Understanding the Chernobyl Nuclear Reactor Explosion

The catastrophic event of the Chernobyl nuclear reactor explosion took place on a Saturday, specifically on April 26, 1986. This tragic incident resulted from an unauthorized experiment that was being conducted with safety devices turned off, which caused one of the reactors to become unstable.

The instability of the reactor led to an uncontrollable chain reaction, surpassing the reactor's design limits and causing a significant increase in steam pressure within the reactor core. This pressure escalated to between 100 and 500 times the full power pressure, leading to a rupture in the reactor and a subsequent explosion.

Due to the absence of a containment building for the reactor, a massive amount of radioactive material was released into the surrounding environment. Additionally, fission products escaped as the graphite moderator of the core ignited and burned, exacerbating the contamination.

In the aftermath of the explosion, over 200 plant workers and firefighters developed acute radiation sickness, with at least 32 individuals succumbing shortly after due to the severe effects of radiation exposure. The long-term consequences of the Chernobyl disaster continue to manifest in the region, leaving it largely uninhabitable and deserted.
