Google Knowledge Facilities Are Returning Nuclear Energy to Twister Nation

When a derecho slammed into the Duane Arnold nuclear plant in 2020, Diana Lokenvitz had time for precisely one look out her window.

A wall of clouds had poured in from the west, swallowing Palo, Iowa, in darkness. “It was like it was pitch black night,” the senior methods engineer on the plant recalled.

Then, the alarm started to sound.

Inside seconds of the storm hitting the plant, 130-mile-per-hour winds had severed all six of its exterior energy traces, triggering an computerized emergency shutdown.

Backup diesel turbines roared to life, and enormous management rods slid into the reactor core to halt the fission response driving the plant’s power manufacturing.

With the reactor core nonetheless dangerously sizzling, security methods kicked in to assist stabilize the reactor and vent extra warmth, a course of that lasted for hours.

“It wasn’t until we went outside afterwards that we realized that the cooling towers were gone,” Lokenvitz recalled.

Twelve water-cooling towers as soon as watched over the plant like two rows of troopers, releasing steam from water used to chill the nuclear reactor. The storm toppled them.

The derecho, a thunderstorm characterised by excessive wind gusts spanning a number of hundred miles, had swept throughout the Midwest, inflicting widespread energy outages and catastrophic injury to buildings, timber and tens of millions of acres of crops.

After 45 years of operation, the Duane Arnold Vitality Middle was shut down. The plant was already scheduled for decommissioning inside months, leaving little time or monetary incentive to restore the storm-damaged facility.
