Essay Examples on Chernobyl Paper 1st Essay Sample on Chernobyl The Chernobyl Accident negatively affected not only the people of the Ukraine and surrounding countries; it also affected the economy, health and the environment. On April 26th, 1986, something horribly went wrong with reactor four at the power plant in Chernobyl.This accident has so far been the worst one in the worlds history of power plants.This accident was caused partly by the operator and partly by faults in the reactor construction.There was an experiment that was being done in order to investigate the possibility of making electricity from the residual energy in the turbo-generators, after the supply of steam was shut off.The experiment was poorly planned, and was led by an electrical engineer who wasnt familiar with the reactor facility.The operators broke six very important safety rules, and all shutdown systems were off-line.The emergency core cooling systems for the reactor had also been off-line.The experiment could only be completed while the reactor was low in power, something that led the operators to believe mistakenly that they were carrying out a safe operation.Just after 1:00am on April 26th, the reactor was operating at a low power level and all control rods were withdrawn from the reactor core.The power output had been so low, the operators thought that they could control it manually.They overrode the automatic control system so that the reactor wouldnt come to a halt.The power increase was slow atfirst, quickly increasing to a power doubling itself in less than one second.The water in the core exploded into steam. The fuel elements were destroyed by the blast, which also caused the roof of the reactor to blow away.That gave fresh air access to the reactor which fed the explosion.The fire lasted for several days releasing dangerous chemicals into the atmosphere. 2nd Essay Sample on Chernobyl Good evening comrades. All of you know that there has been an incredible misfortune – that accident at the Chernobyl Nuclear Plant. It has painfully affected the soviet people, and shocked the international community. For thefirst time, we confront the real force of nuclear energy, out of control (LaMotte 1). These very words were delivered by Soviet President Mikhail Gorbachev following the Chernobyl catastrophe. Chernobyl was a nuclear power plant located in the former Soviet Union. Eighty miles north of Kiev, the reactor four exploded on April 26, 1986. The disaster started on April 25, 1986, as a test was put underway. The test was to determine how long the reactors turbines would spin and supply power following a loss of main electric power supply. Operational error caused the test to go bad. The power fell way below safe levels. To regain power, control rods were removed. The flow of feed water was reduced as well to maintain steam pressure. Despite efforts, the pumps p owered by slowing turbines provided less and less cooling to the reactor. A dramatic power surge followed. The quick increase in temperature caused the fuel elements to rupture. The fuel particles reacted with the water to create an explosion of steam. A fireball blew off the reactors steel and concrete lid. A second explosion came not long after thefirst sending fragments of burning feul and graphite into the atmosphere. The graphite moderator had burst into flames. It burnt for nine days causing the release of most of the radioactivity. In fact 5% of the reactor core was thrown into the atmosphere. Following the disaster a total of over 600,000 people were involved in the recovery and cleanup which lasted through 1987. Thirty-one people were killed while 45,000 residents living within a 10km radius of the plant were evacuated. Later another 116,000 others were moved.
