Nuclear fission is going to become more and more useful in worldwide power production for the foreseeable future. The reasons are numerous, but can be summarized by the relative ease of reliable power production that is provided. This does not go without having many disadvantages. But it is the fact that nuclear fission provides a massive amount of reliable electrical energy at a relatively low cost that has many countries investigating the possibilities of nuclear power generation. To understand why nuclear power would be the only option (at this time) for an alternative to fossil fuel burning for energy production is to understand its history, the world’s current power production from nuclear power, and where it is going in the foreseeable future. The first man-made nuclear reactor, Chicago Pile 1, achieved critical status on December 2, 1942 (Department of Energy 1982). This crude reactor resembled more of a wood and brick lattice work than what many think of a nuclear reactor. This reactor was built under the supervision of both Enrico Fermi (who, along with J. Robert Oppenheimer, are known as the “fathers of the atomic bomb”) and Leo Szilard (first to conceive the idea of a nuclear chain reaction). It is Szilard that is responsible for the formation of the Manhattan Project (Department of Energy 2006). More importantly for power production, the reactor was made of a series of piles of uranium and graphite bricks, with wood planks providing both support and structural references. The control mechanisms were made of cadmium coated rods that easily absorbed the free-flowing neutrons of the controlled chain reaction. This first reaction produced only ½ of a watt of energy, but within ten days, the production was at 20... ... middle of paper ... ...: Characterization, treatment, and environmental impacts.

Non-renewable resources such as fossil fuels have been used up by society on a daily basis and have forced the world to find a new, clean energy source. The rising price of oil and the constant emission of carbon dioxide are proof that in the future our lives will be much harder to live. One answer to this problem is nuclear power, which has shown its efficiency during the times of World War II but has not been used commercially due to the challenges of dealing with nuclear waste and proliferation. In today?s modern era, nuclear power has been used in liquid metal fast breeder reactors, reactors that use uranium-238 to produce plutonium-239.
The world's natural resources are being consumed at an alarming rate. As these resources diminish, people will be seeking alternative sources by which to generate electricity for heat and light. The only practical short-term solution for the energy/pollution crisis should be nuclear power because it is available, cleaner and safer.
The world is facing an energy crisis and many are unaware of this growing problem. Sustainability is avoiding depletion of our natural resources in order to provide for future generations, and the only way to ensure that resources are available into the future is to find alternative sources to meet the world’s energy needs. Nuclear energy is just one source of alternative energy being implemented today in an effort to support the needs of the population and mitigate global climate change. Nuclear energy holds the necessary benefits in order to continue being used globally as an alternative solution.
Our world today is growing every day every year and there will be a time where more and more energy will be needed to sustain human life. The demand for electricity and its value is increasing rapidly and will only continue to do so. The world will need greatly increased energy supply in the next 20 years, especially clean generated electricity [WNA, 2014]. Fourteen percent of the world’s electricity comes from nuclear energy to use. The use and demand for electricity will increase in 2030 by eighty one percent. Therefore, nuclear power plants need to rise to fulfill the demands and needs for the growth of the population. Since the demand for electricity is increasing and with many resources to get electricity from, the use of nuclear energy without constant support will probably decline to around 9 percent or less by 2035. At least two factors will make this quite difficult for nuclear energy to gain a bigger m...

Compare and Contrast Nuclear Energy and Alternative Energy. Standard Number Science 3.4. Today, our society is using more energy than ever. With the increase in demand for energy, problems are presented that have to be addressed.
Nuclear energy is a tricky topic. At first thought, the word nuclear tends to throw some for a loop, flashing images of deadly “nukes” and atom bombs in their heads. However, nuclear energy can offer a wide array of benefits that can realistically solve the growing energy crisis our planet will soon face, not to mention the many rewards that nuclear research can lead to. As fossil fuels slowly get burned away, where will we turn to next? Yes, there are several renewable sources of energy that can help, but none that are a clean everyday-everywhere solution. Unfortunately, nuclear power is not without its own issues, as no source of energy is perfect. Nuclear energy can be wildly beneficial, both as an energy source and research port, but at what cost?
Nuclear power has grown to be a big percentage of the world’s energy. As of January 18, 2013 in 31 countries 437 nuclear power plant units with an installed electric net capacity of about 372 GW are in operation and 68 plants with an installed capacity of 65 GW are in 15 countries under construction. As of end 2011 the total electricity production since 1951 amounts to 69,760 billion kWh. The cumulative operating experience amounted to 15, 15,080 years by end of 2012. (European Nuclear Society) The change that nuclear power has brought to the world has led to benefits in today’s energy’s usage.
Around 1894, scientists discovered that by bombarding a radioactive substance with neutrons, a highly powerful energy could be produced. This is ionizing radiation, which is strong enough to rip the electrons from the nucleus of an atom, hence the name “nuclear energy.” over a century later, nuclear substances are harnessed in order to provide energy. However, nuclear energy is not only discussed amongst scientists, but anyone fearing the safety and future of the environments surrounding the area where a nuclear power plant is implemented.
Nuclear power may lead to some extensive breakthroughs in multiple fields for better or for worse in the case of humanity and its survival. It’s a topic that people need to take a bit more seriously as it holds the chance to make or break the future for earth and its inhabitants. Greater risks have greater rewards and as observance of nuclear products and ideas deepen then so do the products yield, perhaps into infinity. While nuclear power is accompanied by several risks, it can also be the solution for various global strains and difficulties. Sufficient energy for the world is a huge goal to tackle and requires the use of any efficient resource we have, especially when the source has so much potential.
Nuclear fission may sound like a radically scientific process, but in reality it is actually very simple and logical. Nuclear power plants use Uranium, a naturally occurring element, as fuel. Basically, the uranium is converted into Uranium dioxide through chemical means and is compressed into a pellet. The pellets are placed into tubes and then into the reaction core where the process takes place. Uranium is a radioactive element, which means that in its natural form, it is unstable and regularly releases subatomic particles. When it is in the reactor, free neutrons are released and collide with the Uranium which causes it to release its own neutrons causing a chain reaction. All of this is happening very quickly and doing so it releases enormous amounts of heat. This heat is then used boil water into steam, turning turbines and producing electricity. There are also rods that are placed between the fuel rods that will absorb some of the neutrons. This is to control the amount of reactivity and heat being produced (Schrock 3). After the reaction is complete, t...

“Every dollar spent on nuclear energy is one less dollar spent on clean renewable energy and one more dollar spent on making the world a comparatively dirtier and a more dangerous place, because nuclear power and nuclear weapons go hand in hand” (Jacobson). Most countries today are becoming more and more dependent on nuclear power as a source of energy because of its high energy output and the availability of uranium used for fuelling nuclear reactors that generate power to provide electricity in households. Although using nuclear power as a source of energy has benefits like this, the danger posed by using nuclear power is too ominous.
Nuclear energy, also known as atomic energy, became popular in the early 20th century. The atom held enormous capacity of energy - the uranium (uranium-238 and uranium-235) is formed into solid ceramic pellets packaged into long, vertical tubes for uses. In the reaction, the pellets are bombarded with neutrons, which causing the uranium atoms to split and release heat and neutrons, then the neutrons collide with other uranium atoms and release additional heat ...
However, nuclear power is a sustainable energy source which reduces carbon emissions, produces virtually no air pollution, and increases energy security. Because of western world energy codes and technologies, the methods of storing/disposing of nuclear waste are safer than ever. In addition to an increased focus on saving the environment, many governments have proclaimed a need for energy through a method that is environmentally friendly. According to the World Nuclear Association, “Electricity demand is increasing twice as fast as overall energy use and is likely to rise by more than two-thirds 2011 to 2035 (World Energy Needs and Nuclear Power)”. As of now, Nuclear power provides about 11% of the world's electricity (Ricotti). Only through nuclear energy will the world’s exponential energy demands be met. Despite political hype, environmental consequences, and lack of facility standardization, Nuclear power continues to offer a solution to be a worldwide, emission-free, scalable energy source that can meet global energy demands, as...
