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 m

• Wolf Creek 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. As of the date of this submittal, PG&E has not withdrawn any funds from the Diablo Canyon NDT to support decommissioning activities.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 2020, the market values of the DCPP Units 1 (3411 MWt) and 2 (3411 MWt) decommissioning trust fund were $1,757.6 million and

$2,298.6 million, respectively. The current balance of the trust for units 1 and 2 satisfies the requirements pursuant to 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 2018 Nuclear Decommissioning Cost Triennial Proceeding (NDCTP) on December 13, 2018. On January 10, 2020, PG&E and several interested parties to the 2018 NDCTP filed a settlement agreement which is currently under review with the CPUC (Reference 3). The CPUC has extended the deadline for a decision to September 13, 2021 (Reference 4). Based on the site-specific DCE, PG&E estimates that the license termination decommissioning costs are approximately $1,711.7 million for DCPP Unit 1 and $1,709.2 million for Unit 2 in 2021 dollars. These costs do not include site restoration of the facilities ($781.5 million in 2021 dollars) or spent fuel management costs after shutdown of Units 1 and 2 ($1,327.0 million in 2021 dollars).

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 2018 NDCTP filing, PG&E requested approval from the CPUC to collect additional funds for decommissioning DCPP Units 1 and 2.

Supporting Enclosures provides decommissioning funding status information in a format suggested by the Nuclear Energy Institute (NEI) and the NRC.

• Wolf Creek is a cash flow for the total decommissioning of DCPP that identifies the monies for NRC scope (removal of radiological contamination), site restoration (including non-radiological work), and the spent fuel management based on the 2018 NDCTP Cost Estimate by unit. The cash flows provided in Enclosure 2 represent the forecasted cost for radiological decommissioning, site restoration, and spent fuel management, and do not represent separate sub-accounts within the decommissioning trust fund.

PG&E makes no new or revised regulatory commitments (as defined by NEI 99-04) in this letter.

Should you have any questions, please contact Mr. Philippe Soenen at (805) 459-3701.

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 filed with the California Public Utilities Commission (CPUC) on December 13, 2018. The CPUC has extended the deadline for a decision to September 13, 2021.

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 DOE are not included in the cost formulas.
