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)
The development of atomic bomb boosted the level of understanding in terms of physics and chemistry of that particular time period. 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”. When the released neutrons attach to other isotopes of Uranium 235, this can result in a chain reaction of fission. For every generation of fission, the amount of fission is doubled, and this resulted in an extreme outburst of energy. The amount of energy released by this process is related to Einstein’s famous equation “E=mc^2” (Wolf).
All these effects were the cause of the discovery of nuclear fission and its properties. Nuclear Fusion Nuclear fusion is the process used by the sun and the stars in our solar system to produce their energy. Fusion involves smashing hydrogen atoms together at high velocities to form helium, and the matter is made into energy.
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).
Second, the potential amount of energy produced by fusion can greatly outweigh the fission. Initially, there are some disadvantages to fusion. The time and money required to develop technology needed to initiate, contain, and sustain a profitable fusion reaction is costly, but the development is still in its early stages and will continue to advance through the next century. Fission readily creates a chain reaction which must be slowed through use of a moderator to avoid core meltdown, while fusion can only be accomplished at temperatures similar to the centre of stars, about 100 million degrees celsius. The components used in fusion exist in the form of plasma where atoms are divided into electrons and nuclei.
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 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.
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.
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.
energy out of a nuclear reaction than we put in. First, the energy per fission
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.
Power from nuclear fusion reactors would be a welcome achievement for the 21st century, and at the current rate of progress it seems likely that before the end of the new century energy will be available from nuclear fusion. It is estimated that it will take over a decade from the time a sustainable fusion reaction is achieved before fusion power will be available for use. But the attention being devoted to research is strong, the experiments are coming closer to fruition, and we are coming closer to having an almost limitless supply of energy.
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
...ion of fusion power plant when the technology has achieved a certain level. 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.
Whilst there are clear arguments for and against nuclear energy, the future is promising; with scientists working on potential breakthroughs such as nuclear fusion, and the design of newer and better and reactors. Nuclear fusion is a reaction which causes the nuclei of atoms to collide and form a new atomic nucleus. It is essentially what heats the sun and stars and would produce no long-lived radioactive waste.22 If scientists could control the process of atomic fusion then it could become a never ending energy source for future use.
