The United States Nuclear Regulatory Commission (NRC) lists at least 4 nuclear power plants in California. These plants are Diablo Canyon 1 and 2 located 12 miles WSW of San Luis Obispo, CA. The plants are operated by Pacific Gas & Electric Co. The plants are 310 miles from San Diego. In addition, San Onofre 2 and 3 are located 45 miles SE of Long Beach, CA. The plants are operated by Southern California Edison Company. These plants are located just 93 miles from San Diego.
The NRC’s regulations are aimed at enhancing public safety by setting forth standards for systems necessary to operate the nuclear power plant or shut it down in case of an emergency or natural exigency like an earthquake event. The safety systems’ buried piping is subject to rigorous routine inspection and testing requirements set forth in the NRC agency regulations, as well as from standards of the American Society of Mechanical Engineers.
