it was april 26, 1986,

it occured because of an attempt was made to insert the control rods into the reactor core quickly, after having taken them out, and an effect was the the core structure of graphite blocks

had changed and would not allow the control rods to push into the holes of the blocks, leading to rapid heat production,and the explosion.
