On april 26 1986 when extremely hot nuclear fuel rods were lowered into cooling water an immense amount of steam was created which because of the reactors design flaws created more reactivity in the nuclear core of reactor number 4. The chernobyl disaster happened at 1 23 a m. On april 26 1986 operators in this control room of reactor 4 at the chernobyl nuclear power plant committed a fatal series of errors during a safety test triggering a reactor meltdown.
Analysis has shown that the corium was heated to at most 2 255 c and remained above 1 660 c for at least 4 days. The chernobyl corium is composed of the reactor uranium dioxide fuel its zircaloy cladding molten concrete and decomposed and molten serpentinite packed around the reactor as its thermal insulation. 1 commissioned in 1977.
Construction of the plant and the nearby city of pripyat to house workers and their families began in 1970 with reactor no. The nuclear power plant consisted of four rbmk 1000 reactors each capable of producing 1 000 megawatts mw of electric power 3 200 mw of thermal power and the four together produced about 10 of ukraine s electricity at the time of the disaster. A hospital in the nearby town of pripyat is overrun with radiation victims.
4 reactor of the chernobyl nuclear power plant. A large fire rages in the ruins of the no. It is considered the worst nuclear disaster in history and was caused by one of only two nuclear energy accidents rated at seven the maximum severity on the international.
4 reactor in the chernobyl nuclear power plant near the city of pripyat in the north of the ukrainian ssr. The chernobyl disaster was caused by a nuclear accident that occurred on saturday 26 april 1986 at the no. After the chernobyl accident some rbmk reactors were retrofitted with a partial containment structure in lieu of a full.
In the chernobyl accident the pressure rose to levels high enough to blow the top off the reactor breaking open the fuel channels in the process and starting a massive fire when air contacted the superheated graphite core. Today nobody knows what is inside the chernobyl reactor because it is conserved. After chernobyl reactor 4 explosion it was covered by the sarcophagus.
Nowadays the most sensitive spot of the exclusion zone is the chernobyl reactor 4 on which there was an accident in 1986.
Nuclear reactor core chernobyl reactor 4 today. In april 1986 reactor 4 of the wladimir iljitsch lenin atomic power station near the city of chernobyl experiences a catastrophic core meltdown. The radioactive lava that formed was named corium. What is inside chernobyl reactor number 4.
