There are a lot of great discoveries and cool stuff in science but some people might not know about them. For example: nuclear energy, nuclear power plant, and chemistry of fission, etc. Some people might not even know why radiation is dangerous, or what happened in the Yucca Mountain. It is also good to know accidents in a nuclear power plant because it doesn’t give a fantastic result. It caused some accidents at Chernobyl and the terrible disaster in japan caused by the tsunami. But nuclear energy is not just bad it can be good too, some advocates think that nuclear power is good at burning coal or natural gas. The nuclear energy can be compared to the yinyang because it has some good but it also has evil or bad.
First let’s see what nuclear energy exactly mean. According to Google.com nuclear energy means the energy release by a nuclear reaction, more like fission or fusion. What is fission or fusion? Fission is the process of splitting into parts; for example, an isotope of uranium splits into fragments. If you want to calculate the energy released in a mass destruction in a nuclear fission, you should use Einstein’s equation E=mc2. Fusion is the procedure of liquefying or melting by heat. It is also good to know that a nuclear energy plant is a thermal power station in which the heat source is a nuclear reactor. In April 2014 the IAEA reported that there are a lot

...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. Coal is the most source used of electric energy, coal and nuclear energy contribute 50 percent of the power in Texas. Even though nuclear power plants generates like 20% of the electricity in
Sandoval 5 the U.S two thirds of respondents don’t want to live 10 miles close to a nuclear reactor. Utilities find nuclear power less, there are new solar photovoltaic installation in the U.S are springing up.
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.
Radioactive Waste One of the most talked about opposition to nuclear fission is the radioactive waste it produces. 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, which is highly radioactive but can still be disposed of. Low-level waste is the contaminated items that have been exposed to radiation.
Carbon, Max W. Nuclear Power: Villain or Victim?: Our Most Misunderstood Source of Electricity. Second ed. Madison, WI: Pebble Beach, 1997.
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.
(Action): If we don’t do our part to stop the expansion of nuclear power plants, the future of our planet will be bleaker. Every year, thousands of more pounds of nuclear waste will be buried underground and the damage to our environment increases. There are more efficient energy sources other than nuclear power and we must do our part today to prevent a catastrophic future for our children. The dangers that nuclear power plants pose for the United States are very real. There are many alternative renewable sources of energy available to us such as wind and solar power, which provide a much safer and efficient alternative to nuclear power. You alone have the power to speak up and act against the expansion of this dangerous energy. The future of our environment’s safety and our nation’s energy supply lies in your hands.
...nce World War II to the present day, the technology of nuclear power has increased significantly in terms of energy output and safety. The energy efficiency of nuclear power is far superior to its counterpart fossil fuel and renewable energy. Compared to fossil fuels, tiny amounts of fuel used by nuclear reactors is equivalent to a large sum of coal. This is a no brainer. Why mine a ton of coal when a little uranium can be used to gain the same amount of energy? Not only is it efficient, it’s safe to use. Used fuel is packed away in storage safely, so there isn’t any chance of radiation leaking out. In the present day, nuclear power incidents haven’t been occurring lately. Advancements in technology and equipment used have made nuclear energy a very reliable and safe source of energy. With today’s energy needs, nuclear power has the ability to keep up in the race.
In conclusion, there are different opinions on the issue of the use of nuclear energy. Nuclear energy is only one of many energy options. Nuclear power can decrease pollution to the environment because it does not produce harming gases like other plants do. However, there are also drawbacks that can influences human health by emitting radioactive substances. Thus, all parties should make a deeper research and analysis based on the argument to decide the use of nuclear energy as a safe and cost effective source of energy.
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 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.
In 1945, when the Americans bombed Hiroshima, Japan, approximately 140,000 men and women were instantly killed by the effects of American nuclear defense. With such extreme brutality and force how many people must die for one to finally realize the strengths of nuclear bombs and what damage they can cause. Nuclear weapons should be outlawed because they kill thousands of innocent humans at a time, destroy the environment, and inviolate human’s right to moral and personal freedoms.
The use of nuclear power in the mid-1980s was not a popular idea on account of all the fears that it had presented. The public seemed to have rejected it because of the fear of radiation. The Chernobyl accident in the Soviet Union in April of 1986 reinforced the fears, and gave them an international dimension (Cohen 1). Nevertheless, the public has to come to terms that one of the major requirements for sustaining human progress is an adequate source of energy. The current largest sources of energy are the combustion of coal, oil, and natural gas. Fear of radiation may push nuclear power under the carpet but another fear of the unknown is how costly is this going to be? If we as the public have to overcome the fear of radiation and costly project, we first have to understand the details of nuclear energy. The known is a lot less scary then the unknown. If we could put away all the presumptions we have about this new energy source, then maybe we can understand that this would be a good decision for use in the near future.
We depend on energy; nothing in our daily lives could be possible without it. Electricity primarily comes from burning fossil fuels or using nuclear reactors. But the plain truth is, we are running out of fossil fuels. Our known oil deposits will run out in approximately 35 years, and if we increase the use of natural gas and coal to make up for the energy loss, our natural gas will last for 45 years and coal deposits will deplete in 75 years.
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 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.
The world that we live into today affords us the expectation that the flip a switch will turn the lights on. As populations increase and developing nations undergo dramatic economic growth, this energy demand will only continue to grow. The International Energy Agency (IEA) believes that “the world’s energy needs could be 50% higher in 2030 than they are today” (ElBaradei). Given this projected growth, it is necessary for world leaders must take action to secure the energy supply. Meaning that world leaders need to start seriously considering an alternative to non-renewable energy sources. “In 2012, the United States generated about 4,054 billion kilowatt-hours of electricity. About 68% of the electricity generated was from fossil fuel (coal, natural gas, and petroleum), with 37% attributed from coal” (U.S. Energy Information Administration). The fossil fuels that are used to supply over half of our country’s energy are in finite supply and are increasing in price to astronomical heights.
