The Advantages and
Disadvantages of Nucler Power
Nuclear is generated by using uranium which is inetal
mined in various part of the world. The first nuclear chain reaction was
produced on December 2, 1942, at the University of Chicago. In 1951, the first
experimental breeder reactor was built near ICI,1110 Falls.
The first large scale of nuclear power station was opened
at Calder Hall in Cumbia, England in 1956. The first large nuclear station in
the United States was completed in 1957, in Shipping port near Flittsburg.
Some military ships and submarines have nuclear power
plants for engine. Nuclear power produces around 11% of the world’s energy
needed, and produces huge amounts of energy. It causes no pollution as we would
get when burning fossil fuels. If nuclear energy is fully developed , it could
supply all the world’s electricity for millions of years.
‘I lie advantages of a twelcar plant are as follows: It
much less i’l,. than docs a fossil fuel plant.
It does not produce smoke and carbon dioxide, so it does
not riot cntribute to the (-,free
It produces liLi (,e an~ounts ofener-v from a srnall
amount of uranium. 11 produce, a stliall, amount of waste.
It is realiable.
On the other hand, a nuclear power is very, very
dangerous. The hot waste water h-orn nuclear is dumped into lakes and treams. This
can harm animals and plants that live at lower temperature. Another problem
involves disposal of fission products, the radioactive wastes produced by
reactors. They must be sealed up and buried for many years to the radioactivity
to die away. Furthermore, although it is reliable, a lot of money has to be
spent on safety, because if it does go wrong, a nuclear accident can be a major
accident. People are increasingly concerned about this matter. In the 199Ws,
nuclear reactor was the fastest growing source of power in many parts of the
world.
