Introduction
The Chernobyl nuclear facility had four working reactors at the time when accident happened. It is located in Ukraine about 20 km south of the border with Belarus.
A test on electric controlling system was ran in the morning of 26April1986. The accident happened because of a series of basic engineering blemish in the reactor and inappropriate actions of the operators. The reactor was being operated under very dangerous situation in which the safety systems had been switched off. This is a situation which will cause an uncontrollable power surge to occur. The nuclear fuel to overheat and led to a series of steam explosions that severely damaged the reactor building and completely destroyed the unit 4 reactor due to the power surge.
Numerous fires on the roofs of the reactor building as the explosion started and the machine hall were extinguished by firefighters after a few hours. Approximately 20 hours after the explosions, a large fire started as the material in the reactor set fire to combustible
It has in a total of four nuclear reactors of the RBMK-1000 design, with units 1 and 2 being constructed between 1970 and 1977, while othe same design units 3 and 4 were completed in 1983. At the time of the accident, two more RBMK (High Power Channel-type Reactor) reactors were under construction at the site. An artificial lake of some 22 square kilometres, the southeast of the plant, situated beside the river Pripyat, a tributary of the Dniepr, was constructed to provide cooling water for the

    Humans feel a need to transcend boundaries even if the consequences are numerous. A prime example of this is found in Chapter 1 of Visit Sunny Chernobyl. The engineers exceed the safety limits of the reactors to understand what will happen, and the results of disregarding the limits were catastrophic. Another excellent example is in Gilgamesh. Gilgamesh and Enkidu overreach the periphery of the gods, and the result of their actions is the death of Enkidu. Consequences always follow pushing boundaries, but humans never stop exceeding perimeters.

    Today, Chernobyl is defined as an abandoned city in the northern Ukraine. Pripyat, the city founded in 1970 to house the workers for the nearby Chernobyl Nuclear Power Plant, is currently described as a ghost town. The population of Chernobyl in 2010 was around 500. Prior to the spring of 1986, the city was inhabited by about 14,000 residents. For $140-$160 U.S. dollars, SoloEast Travel offers guided tours of Chernobyl, but that price does not include the $80 charge for mandatory insurance. Plus, everyone who goes on the tour has to be tested for radiation before leaving the Zone of Alienation, the 19 mile area around the site. Long before the worst nuclear disaster in history, Chernobyl was a city. For more than 300 years after the nuclear fallout, the area will be contaminated.

    On March 28, 1979, at 4:00 A.M. Eastern time, the worst accident in commercial nuclear power history happened. It was a nice day in Dauphin county, Pennsylvania, and then it all happened. This accident was rated a 5 on a scale that only goes to 7. The scale is called International Nuclear Event Scale. It all started inside the secondary-system where the pilot-operated relief valve was stuck open releasing large amounts of nuclear reactor coolant. This horrific accident caused many scientists to worry about nuclear energy, as well as concerning scientists that it could be a danger to the world, so this caused many safety concerns among activists and the general public which resulted in in new regulations for the nuclear industry, and has been cited as a contributor to the decline of a new reactor construction program that was already underway in the 1970s. Even though this sounds like it should have caused many people to develop cancerous cells, epidemiological studies analyzing the rate of cancer in and around the area since the accident, determined there was a small statistically non-significant increase in the rate and thus no causal connection linking the accident with these cancers has been substantiated.

    Leading the disaster, Nuclear reactors require an element cooling with a particular finished objective to uproot the created warmth delivered by radioactive rote. Despite when not delivering power, reactors still make some warmth, which must be cleared with a specific end goal to forestall harm to the reactor center. Cooling is by and large refined through fluid stream, water in Chernobyl s case. The issue at the Chernobyl plant was that taking after an emergency shutdown of all force, diesel generators were expected to run the cooling pumps. These generators took around a minute to fulfill full speed, which was respected an inadmissible long time for the reactor to be without cooling. It was recommended that the rotational power of the backing off steam

    A large power reactor without containment [structure] could not be licensed here. Inopportunely, the Soviets couldn’t turn to America for help because they still had a grudge from the Cold War. More importantly, the absence of a containment structure is especially important. As pointed out by Rhodes article about Chernobyl, "Post-accident analyses indicate that if there had been U.S.-style containment, none of the radioactivity would have escaped, and there would have been no injuries or deaths" (Rhodes "Chernobyl", PBS).

    As planned by the TEPCO, in case of a disaster, the main power generators to the reactors are designed to shut down, consequently, shutting down the power that helps generate the coolant for the reactors. After the earth quake, the first step of the emergency procedure went well, however, the Tsumanin waves that followed the earth quake was about three times higher than the barrier built by TEPCO to prevent water from damaging equipments within the complex. The water dumped by the Tsumanin flooded the complex, including the basement that housed the backup diesel generators. With the generators demanded by the flooded the workers had no means of get water or coolant to cool the nuclear reactors, and as would be expected, the reactors began to overheat resulting in the nuclear meltdown of the Fukishima nuclear power plant reactors(”Inside Japan’s

    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).

    "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.

    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.

    One of the most significant environmentally damaging instances in history was the Chernobyl incident. In 1986, the Chernobyl Nuclear Plant in Ukraine exploded. It became one of the most significant disasters in the engineering community. There are different factors that contributed to the disaster. The personnel that were tasked with operating the plant were unqualified. The plant’s design was a complex one. The RBMK reactor was Soviet design, and the staff had not be acquainted with this particular design. As the operators performed tests on the reactor, they disabled the automatic shutdown mechanism. After the test, the attempt to shut down the reactor was unsuccessful as it was unstable. This is the immediate cause of the Chernobyl Accident. It later became the most significant nuclear disaster in the history of the

    Due to the 9.0 magnitude earthquake, a 15 metre tidal wave disabled the cooling system of three nuclear reactors and this caused a nuclear disaster which was rated 7 on the International Nuclear Events Scale. Nearby cities were endangered as the incident caused high radioactive releases that will last over 4 to 6 days. Approximately 100,000 people have been evacuated from their homes in order to protect them from the hazards of the radiation from the power plant. The power plants are being cooled to stabilise them as shown in Figure 7. Apart from cooling, the aim is to prevent the release of radioactive materials, especially the contaminated water that leaks from the three power plants.

  • Nuclear Power: Dirty, Dangerous and Expensive

    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.
