The Chernobyl accident is to date one of the worst nuclear accidents ever recorded with the Fukushima nuclear power plant, with the difference that the Chernobyl accident was terribly managed by the government. The disaster occurred on April 26, 1986, when a power outage was being simulated and a sudden increase in power in reactor 4 of the nuclear power plant caused overheating of the reactor core which caused detonation. hydrogen accumulated in its internal parts. This caused a considerable increase in the level of ionizing radiation across much of Europe. The Chernobyl accident was going to happen sooner or later. Operational standards, as well as design, containment-free construction, and quality control of nuclear power, were governed by Communist Party political criteria, not technical and economic criteria. Operators were not required to comply with strict safety standards and insure the factory against any type of risk by paying higher premiums because the factories were state-owned, unlike in Europe , in the United States and Japan where these safety standards are strictly controlled. On April 26, 1986, around 1:00 a.m., reactor number 4 at the Chernobyl nuclear power plant in Soviet Ukraine conducted a test in which a power outage was simulated, resulting in a sudden increase in power in the reactor 4 of the nuclear power plant. The power plant overheated the nuclear reactor core, which ultimately led to the hydrogen accumulated inside exploding. Basically, they wanted to experiment with it to see if the reactor's power turbines could produce enough electricity to cool the pumps in the event of an outage, until the diesel generators started up. The quantities of toxic radioactive materials were estimated to be around...... middle of paper ...... the commission pledged to help Ukraine with 65 million euros to buy electricity during the period of construction of new power plants (Gailliez & Chérié, 2010). It is the worst nuclear disaster the entire world has ever witnessed. The Chernobyl explosion and its harmful effects on public health and nature could have been avoided, but they were made possible thanks to a political system which cultivated secrecy and which did not see fit to give priority to development of restrictive safety methods to adapt to the operation of nuclear reactors. The long-term effects on humans affected by radiation from the disaster could not be accurately determined, even after more than twenty years. Many other negative consequences are expected for those affected and people living in areas where radiation is still present..
