Did you know that May 1 was among the holidays in the Soviet calendar? The holiday is called worker’s festival and is celebrated all over the Soviet Union in remembering what happened days before – known as Chernobyl explosion.

It was the Soviet leadership’s unsure response that cost the lives of many, making the end of the USSR.

Do you want to know more about the Chernobyl Explosion and how it affects the history of the Soviet Union? In this video, let us go back in time and learn more about the Chernobyl explosion’s fateful night.

Chernobyl Explosion: An Overview  

It was on  April 25-26 when the Chernobyl explosion happened in the nuclear power station. The Ukrainian Soviet Specialist Republic was one of the constituent republics of the USSR.

Did you know that the explosion released a very large amount of fatal radioactive materials that spread far outside the disaster zone and the environment?

The emergency crews responded to the accident using helicopters to pour boron and sand on the reactor debris. The boron was to prevent any additional nuclear reactions, while the sand was intended to put the fire down and release additional radioactive material.

Also, the crews covered the damage weeks after the accident in a temporary concrete structure and called it a “sarcophagus.” This concrete structure was to limit the release of radioactive material.

More so, the Soviet government also buried and cut down a square mile of a pine forest just near the plant. This is to reduce radioactive contamination near and at the site.

Three other reactors of Chernobyl then restarted but eventually had to shut down for good. The last reactor closed in 2000.

In 1986, authorities of the Soviet nuclear power presented the initial report to the International Atomic Energy Agency meeting in Vienna, Austria.

After the incident, authorities closed the area, about 18 miles from the plant. The Soviet government evacuated almost 115,000 people from contaminated areas and about 220,000 in the following years. Only those with business at the plant and evaluators dealing with the accident’s consequences can get in.

Why Did the Incident Happen?

Before the routine shutdown, the reactor crew at the Chernobyl 4 started to prepare for the test and determine how long the turbines supply power and spin to its main circulating pumps. Little did they know, it also followed the loss of the main electrical power supply.

Yes, the test was done the previous year, but the power from the turbine ran down too fast. That’s why new voltage regulator designs had to be tested. With that, a series of operator actions included restricting the shutdown mechanisms and headed the attempted test early on April 26.

At that time, the operator moved to shut down the reactor, which was then an extremely unstable condition. The design of control rods caused a dramatic surge of power as they were inserted into the reactor, which resulted in the interaction of cooling water and hot fuel.

This led to fuel fragmentation, fast steam production, and pressure increase, and caused substantial damage to 3 or 4 fuels. And it did and destroyed the reactor.

Because of this, an intense steam generation spread through the entire core and caused the steam explosion and release of fission products into the atmosphere. Worse is that, about 2-3 seconds later, another explosion threw out wreckages from the hot graphite and fuel channels.

What is Its Impact to the History of the Soviet Union? 

The Chernobyl Explosion caused the largest uncontrolled release of radioactive materials in the environment. And it lasted for about ten days!

The incident caused harsh social and economic trouble for populations in Russia, Belarus, and Ukraine. There were 2 radionuclides; the short-lived iodine – 131 and long-lived caesium -137. These were mainly important for the contamination dose delivered to the public members.

Other Effects on Soviet Union History 

Aside from the effects of this incident on people’s lives, the Chernobyl Explosion also changed the history of the Soviet Union.

Mayday Parades 

There were reports of coverups about this catastrophe. The troubling aspect of this coverup was about the Moscow authorities and their persistence for May Day parades in Kyiv to go normal.

It’s their way of convincing the people that nothing is wrong. Those celebrating the holiday put themselves at risk from the radiation. However, this kind of insensitivity had a price, as it undermined the assurance of the ability to lead the authorities.

Protest, Economy, and Politics

The Chernobyl explosion released a mass protest movement against authorities. The Soviet Union ended in 1991, and the reactor explosion became a fall in the USSR.

It does not only cost lives, but the nature and delayed effects mean that the true death toll will never be known. It also contributed to ending the political and economic system. It fueled the global anti-nuclear movement, and it beckons to tourists who are also intrigued by its danger and history.

Chernobyl Today 

In 2022, the Russian forces took control of all the facilities of the nuclear plant of Chernobyl. The control levels of the gamma radiation during the explosion were exceeded. The rise in radiation levels was likely because of the disturbance of the top layer of soil from moving a large number of heavy military machinery through the exclusion zone.

Long-term Impacts 

The impact of the Chernobyl explosion on the surrounding wildlife and forest remains a place of active research. The aftermath of the incident is an area of about 4 square miles and became known as “Red Forest,” as many trees became reddish-brown and later died after they absorbed high levels of radiation.

Conclusion

After knowing what happened, do you realize how hard it was for the people and authorities when the incident happened?

Though the Chernobyl explosion symbolizes the potential damage of nuclear power, Russia is still firm and never moved beyond its legacy or even its technology. Perhaps, this incident became a lesson not only to the Soviet Union but also to the world.
