What Occurred at Chernobyl: Timeline & Causes Discussed
The Chernobyl disaster on April 26, 1986, is among the most catastrophic nuclear accidents ever. An ill-fated reactor design and some critical human mishaps led to the explosion of Reactor No. 4, which spewed huge quantities of radioactive material all over Europe. A complete account of the Chernobyl incident has been presented in this article in the form of a summary followed by a detailed chronology.
In addition, it will also contain a step-by-step guide on how to make your own Chernobyl events timeline and discuss the most important factors that contributed to the disaster. Collectively, these sections provide a better insight into this historic disaster.

Part 1. The Chernobyl Events
A defective reactor design and poorly educated operators were the cause of the 1986 Chernobyl disaster. At least 5% of the radioactive reactor core was discharged into the environment as a result of the ensuing steam explosion and fires, which caused radioactive material to be deposited throughout much of Europe.
The explosion on the night of the catastrophe killed two workers at the Chernobyl facility, and acute radiation sickness claimed the lives of another 28 people within a few weeks. Except for about 5000 thyroid tumors, which led to 15 deaths, the United Nations Scientific Committee on the Effects of Atomic Radiation has determined that there is no evidence of a major public health impact attributable to radiation exposure 20 years after the accident.
The catastrophe resulted in the evacuation of about 350,000 people, although the places from which they were moved are still being resettled. With all of these details, let us now see the great Chernobyl events timeline brought to you by MindOnMap.
Part 2. The Chernobyl Events Timeline
The catastrophic nuclear disaster referred to as the Chernobyl tragedy occurred at Ukraine's Reactor No. 4 in 1986. This timeline identifies the key events preceding, during, and after the explosion, focusing on both its short-term and long-term impacts on the international community.
1970
Work on the Chernobyl Nuclear Power Plant commences in northern Ukraine, close to the town of Pripyat. The plant will be capable of accommodating four RBMK-type nuclear reactors.
1977
Reactor No. 1 becomes operational, with the remaining reactors going online in subsequent years. This was the start of the Chernobyl Nuclear Power Plant's operational involvement in energy generation for the Soviet Union. Plans called for four RBMK reactors to be housed within the plant, and it soon became an integral part of the power generation infrastructure of the region.
1983
Reactor No. 4 is completed and begins operation. This reactor would eventually be the location of the disastrous explosion.
1986
Reactor No. 4 blows up on April 26, during a safety test conducted in the middle of the night, spilling huge quantities of radiation into the environment. More than 50,000 Pripyat citizens were evacuated the next day, and global attention increased after the detection of radiation in Sweden.
1991
There is a fire in Reactor No. 2, and it is closed permanently. Concerns by now for the safety of the other reactors are ongoing.
2000
Reactor No. 3, the final operational unit at Chernobyl, is closed down under international pressure. The plant officially closed down after 23 years.
2016
The New Safe Confinement building is finished and slid into position over the previous sarcophagus. This new containment shield will keep radiation leaks from occurring for the next 100 years.

That is the simple and great performance of MindOnMap in creating your timeline without complication. Please follow the guide above and expect a great outcome after that. Use it now and discover more of the things it can offer!
Part 4. What Caused the Chernobyl Event
The Chernobyl disaster resulted from a combination of human mistake, inadequate planning, and severe design defects in the reactor. Operators shut down vital safety systems and operated the flawed RBMK reactor at perilously low power during a late-night safety test. These errors, coupled with the reactor's defective design, created an uncontrolled power surge and a huge explosion. See more points below about it.
Faulty Reactor Design (RBMK-1000)
The reactor was critically faulted in its design, as it was unstable at low power and had a positive void coefficient, which would make it risky to operate at some levels.
Unsafe Safety Test
An ill-conceived safety test was initiated to mimic loss of power with no safety equipment in place to prevent it.
Operator Error
Plant operators abused procedures, disconnected safety systems, and disregarded warning signs, resulting in losing control.
Low Power Operation
The reactor was operating at very low power levels, which added to instability and made it highly susceptible to a power surge.
Withdrawal of Control Rods
Almost all control rods were pulled out in order to keep power, which seriously reduced the ability of the reactor to regulate itself.
Part 5. FAQs about Chernobyl Events Timeline
What was the number of Chernobyl explosions?
The disaster happened at 01:23 on Saturday, April 26, 1986, when the reactor building's roof and Unit 4's core were destroyed by two explosions.
For how number of years will Chernobyl be safe?
Additionally, people impacted by Chernobyl radiation work fewer hours and have lower employment rates than the general Ukrainian population. The area surrounding the nuclear facility will remain unsafe for human habitation for at least another 20,000 years, even with the new bunker over the crippled reactor unit 4.
In reality, how many people perished at Chernobyl?
Official accounts state that 600,000 liquidators, who worked in firefighting and cleanup operations, were exposed to significant radiation doses, and that 31 individuals perished instantly.
Are you able to go to Chernobyl today?
You can, indeed. We can plan a journey on any day that works for you because we are the authorized firm to arrange tours to the Exclusion Zone.
Do the three Chernobyl heroes still live?
With all three guys avoiding such a horrific end, the reality is far more optimistic than the myth. Boris Baranov survived until 2005, when he died of heart disease, but Valeri Bespalov and Alexei Ananenko are thought to still be alive as of 2024.
Conclusion
The Chernobyl disaster is a sad reminder of the risks involved in nuclear power and the importance of safety, openness, and preparedness. Having an understanding of the sequence of events and why they occurred enables us to learn from the past and not repeat the same errors in the future. Building a thorough timeline not only places the facts in sequence but also adds to our knowledge of how the disaster occurred. With tools such as MindOnMap, it has never been easier to create a great graphic timeline. Through delving into the Chernobyl events, their timeline, and causes, we learn valuable information about one of history's most significant nuclear disasters.Thanks to their timeline maker!
