The Chernobyl Disaster (1986): Teaching Students About The Future of Energy

Introduction to The Chernobyl Disaster

The Chernobyl Disaster of April 25th, 1986, in Pripyat, Northern Ukraine, marked a tragic turning point in the promise of nuclear power at the birth of the atomic age. Initially seen as a means for humanity to harness vast quantities of clean energy at a reasonable price, the events that unfolded in Chernobyl transformed this vision into a haunting nightmare.

Heroic Sacrifice of Chernobyl’s Firefighters

When Reactor 4 was shut down for routine maintenance at the Chernobyl Nuclear Power Plant, technicians decided to run a test to improve its safety. The result was a disaster! Two explosions tore off the reactor’s 1,000-ton steel-and-concrete roof and sent a fireball of radioactive fission products and carbon debris into the air.

When the first firefighters arrived to extinguish the radioactive fires, they were unaware that they were entering a toxic environment – radioactive hell! Their bodies absorbed many lifetime doses of lethal radiation while they labored tirelessly without respirators, protective clothing or safety equipment to extinguish the fires, and prevent them from spreading to the other three reactors. The firefighters’ monument pays homage to the brave men who perished on that fateful night. The plaque on the monument is inscribed “To those who saved the world.”

The Urgent Evacuation and Rise of the Chernobyl Liquidators

In the hours after the disaster, the population of Pripyat was evacuated. To avoid panic, the citizens were told that this would be a temporary affair, lasting only 3 days. And so were instructed to take only necessities with them. In less than three hours the city was devoid of all life, and it would stay that way forever.

In an attempt to limit radiation exposure, the authorities used radio-controlled heavy equipment to clean the debris off the roof, but they quickly broke down under the intense radiation. Therefore, with time running out, they were left with little choice but to use military personnel, reservists, and civilians, to remove the debris, using shovels and sometimes their hands. They were to be known as the Liquidators of Chernobyl. A large majority protected only by home-made suits, gloves and respirators.

Over the next couple of weeks, nearly 600,000 liquidators worked to secure the 30-kilometre zone that circled the accident site, and built a concrete sarcophagus over the destroyed reactor to contain the radiation. They are the unsung Heroes of Chernobyl, sacrificing their lives so that we can all be here today. Their contribution must never be forgotten because without them the radiation plume would have spread throughout Europe contaminating rivers, cities and farmland for hundreds of thousands of years.

Chernobyl’s Impact: Reflections on Tragedy, Courage, and Our Energy Future

Today nobody lives in Pripyat, the city has been preserved in time. It will not be safe for people to inhabit for several centuries. The unprecedented scale of the accident has meant that it’s hard for the rest of the world to imagine the devastation this disaster has visited on the people of this land. The facts and figures can’t capture the misery and anguish that the people have experienced.

We live in a world of choices, the firefighters, who arrived at the scene saw the hot radioactive graphite from the core of the nuclear plant but they still decided to do their job valiantly. The liquidators, who spent many months building the coffin that surrounds the nuclear power plant even though their bodies absorbed lifetime doses of radiation. And the hundreds of scientists still there today risking their lives to build a new safer structure around the plant to prevent future leaks from the reactor. Chernobyl highlights human courage, sacrifice and determination over extraordinary odds. All choices made by ordinary people.

The tragedy at Chernobyl will always be remembered as the worst nuclear accident in the history of mankind. However, thankfully, nuclear accidents are a rarity with only 3 major accidents occurring since the beginning of the atomic age. That is not a bad statistic considering that there are over 450 active nuclear power stations around the world. Nuclear power is one of the most energy dense fuels that humanity has ever known, 1 kilogram of Uranium can match the energy output of 15 tons of coal, providing energy without greenhouse emission for decades.

As a larger proportion of the world is welcomed into the 21st century, our energy needs will skyrocket. How will our atmosphere look in 100 years if rising superpowers like China are burning almost as much coal as the rest of the world combined. What if we carried on with this trajectory and welcomed India and Africa into the equation too? The picture is bleak! Burning coal will not an option, we must think of alternatives, including new age nuclear power stations if we are to prevent an even greater global disaster – Climate Change.

In our complex, interdependent world, it is critical for science teachers to prepare students for the road ahead. In my classroom, my students debate openly about energy policy, students are taught that decisions made now will have profound impact on their lives, the economy, national security and the environment. Chernobyl is used as a case study about sacrifice, courage and a case against nuclear power. For me preparing my students for a bold new world is a priority for the continued success of humanity on planet Earth.
