In Ukraine, about 20 km south of the border with Belarus, is the Chernobyl nuclear power plant. On April 25, 1986, the Chernobyl nuclear power plant collapsed, sending blasts of electricity through the control room. The radioactivity was ninety times greater than that of the Hiroshima and Nagasaki bombs on the nearby villa. The Chernobyl accident destroyed the fourth reactor and killed more than 30 workers and firefighters. Afterwards, due to his injuries, one person was killed immediately and the second died in hospital. Acute radiation syndrome (ARS) occurred in more than 237 people on site and involved in the cleanup. It was subsequently confirmed in more than 134 cases. A few weeks after the accident 28 people died from ARS. Although a large area of ​​childhood thyroid cancers has been affected by the incident. This incident occurred with more than one cause and several added contributors. The accident occurred during tests of the RMBK reactor. In the reactor count there was a huge reaction that caused explosions and a huge fireball that blew off the reactor's heavy concrete and steel lid. Design flaw in the RBMK reactor, violation of procedures and communication breakdown are the causes of the accident. An RBMK reactor is a high-pressure water reactor that uses a graphite moderator and a water cooling system. On April 25, 1986, the RBMK reactor 4 of the Chernobyl nuclear power plant was supposed to temporarily shut down for routine maintenance. The Chernobyl 4 reactor crew began preparing for a test to determine how long the turbines would spin and provide power to the main circulation pumps and main electrical supply. This test was sent to Chernobyl last year after the accident. However, the bit... in the center of the map... a very distant area that could cover a few countries. Many people's lives could be in danger if professional engineering fails to find a result for diastasis. Conclusion At the end of this essay, professional engineers have a very important job in our life. The fact that the Chernobyl nuclear power plant may still be operating to this day. It would also be the largest and most powerful station that would produce the most energy. On the other hand, the station's engineering could have saved many lives by working together before disaster struck. Throughout the day, we can see that disaster could occur at any time or due to any mistake which leads to many bad effects. Due to the result of the nuclear test and the ignorance of the light in the laboratory, it was engineering's fault to be able to keep the station running and their work on the station.
