NUCLEAR ENERGY

Today, I decided to talk about because nuclear power and its disadvantages as a renewable source of energy. Nuclear power involves the use of heat generated of nuclear chain reactions to produce significant amounts of usable energy, such as electricity. For a period of time, nuclear power was thought to be the solution to the world’s energy increasing demands. That is because initially nuclear power was viewed as a reasonable source of power in terms of economics, environmental issues, and energy output. Later on, the media revealed to the public serious potential danger of nuclear power to the ecosystem of the environment and living organisms. The production of nuclear power usually results with radioactive nuclear wastes or by-products that should be stored and disposed safely. The safe storage and disposal of nuclear waste is considered to be a significant challenge due to the waste’s nature that takes along time to decay and it is a very expensive process to conduct because many human and physical resources are required. The most important waste stream from nuclear power plants is spent fuel. Spent fuel is (a term used among nuclear engineers) is a very radioactive chemical and needs to be handled with great care and given special attention, and that’s due to its lethal nature to its living surroundings. Conversely, spent nuclear fuel becomes less radioactive over long periods of time due to the half life cycle the radioactive fuel goes through. These radioacive wastes are very dangerous to human life existence and to the living environment and its ecosystem.
