Nuclear Power
Nuclear fission is a nuclear reaction which the atomic nucleus breaks up into tiny fragments, usually two fragments of the same size, letting off around 100 million to several hundred million volts of energy. This energy is place accordingly to form a really big and violent explosion. The idea of the atom has been around for several centuries, it has also been thought that the ideas were first there from the Greek philosophers. But it has been quite recent when mankind started to learn and understand the massive power placed in this small atomic mass.It was around the time of World War 2 when nuclear scientists focused mainly on a way to create nuclear weapons to be used in the time when size, money and weapons matter to protect their country. They came up with nuclear fission and fusion. After the war, scientists started concentrating on peaceful and more useful ways to use this nuclear technology to help benefit the people and contributed to the advancing society. After years of study and research, scientists have successfully applied the nuclear technology to plenty other scientific, medical, and industrial style purposes. You can see on the map below the main nuclear areas.
Pressurized water reactors uses a separate circuit of cooling water under a high pressure, plus it also has a heat exchanger to make steam for a turbine and generator. The design consists of a gun, containing uranium 235, which fires at another mass of uranium 235. It is used for many purposes, such as;"h It is cheap to make - it costs about the same as coal "h It does not produce greenhouse gases "h It can produce large amounts of electricity "h It is reliable "h Great use in the medical industry, such as treating leukemia, cancer, x-rays and also used to study the blood flowThese are all great and they help human society a great deal but there are also a couple of downsides to this as well;"h Lots of money has to be spent on safety in nuclear power plants because of the tragic consequences if the plant explodes "h The waste from nuclear energy can stay radioactive for thousands of years. Peace should be established between all the countries to save these billions of dollars and tons of nuclear energy and to use it to help contribute to the ever-advancing future. The high explosive substance, which covers the fissile material is lit, causing a shock wave2. The Little Boy design is an example of a nuclear fission reactor. This is the final fission equation for the reactionThe two fragments (Xe-140 and Sr-94) are both very jumpy and unstable, and they undergo beta decay (with the emission of an electron) until each reach a stable end product. This brings up the idea of chain reaction, which can be possible when there are more neutron produced than consumed. Raising and lowering the control rods in the core can speed up or slow down the rate of the chain reactionThere are many different types of fission reactors, although the basics behind them is similar, they all vary to suit the job. Most of the reactors being used these days are either "boiling water" or "pressurized water" reactors, using either normal or heavy water to both cool and moderate the fission reaction. These fragments, are pretty much equal to half of the original mass. It is actually the U-236, which takes part in the fission process, splitting into two fragments.
