The Horrific Chernobyl Accident Essay

The electrical failure caused the operator to not know that the valve was still open, which led to cooling water pouring out of the valve and caused the reactor core to overheat. As a result of all of these things, the instruments that the operators read to know what was happening provided confusing information. The operators could not tell how much coolant was in the reactor core because they didn't

* The emergency energy supply was also shut down, meaning there was no additional energy to run the plant.

The disaster took place on April 1986, and was caused by inexperienced staff. When the power plant had to undergo a special test, to make sure that sufficient amount of cooling water would be supplied to the reactor in case of a power outage. However, the test had been delayed, because the national grid required the power output more than the expected time. Hence, the test was postponed after midnight where the night shift had to come. The night shift had little experience about such a test as most of them were electrical engineers rather than nuclear. On the other hand, the night shift had to perform the test before the grid needed the power again, otherwise they would have all been fined or fired. Consequently, lead to an unnecessary pressure on the personnel, which in turn increased the probability of making incorrect

The main reason that could be attributed to the cause of the Chernobyl accident was due to the irregular condition of the reactor on the day.

First, as mentioned above, failure to mention reactors design flaws led to distrust in the infrastructure of the Soviet Union. While many scientists and researchers such as Valeri Legasov had noticed that there were issues with the reactors design prior to the disaster, and mentioned so in personal journals, the discovery of their failure to speak up lead to the questioning of Soviet leadership [5]. Additionally, these issues became worse upon the discovery of KGB classified documents that discussed various issues with the construction of the Chernobyl plant between 1971 and 1988 [7]. These compounding issues identified flaws

The disaster had more of an effect on eastern Europe’s nuclear experimentation and use but “While no-one in the West was under any illusion about the safety of early Soviet reactor designs, some lessons learned have also been applicable to Western plants” (World Nuclear Association). Since the Chernobyl disaster was majorly caused by human error and under qualified scientists, to work with nuclear reactors today you need to be insanely qualified. Since the accident, Soviet-designed reactors’ safety has improved greatly, even in smaller ways. Automatic shutdown mechanisms now work faster, and other safety mechanisms have been sped up. Even new equipment has been installed such as automated inspection equipment. Several scientist and reporters have even said an accident like Chernobyl is virtually impossible with today’s technology (World Nuclear Association).

Kingdom. All children in both groups were born 8 years after the melt down. “

At 1:00 A.M. on 25 April, the command was given to start reducing power to the station. “This could not be done quickly because the xenon gas that came from the radioactive decay of uranium 135 absorbed neutrons. If not allowed to decay, which it did in a few hours, it could accelerate the decline in the reactor’s activity and close it down altogether.” (Read p.59) Twelve hours after the start of the power reduction, the reactor had reached half-power, and generator number 7 was switched off. The number 8 generator would be next, but there was a slight risk that the decrease in water supply to the reactor or the start up of the auxiliary generator would signal an emergency to the system sensors that would automatically start the emergency core cooling system. If this happened, the reactor would be flooded and it would be closed down. Dyatlov had the emergency system disconnected so that the test could continue uninterrupted. After the this system was disconnected, the test was ready to proceed, which was to reduce power in the number 8 generator and take it off line, all the while keeping the reactor on low power. As the order was given, a call came in from the power grid dispatcher in Kiev saying that the power that the number 8 generator produced was needed until 11 P.M., which meant that the test had to be postponed. (Read, 1993)

(MP1) What Chernobyl plant represented in 1980s and who is responsible for such a massive disaster

There have been lots of nuclear accident around the world. One of the accident that had a major impact on the world was the Chernobyl disaster. The disaster took place on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine. The disaster was caused by a reaction explosion induced by design faults and staff application errors. The accident took place in the course of scheduled tests to check the power supply mode in the event of external sources loss. Even after 10 days, explosions and ejections of radioactive substances continued. The release of radiation and radioactive substance polluted the places within 30 km of Chernobyl, and those areas have been closed for a long period of

The personnel violated the safety protocols and the safety construction codes; as a result, the pressure of the reactor was suddenly uncontrolled. This explosion was equivalent radiation of 400 Hiroshima bombs. In Prypiat the nearest city was in a small alert, citizens of Pripyat were unnoticed of what was really occurring at the time. A few hours later a military command was sent to test the plant radioactive measure, they estimate 2.8k roentgen which was equivalent for human to die in 15 minutes. 36 hours later 400,000 people were forced to leave their home forever many of them were unaware of the matter. The hardest hit is an area of almost 1,100 square miles around the Chernobyl reactor. The full evacuation of Chernobyl and a radius of 30 miles wasn't done before May 2 by then more than 1000 were affected by severe radiation. A massive decontamination process was initiated by 600 thousand persons called ‘liquidators’. The group of liquidators was composed mainly of firefighters, scientists, workers and specialists of the nuclear industry ground and air troops prepared for the atomic war and engineers of mines,

Early in the morning of April 27, 1986, the world experienced its largest nuclear disaster ever (Gould 40). While violating safety protocol during a test, Reactor 4 at the Chernobyl power plant was placed in a severely unstable state, and in a matter of seconds the reactor output shot up to 120 times the rated output (Flavin 8). The resulting steam explosion tossed aside the reactor’s 1,000 ton concrete covering and released radioactive particles up to one and a half miles into the sky (Gould 38). The explosion and resulting fires caused 31 immediate deaths and over a thousand injuries, including radiation poisoning (Flavin 5). After the

The main reason for the mishap is by now well recognized (Petryna 1). However, initially the Chernobyl catastrophe baffled the minds of people in the 20th century and definitely left the people of Ukraine disordered while living in anxiety. Now, without question, the public knows that the accident at Chernobyl was the result of a disastrous combination of ignorance from the Ukrainians and complacency from the Soviets in control of Ukraine at the time. As according to American physicist and Nobel laureate Hans Bethe, “…the Chernobyl disaster tells us about the deficiencies of the Soviet political and administrative system rather than about problems with nuclear power." The immediate basis of the Chernobyl accident was a mismanaged electrical-engineering experiment (Rhodes "Chernobyl", PBS). While, the indirect source of the calamity was an industrial malfunction of a Soviet made nuclear-based machine. Ironically, the Chernobyl accident occurred during a test run, which was conducted to improve plant safety. This accident proved once more what experienced control engineers have all learned: that a process must be understood before it can be controlled. (Liptak “Control Global”). Engineers with no familiarity of reactor physics were interested to see if they could draw electricity from the turbine generator of the Number 4 reactor unit to run water pumps during an emergency, when the turbine was no longer being driven by the reactor but was

for the next time they would be able to conduct would be in one year

In the modern society, energy is considered one of our most valuable resources. Humanity has managed to tap several sources of energy and utilize it for their daily activities. Almost everything in the society is dependent on energy; otherwise, humanity would cease to exist. The sources of energy vary from firewood, solar energy, geothermal energy and nuclear energy. The sources vary depending on the amount of energy that can be harnessed. Nuclear energy is a controversial subject when it comes to energy matters. Theorists argue that the world’s sources of energy are being depleted at such high rates, that the future will not favor humanity. Richard Watson establishes this ethical argument in his work known as Anti-Anthropocentric Ethics: he argues that any ethics should be based on the survival of humanity (Watson 245). Therefore, an inquiry that should be made in line with energy and ethics should consider the question; is modernization worth killing humanity? Nuclear power sources provide such high energy that can power industries and sustain industrial processes for longer times. The problem with the nuclear power energy is the danger it poses to the society and humanity as a whole (Ingram 37). The Chernobyl nuclear power plant in Russia is a good example relative to the effects of nuclear power and the environment. This essay seeks to analyze and evaluate the ethical issues raised by the Chernobyl nuclear plant as source of energy
