A second, more powerful explosion occurred about two or three seconds after the first; this explosion dispersed the damaged core and effectively terminated the nuclear chain reaction. This explosion also compromised more of the reactor containment vessel and ejected hot lumps of graphite moderator.
The reactor’s emergency safety systems had been turned off. The Chernobyl nuclear power station in present-day Ukraine consisted of four 1,000-megawatt reactors, plus two additional reactors that were under construction.
Chernobyl Timeline. April 25, 1986 1:06 am Normal operation: reactor was at full power. Steam power was directed to both turbines of the power generators. The purpose of the test was to determine if one of the turbines could supply power to feedwater pumps until standby diesel generators came on line in the case of a local power failure.
February 1986: A Soviet official is quoted saying that the odds of a nuclear meltdown are “ one in 10,000 years .” By this time, the Chernobyl site contains four 1,000-megawatt reactors, plus two additional reactors that are under construction.
