The uncontained explosion of a nuclear reactor from the safety test had just impacted the world, and the resulting roof fires threatened the adjacent reactor. The incident occurred when the reactor crew attempted to carry out a safety test involving one of the plant's eight turbine-generators. The specific test the crew was conducting was to “determine how long turbines could spin and continue to supply power following loss of the primary electrical power supply.

Chernobyl Nuclear Accident Pripyat a city of 49,000 will soon become a city of none. Chernobyl a city of 14,000 will soon become a city of none. There common denominator, the Chernobyl Nuclear Accident of 1986. An accident that will lose a country $235-billion. An accident that will take the homes and lives once known to many.
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).
Here on April 26, 1986, one of the reactors of a nuclear power plant went out of control and caused the world's worst known reactor disaster to date. An experiment that was not properly supervised was conducted with the water-cooling system turned off. This led to the uncontrolled reaction, which in turn caused a steam explosion. The reactor's protective covering was blown off, and approximately 100 million curies of radionuclides were released into the atmosphere. Some of the radiation spread across northern Europe and into Great Britain.
The potential for human error causing a nuclear accident can be ascertained by considering the causes and effects of accidents that have already occurred. In 1952, at Chalk River’s Nuclear Reactor, four control pads were unintentionally removed, causing a partial meltdown of the reactor’s core. In 1957, a fire at the Windscale Pile No. 1 plant, just north of Liverpool, England, resulted in the contamination of 200 square miles of countryside when it was covered with radiation. In 1976, the core of the Lubmin nuclear plant in Greifswald, East Germany nearly melted down when safety systems failed during a fire.
Nuclear fallout is the residue and byproducts of a nuclear bomb explosion or in the case of Chernobyl, a nuclear accident. The Chernobyl accident occurred on April 26, 1986 at 1:23 a.m. just outside of Kiev, Ukraine. The nuclear reaction occurred because the reactor complex was made up of four reactors and the reactor design was flawed. Also, some of the operating personnel were improperly trained. A nuclear reaction is a change in the identity or the characteristics of an atomic nucleus.
According to United Nations Scientific Committee on the Effects of Atomic Radiation, or UNSCEAR, “The accident at the Chernobyl reactor happened during an experimental test of the electrical control system as the reactor was being shut down for routine maintenance. The operators, in violation of safety regulations, had switched off important control systems and allowed the reactor, which had design flaws, to reach unstable, low-power conditions. A sudden power surge caused a steam explosion that ruptured the reactor vessel, allowing further violent fuel-steam interactions that destroyed the reactor core and severely damaged the reactor building.” (United Nations Scientific Committee on the Effects of Atomic Radiation)Thus beg... ... middle of paper ... ...nal Atomic Energy Agency, n.d.

Study of the Nuclear Disaster of Chernobyl The worst accident in the history of this nuclear power generation occurred on the morning of April 26, 1986. It was at the Chernobyl (Ukraine) nuclear power station in the Soviet Union. At 1:32AM Lieutenant Colonel Leonid Telyatnikov received a telephone call and was told that there was a fire at the nuclear power plant. There were many reasons their plant had backfired. These reasons included human error and poor plant design due to the cold war.
Chernobyl was a result of a reactor design that was not properly operated. The nuclear release occurred while shutting off the power for turbine testing. The reactors were known to be unstable at low levels of power. Two explosions caused the graphite moderator to catch fire, burning for 9 days and releasing all the nuclear power plant's Xenon, half the iodine and cesium and 3-5% of all remaining radioactive material. The radioactive dust particle was carried by wind throughout bordering Ukrainian countries.
In the early morning of April 26th, 1986, two explosions tore through the Chernobyl nuclear power plant leaving behind nothing but rubble, nuclear fallout, and the infamy of what will probably long be called the worst nuclear disaster in history (World Nuclear Association, 2013). The cities of Chernobyl and Pripyat remain ghost towns due to extremely high levels of radiation still present 28 years after the explosion. The undeniable environmental effects of the blast couple with the severe health effects to earn the Chernobyl explosion its infamy. The Chernobyl power plant was built to satisfy a constant need for energy. The power plant was created to supply nearby cities—namely Pripyat and Chernobyl—with energy.
