Chernobyl’s Radioactive Lava is Still Hot
Because Science・1 minute read
The Chernobyl nuclear disaster, explored from an engineering and physics perspective, resulted from a design flaw in the RBMK reactor leading to a catastrophic meltdown in 1986. The fallout has made the surrounding areas uninhabitable for humans for centuries, but wildlife thrives in the exclusion zone.
Insights
- Chernobyl's RBMK reactor's design flaw, specifically the positive void coefficient, caused an uncontrollable feedback loop leading to the catastrophic meltdown in 1986.
- The aftermath of the Chernobyl disaster resulted in the creation of an exclusion zone, making the surrounding area uninhabitable for humans for centuries while paradoxically allowing wildlife to flourish in the absence of human presence.

Chernobyl's Radioactive Legacy: 30 Years Later
- In a basement beneath a failed Russian nuclear reactor lies two tons of radioactive lava, still hot after over 30 years.
- Chernobyl, the site of the worst nuclear disaster in history, is explored from an engineering and physics perspective in this episode.
- Nuclear reactors like Chernobyl's operate on nuclear fission, splitting unstable atoms to create energy.
- The design of nuclear reactors ensures controlled chain reactions to produce heat, which is converted into electricity.
- Chernobyl's RBMK reactor had a design flaw that led to a catastrophic meltdown on April 26, 1986.
- A positive void coefficient in the reactor caused a feedback loop, escalating heat production uncontrollably.
- The meltdown at Chernobyl resulted in explosions, fires, and the release of eight tons of radioactive material into the atmosphere.
- The Elephant's Foot, a two-ton mass of corium, remains highly radioactive and lethal even after 30 years.
- The radioactive lava from The Elephant's Foot is still burning and eating into the Earth below Chernobyl.
- The fallout from Chernobyl has rendered the surrounding areas uninhabitable for humans for centuries, but wildlife thrives in the exclusion zone.
