Chernobyl
Chernobyl was the greatest nuclear disaster of the 20th century. On April 26th, 1986, one of four nuclear reactors located in the Soviet Union melted down and contaminated a vast area of Eastern Europe. The meltdown, a result of human error, lapsed safety precautions, and lack of a containment vessel, was barely contained by dropping sand and releasing huge amounts of deadly radioactive isotopes into the atmosphere. The resulting contamination killed or injured hundreds of thousands of people and devastated the environment. The affects of this accident are still being felt today and will be felt for generations to come.
Nuclear power has always been a controversial issue because of its inherent danger and the amount of waste that the plants produce. Once considered a relatively safe form for generating energy, nuclear power has caused more problems than it has solved. While it has reduced the amount of traditional natural resources (fossil fuels), used to generate power like coal, wood, and oil, nuclear generating plants have become anachronisms. Maintaining them and keeping them safe has become a problem of immense proportion. As the plants age and other technology becomes available, what to do with these “eyesores” is a consuming issue for many government agencies and environmental groups. No one knows what to do about the problem and in many areas of the world, another nuclear meltdown is an accident waiting to happen. Despite a vast array of safety measures, a break in reactor pipe or a leak in a containment vessel, could spell another environmental disaster for the world.
In addition to the potential dangers of accidents in generating stations, nuclear waste is a continuing problem that is growing exponentially. Nuclear waste can remain radioactive for about 600 years and disposing these wastes or storing them is an immense problem. Everyone wants the energy generated by power plants, but no one wants to take responsibility for the waste. Thus far, it is stored deep in the earth, but these storage areas are potentially dangerous and will eventually run out. Some have suggested sending the waste into space, but no one is sure of the repercussions.
Nuclear power plants should be dismantled and replaced with safer energy generating sources.
Every since the industrial revolution, society has moved to jobs, factories, manufacturing goods and products, and larger cities. This process called industrialization is when an economy modifies its way of living from an agriculture based living to the production of merchandise in factories. The manual labor that is required for farm work is replaced with mass production on assembly lines. Andrew Blackwell visits this idea of industrialization in Visit Sunny Chernobyl but to a higher extent. Blackwell states “today that society is an industrial one, resource hungry and plant-spanning, growing so inefficiently large, we believe that it is disrupting its own host… It’s not just about living sustainably. It’s about being able to live with ourselves,”
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

Hopefully, with accurate analysis and innovation, my research will teach the world of its past so this disaster doesn’t occur in the future. B - Summary of Evidence Chernobyl (chrn byl) is an uninhibited city in north Ukraine, near the Belarus boundary, on the Pripyat River. Ten miles to the north, in the town of Pripyat, is the Chernobyl nuclear powerstation, site of the worst nuclear reactor disaster in history ("Chernobyl", Columbia Encyclopedia). To specify, on April 26, 1986, Unit Four of the Chernobyl nuclear reactor exploded in Ukraine, injuring human immune systems and the genetic structure of cells, contaminating soils and waterways. Nearly 7 tons of irradiated reactor fuel was released into the environment—roughly 340 million curies.
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.
The seemingly limitless power of the atom has been exploited by scientist around the world ever since the Enola Gay flew over Hiroshima on August 6th 1945 and dropped the second atomic bomb, revealing to the world this new form of energy. The key to harnessing the energy from nuclear fission in a stable reaction soon followed, starting the Nuclear age. Russia, emerging as a superpower and major industrial center found special needs for nuclear fission. From the period of 1980-1990, the Russian Federation’s Gross Democratic Product grew 2.8% each year, comparable to the United State’s 2.9% each year. To fuel this growth, the only cheap, affordable, efficient energy production means was nuclear energy. The fission of 1 lb of uranium-235 produces as much energy as 1,500 tons of coal. The Cold War only escalated this demand, and soon, reactors served dual purposes of providing energy, as well as producing weapons grade plutonium. In fact, the first reactors were designed to manufacture plutonium, not to generate electricity. Everything has its flaws though, and nuclear energy was no exception, with one of the heaviest reprucussions in the event of an accident. April 26th, 1986 is an excellent example of that. Chernobyl was not the first nuclear reactor mishap the world has encountered, but it was definitely the worst for many years to come. Previous accidents such as Three Mile Island in the United States, Indian Point near New York, and a partial meltdown at Leningrad predated Chernobyl. However, the 100 million curies of radiation emitted by the RMBK-1000 reactor put Chernobyl on an entirely different scale compared to the previous accidents. Failure to effectively prevent, contain, and effectively respond to the radiation emit...
"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.
Many of the causes of the disaster at the Chernobyl nuclear reactors were from the lack of safety and the failure to follow safety features. This horrible incident shows us many lessons that should be learned. A few reasons for the Chernobyl power plant to rupture was due to the amount of control rods that were used. Where a minimum of 30 controls rods were required, only 6 to 8 control rods were used. The main reason that cause the core to actually ruptured was due to a sudden rise of the temperature in the reactor during the manual removal of control rods in a test which lead to the instability of the reactors. As the temperature rose, the core ruptured. A few reasons behind the Chernobyl nuclear power plants core to overheat were due to a few overlooked problems that were not taken care of. The Chernobyl Nuclear power plant used steam as a coolant, where water is a better coolant than steam for it also acts as a moderator, and second, it was found that the reactor’s emergency cooling system was disabled. These lack of actions lead to the catastrophic consequences at the Chernobyl power plant.
In the early morning of April 26th, 1986, two explosions tore through the Chernobyl nuclear power plant leaving behind nothing but rubble, nuclear fallout, and the infamy of what will probably long be called the worst nuclear disaster in history (World Nuclear Association, 2013). The cities of Chernobyl and Pripyat remain ghost towns due to extremely high levels of radiation still present 28 years after the explosion. The undeniable environmental effects of the blast couple with the severe health effects to earn the Chernobyl explosion its infamy.
"Chernobyl" is a nuclear reactor accident occurred in the Chernobyl nuclear power plant in Ukraine. The accident was by far the most serious nuclear disaster. It pollutes the many areas around and increases the incidence of cancer around the inhabitants. Since the Chernobyl accident, the Soviet Union suffered a heavy blow disaster, while enhancing the worldwide nuclear power industry for safety concerns, and slowed the progress of a series of nuclear power engineering. Disaster occurs mainly due to the failure of the reactor design, and employee carelessness and violation of the rules. The response to the disaster was also not adequately handled and this increased casualties, but lacking of information and the government reluctant to recognize
One major unresolved issue arises as the result of using nuclear power: what happens to waste generated in this process. As of right now, the waste is stored on site or in deep geological repositories. However, with what was to be the country’s end all storage site (the Yucca Mountain repository) no longer an option due to recent legislation, long-term storage seems unfeasible. In addition, as more nations move towards reprocessing, there are experts and lawmakers in this country who have been looking into reprocessing the country’s nuclear waste as well. While many experts say that reprocessing is the best solution for freeing the country of the nuclear waste issue, there are others who say that reprocessing is simply too dangerous and expensive.
On April 26th 1986, the world’s worst nuclear accident occurred at the Chernobyl Nuclear Power Plant in Ukraine. The explosion sent a ‘cloud of radiation’ throughout the area, including Belarus, and much of the western Soviet Union and Europe, releasing 400 times more than the atomic bombing of Hiroshima. This is because a nuclear power plant contains a lot more nuclear material than an atomic bomb.
Nuclear power plants produce nuclear waste or fission product which is still radioactive after splitting the original atom. “The large majority of the energy is released instantaneously but the rest of it comes out from the fission products over the years. That slowly released energy is what makes nuclear waste a hazard.” (Touran). That hazard can affect both humans and the environment which the waste is placed in. Nuclear waste is also hard to get rid of. The methods used take a long time to dispose the waste, especially high level waste. “High level waste decays into intermediate level waste over many thousands of years.” (Nuclear Power). Intermediate level is a high level of radiation which is hard to contain. Nuclear waste is a danger to the workers in these factories due to the health problems they could have. Also many other people can be affected by the radiation that are taking in. “Nuclear Power Plants cause between 600-1000 deaths a year per million people” (Nuclear Power Plant Accidents). These death of innocent people are just because of the usage of radiation. Nuclear waste is stored safely in containers in a pool just for the containers to reduce radiation (Nuclear Power). Although they are stored there radiation can still come out and the water used is now polluted. Today we are running the risk of having no more water. This is just using up more water were it can be used in a everyday life. Nuclear power plants should stop being used because all of the waste it produces and also because accidents can be
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.
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.
