No new orders for nuclear power plants have been placed in the US since the mid 1970s. Nuclear electricity generation became unpopular in the United States after the accident at Three Mile Island in 1979. Coal provides about 55% of the country's electricity, natural gas (9%), oil (6%), and hydropower (9%). nuclear energy program is the world's largest with 108 operating plants with 100, 000 MW capacity, providing some 20% of the country's electricity in 1989. 130 more were in design or construction stages. This is usually done in a Boiling Water Reactor ( BWR) or a Pressurized Water Reactor ( PWR), but there are other options such as the fast breeder reactor.Īt the end of 1989 there were 416 nuclear fission power plants operating worldwide, producing about 17% of the worlds electricity. The heat from the nuclear fission is used to: Nuclear fusion: the combining of light nuclei.Ĭurrent uses of nuclear energy must rely on nuclear fission, a less-than-ideal energy source, since nuclear fusion has yet to be harnessed for electricity generation. A fractionof the mass can be converted to energy by: Nuclear fission: the breaking up of heavy nuclei. However, direct mass conversion is not possible on a large scale. citizen per year(used as a reference unit ) would require: To supply the yearly average of 5 x 10 11 joules per U.S. * This amount will be used as a comparison unit when discussingĮnergy production by nuclear fission and nuclear fusion. citizens for one year, or the needs of a city of one million for over two months. So one kilogram of mass conversion could supply the needs of about 180,000 U.S. citizen for one year is about 1 US year* = 5 x 10 11 Joules Nuclear fission and nuclear fusion are different types of reactions that release energy (when exothermic) due to the formation of nuclei with higher nuclear binding energy. The yield from converting one kilogram is E=(1 kg)(3 x 10 8) 2= 9 x 10 16 joules Mass can be converted into energy with a yield governed by the Einstein relationship: E=mc 2 Our product offerings include millions of PowerPoint templates, diagrams, animated 3D characters and more.Energy from Nuclear Processes Energy a la Einstein is brought to you by CrystalGraphics, the award-winning developer and market-leading publisher of rich-media enhancement products for presentations. Einstein’s equation explains the mass-to-energy conversion: E mc 2. It converts hydrogen atoms into helium (or, in other words, creates helium nuclei from protons), and it transforms mass into energy. Then you can share it with your target audience as well as ’s millions of monthly visitors. Nuclear fusion is the source of all the energy emitted by the Sun, does two things: 1. We’ll convert it to an HTML5 slideshow that includes all the media types you’ve already added: audio, video, music, pictures, animations and transition effects. You might even have a presentation you’d like to share with others. And, best of all, it is completely free and easy to use. Whatever your area of interest, here you’ll be able to find and view presentations you’ll love and possibly download.
