Chernobyl
For another genius hour project I decided to do research on Chernobyl because it just seems interesting Where/When was Chernobyl Reactor 4 of Chernobyl exploded on April 26th, 1986 it happened in northern Ukraine just near the border of Belarus. How did reactor 4 explode That night on April 26th there supposed to run a safety test for reactor 4 but the reactor should have been at least been running over 700 plus megawatts to run the the safety test then then the number of megawatts drops to 0 they have to shut down the reactor, but the commander in the control insisted the kept working because they have to do the control test so his plan was to retract the control rods(which help control the reactor if some thing goes wrong thee bring the power down)which brung up the power level back up to 200 which still was not the required 700 megawatts but they still went ahead with the safety test. also the water level(used for cooling the reactor)...
