On April 26, 1986, engineers at the Chernobyl nuclear power plant were carrying out a safety test to find out what would happen if the cooling systems ever failed. They shut off emergency cooling and began powering down the reactor. But it started falling too fast. Under pressure to get the test done, they removed more and more control rods to bring power back up—a move that wasn't in the safety handbook. When the test began, power surged unexpectedly. Thirty seconds later, someone pushed the big red stop button, the AZ-5, which should have plunged all control rods into the core and stabilized things. Instead, the fuel had gotten too hot, burst its casings, and jammed the rods. Power kept rising. Steam built up. After five seconds, the core detonated with the force of sixty tons of TNT.
The reactor that was built for two purposes

We go deep inside the Chernobyl nuclear-power plant and the surrounding exclusion zone, recounting the history of the accident on April 26 1986, and speaking with plant workers who were on shift that day. A pre-eminent Chernobyl historian discusses the lessons learned and yet to be learned from the disaster. And we consider the science still being done at Chernobyl.
In 2024 “The Weekend Intelligence” went to Ukraine to consider the aftermath of the Russian invasion and occupation of Chernobyl, and then of the Zaporizhia nuclear-power plant. What we found was an industry that had no expectation that could even happen, and nothing of a plan when it did. Listen here.
