San Onofre
The 50 “community alert” sirens in the 10 miles around the San Onofre nuclear power plant will be tested between 10 a.m. and noon Wednesday, Southern California Edison officials said Monday.
The sirens--situated in San Onofre State Park, Camp Pendleton, San Clemente, San Juan Capistrano and Dana Point--will be sounded twice, for two to five minutes, utility officials said.
Federal regulations require the sirens to warn of a nuclear emergency. The sirens are intended to advise people to turn on radios or television sets for instructions, utility officials said.
