Salp invasion cuts nuclear power output

Jellyfish-like creatures force California nuclear power plant to curtail operations By Steve Chawkins / Los Angeles Times, 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 plant’s operator, Pacific Gas & Electric, cut power generation from one of the plant’s 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 andScotland. …. http://news.bostonherald.com/news/national/west/view/20120426jellyfish-like_creatures_force_california_nuclear_power_plant_to_curtail_operations/srvc=home&position=recent
