12/31/21: Early in 2021, crews at Georgia Power’s nuclear expansion site at Plant Vogtle were struggling to find all the leaks in a pool built to hold spent, highly radioactive fuel.

They added air pressure under the floor of the water-filled pool, hoping air bubbles would pinpoint flawed welds. It didn’t work. So an engineer doubled the air pressure.

The result: The pool’s steel floor plates were damaged, rendering them unusable. New ones had to be manufactured. The fixes and rechecks of the pool have taken nearly a year and cost millions of dollars.

It’s been that kind of a year at Plant Vogtle. Though the expansion project was supposed to be close to completion, a series of missteps and botched jobs in recent months has led to more cost overruns, further delays and fresh worries about quality and oversight.

The project has had setbacks almost since it began. But the 2021 revelations highlight how widespread the problems have become.
