Detailed explanation-1: -The Chernobyl Power Complex, lying about 130 km north of Kiev, Ukraine, and about 20 km south of the border with Belarus, consisted of four nuclear reactors of the RBMK-1000 design (see information page on RBMK Reactors).

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. A blackout roils the plant as the air fills with dust and graphite chunks, and radiation begins spewing out.

Detailed explanation-3: -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-4: -Up to 30 percent of Chernobyl’s 190 metric tons of uranium was now in the atmosphere, and the Soviet Union eventually evacuated 335, 000 people, establishing a 19-mile-wide “exclusion zone” around the reactor. At least 28 people initially died as a result of the accident, while more than 100 were injured.
