types of energy sources in the world today. It is a non-renewable resource such as coal and natural gas. The first nuclear reactor ever created by man was built in December of 1942. The discovery of building a nuclear power plant was discovered over 150 years ago (Nuclear Power: Villain or Victim?, p. 15).
Compare and Contrast Nuclear Energy and Alternative Energy. Standard Number Science 3.4. Today, our society is using more energy than ever. With the increase in demand for energy, problems are presented that have to be addressed.

In 1945, when the Americans bombed Hiroshima, Japan, approximately 140,000 men and women were instantly killed by the effects of American nuclear defense. With such extreme brutality and force how many people must die for one to finally realize the strengths of nuclear bombs and what damage they can cause. Nuclear weapons should be outlawed because they kill thousands of innocent humans at a time, destroy the environment, and inviolate human’s right to moral and personal freedoms.
The nuclear age began before the Cold War. The United States was the first country to develop the nuclear weapons through the Manhattan Project during World War II against Axis power. The US ended the war by dropping nuclear bombs on the cities of Hiroshima and Nagasaki in Japan. Nuclear bombs are extremely powerful. It could destroy an entire city and kill tens of thousands of people. The only time nuclear weapons have been used in war was at the end of World War II against Japan. Although the Cold War was predicated
Nuclear fusion occurs when two atomic nuclei collide with enough energy to bind together to form one nucleus. Nuclear fusion occurs in the core of our sun, and is the source of its tremendous heat. In the sun hydrogen nuclei, single protons, fuse together and form a new nucleus. In the conversion, a small amount of mass is converted into energy. It is this energy that heats the sun.
Nuclear energy is generated by a process called fission. Fission occurs within the reactor of a nuclear power plant when a neutron is fired at an atom of uranium causing it to split and release subsequent neutrons.1 These are able to crash into other uranium atoms causing a chain reaction and releasing a great deal of heat energy.

This level will be reach with free market and patents right, which will create incentive for scientist to make innovation. Hopefully, countries, in the future, will find co-operating relationship’ among each other and solve environmental problems.
