Dear Commissioners and Staff:

Pacific Gas and Electric Company (PG&E) is submitting the decommissioning funding report for Diablo Canyon Power Plant (DCPP), Units 1 and 2, pursuant to the requirements of 10 CFR 50.75(f). In Reference 1, PG&E submitted the site-specific decommissioning cost estimate (DCE) for DCPP Units 1 and 2. In accordance with 10 CFR 50.82(a)(8)(v), after submitting the site-specific DCE, and until the licensee has completed its final radiation survey and demonstrated that residual radioactivity has been reduced to a level that permits termination of its license, licensees must annually submit to the NRC, by March 31, a financial assurance status report. In addition, in accordance with 10 CFR 50.82(a)(8)(vii), after submitting the site-specific DCE, the licensee must annually submit to the NRC, by March 31, a report on the status of funding for managing irradiated fuel.

In Reference 2, the NRC granted PG&E an exemption request to allow withdrawal of

$187.8 million ($2017) from the Diablo Canyon Nuclear Decommissioning Trust (NDT) to fund radiological decommissioning, spent fuel management, and site restoration planning activities prior to permanent cessation of operations. However, as of the date m

• Wolf Creek of this submittal, PG&E has not withdrawn any funds from the Diablo Canyon NDT to support decommissioning activities.

Diablo Canyon Power Plant, Units 1 and 2 At the end of calendar year 2021, the market values of the DCPP Units 1 (3411 MWt) and 2 (3411 MWt) decommissioning trust fund were $1,921.7 million and

$2,513.5 million, respectively. PG&E currently has more funds in the DCPP, Units 1 and 2, decommissioning trust fund than required to meet the minimum NRC decommissioning amount of $706.8 million (2022 dollars) for each unit that was calculated pursuant to the requirements of 10 CFR 50.75(c).

Supporting Cost Estimates PG&E prepared a site-specific DCE that was submitted to the California Public Utilities Commission (CPUC) in the 2021 Nuclear Decommissioning Cost Triennial Proceeding (NDCTP) on December 14, 2021. PG&E does not expect a final ruling in the 2021 NDCTP until 2023. Based on this site-specific DCE provided, PG&E estimates that the license termination decommissioning costs are about $1,270.2 million for DCPP Unit 1 and $1,182.3 million for Unit 2 in 2022 dollars. These costs do not include site restoration of the facilities ($674.9 million in 2022 dollars) or spent fuel management costs ($951.1 million in 2022 dollars) after shutdown of Units 1 and 2.

To assure that sufficient funds will be available for decommissioning, PG&E has established separate external sinking trust fund accounts for DCPP, Units 1 and 2. As part of the final decision in the 2018 NDCTP, PG&E will not collect any additional funds in the NRC-jurisdictional Qualified NDT. The final decision in the 2018 NDCTP did authorize PG&E to deposit additional contributions to a non-qualified trust fund or other non-qualified mechanism, which will include subaccounts to track separately the costs associated with license termination, spent fuel management and site restoration. As demonstrated in this submittal, PG&E's NRC-jurisdictional Qualified NDT is fully funded for the projected costs of radiological decommissioning for DCPP, Units 1 and 2. The non-qualified trust which was authorized by the CPUC is not subject to NRC-jurisdiction.

PG&E did not request any additional collection from customers in the 2021 NDCTP.

As provided in 10 CFR 50.75(f)(1), each power reactor licensee is required to report to the NRC on a calendar year basis, beginning on March 31, 1999, and every 2 years thereafter, on the status of its decommissioning funding for each reactor or share of reactor it owns. Any licensee for a plant that is within 5 years of the projected end of its operation, shall submit this report annually.

Note that items 3 and 8 are data included in PG&Es Nuclear Decommissioning Cost Triennial Proceeding (NDCTP) filed with the California Public Utilities Commission (CPUC) on December 14, 2021. A final ruling in the case is not expected until the second quarter of 2023.

1 The NRC formulas in section 10 CFR 50.75(c) include only those decommissioning costs incurred by licensees to remove a facility or site safely from service and reduce residual radioactivity to levels that permit: (1) release of the property for unrestricted use and termination of the license; or (2) release of the property under restricted conditions and termination of the license. The cost of dismantling or demolishing non-radiological systems and structures is not included in the NRC decommissioning cost estimates. The costs of managing and storing spent fuel on site until transfer to United States Department of Energy are not included in the cost formulas.
