The Chernobyl Nuclear Reactor Meltdown Essay

realize that the plant was having an accident with the coolant level. The tubes holding the nuclear fuel began to melt since they became over heated which also caused fuel pellets to melt. Even though this was the most dangerous kind of nuclear accident, the radiation did not reach outside of the containment building nor did it release out into the environment. There were no immediate injuries or deaths reported from the raditation to the faculty workers.

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).

On April 26, 1986, a nuclear reactor at the Chernobyl Nuclear Power Plant experienced a catastrophic meltdown that emitted radioactive material into the atmosphere, killing 31 people.

The morning of April 26, 1986 started just like all other mornings in Chernobyl, with just one exception, there was an emergency systems test underway at the near-by nuclear power station. This test was unauthorized, none the less, it was designed to ensure cooling water for the reactor could still be controlled with little or no power to the station. The cold war was in full swing, and Russia was still poised to go to war with the United States at any moment. It was due to this “distrust” that the test was being run that morning. The head nuclear scientist on shift, Anatoli Dyatlov, was from the “old school” and thought that he alone could control the whole reactor process, and he also thought he knew more

On Saturday, 26 April 1986 a reactor at the Chernobyl Power Plant near Pripyat, Russia has a sudden power surge which caused mass damage. The Power Plant tried for immediate

For some reason, the center control rod, possibly for maintenance purposes, was manually lifted approximately 50 cm (Stacy, 2000, 141). This caused there to be an instant, or prompt, criticality which caused the reactor to blow up (Stacy, 2000, 141). The reason for this appears to be that the reactor activated due to the reaction caused by the influx of water, a moderator, into the system. The reaction rapidly heated the moderator and the cooling water to steam which expanded in the small containment vessel and caused the reactor pressure lid to blow off of the vessel (Stacy, 2000, 141). Two of the three men, who were working inside the reactor compartment, apparently died instantly from the explosion. The other

People and animals were affected badly some died from the chernobyl explosion. Many died from it because it was so bad,

* The electrical supply to the reactors water pumps was reduced as a result of the experiment, reducing the amount of cooling water passing through the reactor.

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

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 Chernobyl accident was a disastrous nuclear event that happened on 26th April 1986 at the Chernobyl Nuclear Power Plant in Ukraine. The Chernobyl disaster is classified as a level 7 event according to the International Nuclear Event Scale (only two events have been classified this high in the past) and has caused damages that consist of the cost of 500,000 workers and 18 billion rubles, 31 deaths according to the Soviet casualty count (this is still being disputed) and between 4000-27000 affected future deaths due to radiation exposure [G1].

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

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 causes of the accident was quite complex. In brief, it began with a closed bypass valve, which stopped the water flowing to the secondary main feed water pumps, once the steam generators could not receive water, they stopped and the reactor emergently shutdown. Control rods were inserted into the
