This will not only hasten the depletion of uranium stockpiles but also cause the price of uranium to rise possibly making the power it can generate not economically feasible. The second drawback is the amount of nuclear waste uranium produces. Currently, 3% of spent uranium fuel is unable to be recycled (WNA, 2013). The Nuclear Energy Institute estimates that an average nuclear power plant produces 20 tons of this high-level waste each year. The only current method of disposal is to store the high-level waste until it naturally becomes nonradioactive, which can take up to a thousand years.
Since power plants are so expensive many poor countries will not have the opportunity to have nuclear energy (Burgess, J. n.d. para.12). Some argue that that the construction costs will exceed the countries credit limit, making them into deeper debt. Overall in the end Nuclear power plants can be seen as a good alternative for energy and also be seen as harmful. Through fission the power plants are able to create electricity through the two types of nuclear reactors, the Pressurized Water Reactor (PWRs) and the Boiling Water Reactor (BWRs). Most states have nuclear power plants now and produce 20% of the nation’s power; around 3 million Americans live within 10 miles of an operating nuclear power plant (Nuclear power plants, n.d.para.1).
A Weapon converted to Provide Energy Nearly 75 years ago, man split the atom and ushered in an entirely new future for humans. Globally, nuclear power has had a positive and negative impact on society. As the demand for electricity increased during the 20th century into the 21st century nuclear energy provided a cleaner and cheaper resource as well as resulting in a positive impact on society by reducing dependence on fossil fuels and reducing air pollution related deaths. As the demand for global energy rises, nuclear energy is the world 's largest source of emission-free energy and has more energy than any other fuels on earth in a weight to energy produced ratio. Nuclear power plants are capable of providing larger amount of energy in a minimum amount of space.
ABSTRACT The demand of energy is growing, causing the energy crisis to worsen. A new source of energy must be found before fossil fuels run out. Nuclear fusion is a possible way of producing electricity. The D-T and D-3He reactions can produce enough energy to last thousands of years because there is a virtually limitless amount of deuterium on Earth, and tritium and helium-3 can be made from deuterium. Therefore, nuclear fusion is a promising environment-friendly source of energy.
There were 65 nuclear power plants with 104 operating nuclear reactors that generated a total of 769 billion kilowatt-hours (kWh), or 19% of the nation's electricity”(EIA). For example, nuclear fusion is necessary to star composition as the energy emitted from combining two smaller nuclei in the star to form a large nucleus keeps the stars gravity from collapsing in on itself, showing the power of fusing atoms. Therefore a greater number of nuclear plants need to be opened in the United States as well as there being more research put towards nuclear physics. With this said, petroleum is still highly used. Still, while the advantages of nuclear energy are vast.
Presently, the planet contains twenty-five times more nuclear fuel compared to fossil fuel. On average, an atomic power plant can produce half a million kilowatts of power. As a comparison, a hair dryer takes about one kilowatt (Jenny, 1-2). The producing of energy from nuclear fission is very similar to using a very common fossil fuel boiler. The difference lies in the reactor, where the heat is generated by fissioning material.
The fact is that Uranium mining is not yet a safe, economic, reputable industry for Australia and its people. Due to heavily burn of facial material such coal, global warming drawn increasing attention of the world today. As the major source of nuclear power planet, some one believes that the exploration of uranium can be part of the solution to cool down the world temperature. According to Areva (SBS, links), nuclear power can contribute 25% electricity in the next few decades. Therefore, uranium mining industry gains incredibly success to provide key material to nuclear power reactor.
The Threat of Global Warming Through the eyes of most scientists, global warming is seen as a very serious and severe threat. The actions taken by humans, such as industry and consumption of fossil fuels plus the increase in population and agriculture have played a big part in global warming. If something is not done soon the results could be very bad. By the middle of the twenty first century, there is evidence that the Earth will be warmer than it has been at any time in human history, and quite possibly since the end of the dinosaurs, some 65 billion years ago. If we stay at the rate we are now (fossil fuel consumption / growth in population) then within the next two century the Earth's air might not be fit to breath.
The NRC Chairman Dale Klein said that “Nuclear power plants are inherently robust structures that our studies show provide adequate protect... ... middle of paper ... ...e form burning oil, coal and other fossil fuels. Cavanagh said that “Nuclear power is dying a slow death in the market place, which is what matters in determining its future. Scientist in “Pandora’s Promise” claim that globally consumption could double by 2015. They said that the planet is heating up and the ocean is rising, and if the ice sheets start to disintegrate, then is unstoppable. They said that the best thing to avoid that is nuclear power.
Nuclear power should be the next main source of energy because it provides substantially more power than other sources, it is extremely safe, and future advances will provide even greater capabilities. Nuclear power comes from a process called fission. According to one source, fission employs Uranium-235, the highly unstable isotope of Uranium. Uranium-238, the most common state of uranium, cannot produce energy as of right now. First, the nucleus of an atom breaks, releasing its neutrons.
