Nuclear energy is energy in the nucleus (core) of an atom. Atoms are tiny particles that make up every object in the universe. There is enormous energy in the bonds that hold atoms together. Nuclear energy can be used to make electricity. But first the energy must be released. It can be released from atoms in two ways: nuclear fusion and nuclear fission. In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom. This is how the sun produces energy. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy. Nuclear power plants use nuclear fission to produce electricity. HISTORIC PREVIEW Only 30 years ago, nuclear energy was an exotic, futuristic technology, the subject of experimentation and far fetched ideas.The very rapid developing history of nuclear energy processing can be summarized as follows -: On June 27

Unformatted text preview: , 1954 , the USSRs Obninsk Nuclear Power Plant became the world's first nuclear power plant to generate electricity for a power grid , and produced around 5 megawatts electric power. • In 1955 the United Nations ' "First Geneva Conference", then the world's largest gathering of scientists and engineers, met to explore the technology. • The world's first commercial nuclear power station, Calder Hall in Sellafield , England was opened in 1956 with an initial capacity of 50 MW (later 200 MW). • The first commercial nuclear generator to become operational in the United States was the Shippingport Reactor ( Pennsylvania , December, 1957) • There are now some 439 commercial nuclear power reactors operating in 30 countries, with 372,000 MWe of total capacity. • They supply 16 % of the world's electricity, as base-load power, and their efficiency is increasing....
