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.

The evening session of the DCISC public meeting on October 23, 2019, beginning at 5:30 p.m. is intended to provide another opportunity for any member of the public to receive information and provide his or her comments concerning a potential role for the DCISC to review nuclear fuel-related issues after expiration of the operating licenses from the NRC for the Diablo Canyon Power Plant.  The following materials are provided in connection with that discussion:

  1. Present Restated Charter for the Diablo Canyon Independent Safety Committee issued on January 25, 2007 by the California Public Utilities Commission in its Decision 07-01-028
  2. A Second Restatement of the Committee’s Charter, showing proposed changes from the DCISC present Charter, which, if submitted to and approved by the California Public Utilities Commission, would provide for the DCISC’s continued review of Diablo Canyon nuclear fuel-related operations until such time as all nuclear fuel is successfully transferred to the site’s Independent Spent Fuel Storage Installation; and
  3. A Post-shutdown Summary of the phases which will follow the shutdown of the Diablo Canyon reactors, the topical areas proposed for the DCISC’s continued review, an assessment of the risk during each phase, and an estimate of the duration of each phase (PDF).
