Nuclear Energy
U-235 is one of the few substances whose atoms can be split to obtain energy (7), also known as fission. Uranium 235 is the main important fuel in producing nuclear energy and this report is all about nuclear energy.
Nuclear energy all starts when a neutron, part of the nucleus
of an atom, hits the nucleus of a Uranium-235 atom, which contains 235
neutrons and protons (7). The nucleus of the atom is split (fission)
and some extra neutrons are released. 
Fission
also produces a lot of heat energy. The heat energy boils water that
transforms to high- pressure steam. The high-pressure steam turns a
turbine that then spins a generator. A generator has magnets facing
a certain way that spin inside of coil sixty times a second, or a generator
could also be coil spinning inside a force of magnets. After the electricity
is made, the hot water goes through the cooling tower or towers. Then
after that the cooling 
towers
cool down most of the water and it can be put back in a lake and it
won’t be burning hot for the animals that live in the water.
Some nuclear shortcomings are that waste happens at all times during the nuclear fuel cycle. (3). Radiation in the waste can stay for thousands of year. If people are exposed to any radiation they can get sick and die. A nuclear reactor cost more then a fossil fuel plant because of all the dangers. Nuclear plants can also blow up, so they are built in an isolated place.
One advantage of nuclear energy is that, after it is built, a nuclear power plant cost less than a fossil fuel plant because it doesn’t use as much fuel as the fossil fuel plant does. Uranium 235 can be used over and over again (6).
There is an infamous nuclear reactor in Chernobyl,
Russia. The Chernobyl reactor blew up one time some years
ago. This is probably the biggest disadvantage of nuclear power.
They scare people because they can be dangerous. There are
many nuclear reactors everywhere in the world and they produce
a lot of electricity. One example is the reactor near Houston that is called the South Texas
Project. The South Texas Project is one out of a lot of nuclear reactors in the United
States. Seventeen percent of the world’s electricity comes from nuclear energy and the
Unites States of America uses approximately a seven point nine percent average of
nuclear energy by itself (10 & 8). The world has over four hundred nuclear reactors and
the United States of America has over one hundred (8).
Nuclear power plants use very little fuel and the nuclear fuel is the one of a kind fuel
that can depart from itself, but since nuclear energy is dangerous, it is likely to go down in
its
percent average. N

power plants have to be built away from
people because nobody wants one near them
and if nuclear reactor blows up people will not be
able to live on that land for thousands of years.
Nuclear energy is one of the scariest source of
energy to use, but it may be used more in the
future because it is usually safe and pretty
clean.
