Nuclear Power Plants example essay topic

Nuclear Energy Nuclear energy-This is energy that binds together components of anatomic nucleus. This is made by the process of nuclear fission. Nuclearfission is produced when an atomic atom is split. The way nuclear pore is made is in a nuclear reactor, this is most likely located in a nuclear power plant. the fission that is produced is when a heavy element splits in half or is halved into two smaller nuclei, the power of the fission is located by the rate of the splitting of the nuclei at once which causes watts of electricity to be forced into the energy type. Energy that is released by the nuclear fission matches almost completely to that of the properties of kinetic fission particles, only that the properties of the nuclear energies nucleus are radioactive. These radioactive be contained and used as fuel for the power.

Most of this power is fueled by uranium isotopes. These isotopes are highly radioactive. The isotope catches the fast moving neutrons created by the splitting atoms, it repels the slower moving protons and electrons, then gathers the neutrons and pulls them inward. While all these atoms are flying about they smash together then split many of many times, this is when the reactor grabs and pulls in the frictional energy to be processed into electrical watts.

This usually causes heat or thermal energy, this must be removed by some kind of a coolant. Most power plants use water or another type of liquid based formula. these coolants are always base related, never acidic. Very few use gas related coolants in there reactors, these are known as thermal reactor based power plants. Another nuclear reactor type is a type that runs off of uranium oxide, the uranium oxide is a gas form of the solid uranium. These fuels which cause the radioactive particles usually are always highly radioactive themselves. Because of this all the power plants take high safety standards and use special shields to prevent leakage.

Usually the leakage can cause nuclear contamination. This means they must take high safety standards. After nuclear fission has occurred many of the thermal neutrons a removing at thermal neutrons are moving at thermal velocities which are harder to be absorbed, so they rely on constructional details. Usually they use thick medals such as lead or tungsten, usually now though the barrier is made of concrete. The average shield of a power plant twelve to fourteen feet in diameter and fifteen to twenty feet high.

This creates a problem with gamma ray leakage out into the biome's. this usually would only happen in a time of crises, this is why shields are so highly needed. Because of this factor there are secondary shields only used in cases of extreme emergencies. Usually this action triggers the fast pace emergency reactions. In this time the secondary emergency system reacts, the way that it reacts is by enclosing the reactor in a gastight chamber. This chamber has airlocks, these airlocks are double sealed and are usually two sided.

Theshielded covers the entire reactor, and the primary coolant system. All the coolant vents are automatically shut up and off. This safely contain the fission products inside the shell. Another way of stopping this is the Negative Temperature Coefficient, what this seal does is seal off the reactor and pump in gases that are of sub-zero negative temperature properties, this freezes the thermal neutrons, slow the fission, and finally freeze the radiation particles.

These procedures are highly effective in stopping the contamination of the local community. Because of all the possible damage nuclear power plants are designed and operated in a manner that emphasizes the prevention of accidental release of radioactivity out into the environment. there has never been a death caused by commercial nuclear power plant that are located in the United States of America. The potential for cancer and genetic damage as the result of the accidental release of radioactivity has led to an increased public concern about the safe operation of reactors. Although the direct health effects from the resulting release of radioactivity into the environment are still being investigated, the psychological effects of an accident could damage the nuclear power associations credibility. International concern over the issue of reactor safety was renewed following an accident at a facility in the Soviet Union in April 1986.

The Chernobyl nuclear power plant, which is located 80 miles northwest of Kiev in Ukraine suffered a ca strophic meltdown of its nuclear fuel. A radioactive cloud spread from the plant over most of Europe, this contaminated a very large amount of crops, and livestock. Lesser amounts of this radiation showed up. These are some reasons why people and the community are very cautious against nuclear power, I hope that this report can better inform people on this issue, even though nuclear energy is the cleanest, and supposedly the safest Istill lay undecided. Here are some pictures on the topic. Nuclear energy-This is energy that binds together components of anatomic nucleus.

The way nuclear pore is made is in a nuclear reactor, this is most likely located in a nuclear power plant. the fission that is produced is when a heavy element splits in half or is halved into two smaller nuclei, the power of the fission is located by the rate.
