Nuclear Energy Essay Sample
Humanity requires more and more energy. The predictions made about the growth of development of new energy technologies, and the energy consumption were not correct.
The energy consumption level is growing much faster than predicted. At the same time, the new sources of energy on an industrial scale and at competitive prices will start working no earlier than A shortage of fossil energy gets sharp.
The possibility of building new hydropower plants is also very limited. The fight against the "greenhouse effect" restricts the burning of oil, gas and coal in thermal power plants. The solution may be an active development of essay nuclear energy energy, one of the youngest and fast-growing sectors of the global economy. Nowadays, many people say that nuclear energy is discredited. People have the impression that after the tragic events at nuclear power plants in Japan, most countries refuse to develop this area of energy.
However, even Japan, which recently said about the closure of all nuclear power plants in the country, changes its mind. The Government of Japan has declared its readiness to review the plans for the use of nuclear power in the direction of the continuation of their exploitation. Nuclear energy is the energy contained in the nuclei and released in nuclear reactions. It refers to the long-term and relatively cheap forms of energy. This energy is released as a result of an internal restructuring of atomic nuclei.
Nuclear energy can be obtained from nuclear reactions or radioactive decay of nuclei. The main methods of nuclear energy production are the fission of heavy nuclei and the fusion of light nuclei, essay nuclear energy.
The latter process is also known as thermonuclear reactions. Division occurs by dividing of one atom by two. The splitting happens when the atoms bombarded by particles essay nuclear energy atoms, such as neutron. The heat released by cleavage is used to generate steam directed to turbines that generate electricity basically the same manner as in thermal power stations. Not every atom bombardment leads to its breakdown. Most of the atoms cannot be split, essay nuclear energy.
But the atoms of uranium and plutonium under appropriate conditions decompose radioactively. One type of uranium is uranium When uranium is bombarded with neutrons it splits into two parts. The products of decay are usually two fission products, such as krypton or barium, and two or three neutrons. It takes time no more than few seconds and is accompanied by the emission of three neutrons. The increase in the number of neutrons in the fission process opens the possibility of a chain reaction of nuclear fission.
One kilogram of uranium releases a million times more energy than is released during the combustion of one kilogram of coal. A small piece of uranium can provide the work of the whole ocean ship, aircraft or generator.
In the synthesis reaction, two atoms fuse together and form a single atom. Enormous energy releases as heat when connecting atoms. Most of the solar energy is the result of a fusion reaction that occurs in the sun.
These reactions usually occur with the release of energy, essay nuclear energy, as formed by the merger of heavier nucleus nucleons are bound stronger.
They have, on average, greater energy than in the initial fusing nuclei, essay nuclear energy. The excess total energy of the nucleons, in this case, essay nuclear energy, is released in the form of kinetic energy of the reaction products.
These reactions occur at high temperatures since the merger of light nuclei must approach to a distance equal to the radius of the nuclear forces of attraction, essay nuclear energy. Positively charged nucleus experience the Coulomb repulsion when they are outside of the nuclear forces of attraction. Only the cores that are flying toward each other at high speeds, such as included in the very hot environments or specially essay nuclear energy ones, are capable to overcome this repulsion.
The rate of a fusion reaction is extremely small at energies below a few KeV, but it is growing rapidly with the growth of the nuclear kinetic energy, entering into the reaction. Considering the dependence of the specific nuclear binding energy of the mass number Essay nuclear energy the number of nucleons in the nucleus is an explanation of the appearance of the two main sources of nuclear energy. Specific binding energy ε shows what the average energy is necessary to provide to the individual nucleons to release all the nucleons from this core.
Because of this dependence on ε and A there are two ways to obtain the above-mentioned nuclear energy. In both processes, a transition to the nuclei in which the nucleons bound stronger is made, and a part of the nuclear essay nuclear energy energy is released.
The fission method of energy production is used in a nuclear reactor and nuclear bomb. Nuclear fusion is used in the developing of a thermonuclear reactor and a thermonuclear bomb. These ways of energy production are a record in terms of energy per unit mass of fuel.
For example the complete fission of 1 gram of uranium releases energy around 10 11 J. That is roughly the same essay nuclear energy the explosion of 20 kg of trinitrotoluene. Therefore, essay nuclear energy fuel is 10 7 times more efficient than chemical fuel.
Nuclear power plants pollute the environment, as well as power plants running on fossil fuels. If emissions of conventional essay nuclear energy plants include the already familiar to us chemicals, nuclear power plants emissions include radioactive elements, essay nuclear energy, which are almost entirely a product of fission reactions.
The cleavage products contain radioactive isotopes of krypton, essay nuclear energy, xenon, cesium, rubidium, barium, strontium, iodine and bromine isotopes of hydrogen and tritium. Other isotopes generated in the cooling essay nuclear energy, including isotopes of argon, fluorine, hydrogen and oxygen, essay nuclear energy. A number of other isotopes produced essay nuclear energy materials surrounding the reactor core.
In general, nuclear power is a highly effective energy source. Under normal conditions, essay nuclear energy, nuclear power stations do not generate significant air pollution. They are able to meet the growing future energy needs replacing fuels, highly polluting the atmosphere and storing them as raw material for industry.
On the other hand, the possibility of accidental discharge of radioactivity is still a concern, so that the popularity of nuclear power stations is rather low, which hampers the implementation of the program of nuclear energy in North America and Europe.
In addition, uranium reserves, as well as oil and coal are limited and are likely to be depleted in a few centuries. Until then, nuclear power should be studied deeply and considered as a significant energy source.

Nuclear Energy is the energy released during nuclear fission or fusion. Nuclear fusion and fission is the joining and splitting of the nucleus of an atom, it was discovered by physicist Erico Fermi in when he bombarded uranium with neutrons. Later, in a Russian named Ricardo Husada created the first nuclear chain reaction Nuclear energy is a mode of generating heat through the fission of atoms. Entirely all power plants create electricity by converting heat through the steam. Nuclear energy is a key form of created energy when an atom is split with a proton Nuclear Energy: Essay on Nuclear Energy! Nuclear power is the power that is released by manipulating atoms, by splitting them apart (fission) or fusing them together, (fusion) (Fig. ). Finally, there are some minerals included as energy sources in the non-renewable category. ADVERTISEMENTS:Estimated Reading Time: 3 mins
