The Diablo Canyon Independent Safety Committee (DCISC) is a three-person committee charged with reviewing and making recommendations concerning the safety of operations at Pacific Gas and Electric Company“s (PG&E) Diablo Canyon Nuclear Power Plant (DCPP).
The Committee was created by the State of California's Public Utilities Commission (CPUC) and held its first meeting in May 1990.
The Diablo Canyon Power Plant is located on a 750-acre site along the central California coastline in San Luis Obispo County.
Diablo Canyon provides electricity for more than two million northern and central Californians from operation of its two 1,100 megawatt Westinghouse 4-loop pressurized water reactors fueled by uranium dioxide. Diablo Canyon began commercial operation in 1985 and is licensed by the U.S. Nuclear Regulatory Commission (NRC) to continue operating Unit-1 until 2024 and Unit-2 until 2025.
The Committee holds public meetings and plant tours, conducts inspections and publishes an annual report on the safety of Diablo Canyon, assisted by technical consultants and legal counsel.
