what is nuclear energy
el uranio es el reactivo clave para el correcto funcionamiento de la energía nuclear.
Nuclear energy is the use of nuclear reactors to produce energy transforming radioactive uranium to thorium isotopes that produce massive energy. It is non renewable because uranium gets depleted. It is also very expensive not forgetting the danger of nuclear waste.
What is nuclear fission?
The transformation of radioactive uranium and, in some instances, thorium isotopes provides vastly more energy per unit mass of fuel than any other energy source, except nuclear fusion, and therein lies its greatest attraction. The key to that remarkable fact is the conversion of matter (with mass, m) into energy (E), according to Einstein's famous equation E = mc2 , where c is the speed of light (3×108 m s-1 ).
The potential of nuclear fuels for energy production became a reality when the first experimental atomic pile, built by Enrico Fermi and Léo Szilárd at the University of Chicago, began functioning in December 1942. That led to the manufacture of fissionable material for the first atomic weapons.
The use of nuclear power for electricity production expanded rapidly in the 1960s, a period when the costs of building nuclear power stations and of purchasing the uranium fuel were thought to be less than for fossil fuel plants.
The nuclear industry received a boost in the early 1970s, when fossil fuel prices rose abruptly during the oil crisis of 1974 - following the Yom Kippur war of late 1973, oil producers in the Middle East quadrupled the price of their crude oil almost overnight.
During the 1980s, however, the costs of building nuclear power stations rose inexorably as stringent safety requirements grew, especially following the accident at Three Mile Island in Pennsylvania (1979) and the much larger one at Chernobyl (1986) in the Ukraine.
In addition, the cost of decommissioning nuclear reactors and of developing secure repositories for radioactive waste had not been taken into account in the initial cost-benefit analyses.
These cost considerations have loomed progressively larger as older nuclear power stations approach the end of their useful lives and as the volume of waste grows year by year.
The global rate of expansion of the nuclear industry had slowed almost to a standstill by the early 1990s, and as demand for uranium fuel fell, so did its price. In other words, the fuel got cheaper as the power stations became more expensive.
In the early 21st century, however, with growing concern about global warming the environmental advantage of nuclear power over fossil fuels is becoming increasingly recognised - it produces no greenhouse gases. It also produces no acid rain, unlike coal and to a lesser extent oil.
By 2003 over 400 nuclear reactors were generating electricity globally, producing over 350 GigaWatt (GW). This amounts to about 16% of global electricity generating capacity. An additional 31 nuclear reactors with an additional generating capacity of 25 GW are currently in construction globally. In the UK many reactors are of an early design and only a few of the younger nuclear power stations match the 1 GW capacity of most fossil-fuel stations. Nevertheless, almost 25% of UK electricity generating capacity is nuclear.
