What are some main causes of Nuclear Power?

Answer 1

Serious nuclear power pollution from a reactor has only happened a few times. In the case of the Chernobyl disaster, in 1986, active material was spread around near the site, and gaseous fission products as well as gases from the burning graphite were carried as a plume for many miles, as there was no control once the fire started. At Windscale in England an early air cooled reactor caught fire,in the 1950's, but most of the radiation was absorbed in filters. At Three Mile Island in Pennsylvania in 1979 a partial fuel meltdown occurred but very little radiation escaped.

Smaller scale pollution has occurred in some places due to fuel processing, Sellafield in the UK for example, where minor leaks have happened in some of the chemical processes. There probably have been such leaks in Soviet Russia which we don't know about. I believe there was some pollution around the Hanford site in Washington state, that was part of the WW2 effort and in those days the risks were less well known than today, and I expect corners were cut in order to achieve the required programme. Provided enough time and effort and money is put in to the nuclear programme, there is really no need for such leaks to occur, its a matter of good housekeeping, and thinking in advance what the risks might be.

Answer 2

Nuclear fission is caused due to the nuclear reaction of two heavy nucleus of Uranium-235 and Uranium-238 which results to split spontaneously or impacts with another each other, with the release of large amount of energy.

Answer 3

The biggest cause of nuclear power is the fusion of lighter atoms into heavier elements in the hearts of stars. Using our sun as an example the heat and light generated from this reaction some 93 million miles away keeps out planet at a cosy (for us) temperature. By comparison nuclear power created by all the worlds reactors and nuclear bombs is very samll/
