The Pros And Cons Of Fukushima Daiichi

This caused reactors 1 through 3 to go into a meltdown and it created a situation where Japan was on the brink of a major environmental disaster. To fully understand the different events there will be a focus on: factors that caused the meltdown, why this did not impact the other three reactors, the consequences, who is responsible and how these incidents can be prevented in the future. Together, these elements will highlight the underlying effects of this disaster and its impact on the region. ("Fukushima Accident")

It’s clear that a Nuclear power plant such as the Fukushima Daiichi can be classified as an HRO if not an Ultra HRO, where an accident has an effect that, even in the technologically advanced Japan, can threaten the lives of millions and negatively impact their health for many years.

“An atom is the fundamental block of all matter, atoms are composed of smaller subatomic particles neutrons, [Neutral], protons [Positive (+)] and electrons [negative (-)]. Nuclear energy is the energy formed from the nucleus of an atom through different methods as fission (which is the way in which an atom is split into smaller subatomic particles by hitting its nucleus with a neutron) and fusion (which is the process in which new heavier atoms and large amounts of energy are produced by bonding atoms together). (Nuclear Energy).Nuclear energy has various pros and cons, some of its advantages are that it reduces global warming as a result of decreasing greenhouse gases emission and CO92 production. While, its main disadvantage, is that the

The Fukushima disaster was caused by an earthquake and its following tsunami which caused a failure in the backup systems (World Nuclear Association, 2016). The tsunami knocked out the generators that powered the cooldown processes for three of the Fukushima power plants which caused the radiation leaks and other complications. Consequentially, the disaster was initially classified as a level 5 on the INES scale. Further investigation after the disaster was under control changed it to a level 7 disaster, the highest level on the INES scale. The estimated radioactive releases were about one tenth of Chernobyl, the worst nuclear disaster in history.

When an 9.0 magnitude earthquake rocked Japan on March 11th, 2011, it was the first of a series of horrific events that Japan would be forced to endure. Many homes, families, properties, and belongings were lost on that day. And when the tsunami rolled over the island, many believed that it was over for them. Not only had people’s lives been put in disarray and desolation, but there had not even been simple necessities available. Food. Water. Communications. And electricity. When the Fukushima Daiichi nuclear plant had been hit by the earthquake and tsunami, the reactors were shut down and so was the electricity. Over the course of months the reactors suffered, extreme heat, fires, hydrogen explosions, and radiation exposures. At the time,

Recently, the deserted Fukushima Daiichi Nuclear Power Plant has been emanating an alarming amount of radiation. Kyodo of Japan Times reported that the radiation reading has reached its highest level since its emergence in March 2011 (Kyodo, 2017). As a result, there is a greater presence of air and water pollution in Fukushima that could easily spread to surrounding areas. Therefore, it seems appropriate that in an interview with the Washington Post, radio-ecology expert Tom Hinton stated Fukushima is “an area that is among the most radioactively contaminated in the world” (as cited in Andrews, 2016). This resurgence has generated conspiracy theories, false maps and, interestingly, little news coverage. While many across different continents

Being a supporter of nuclear power in today’s society could be potentially risky. So conveys author William Tucker who believes there is no other alternative, even after the Fukushima disaster (228). Tucker uses a plethora of examples and statistics to demonstrate how nuclear power could be the best alternative; moreover, he doesn’t specify which energy technology is most dangerous, but states that they all are in different ways. All alternatives have risks that determine how harmful they can be; however, it is up to the people to decide how much they are willing to risk. Progressing on from the risks, Tucker claims that we need nuclear power “if we are going to maintain our standard of living” (228). As others try to disprove this statement,

The current energy sources we consume in the US are in need of a change. Dependence on the fossil fuels of oil and coal are hazardous for two important reasons: their undesirable impact on the environment and it has created the economic boom in the US. There is an agreement between the public and experts that nuclear fission is not the answer. The catastrophic meltdown of the Fukushima nuclear plant after an earthquake in Japan provides the proof. The introduction of horizontal drilling by the gas industry combined with successful development techniques of hydraulic fracturing has showcased as a solution to solve these problems altogether. We now gain access to the 100 years ' worth of energy in the form of natural gas underneath the

Despite citizens opposed nuclear power plants, the government positions nuclear power plants as "important baseload power supplies" and shows the posture to utilize it as well as before nuclear accident six years ago, government decided to "reduce it as much as possible". In other words, people's resistance failed. The government wants to supply stable electricity at low cost, and Japan is an island country with few resources, and if there is no nuclear power will be insufficient when it is emergency. In addition, from the dangers of nuclear accident occurrence, citizens raise demonstrations or requests compensation. There are many people who oppose restarting in Japan because there are many people who think that safety is more important than

On the 11th of March, 2011, a 9.0-magnitude earthquake struck near the eastern coast of Japan. Emergency shutdown procedures went into effect when the earthquake was spotted, but this was not the main cause of the destruction of the nuclear reactor. The first line of defense was to immediately stop the nuclear fission within the reactor by inserting neutron absorbing rods to stop the reaction. After the engineers successfully stopped the nuclear fission reaction, immense heat and pressure was still prominent and needed to be relieved as soon as possible. Fresh water was brought in and dumped onto the rods but a tsunami inevitably followed as soon as the earthquake was felt as the source of the natural disaster was on the ocean floor. The tidal wave severely damaged the power supply system that was meant to maintain the flow was cold water. On March 12, 2011, diesel powered generators were initiated in an attempt to alleviate the failure of the generators that were powering the entire plant. Unfortunately, the diesel powered generator was insufficient enough to cool the large reactor as the heat building up within was accumulating in large amounts; more than what nuclear engineers originally presumed. Water continued to evaporate causing a hydrogen gas to form when the fuel rods underwent a chemical reaction with the steam. Hydrogen gas is an important element to take into consideration as too much of this element can cause an explosion within the reactor. Workers quickly

Then the question came up that how did the natural disaster occurred, man-made hazards with high technology, and heighten the risk to environmental health. Acceding to the Implications of the Fukushima Nuclear Disaster: Man-Made Hazards, Vulnerability Factors, and Risk to Environmental Health, first of all, the earthquake and tsunami exceeded estimations. Many international sources suggested that secondary technological is needed in order to estimate that incident. This Fukushima incident involved the first ever reactor core melt occurred by earthquake and tsunami. Since Fukushima is north part of japan by the ocean, many fish market and dealer were there, however, people started buying from them because of radiation. Radiation makes affect not only human. It is also effect environment and natural animals such as fishes. If you eat affected fish you will also get effect of radiation. The Fukushima disaster became a public debate emerge over the future desirability of nuclear power in Japan. Despite the growing anti-nuclear sentiment and concerns about the environmental risks of nuclear power, we contend that the continuing power of vested

Fukushima represents a catastrophe that had world wide implications for the nuclear power sector. On March 11, 2011, following a major earthquake, a 15 m tsunami hit the coast of Japan. This natural disaster caused a great deal of damage to the surrounding areas, but had a particularly dangerous effect on the Fukushima Daiichi Nuclear Power Station. In response to the initial earthquake, the operating units at Fukushima were automatically shutdown (Hindmarsh, 5). The 15 m tsunami, which hit the plant, flooded it under several meters of water. This combined caused the entire plant to suffer a complete power blackout. It was not believed that the plant would lose all power, nor that a tsunami of such size could occur (Hindmarsh 28). Resulting from the loss of power, existing cooling functions for the reactors were shut down also and as a result, fuel in the core was damaged, and radioactive material was released into the environment (Hindmarsh 12). Charles Perrow's Normal Accident Theory (NAT) proposes "a framework for characterizing complex technological systems such as air traffic, marine traffic, chemical plants, dams, and especially nuclear power plants according to their riskiness" (“Normal Accidents” 5). Perrow suggests that systems that are highly complex and tightly coupled create the environment for ‘normal accidents’ to occur; that is, accidents that are inevitable (“Normal Accidents” 88-89).

Fukushima catastrophic is a warning to the world about the hazards of nuclear power and contained lessons for the other governments who plan new generation of nuclear power stations. First lesson is the full disclosure on potential risks and share creditable information with the public. Furthermore,

The Fukushima was caused by a 15-meter tsunami that crumbled and destroyed the power supply of three Fukushima reactors. Ineffect to the crumbling of the three Fukushima reactors, more than 100,000 people had to be evacuated from their homes in Japan. Government officials were nervous about people returning to their homes due to the cause of possible radioactive materials being released into

On March 11th, 2011, the northern section of Japan was hit by a 9.0 magnitude earthquake, followed by a 15 meter tsunami, causing the death of over 15000 people. (Spacey) Even though the earthquake and the tsunami caused a tremendous amount of deaths in the northern region of Japan, the meltdown of the Fukushima nuclear power plant caused a severe damage to northern Japan’s ecosystem that people still cannot go back to their homes; despite it is 4 years after the disaster. After the earthquake, the tsunami destroyed the power supply used by Fukushima’s three nuclear power stations, causing severe levels of meltdown to be occurred inside the reactors in the timespan of 3 days. It was not until 2 weeks after the tragedy, when the reactors were finally stabilized, and took several months to approach what is called a “cold shutdown condition”, in which the fission in the reactors are completely stopped.(Fukushima A)
