Power That is Not Worth the Price Ever since the Industrial Revolution began in the late eighteenth century, humans have consumed and utilized available energy sources. This formed civilization’s dependence on the usage of power to maintain human development and wellbeing. People have used resources such as coal, solar panels, fossil fuels, and turbines to achieve accessible amounts of power that they can consume in a variety of ways. In recent years, much debate has appeared regarding whether or not nuclear energy is a form of power that should be used to replace standard types of energy sources. To some people, nuclear power presents as a better alternative to usual sources. In reality, nuclear energy contains massive risks that outweigh …show more content…
Though errors can contribute to nuclear disaster, what happens when a natural disaster occurs and the effects are made worse by a man made nuclear power plant? The Fukushima Accident was the result of when a 15-metre tsunami disabled the power supply and cooling of three Fukushima Daiichi reactors, causing a nuclear accident in March 2011. There have been no deaths or cases of radiation sickness from the nuclear accident, but over 100,000 people were evacuated from their homes to ensure this. Official figures show that there have been well over 1000 deaths from maintaining the evacuation, compared to little risk from radiation if early return had been allowed (World Nuclear Association). The issue with the Fukushima accident is the fact that nuclear power plants pose a great threat because no one knows exactly what could happen when procedures in the plant do not go perfectly. According to a professor at the University of Wisconsin School of Medicine and Public Health, "The real issue is that the use of nuclear power is forcing humankind, and indeed the whole ecosystem, to participate in a particularly cruel and totally uncontrolled experiment. Given the scientific evidence that there is no safe dose of radiation, this is an experiment that has already gone awry”(Patterson, Jeffrey). Nuclear energy is essentially a gamble that should not be accepted, and the energy should not be created …show more content…
However, that claim is not correct. People believe that they need an alternative to resources such as oil and other limited materials. They believe nuclear energy created from uranium is renewable and available, but unfortunately they are not accurate. Uranium is a material that is mined, so it is not available in many countries. It is also very scarce, and is estimated to be almost completely extracted from the earth in 50 to 60 years. Following that there will be no uranium to use in nuclear energy production. Due to uranium’s status as a dangerous and limited resource, it is not considered a renewable source of energy. Another incorrect claim that is often made is that nuclear energy is environmentally friendly. Nuclear power is referred to as a clean source of energy due to the absence of carbon dioxide emissions. Though the plants themselves don’t emit carbon dioxide gas during operation, plants release a large amount of carbon dioxide through the act of mining for uranium. The environment can also be damaged by radioactive waste. For instance, after the Chernobyl Accident, many trees located in 10 kilometers surrounding the plant were killed by the radiation levels. Nuclear energy is involved with the emission of carbon dioxide and the damage of environmental organisms through radiation damage, proving that nuclear
power is not the cleanest energy source. However nuclear energy is cheaper than fossil fuels, and the
Following a severe earthquake and Tsunami, 3 reactors were damaged, similar to Chernobyl. However, the event was contained with minimal nuclear leaks and no deaths. The surrounding area has already been deemed safe. Despite this, many still fear events such as this. The problem is, they should not. “As a nuclear engineer, it is depressing to read the recent reports on the Fukushima nuclear incident — not because of the incident itself (at this point I strongly believe that we will remember Fukushima as evidence of how safe nuclear power is when done right) — but because the media coverage of the event has been rife with errors so glaring that I have to wonder if anyone in the world of journalism has ever taken a physics class.” (Yost, Keith. What happened at the Fukushima reactor? Mit.edu) What he is essentially saying is that the nuclear reactors were properly managed during the event, and a major incident was avoided. He believes it instead to be a testimony to the safety of nuclear
The Chernobyl Nuclear has also affected the environment. Such as the food products in the Forest like mushrooms, berries containing high levels of long-lived radioactive caesium and this pollution is expected to remain high for several decades or so. For example, the accident led to high pollution of caribou meat in Scandinavia. Water bodies and fishes became polluted as well with radioactive materials. The accident has actually affected many animals and plants living within 30-40 km of the . There was an increase in mortality as in increasing of deaths in an area and a decrease in reproduction and some genetic anomalies in plants and animals are still reported
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.
Nuclear power has no place in having a safe, clean, sustainable future. Today, the manufacturing of nuclear power plants has become a critical topic throughout the world that many strongly believe should be stopped. Nuclear Power is not safe anywhere in the world nor is it environmentally friendly. Nuclear power plants are truly something that could cause mass destruction in the world and has the potential to wipe out a whole country with ease. Despite proponents’ that claim that nuclear power is safe, there is a history that proves otherwise and marks a number of disasters caused by nuclear power plants.
I. (Gain Attention and Interest): March 11, 2011. 2:45 pm. Operations at the Fukushima Daiichi Nuclear Power Plant continued as usual. At 2:46 pm a massive 9.0 earthquake strikes the island of Japan. All nuclear reactors on the island shut down automatically as a response to the earthquake. At Fukushima, emergency procedures are automatically enabled to shut down reactors and cool spent nuclear fuel before it melts-down in a catastrophic explosion. The situation seems under control, emergency diesel generators located in the basement of the plant activate and workers breathe a sigh of relief that the reactors are stabilizing. Then 41 minutes later at 3:27 pm the unthinkable occurs. As workers monitored the situation from within the plant, citizens from the adjacent town ran from the coastline as a 49 foot tsunami approached. The tsunami came swiftly and flooded the coastline situated Fukushima plant. Emergency generators were destroyed and cooling systems failed. Within hours, a chain of events led to an explosion of reactor 1 of the plant. One by one in the subsequent days reactors 2, and 3 suffered similar fates as explosions destroyed containment cases and the structures surrounding the reactors (Fukushima Accident). Intense amount...
...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.
The purpose of this report is to investigate the different views and opinions on the safeness and cost effectiveness of nuclear power compared to other forms of energy. This report will explain the issues and background of the debate, the importance of the issue, and the parties who are involved in this debate with their thoughts.
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...
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).
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.
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.
The greatest disadvantages of nuclear energy are the risks posed to mankind and the environment by radioactive materials. ‘On average a nuclear plant annually generates 20 metric tons of used nuclear fuel cla...
In the search for alternatives to fossil fuels, scientists and policy makers have focused on three options: nuclear power, energy from biomass; and a combination of wind, water, and solar power. Nuclear power, however, is much more costly and runs the risk of having it fall into the wrong hands where it could be turned into a weapon of mass destruction. The third option entails wind turbines, photovoltaic power plants and rooftop systems, concentrated solar thermal power plants,...
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.
