On Wednesday, operators at the Diablo Canyon nuclear power plant manually scrammed the Unit 2 reactor “due to an influx of sea salp – a small, jellyfish-like organism – in the intake structure.” The plant activated the reactor’s auxiliary feedwater pumps to cool the reactor in the absence of seawater.
Makes you wonder how the designers of the plant sold the concept: “This’ll work, unless there’s, I don’t know, sea life in the seawater. Then the whole thing shuts down. You ever try to clean jellyfish out of a fine-mesh screen?”
With the shutdown of Unit 2, and Unit 1 being offline for refueling, Diablo Canyon is currently producing no electricity.
