- Nuclear power is the controlled use of nuclear reactions to release energy for work including propulsion, heat, and the generation of electricity. Human use of nuclear power to do significant useful work is currently limited to nuclear fission and radioactive decay. Nuclear energy is produced when a fissile material, such as uranium-235 (235U), is concentrated such that nuclear fission takes place in a controlled chain reaction and creates heat — which is used to boil water, produce steam, and drive a steam turbine. The turbine can be used for mechanical work and also to generate electricity. Nuclear power is used to power most military submarines and aircraft carriers and provides 7% of the world's energy and 17% of the world's electricity. The United States produces the most nuclear energy, with nuclear power providing 20% of the electricity it consumes, while France produces the highest percent of its energy from nuclear reactors—80% as of 2006. [1] [2] International research is ongoing into various safety improvements, the use of nuclear fusion and additional uses such as the generation of hydrogen (in support of hydrogen economy schemes), for desalinating sea water, and for use in district heating systems. Construction of nuclear power plants declined following the 1979 Three Mile Island accident and the 1986 disaster at Chernobyl. Lately, there has been renewed interest in nuclear energy from national governments, the public, and some notable environmentalists due to increased oil prices, new passively safe designs of plants, and the low emission rate of greenhouse gas which some governments need to meet the standards of the Kyoto Protocol. A few reactors are under construction, and several new types of reactors are planned. The use of nuclear power is controversial because of the problem of storing radioactive waste for indefinite periods, the potential for possibly severe radioactive contamination by accident or sabotage, and the possibility that its use in some countries could lead to the proliferation of nuclear weapons. Proponents believe that these risks are small and can be further reduced by the technology in the new reactors. They further claim that the safety record is already good when compared to other fossil-fuel plants, that it releases much less radioactive waste than coal power, and that nuclear power is a sustainable energy source. Critics, including most major environmental groups believe nuclear power is an uneconomic, unsound and potentially dangerous energy source, especially compared to renewable energy, and dispute whether the costs and risks can be reduced through new technology. There is concern in some countries over North Korea and Iran operating research reactors and fuel enrichment plants, since those countries refuse adequate IAEA oversight and are believed to be trying to develop nuclear weapons.

Presently, the nuclear fission of elements in the actinide series of the periodic table produce the vast majority of nuclear energy in the direct service of humankind, with nuclear decay processes, primarily in the form of geothermal energy, and radioisotope thermoelectric generators, in niche uses making up the rest. Nuclear (fission) power stations, excluding the contribution from naval nuclear fission reactors, provided 13% of the world's electricity in 2012. The share of the world's primary energy supply, which refers to the heat production without the conversion efficiency of about 33 %, was about 5.7%. Its share of the global final energy consumption (actually useful energy, i.e. electric power) is below 2.5 %. In 2013, the IAEA report that there are 437 operational nuclear power reactors, in 31 countries, although not every reactor is producing electricity. In addition, there are approximately 140 naval vessels using nuclear propulsion in operation, powered by some 180 reactors. As of 2013, attaining a net energy gain from sustained nuclear fusion reactions, excluding natural fusion power sources such as the Sun, remains an ongoing area of international physics and engineering research. More than 60 years after the first attempts, commercial fusion power production remains unlikely before 2050. There is an ongoing debate about nuclear power. Proponents, such as the World Nuclear Association, the IAEA and Environmentalists for Nuclear Energy contend that nuclear power is a safe, sustainable energy source that reduces carbon emissions. Opponents, such as Greenpeace International and NIRS, contend that nuclear power poses many threats to people and the environment. Nuclear power plant accidents include the Chernobyl disaster (1986), Fukushima Daiichi nuclear disaster (2011), and the Three Mile Island accident (1979). There have also been some nuclear submarine accidents. In terms of lives lost per unit of energy generated, analysis has determined that nuclear power has caused less fatalities per unit of energy generated than the other major sources of energy generation. Energy production from coal, petroleum, natural gas and hydropower has caused a greater number of fatalities per unit of energy generated due to air pollution and energy accident effects. However, the economic costs of nuclear power accidents is high, and meltdowns can render areas uninhabitable for very long periods. The human costs of evacuations of affected populations and lost livelihoods is also significant. Along with other sustainable energy sources, nuclear power is a low carbon power generation method of producing electricity, with an analysis of the literature on its total life cycle emission intensity finding that it is similar to other renewable sources in a comparison of greenhouse gas(GHG) emissions per unit of energy generated. With this translating into, from the beginning of nuclear power station commercialization in the 1970s, having prevented the emission of approximately 64 gigatonnes of carbon dioxide equivalent(GtCO2 -eq) greenhouse gases, gases that would have otherwise resulted from the burning of fossil fuels in thermal power stations. As of 2012, according to the IAEA, worldwide there were 68 civil nuclear power reactors under construction in 15 countries, approximately 28 of which in the Peoples Republic of China (PRC), with the most recent nuclear power reactor, as of May 2013, to be connected to the electrical grid, occurring on February 17, 2013 in Hongyanhe Nuclear Power Plant in the PRC. In the USA, two new Generation III reactors are under construction at Vogtle. U.S. nuclear industry officials expect five new reactors to enter service by 2020, all at existing plants. In 2013, four aging, uncompetitive, reactors were permanently closed. Japan's 2011 Fukushima Daiichi nuclear disaster, which occurred in a reactor design from the 1960s, prompted a re-examination of nuclear safety and nuclear energy policy in many countries. Germany decided to close all its reactors by 2022, and Italy has banned nuclear power. Following Fukushima, in 2011 the International Energy Agency halved its estimate of additional nuclear generating capacity to be built by 2035.

Later on, at the closing ceremony, Nikki Webster was powered by nuclear power, which led to her being taken away for scientific research for the Ebola virus. Then in 1942, Enrico Fermi, being an immigrant, was ordered by the government to "get a job or get your dago wop ass back to Sicily or wherever you greaseball goombas come from" (FDR's words). He got a job as janitor at the University of Chicago, mopping up puke and suchlike. One day, while chasing rats for lunch in the basement of the Physics Building, he accidentally pushed some graphite and uranium rods up his ass, thus creating the first atomic piles. The rest of the nuclear technology subsequently developed at the U of C he sold to Russia for a bottle of cheap chianti and a pair of brass knuckles for his cousin Vito. But later developments ensued. The Advent of a new form of nuclear power, derived from Pwnage, was developed by Dr. Pwnavitz. Thus the term Nuclear Pwnage emurged, as a new factor of pwning pee-ons around the world. The first Nuclear Pwnage Plant, Pwntendo Unit 1, was completed in 1983, during the beginning of the BBS era. It was powered by the pwnage on BBS sites, as well as primitive online gaming, or more like serial linked game systems. It didn't put out too much Pwnage, just about 13 mega pwns an hour (MPH). This led to bigger and better pwnage systems to come.
- Assignment: Create a page that illustrates the following aspect of nuclear power production. Use other sources as much as possible and acknowledge them properly. Note that these questions are rooted in topic 6 in the syllabus, but are developed in topic 8 which discusses energy production. The Role of the Chain Reaction in Nuclear Power Production (1) In nuclear power production, a neutron is fired at an atom, causing fission and in the case of Uranium-235, the release of two more neutrons. This causes the process to repeat itself all over again; each neutron triggers another atom's nuclear fission and produces two neutrons for another two nucleuses. Therefore the rate of fission rises exponentially in nuclear reactors. 235U92 + 1n0 --> fission products + (2.5)1n0 + 200 MeV Energy This equation defines how U-235 reacts with neutrons and splits. However, while nuclear fission produces several neutrons, not all of these neutrons can go on to cause fission elsewhere; only low-energy neutrons can cause fission. Low energy refers to about 1 eV. Therefore it follows that if useable neutrons are not produced faster than fission takes place, the chain reaction will eventually die out and end. (3) "The smallest mass of fossile material that will support a self-sustaining chain reaction under specified conditions" (2), or the smallest amount of material that won't die out and end, is known as the Critical Mass. The figure for critical mass can change. Depending on the shape of the material, what the material is made of and how dense it is, and whether or not it is contained within a "neutron reflector," the amount of material necessary for a sustainable chain reaction can be changed.
