Fukushima Nuclear Accident

Introduction

When analyzing the causes of the accident we can deduce that none of the causes caused by the explosions and therefore the release of radioactive material and environmental pollution were due to human errors, as the Chernobil nuclear accident can be verified. Natural disasters are not something that can be prevented, much less control. 

The earthquake caused the power cut, I cause that the refrigerant pumps stop working. For these cases the reactors were equipped with emergency generators that worked with diesel to continue using these pumps, but then the tsunami came with large waves, waves of up to 14 meters were measured. The reactors had containment walls that only mediate 5.7 meters, so it was exceeded by sea water, damaging emergency generators and causing the refrigerant pumps to stop working completely. 

Developing

Fukushima’s nuclear accident occurred on March 11, 2011, at the nuclear plant of this town. This accident occurred as a result one of the largest earthquakes registered in the world, of magnitude 9.0 on the Richter scale, which also caused the Japanese coasts to be whipped by a tsunami with waves up to 14 meters. When the earthquake took. 

Because the electrical failures, all the systems went out so that the generators that worked with diesel were automatically lit, those that fulfilled the function of activating the pumps that circulated the refrigerant to the nuclei of the reactors.

Wait! Fukushima Nuclear Accident paper is just an example!

46 minutes after the earthquake, the tsunami arrived at the coast, with large waves that exceeded the containment wall of the nuclear plant, flooding the lower part of the reactors 1, 2, 3 and 4, which destroyed the generatorsof emergency.

 When these elements were destroyed by seawater, I caused a lack of refrigerants, which resulted in three nuclear mergers and three hydrogen explosions, between March 12 and 15, in reactors 1, 2 and 3 I released aA large amount of radioactive material. Due to the great radioactivity released by these explosions, the nuclear and industrial safety agency (NISA) declared that the accident was level 7 on the International Scale of Nuclear Accidents (INES), a similar level reached by the nuclear accident ofChernobyl in 1986. In the following days of the nuclear accident, the government decided to begin to evacuate the population within a radius of 20 km, which led to evacuate a total of 154.000 inhabitants. The environment was contaminated by large levels of radiation and even the Pacific Ocean.

This increase in the heat of the core of the reactors, producing nuclear mergers and large explosions, which released the radioactive material. The technicians of the plant did not have much more to do, since the protocols followed the mechanisms to avoid any catastrophe were disabled by the previous causes. In the same way we can say that the catastrophe was lower because at the time of the accident only three reactors of the six were operating, since three were in maintenance. This increase in the heat of the core of the reactors, producing nuclear mergers and large explosions, which released the radioactive material.

The immediate consequences of the nuclear accident was the great propagation of radioactive material released in the Pacific Ocean and on Earth north of Fukushima due to the winds and liquids that were leaked directly to the sea both by the entrance of the sea by the tsunami andThe water launched in the attempt to cool the nuclei. In the case of the population, the absorbed doses were not very large, so in the short term it had no consequences. 

In the long term there has been an increase in diseases such as cancer, leukemia, etc. In animals, certain deformities have been manifested in butterflies that inhabit the area affected by radiation. Although manifestations of diseases are not massive, in the same way the established government, prevention reforms in drinking water and food.

In the workers who were present, no major consequences were seen, since the absorbed doses were under the permitted limits, although the government does recognize the death of a worker due to lung cancer due to radiation after the explosion.

conclusion

When heat increased due to systematic failures, the nuclei was attempted externally. When expanding the radioactive elements released by the explosions, the protection radio measure that was taken with the population was to evacuate a radius of 20 km. The measures used today are to have closed the area where radiation is still at high levels. The ocean is maintained control and under evaluation where radioactive material and the soil contaminated by environmental radiation were released. Ways are also used for reactors to continue emitting radiation, with cooling systems that do not release the materials still active.
