Nuclear Energy


Nuclear energy-This is energy that binds together components of an
atomic nucleus. This is made by the process of nuclear fission. Nuclear
fission 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 nucleuses
can 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 are
moving 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 biomes. 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. The
shielded 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
a 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 castrophic 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
