Jellyfish-like creature forces Diablo into partial shutdown

An influx of a jellyfish-like creature into the intake at Diablo Canyon nuclear power plant has forced operators to reduce power to 15 percent capacity.

On Monday night, operators discovered a clog of a small barrel-shaped plankton called salps in the unit two intake. In response, crews reduced power to 15 percent on unit two.

Earlier this week operators shut down unit one for a scheduled refueling.

Diablo Canyon produces enough electricity to power more than 3 million homes.
