Chernobyl: A Ticking Time Bomb

The video discusses the Chernobyl disaster, which occurred on April 26, 1986, when a series of errors during a test at the nuclear power station led to explosions and the release of radioactive material. The disaster had widespread effects, with radioactive fallout reaching as far as Finland and Italy. Soviet soldiers and pilots worked to contain the fallout, and a sarcophagus was built over the reactor. Today, efforts continue to mitigate future risks with a new containment structure. The video also covers the engineering challenges and cooling of the reactor core.

What was the primary goal of the tests conducted by scientists at the Chernobyl nuclear power station?

• To increase the power output of the reactor
