On April 26th 1986, a catastrophic nuclear accident occurred at the Chernobyl power plant. This power plant consisted of four Nuclear reactors of type RBMK-1000. “The Chernobyl complex consists of four reactors constructed between 1977 and 1983 (No. 1 in 1977, No. 2 in 1978, No. 3 in 1981, and No. 4 in 1983)” (Chernobyl- accident – Ukraine: 1986). The reactors were produced by the Soviet Union. At Chernobyl, reactors one and two were first generation and reactors three and four were the second generation Those reactors were used to produce electricity. Each reactor produced 1,000 megawatts of electric power. They also produced 3.2 GW of thermal power. The four reactors supplied Ukraine with about 10% of its power at the time of the accident. The explosion released large amount of radioactive particles in the atmosphere. Along with the Radioactive particles, there was an explosion and fire. The main question here is what caused the explosion. Reactor four suffered an enormous power increase which lead its core to explode. The explosion released radioactive fuel which ignited the combustible graphite moderator. The graphite moderator increased the emission of radioactive particles. The most shocking fact about this disaster is that it occurred during a scheduled test to show the safety emergency core cooling. The steam turbines used water as a coolant. During a normal operation, about 7% of the power doesn’t come from fission but comes from the decay heat. This heat…
