Unformatted text preview: Sheet1 Page 1 Chernobyl : The Chernobyl disaster on April 26, 1986 is described as one of the most frightening environmental disasters in the worl up of four graphite reactors, which were the most modern Soviet reactors of the RBMK-type. Two more of these reactors construction at the station. Chernobyl was an obscure town in north central Ukraine (former Soviet Union) on the Pripyiat border. Immediately its name was joined to the Nuclear Power Plant located twenty-five kilometers upstream. The plant is kilometers northwest of the city. It is not only the radioactive mess left that strikes fear. Nineteen similar stations are still ru the former Soviet Union nor its republics can afford to shut them down. The world first learned of this accident from Swed radiation levels were noticed at one of their own nuclear facilities. At 1:23 am technicians at the Chernobyl Plant took som will impact the course of Soviet events without exaggeration. Human error is what basically caused the disaster. These op slowly allowed power in the reactor to fall to low levels as part of a controlled experiment gone wrong. The purpose of the dynamics of the RMBK reactor with limited power flow. Twelve hours after power reduction was initiated, power reached 5 turbine was needed to take in the decreased amount of steam, so no. 2 was turned off. Power was then reduced to 30 pe operators made a mistake. Instead of keeping power at 30 percent, he forgot to reset a controller, which caused the powe percent. Now water was filling the core, and xenon (a neutron absorbing gas) built up in the reactor. The power was too lo water added to the reactor is heated by the nuclear reaction and turned into steam to turn the turbines of the generator. T reactor up to 7% power by removing all but 6 of the control rods. This was a violation of procedure and the reactor was ne such low power. This type of reactor is very unstable when filled with water. The operator was not successful in getting thsuch low power....
