A test was conceived and conducted that attempted to solve the problem of providing adequate cooling following a shutdown. The problem was that the emergency generators took too long to come up to full power, so the concept was that the still spinning turbine, on its deceleration, would provide enough electrical power to run the emergency core cooling system.
Several designs were attempted and failed. During the last fatal attempt, there was a loss of coolant accident (LOCA) coupled with a super prompt criticality that caused the core to explode. Since the core was moderated with graphite, and graphite is flammable, the debris and nuclear materials continued to burn. Since there was no primary or secondary containment, the explosion blasted the core all over the landscape.
It is believed that a sequence of several errors led to the accident, but most of the people on site died as a result of the accident, so there is not a lot of certainty as to what exactly transpired.
For more information, including a detailed account of the accident, some of which has been pieced together by analysis, please see the Related Link below.
Note: The explosion was a Steam explosion in response to the LOCA, not a Nuclear explosion.

What famous disaster happened at Chernobyl in Russia?
There was no famous disaster (or anything else) at Chernobyl in Russia as there is no such place. However for the disaster that occurred in Chernobyl in the Ukraine, please see the related question.
What caused the sky over Chernobyl to glow during the nuclear disaster?
During the Chernobyl nuclear disaster, the sky glowed due to a phenomenon called ionizing radiation, which caused the air to become charged and emit a blue light.
Was the chernobyl disaster during the war with the US and Iraq?
The Chernobyl disaster took place in 1986.
What was the significance of the mysterious "Chernobyl beam of light" that was reported by eyewitnesses following the nuclear disaster?
The mysterious "Chernobyl beam of light" reported by eyewitnesses following the nuclear disaster was likely a result of the intense radiation released during the accident. This phenomenon was significant as it indicated the severity of the radiation levels and the widespread impact of the disaster on the surrounding environment.
What is the significance of the Chernobyl light beam and how does it relate to the events that occurred during the nuclear disaster?
The Chernobyl light beam, also known as the "Chernobyl Blue Beam," was a visible blue light that shot up into the sky during the nuclear disaster at the Chernobyl power plant in 1986. This light beam was caused by ionization of the air due to the extreme heat and radiation released during the explosion. The significance of the Chernobyl light beam lies in its eerie and haunting appearance, serving as a visual representation of the catastrophic events that unfolded at the plant. It symbolizes the immense power and destructive force of nuclear energy, as well as the lasting impact of the disaster on the environment and human health.
The world's nuclear power plant disaster occured in chernobyl a northern city in it became an independent from the former USSR in 1991?
The Chernobyl nuclear disaster occurred on April 26, 1986, in Ukraine within the then Soviet Union. This catastrophic event was the result of a flawed reactor design and human error during a safety test. The repercussions of the disaster had far-reaching environmental and health consequences and led to the eventual independence of Ukraine from the Soviet Union in 1991.
Why were the people of the chernobyl disaster not immediately informed?
During the Chernobyl disaster, Soviet authorities initially tried to cover up the extent of the accident to prevent panic and maintain the perception of nuclear safety. Information was restricted due to concerns about political fallout and damaging the reputation of the nuclear industry. It was not until radiation levels were detected in other countries that the severity of the accident became public.
How many people were evacuated in the chernobyl disaster?
During the Chernobyl disaster in April 1986, approximately 115,000 people were evacuated from the surrounding areas, particularly the city of Pripyat and nearby towns. An additional 220,000 people were later resettled from the most contaminated regions. The evacuation efforts aimed to protect residents from the harmful effects of radiation released during the nuclear accident.
What key insights were revealed during Valery Legasov's testimony regarding the Chernobyl disaster?
Valery Legasov's testimony during the Chernobyl disaster revealed key insights about the lack of safety measures, design flaws in the reactor, and the failures of the Soviet system in managing the crisis. He highlighted the importance of transparency, accountability, and international cooperation in preventing future nuclear disasters.
To find out what happened at chernobyl?
The Chernobyl disaster occurred on April 26, 1986, at the Chernobyl Nuclear Power Plant in Ukraine. A reactor exploded during a safety test, releasing a significant amount of radioactive material into the atmosphere. The explosion caused widespread contamination and led to the evacuation and resettlement of thousands of people.
Where is chernobyl and what happened there in 1986?
Chernobyl is located near the city of Pripyat in northern Ukraine, close to the border with Belarus. In April 1986, the Chernobyl Nuclear Power Plant experienced a catastrophic explosion during a safety test, leading to a massive release of radioactive materials into the atmosphere. This disaster is considered one of the worst nuclear accidents in history, resulting in widespread environmental contamination and long-term health effects for those exposed to the radiation. The area around the plant remains largely uninhabited due to the residual radioactivity.
What did you learn from chernobyl?
The Chernobyl disaster highlighted the catastrophic potential of human error and inadequate safety measures in nuclear power generation. It underscored the importance of rigorous regulatory oversight, transparency, and a culture of safety within the nuclear industry. Additionally, the long-term environmental and health impacts demonstrated the need for effective disaster preparedness and response strategies, as well as the importance of public communication during crises. Overall, Chernobyl serves as a critical lesson in the balance between technological advancement and safety.
