Researchers are launching a new project to monitor California's kelp forests for radiation from the Fukushima nuclear power plant in Japan. Scientists will fan out along the California coast to collect kelp and find out if it has absorbed any radiation from the 2011 meltdown.
The San Onofre nuclear plant has not operated since January 2012, when a radioactive leak was discovered in one of its generators. The permanent closure could put pressure on California's electrical grid in the long-term. The California Independent System Operator, which manages the grid, does not expect statewide problems with power supply this summer.
