California nuclear power plant to curtail operations
By Steve Chawkins / Los Angeles Times Thursday, April 26, 2012
LOS ANGELES -- Strange, jellyfish-like creatures swarming a coastal nuclear power plant: It might sound like the premise of a cult horror flick, but the invasion has prompted officials at the Diablo Canyon facility in San Luis Obispo, Calif., to curtail operations for at least a few days.
The plants operator, Pacific Gas & Electric, cut power generation from one of the plants two reactors to 25 percent of its capacity, spokesman Tom Cuddy said Wednesday. The other reactor was shut down this week for what PG&E described as routine refueling and maintenance, a procedure that could take about a month.
Workers on Monday discovered an influx of the creatures, called salp, clogging screens that are used to keep marine life out of the sea water used as a coolant, Cuddy said. Often thronging many square miles of ocean in huge, gelatinous masses, salp are tubular, transparent organisms that can be roughly the size of a human thumb. No one knows how many are at the Avila Beach plant or how long they will remain.

Jellyfish swarmed Diablo Canyon in 2008, triggering a steep, sudden decrease in power generation. Over the years, they have been a problem at nuclear plants in the U.S., Japan, Israel and Scotland. The San Onofre plant in northern San Diego County, while currently closed over several equipment issues, has not had a jellyfish problem, according to a spokeswoman for its operator, Southern California Edison.

"Theyre beautiful. They look like theyre made of cut glass, but theyre soft." Research by Madin and his colleagues suggests that salps play a role in reducing greenhouse gases. They absorb carbon from plankton and drop it in heavy pellets to the sea floor, where it sits, instead of rising into the atmosphere as carbon dioxide.

Because soon the oceans will contain nothing but jellies. And squid.
