Nuclear energy holds great interest for those looking for a sustainable energy source. Our current energy requirements are met by the use of fossil fuels. However, there exist some substantial problems with fossil fuels. Not only are they limited, but they also contribute to the carbon dioxide emissions and thus to global warming. Use of nuclear energy will cut the percentage of carbon emission as it does not involve any burning. Instead, the splitting of nuclei of atoms provides the energy. Using nuclear power instead of coal for electricity generation will cut 2.4 billion tons of carbon dioxide emission (Brook). As with any type of alternate energy proposals, there are issues involved. One of such issue for nuclear energy is waste …show more content…
Currently, the most common way to manage HLW is to store it in a geological repository which is a tunnel under the surface in a stable geological location far from the population. However, this technique proves to be unsafe since there is a possibility of there being a leak and the nuclear waste being released into the environment. Even a small leak can result in a large catastrophe (Xie). The long-term effects of the bombing of Hiroshima and Nagasaki fully demonstrate the dangers that radioactivity exposure can present. Radioactivity exposure resulted in the increased risk of Leukemia, breast, thyroid, and lung cancer as well as degeneration of nuclei of cells among the survivors of the atomic bomb (Roe). Transmutation provides a way to change the long-lived fission products into short-lived ones. The change occurs when the atom is bombarded with a nucleus in a nuclear reactor (World Nuclear Association). Partitioning is performed along with transmutation and it is the process through which radioactive isotopes are taken out of the HLW for transmutation (Abderrahim). Transmutation and partitioning can reduce the nuclear waste problem in magnitude.
The waste produced with the production of nuclear energy has always been a substantial problem. The transmutation of nuclear waste not only reduces radioactive waste but also leads to better use of present raw material and reduction in the number of actinides. Currently, the isotope 235Uranium is used
Transition: Now that we know how nuclear energy is produced, let’s talk about some ways it is utilized in modern society.
Disposal of the high level nuclear waste that comes from nuclear power plants continues to be a big problem. It has been challenging and costly to find safe ways to store this waste. According to a report from the U.S National Academy of Sciences, it will take 3 million years for radioactive waste stored in the U.S. as of 1983 to decay to background levels (thinkquest.org). Who wants this amount of waste stored in the environment where they live? Currently in the U.S. nuclear power plants produce 3,000 tons of this high level waste each year (thinkquest.org). If nuclear power continues to be produced, this amount of waste will only continue to increase, causing a bigger dilemma as to what to do with the waste. As the waste is removed from the plant it still contains a high level of radiation. Exposure to radiation whether it occurs in the moving process or leakage from storage not only has a negative impact on the environment but also can pose a major health threat to humans. Based on the level of exposure, symptoms to humans can range from nausea and headaches to damage of nerve cells, loss of white blood cells and even death (think .org). The potential risk of exposure is not worth human life.
The United States should use nuclear energy to help supplement energy demand because it’s cost-effective, safer for the environment, and a more reliable source of energy than any of the other types of fuel. Some of the topics of interest are cost-effectiveness, recycling options, long term storage options, environmental protection technologies currently being used, and a breakdown of how nuclear energy out performs other sources of power year round.
Today, a considerable amount of energy is provided by nuclear energy. The technology is well organized and developing every passing day and as a result the cost of operation is falling. Using radioactive resources to produce energy generates waste. Waste that contains radioactive materials is called nuclear waste. The secure and environmentally-friendly disposal of nuclear waste is a crucial aspect of nuclear power programs. [1]
Throughout history, the source of energy that powers the world has advanced alongside technology. The power on which civilization thrives has to be in accordance to the demand at which it is required. As technology evolves, objects from which energy can be extracted can expanded exponentially. In the status quo, the United States is trying to limit the greenhouse gas emissions instead of just switching power sources which is the wrong direction they should be going in. [Thesis] Instead of wasting their time and money investing in burning coal as their main source of power, countries and their governments need to assist in the transition to a more cost effective and efficient form of energy in the form of nuclear energy.
Today, as much as we know about nuclear power is one of the most powerful and fresh energy, compared to any carbon dioxide producing fuels like coal or oil. It is a very cost effective “cheap” source, but with a major downside. Obtaining it is a rather complex chemical procedure, and the outcome is not only precious power, but also hazardous waste. This
The necessity for a new type of energy increases with every year. Energy consumption rates are increasing continuously, and with them, pollution and wastes directly harming the Earth and her atmosphere. While other energy competitors constantly fell short of impacting fossil fuels enough to significantly lower their usage rates, nuclear energy can not only compete against the highly efficient yet harmful fossil fuels but can reign as king as a more efficient and cleaner source of energy.
The spent fuel rods and the other products produced by the nuclear fuel process are highly reactive. This waste must be stored in very safe and secure locations for tens of thousands of years, which is periods “longer than the history of most governments the world has seen” as the former Atomic Energy Commission put it (Carson). The uranium that is used in the reactors has a half life, that is long it takes for half the nuclei in the radioactive material to decay, of 10,000 years, while plutonium, another nuclear fuel, has a half life close to 25,000 (Carson). Some say that it is too much of a burden to place on future generations to be able to properly monitor and maintain waste dumps that will last 20 times the length of known civilization. As Michio Kaku put it in Nuclear Power: Both Sides “The controversy surrounding [nuclear] waste boils down to one question- can we trust and man made structure to isolate high-level waste for tens of thousands of years given our always-changing social institutions and the vagaries of war, revolutions, and social upheavals”
There have been lots of nuclear accident around the world. One of the accident that had a major impact on the world was the Chernobyl disaster. The disaster took place on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine. The disaster was caused by a reaction explosion induced by design faults and staff application errors. The accident took place in the course of scheduled tests to check the power supply mode in the event of external sources loss. Even after 10 days, explosions and ejections of radioactive substances continued. The release of radiation and radioactive substance polluted the places within 30 km of Chernobyl, and those areas have been closed for a long period of
The steam spun the wheel of the turbine with a Whoosh. The ecstasy of finding a new energy source is ineffable, and when found, the discovery always immediately prompts a race to use this newfound source. In accordance with this behavior, many sought to integrate nuclear power into society upon its development. The difference being nuclear energy is far more complicated and powerful than anything the field of energy has dealt with thus far. There are two types of nuclear reactions, fission and fusion; working reactors only using fission currently. In fission a neutron reacts with Uranium-235 to produce energy, two fragment nuclei, and multiple neutrons to continue the reaction. Meanwhile, in fusion two hydrogen isotopes react to produce energy, protons, neutrons, and Helium. As a consequence of these processes ' complex and formidable natures, there is a hesitance to their utilization as it is difficult to discuss the complexities of the procedures with the public without some misinterpretation. Despite the benefits found in nuclear power, it still undergoes harsh debate as governments oppose giving money to such an unexplored area of science. Yet, an increase in funding for U.S. nuclear programs would prompt advancements that replace less effective energy sources, creating opportunities for specialization in the field.
It is estimated that at today’s rate of consumption, the earth has about fifty years left of fossil fuels. In contrast, due to the very small amount of uranium needed to create a huge amount of energy, the supply of nuclear energy is almost infinite [Jiskha].
The world as we know today is dependent on energy. The options we have currently enable us to produce energy economically but at a cost to the environment. As fossil fuel source will be diminishing over time, other alternatives will be needed. An alternative that is presently utilized is nuclear energy. Nuclear energy is currently the most efficacious energy source. Every time the word ‘nuclear’ is mentioned, the first thought that people have is the devastating effects of nuclear energy. Granting it does come with its drawbacks; this form of energy emits far less pollution than conventional power plants. Even though certain disadvantages of nuclear energy are devastating, the advantages contain even greater rewards.
The disposal of nuclear waste is quickly becoming the most important issue facing the environmental community today. Nearly twenty percent of our nation's electricity is being supplied by approximately 100 nuclear power plants that are operating in the United States. Currently, most of the nuclear waste created by these power plants is being housed temporarily in storage facilities and although the total amount of nuclear waste produced in one year is small, the need to find a permanent method of disposing this waste is rapidly growing.
The use of nuclear energy is a big topic for debate. Many countries have fully embraced it while others, such as the U. S., haven’t. Nuclear energy is feared for its danger and scorned because of its wastes. On the other hand, nuclear energy does have some pros like cheaper cost of energy and environmentally safe. Reactor breeders show great promise in nuclear waste, but are it enough to convince the nation?
Nuclear energy could be the future of energy and potentially solve the energy crisis problem. Nuclear energy is a sustainable energy source and it can provide millions of times the amount of energy output from a fixed mass of fuel than any other energy source, such as fossil fuel, for the same mass of fuel. Nuclear energy is also very clean for the atmosphere. It produces no greenhouse gases at all. However, nuclear energy can be very harmful to both people and the rest of the natural environment if not managed well. Nuclear meltdowns etc. can release
