As begins every typical paper written on the progress of commercial nuclear power, a bit of history related to the nuclear power industry is custom. Beginning with the Generation I reactors (early prototype reactors), such as Shippingport, Fermi I and Magnox, which lead us to Generation II reactors (commercial power reactors), such as the more commonly known light water reactors; pressurized water reactors (PWR) and boiling water reactors (BWR). Other General II reactors include the CANada Deuterium Uranium reactor (CANDU), advanced gas-cooled reactor (AGR), and the voda voda energo reactor (VVER). Next are the Generation III reactors, which consist of the advanced boiling water reactors (ABWR), System 80+, AP600 and European pressurized reactor (EPR). Advancing further brings us to the Generation IV reactors, which are divided into two categories: thermal reactors and fast reactors. A few thermal reactors include the very-high-temperature reactor (VHTR), molten-salt reactor (MSR) and supercritical water reactor (SCWR). Some fast reactors are the Gas-cooled fast reactor (GFR), sodium-cooled fast reactor (SFR) and lead-cooled fast reactor (LFR). Scientists and engineers are constantly working to progress the methods of producing power to improve the safety, efficiency and economics aspects. As studies progress, we inch closer and closer to the ideal commercial plant to wean towards reliable carbon-free power sources. However, despite valiant efforts, society still relies on the generation II PWRs and BWRs as our primary source of nuclear power. Mention figure. In 1958, Savelli M. Feinburg purposed the first known proposal for a fast reactor that could sustain a breed-and-burn condition using only natural or depleted uranium as fue... ... middle of paper ... ...new generation of smaller reactors []. Ideally, TerraPower expects to have the TWR prototype constructed in 2022. The TWR-P is expected to be a 600 megawatt-electric demonstration reactor. The TWR-P is expected to accomplish multiple goals, such as, demonstration the first electricity-producing TWR, confirm the traveling wave design, demonstrate key plant equipment, serve as the last step in our fuels and materials qualification program, and provide the technical, licensing and economic basis for future generations fo TWRs. Thorium If tactics stay on track, the TWR appears as a safe, small-scale nuclear reactor that cuts the cost of power, burns existing nuclear waste as fuel and avoid carbon dioxide and other emissions. TerraPower estimates 700,000 metric tons of spent fuel in the United States alone, and 8 metric tons could power 2.5 million homes for a year.

    About 31 or more people had died from the tragic event in 1986 in Chernobyl, Russia from the accident itself or from thyroid cancer that developed after the incident later on down the road chernobyl was a horrific event and lead to more deaths even after the fact.Another nuclear related accident was when the TMI power planted almost melted down,it showed us that a lot can happen from one small problem such as a faulty pressure valve can over heat the reactor and this could cause a plant to meltdown.A problem we face everyday still is nuclear waste, we wonder where we can put it that allows the population to still be safe.The U.S. is doing a latter approach for nuclear waste and the location chosen for this is Yucca Mountain in Nevada. They feel waste is to dangerous to just leave it.A good thing about power plants is that they are safer than other methods in the working field.Nuclear power is useful but with the radiation given off or if the power plant exploded or something along those lines the radiation is stronger and more powerful and can spread across a location and kill many. Nuclear power is also safer having less deaths on the job compared to other generating sources known as oil refiners or other fossil fuel jobs.

  • Nuclear Waste Essay

    1237 Words  | 3 Pages

    Since the dawn of civilization, all living (and some non-living) things have needed energy. When humans discovered fire, the first form of harnessed energy, it made it easier to stay warm, prepare food, make weapons, etc. Since then, humankind has been inventing new ways to harness energy and use it to our advantage. Now-a-days, people in most nations depend extremely heavily on fossil fuels – to work, travel, regulate temperature of homes, produce food, clothing, and furniture, as well as other power industries. Not only are these fossil fuels dominating our society and creating economic vulnerability, but they also produce waste that causes a number of social and environmental concerns. The waste from these fuels leads to acid rain, smog, and climate change. It also releases sulfur dioxide as well as other air pollutants that are very harmful to the human respiratory system (Morris, 1999, p. ix). There are other alternative sustainable energy sources including solar, hydroelectric, wind, and biomass. However, the main source aside from fossil fuel is nuclear energy from controlled nuclear reactions (where nuclei of radioisotopes become stable or nonradioactive by undergoing changes) in a nuclear power plant. Nuclear power produces enormous amounts of energy to serve a community. Unfortunately, nuclear energy has its own set of problems – a big one being its waste. The spent fuel from nuclear plants is radioactive. This means that it emits radiation, or penetrating rays and particles emitted by a radioactive source. Ionizing radiation is known to cause cancer, and therefore makes anyone who lives near spent nuclear waste facilities vulnerable to this incurable disease. The disposal of nuclear waste is a global issue...

    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...

    Media coverage of such cases have made the public less comfortable with the idea of moving further towards nuclear power and they only opt for reducing human activities to reduce global warming. It is true that there have been some notable disasters involving nuclear power, but compared to other power systems, nuclear power has an impressive track record. First, it is less harmful and second, it will be able to cater for the growing world population. Nuclear power produces clean energy and it delivers it at a cost that is competitive in the energy market (Patterson). According to the US Energy Information Administration, there are currently 65 such plants in the Unite States (National Research Council). They produce 19 percent of the total US energy generation.

    Nuclear power has always been a controversial issue because of its inherent danger and the amount of waste that the plants produce. Once considered a relatively safe form for generating energy, nuclear power has caused more problems than it has solved. While it has reduced the amount of traditional natural resources (fossil fuels), used to generate power like coal, wood, and oil, nuclear generating plants have become anachronisms. Maintaining them and keeping them safe has become a problem of immense proportion. As the plants age and other technology becomes available, what to do with these “eyesores” is a consuming issue for many government agencies and environmental groups. No one knows what to do about the problem and in many areas of the world, another nuclear meltdown is an accident waiting to happen. Despite a vast array of safety measures, a break in reactor pipe or a leak in a containment vessel, could spell another environmental disaster for the world.

    The use of nuclear energy has increased in the United States since 1973. Nuclear energy's share of U.S. electricity generation has grown from 4 percent in 1973 to 19 percent in 1998. This is excellent news for the environment. Nuclear energy and hydropower are the cleanest large-scale means of electricity production. Since nuclear power plants do not burn fuel, they emit no combustion byproducts—like carbon dioxide—into the atmosphere (www.nei.org). Nuclear power can come from the fission of Uranium, plutonium or thorium or the fusion of hydrogen into helium. Today uranium (U-235 and U-238) is most commonly used in the production of nuclear energy. The expa...

    Because light water reactors manage dangerously high pressures, large containment buildings have to be built. Liquid fluoride thorium reactors have no high pressure and are safer, so less money is spent on construction and safety systems. The fuel cost is lower as well because thorium is four times more common than uranium. Developing liquid fluoride thorium reactors and factories to meet our energy needs would cost around $5 billion. The total to build a 100-megawatt liquid fluoride thorium reactor on an assembly line would total about $200 million, and the fuel costs about $10,000 per year. In comparison, it costs $10-12 billion to make one new light water reactor and $50-60 million for fuel every

  • Nuclear Power: Dirty, Dangerous and Expensive

    3279 Words  | 7 Pages

    The energy industry is beginning to change. In today’s modern world, governments across the globe are shifting their focuses from traditional sources of power, like the burning coal and oil, to the more complex and scientific nuclear power supply. This relatively new system uses powerful fuel sources and produces little to no emissions while outputting enough energy to fulfill the world’s power needs (Community Science, n.d.). But while nuclear power seems to be a perfect energy source, no power production system is without faults, and nuclear reactors are no exception, with their flaws manifesting in the form of safety. Nuclear reactors employ complex systems involving pressure and heat. If any of these systems dysfunctions, the reactor can leak or even explode releasing tons of highly radioactive elements into the environment. Anyone who works at or near a nuclear reactor is constantly in danger of being exposed to a nuclear incident similar to the ones that occurred at the Chernobyl and Fukushima Daiichi plants. These major accidents along with the unresolved problems with the design and function of nuclear reactors, as well as the economic and health issues that nuclear reactors present serve to show that nuclear energy sources are not worth the service that they provide and are too dangerous to routinely use.
