There are indications that the annual infestation of jellyfish in Chesapeake Bay waters is worse this year than in prior years.
An overabundance of jellyfish in the Chesapeake Bay is causing problems for power plants in Maryland. According to reports filed with the U.S. Nuclear Regulatory Commission, jellyfish have clogged intake pumps three times this month at the Calvert Cliffs Nuclear Power Plant in Calvert County, Md.
On July 7, an influx of jellyfish in a pump that circulates cooling water forced the plant to reduce the power output of its Unit 1 to 41 percent of capacity.
Jellyfish are not the only marine species recently to beset the Calvert Cliffs power plant. The plant reported Tuesday to the NRC that 150 to 200 cow-nosed rays had died on trash racks protecting water intakes of both units. "The apparent cause was low oxygen levels in the Bay water," the report said.
