At eleven o'clock at night on April 25, the control rods which are used to regulate the fission process in a nuclear reactor were lowered. The fission process being the process used to absorb nuetrons thus slowing the initial chain reaction. When the engineers lowered the rods it reduced the output of the reactor by 20% of the normal output required for a test.
By one o'clock in the morning of April 26, the power of the reactor was only about 7%, so the engineers raised more rods to raise the power. The engineers disabled the reactor's automatic shutdown system to allow the reactor to work under low power conditions.
Control rods were again raised by engineers to increase power. By one twenty-three on the morning of April 26, the power reached 12% and the decision was made to carry on with the experiment. Only after a few seconds though, the power levels suddenly surged to dangerous levels.
This caused the reactor to overheat the water in the cooling system started to steam. At this point there were only six control rods remained in the reactor core, the minimum safe operating number was thirty.
At one twenty-four on the morning of April 26, the first two explosions occurred and caused the reactor's roof to blow off and the content to erupt out. The roof being blown off caused air to get into the reactor and ignite the carbon monoxide gas causing a reactor fire. The reactor fire burned for nine days.
1:23 A.M. April 26th - Rods were raised again and power levels surged. Control rods were removed from the reactor but, the reactor began to overheat and the emergency button was pressed causing control rods to enter the core. Which caused pressure to go into the core.
1:24 A.M. April 26th - Two explosions happen causing the roof to blow off and radioactive gases were released into the air.
Modern Times April 26th – There are many health and environmental damages still around from the explosion 21 years ago.
Since I could not find any information on the scientists of Chernobyl. My Important people will be the firefighters that helped to put out the fires that raged, the doctors that helped to treat the citizens’ and workers’ cancer, and the scientists that helped to discover more about Chernobyl.
