Nuclear energy is a topic scholars and the average person discuss and argue whether they are for it or against it. Inside the nuclear reactor, energy is produced by the fission of Uranium atoms. Other isotopes of Uranium and Plutonium are used in reactors. Fission is the process in which a single atom of Uranium absorbs a slow neutron causing it to become unstable and split into two nuclei causing a chain reaction of splitting. A massive amount of energy is released when the atom splits. It is then captured and turned into electricity. Nuclear energy supplies an abundant amount of power for the United States, but there are still problems with this type of energy. During the process of fission, radioactivity is released and the used Uranium rods are still extremely potent to the environment. This waste from the nuclear reaction is what is causing all the debate between people because the waste has not been able to be stored or handled safely without some risk. If the radioactivity is let out into the open, the byproducts are hazardous. Personally, I support the continuation of the United States’ implementation of nuclear power because there are ways to safely use, handle and store the waste; the nuclear reactors are well protected, there are good and bad effects from the production of power, and there is a way to address the public sentiment of those who oppose it.
The long lasting problem of storing nuclear waste is upon us now and needs to be solved. The radioactive waste eventually decays or reduces as time goes on. Most of the waste is low-level waste which releases alpha and beta radiation which can be easily shielded; however, some of the waste-like spent fuel rods release gamma rays that are extremely strong and dangerous....

...ation of nuclear power in the United States because it is a cheap, long lasting clean energy source. Continuing on, it also is a safe power source when used properly and there can be storage for its harmful waste. The waste can be placed in a large, safe facility nowhere near civilization and the used rods can be partially reused when separated from the radioactive part. Nuclear energy reactors are highly secure and the report card in the US has shown how controlled it can be. Next, there have been some harmful effects from this power source when not contained, but overall nuclear energy doesn’t pollute our environment compared to coal and oil. Lastly, there is a way to handle those who disagree by showing and giving examples of the safety and efficiency of nuclear energy. The fate of this arguable power source is a choice the United States will soon have to decide.
One of the most talked about opposition toward nuclear fission is the radioactive waste it produces. A radioactive waste is what is left behind after using a reactor to make electricity. There are two levels of waste, low and high, but both are regulated by the Department of Energy and the Nuclear Regulatory Commission. High level waste is made up of fuel that’s been used directly in the reactor that is highly radioactive but can still be disposed. Low level waste is the contaminated items that have been exposed to radiation. The nuclear wastes are then stored in a safe and secure location with different types of methods such as wet storage, dry storage, and away from reactor storage. Wet storage is the main method of disposing the waste because it is the
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.
There are many sources of energy today, and the best source of it is constantly being sought after, one source stands out above the rest. Nuclear energy is simple in theory, yet it may be one of the most controversial sources of power. Nuclear energy works using reactors built to split the atoms (nuclear fission) of the fuel to produce heat. This heat evaporates the cooling agent (usually water) into steam which turns turbines to create electricity. Nuclear energy should be allowed, because it produces an abundance of electricity, as well as being a clean source of energy with no harmful emissions. Nuclear energy is the future of clean, environmentally friendly energy.
After the United States developed the atomic at the end of World War II, interest in nuclear technology increased exponentially. People soon realized that nuclear technology could be used for electricity, as another alternative to fossil fuels. Today, nuclear power has its place in the world, but there is still a lot of controversy over the use of nuclear energy. Things such as the containment of radiation and few nuclear power plant accidents have given nuclear power a bad image. However, nuclear power is a reliable source of energy because it has no carbon emissions, energy is available at any time, little fuel is needed for a lot of energy, and as time goes on, it is becoming safer and safer.
After the first few days of the bombings of Hiroshima and Nagasaki Americans, without knowledge of the aftermath of these cities, began cheering and celebrating as the bombings marked the end of World War II. Also, this event showed that Americans would be the ones who would lead the world into the nuclear age. In a Gallup Poll taken from August 10-15, 1945, Americans were asked whether or not they approved or disapproved of the use of atomic bombs on Japanese cities, 85 percent approved, ten percent disapproved and five had no opinion.30 then when asked if the development of the atomic bomb was a good or bad thing, 69 percent said it was a good thing, 17 percent said it was bad, and 14 percent had no opinion (Steele).
Nuclear energy is produced during the process named nuclear fission or nuclear fusion. The development of nuclear energy started in the 20th century and there is now worldwide recognition for using nuclear energy. Popular countries that operates nuclear power are United States, France, Japan, and Russia, the nuclear energy generates up to 6% of the world’s electricity supplies. Even though the energy is mostly used by many countries, but it may causes side effect to the living things in the environment. (WNA, 2012)
Nuclear power is a growing source of energy to most of the world for many benefits. People doubt the significant of nuclear power because of one accident. Due to this accident, the world has only seen the flaws in nuclear power and not the many benefits it has to offer. Nuclear power would benefit worldwide if people would let go of the past and look towards the future. Nuclear power is a better alternative energy because of its economic and environmental benefits.
The use and management of radioactive materials is not a topic that is generally discussed in abundance to everyday citizens. Many people do not know what radioactive waste is or even the effect that it can have on the human body. Radioactive waste is a type of waste that has some type of radioactive material inside of it. The managing of this radioactive waste is extremely important because it can cause damage to living tissue. Without a place to properly dispose of or contain, the radioactive waste can contaminate our water, food, air, or even our land. If this happened it would be detrimental to all human’s health, causing many different problems throughout the world not only with the health of the population, but problems with the environment as well. Therefore it is vital that we have somewhere to put these radioactive wastes.
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...
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.
Nuclear energy has is an overall success and continues to be because it is a reliable, efficient energy source that produces minimal pollution. Although it is a efficient energy source, it is also a massive destructive force that has been used in the past and can be used in the future if not properly defended against. America today can learn from instances in the 20th century such as the atomic bomb drops, exploration of fusion reactions, the knowledge gained from the three mile island accident, and from espionage. Nuclear technology is basically that manipulation of atoms in their current state. Usually radioactive elements such as high-grade plutonium or uranium are used in order to create a massive radioactive reaction that have the potential to obliterate any object in its way leaving a lasting negative effect on the environment. Nuclear energy was mainly researched for the atomic bomb droppings that occurred in 1945 as a result of Japanese oppression during World War II. The science of atomic manipulation, atomic radiation, nuclear fission and nuclear fusion was first developed in 1895. Research began to significantly speed up when the government took a large interest in the destructive force that nuclear weapons had the potential to hold. The only reason that the world ever had the experience of nuclear energy was because of World War II and oppression. Nuclear Energy came with a price of thousands of lives, that were not rightfully taken, but without those lives lost, our world would be different today, and we continue to learn from the mistakes and from the successes that we have had with nuclear technology.
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...
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.
To save words we not go into the basic details of these radiations but these radiations make the radioisotopes our friend or foe. These radiations revolve round the issue of their use and disposal. Interestingly, both use and disposal are issues of concern. Disposal is an issue because the waste is non-biodegradable and the harmful radiations from them could cause cancer and alter genes in the DNA etc. The use of radioactivity is by itself an issue. Is it safe to use? Where shall the nuclear power plant be located? Where will the waste go?
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.
