On December 14, 2021, PG&E filed the 2021 Nuclear Decommissioning Cost Triennial Proceeding (NDCTP) with California Public Utilities Commission (CPUC).  This cost estimate must be updated and filed with the CPUC every three years.

The updated 2021 Decommissioning Cost Estimate for DCPP is $4.1B (2020$), which is a cost savings of $300M compared to the approved settlement for the 2018 NDCTP. A key highlight of the revised cost estimate is transferring all spent nuclear fuel (SNF) to dry cast storage at the Independent Spent Fuel Storage Installation (ISFSI) after 3.25-years of cooling in the spent fuel pools (contingent upon necessary regulatory approvals).  The Diablo Canyon Decommissioning Engagement Panel’s Strategic Vision document was also included in the 2021 filing.

To view the 2021 NDCTP filing documents go to https://pgera.azurewebsites.net/Regulation/search and select “Nuclear Decom Cost Tri 2021 {A.21-12-000]” in the dropdown box.

Interested parties will have 30 days to file a response or protest PG&E’s application and, in turn, PG&E will have 10 days from the end of the 30-day period to file a reply to parties.  The CPUC administrative law judge (ALJ) will announce and hold a prehearing conference and issue a scoping memo to identified parties/intervenors with the determined issues, procedural schedule and the need for hearings. The CPUC has 18 months to issue its Proposed Decision, after which a 20-day public comment period will follow. The CPUC commissioners will vote on a final decision no sooner than 30 days from when the Proposed Decision is issued.

Diablo Canyon
Decommissioning Engagement Panel
Strategic Vision

Since its creation in May 2018, the Diablo Canyon Decommissioning Engagement Panel has conducted public meetings and workshops on key topics of decommissioning, including Decommissioning Process, Decommissioning Funding, Use of Diablo Canyon Lands, Repurposing of Diablo Canyon Facilities, Emergency Services, Storage of Spent Nuclear Fuel, Performance and Structure of the Panel, and Economic Opportunities and Impacts of Decommissioning. The Panel has prepared a Strategic Vision Report that includes vision statements, goals and specific recommendations for these key areas of decommissioning based on the community input and technical presentations at the meetings and workshops. The Strategic Vision was submitted to PG&E and the California Public Utilities Commission in 2018 and has been continuously updated as new decommissioning topics are addressed.

Community Meetings and Workshops have addressed the following topics
