In this project I shall be talking about Chernobyl. Chernobyl is a city that experienced a nuclear meltdown back in 1986, the meltdown had caused the entire city area to be uninhabitable due to the risk to human health and the damage to agriculture the radiation had caused. Unit 4 of the Chernobyl station was put into operation in December 1983. The plant was to be shut down for a medium repair on April 25th 1986. The Chernobyl disaster was a unique event and the only accident in the history of commercial nuclear power where radiation-related fatalities occurred Many people that lived in Chernobyl had suffered illnesses due to the exposure to radiation. Chernobyl is considered one of the biggest engineering disasters to date due to its severity.…show more content…
The city was populated with around 50,000 people, which mainly consisted of workers in the power plant itself. The soviet designed plant uses a system that we use today for nuclear power. The nuclear plant much lie coal plants heat up a container of water to create stem which then powers a turbine to create electrical energy. Due to the vast amounts of heat energy created by a reactor the reaction must be contained, they do this by using separation rods. The separation rods move up and down in the uranium to slow down the chain reaction in the uranium. This happens by blocking different sections of the container holding the uranium for a short space of time then opening again to let the neutrons pass to continue the process and gain as much heat energy as possible from the…show more content…
The main reason for the meltdown in the Chernobyl plant was underqualified personnel, unable to perform the safety tests in a safe manner. The test that was taking place was to test the systems safety features, one of the features put to the test was that when with the resulting loss of offsite power and the isolation of the steam supply to the turbine, that the rotating inertia of the turbine generator would be enough to generate electricity to power certain safety systems before a diesel generator was able to power on and take the electrical load. During this test the system had shut down as one of the safety systems had kicked in preventing the power plant from entering an unstable state. The operator had then overridden the safety system for the power plant to continue running for the safety checks. Another safety system then kicked in shutting the reactor down again. Unfortunately, the operator had overridden every safety shutdown system on the reactor causing the reactor to be in an unstable and vulnerable state. However even with the power plant in a very vulnerable state the operator had continued on with his
