Detailed explanation-1: -1. What caused the Chernobyl accident? On April 26, 1986, the Number Four RBMK reactor at the nuclear power plant at Chernobyl, Ukraine, went out of control during a test at low-power, leading to an explosion and fire that demolished the reactor building and released large amounts of radiation into the atmosphere.
Detailed explanation-2: -April 26, 1986, 1:23:58 a.m. The first explosion, to be quickly followed by at least one more, blows the 1, 000-ton roof right off the reactor and shoots a fireball high into the night sky.
Detailed explanation-3: -The title refers to the exact moment (1:23:40 a.m.) the emergency shutdown of the reactor was initiated, ultimately causing its explosion seconds later at about 1:23:45 a.m., or 12345.
