Nuclear Energy
Nuclear energy is energy that is released by reactions within the atomic nuclei, through nuclear fission or fusion. Nuclear energy is also called atomic energy (dictionary.com, 2013). Nuclear energy is produced in nuclear power plants. Nuclear power plants create electricity by heating water to create steam. The steam runs a generator that creates the electricity. Many types of fuels can be used to create heat and generate steam. Nuclear power plants create the heat by splitting atoms. Nuclear power plants use a radioactive element found in rocks called enriched uranium. Enriched uranium is used because when it breaks down in nature it heats Earth’s crust. In nuclear power plants enriched uranium heats water to create steam. Power plants create energy by splitting the nuclei inside each granule of uranium. This process is called nuclear fission (How does energy work, 2013).
Nuclear energy is sometimes considered a renewable energy source. Enriched uranium is a very abundant resource. It is found in most rocks. Despite its abundance there is a finite supply of u...
Nuclear energy must be a consideration for the future with the rapidly depleting supply of fossil fuels. This type of energy can be created through nuclear fission and nuclear fusion. Nuclear fission is the splitting of a heavy atom into two or more parts, releasing huge amounts of energy. The release of energy can be controlled and captured for generating electricity. Nuclear fusion involves bombarding hydrogen atoms together to form helium. In the long run, nuclear fusion has greater potential than fission.
Nuclear Power comes from the process of splitting Uranium Atoms (also called fission), which in turn releases copious amounts of energy in the form of heat. When the atoms are arranged in a reactor, the splitting of an atom will cause nearby atoms to split, forming a chain reaction. As the energy is released, it is sent through coolant tanks full of water, which is then heated into steam. The steam is channeled and used to spin a turbine, which in turn powers a generator,
Uranium has multiple isotopes, the most common isotope is uranium-238, and with uranium-235 being the most popular, but less abundant. Surprisingly, uranium is not necessary for the sustainability of life, and is not chemically toxic (Cox, ...
Many believe that nuclear power plants are a hazard to the people that live around them and the environment in which they are built. However, these assumptions are based mostly on the fact that the nuclear reactors and nuclear power plants of today are built to the same standards that the old nuclear plants from many years ago. Nuclear power today is designed to be much safer than outdated nuclear power plants and have a very minimal chance of causing a nuclear catastrophe. Nuclear power plants are a safe and viable option for generating electricity for the foreseeable future.
Uranium is a rare element and formed not just on Earth but also in space and other planets. It is formed in exploding supernovas, and since it has 92 electrons and 92 protons it is the heaviest naturally produced element. It is radioactive and very harmful and sometimes fatal to humans when contact is made. However it is a sustainable and long lasting source of energy and much better for the environment compared to the more traditional approach to energy, Fossil Fuels. Some scientists say it may be the solution to climate change.
"The tops are leaping off the reactor lip" this was the first warning which the control room received before the destructive explosion in Chernobyl that occurred at 1:23 AM local time. Twenty three minute after the warning in the morning of 26 April 1989, the reactor exploded. The Chernobyl nuclear accident was an unexpected catastrophe that can happen in the history of producing nuclear power. International Atomic Energy Agency (IAEA) defined a nuclear accident as an accident that includes any activities that lead to the release of radioactive material and causes significant consequences. The location of Chernobyl city is in the north of Ukraine near the Belarus border. That nuclear accident happened when in reactor number 4 in the Chernobyl nuclear power in the Soviet Union exploded. Because of that extreme explosion, the radioactive emissions dispensed into the environment and caused immediate deaths, illnesses and many health problems. World Health Association (2013) reports that during the accident, one person died immediately and another one died in the hospital due to the harmful injuries he received. Health World Organization (WHO) (2006) also reports that a few weeks after the disaster 28 people died because of the Acute Radiation Sickness(ARS). The Chernobyl nuclear accident is one of the major disasters in the history of nuclear power which had many serious effects on humans and the environment.
Nuclear power is the generation of electricity from an atomic reaction. (World Statistics: Nuclear Energy Around the World n.d.) Though it produces zero carbon emissions there has been a decline in support for nuclear power and increased its support for alternative energies in the pursuit for a fossil free energy sector. Factors that have resulted in the reduction of support for nuclear energy include nuclear accidents and waste and the positives of renewable energy which include clean energy, sustainable and reduced health and environmental risks.
A. Attention Material: Have you ever thought about energy? Where it comes from and how it powers things? Nuclear energy is one of the many types of energy sources in the world today. It is a non-renewable resource such as coal and natural gas. The first nuclear reactor ever created by man was built in December of 1942. The discovery of building a nuclear power plant was discovered over 150 years ago (Nuclear Power: Villain or Victim?, p. 15).
To begin, nuclear power is produced by nuclear fission, which is the splitting of an atom to start a chain reaction (“11 Facts”). This chain reaction produces massive amounts of heat. Nuclear reactors take advantage of this heat by pumping water into the reactor, which in turn produces steam. The steam then becomes pressurized through a pipeline and exits into a turbine (“How do Nuclear”). The pressurized steam causes the turbine blades to spin, producing power which is linked to a generator for use in the main power lines. When the steam passes the turbine blades, it goes past cooled pipes and condensates (“How do Nuclear”). After the condensation process is finished and the steam reverts back to water, it is pumped into the reactor again, thus completing the process of producing nuclear-based power.
As a source of energy, nuclear energy provides a safer alternative, for the production of energy for large-scale consumption. There are two different types of nuclear energy; nuclear fission and nuclear fusion. Nuclear fission is the process in which a nucleus spits into two or more smaller nuclei. Nuclear fusion is the process in which two nuclei fuse together to form a larger nuclei. Nuclear reactors can become unstable creating an uncontrollable nuclear reaction. The effects of this can be seen in Chernobyl. Reactors have been designed safer after this disaster.
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...
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.
Nuclear energy is generated by a process called fission. Fission occurs within the reactor of a nuclear power plant when a neutron is fired at an atom of uranium causing it to split and release subsequent neutrons.1 These are able to crash into other uranium atoms causing a chain reaction and releasing a great deal of heat energy.
Nuclear power, the use of exothermic nuclear processes to produce an enormous amount of electricity and heat for domestic, medical, military and industrial purposes i.e. “By the end of 2012 2346.3 kilowatt hours (KWh) of electricity was generated by nuclear reactors around the world” (International atomic energy agency Vienna, 2013, p.13). However, with that been said it is evident that the process of generating electricity from a nuclear reactor has numerous health and environmental safety issues.
The most important use of radioiactivity is in the production of nuclear energy. There are two basic ways in which nuclear energy can be released from ...
