what is nuclear energy
Answers
Answer:
Nuclear power is the use of nuclear reactions that release nuclear energy to generate heat, which most frequently is then used in steam turbines to produce electricity in a nuclear power plant. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium. Nuclear decay processes are used in niche applications such as radioisotope thermoelectric generators. Generating electricity from fusion power remains at the focus of international research. This article mostly deals with nuclear fission power for electricity generation.
Nuclear energy is the energy released during nuclear fission or fusion, especially when used to generate electricity. It is also considered as one of the alternative sources for producting electricity but it is difficult to get rid of nuclear waste. So we don't use nuclear energy on a wide array.
