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.

Document Control Desk PG&E Letter DCL-20-014 March 30, 2020 Page 2 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 (NOT) to fund radiological decommissioning, spent fuel management, and site restoration planning activities prior to permanent cessation of operations. However, as of the date of this submittal, PG&E has not withdrawn any funds from the Diablo Canyon NOT to support decommissioning activities.

Diablo Canyon Power Plant, Units 1 and 2 At the end of calendar year 2019, the market values of the DCPP Units 1 (3411 MWt) and 2 (3411 MWt) decommissioning trust fund were $1,540.3 million and $2,015.0 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 $675.2 million (2020 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 decommissioning cost estimate that was submitted to the California Public Utilities Commission (CPUC) in the 2018 Nuclear Decommissioning Cost Triennial Proceeding (NDCTP) on December 13, 2018.

Based on this site-specific decommissioning cost estimate, PG&E estimates that the license termination decommissioning costs are about $1,645.2 million for DCPP Unit 1 and $1,642.5 million for Unit 2 in 2020 dollars. These costs do not include site restoration of the facilities ($759.6 million (2020 dollars)) or spent fuel management costs after shutdown of Units 1 and 2 ($1,286.4 million (2020 dollars)). 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.

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.

Supporting Enclosures provides decommissioning funding status information in a format suggested by the Nuclear Energy Institute (NEI) and the NRC. provides information on the escalation of the required decommissioning funding amounts from 1986 dollars to 2020 dollars. As required by 10 CFR 50.75(c)(2), and using NUREG-1577, "Standard Review Plan on Power Reactor Licensee Financial Qualifications and Decommissioning Funding Assurance,"

Revision 1, and NUREG-1307, "Report on Waste Burial Charges," Revision 17, the information includes escalation factors for energy, labor, and waste burial costs.

Document Control Desk PG&E Letter DCL-20-014 March 30, 2020 Page 3 NUREG-1307, Revision 17, assumes for plants that have no disposal site available within their designated low-level waste (LLW) compact, that the cost for disposal of Class A LLW is the same as that for the Clive, Utah disposal facility and for Class B and C LLW is the same as that for the Andrews County, Texas disposal facility including accounting for out-of-compact fees. The State of Texas limits the total non-compact waste disposed at the Compact Waste Facility (CWF) in Andrews County, Texas for out-of-compact generators to 30-percent of licensed capacity. DCPP does not have a disposal site available within its designated Southwestern LLW Compact.

NUREG-1307, Revision 17, states that, given these considerations, licensees may want to set aside additional decommissioning trust funds to cover associated future decommissioning costs. Based on the limited number of CWFs currently available and the potential for limited to no availability at the Texas CWF for DCPP LLW disposal when PG&E begins LLW disposal associated with decommissioning, PG&E has used the formula, coefficients, and adjustment factors from NUREG-1307, Revision 17 in the cost analyses, with the exception of the burial/disposition factor.

As allowed per NUREG-1307, Revision 17, PG&E used a burial/disposition adjustment factor higher than the burial/disposition adjustment factor provided in NUREG-1307, Revision 17, for plants that have no disposal site available within their designated LLW Compact. To avoid significant future shortfalls in funding and potential enforcement actions, PG&E used the burial/disposition adjustment factor for compact-affiliated disposal for the South Carolina site. The specific decommissioning cost estimate results in a total cost estimate of no less than the amount estimated by using the parameters presented in NUREG-1307, Revision 17, while accounting for the potential future shortfall in disposal capacity at the CWF in Andrews County, Texas. is a modified version of Table 6-1, "Decommissioning Milestones," from the 2018 NDCTP, adjusted for time period, funding category and man hours. PG&E then adjusted the cost estimate to reflect costs in nominal/2020 dollars per the NDCTP submitted on December 13, 2018, to the CPUC by applying the escalation factors included in the submittal. The report provides cost estimates for decommissioning of both nuclear and non-nuclear facilities, including the Diablo Canyon Independent Spent Fuel Storage Installation. 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 4 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.

Document Control Desk PG&E Letter DGL-20-014 March 30, 2020 Page 4 In Reference 3, PG&E submitted the 2019 Decommissioning Funding Report for DCPP, Units 1 and 2. As discussed in Reference 3, PG&E maintains an NOT with separate accounts for each unit. The balance for each account represents a total amount accumulated for decommissioning and is not separated into sub-accounts for radiological decommissioning, spent fuel management, and site restoration.

PG&E has evaluated the need for a mechanism to separate the total trust balance for each unit into funds accumulated for the three categories. The NOT was not originally set-up with sub-accounts and no accounting mechanism was established to distinguish between funds collected for radiological decommissioning, spent fuel management and site restoration. PG&E has determined that at this time, the existing NOT account will not be segregated into separate sub-accounts for the three categories . Therefore, the balance in the existing NOT for DGPP Units 1 and 2 will be managed in accordance with NRG regulations, as funds collected for radiological decommissioning.

As part of PG&E's NDGTP, PG&E filed a OGE with the GPUC on December 13, 2018. PG&E and several interested parties to the 2018 NDGTP have filed a settlement agreement that if approved, could impact the information included in this submittal. PG&E is anticipating a final decision by the GPUC in mid-2020. Updates to the information included in this submittal will be included in future submittals .

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.

Note (f): Effective with NUREG-1307, Revision 8 (Reference3) an alternative disposal option was introduced in which the bulk of the LLW is assumed to be dispositioned by waste vendors and/or disposed of at a non-compact disposal facility.

Note (g): Effective with NUREG1307, Revision 15, the nomenclature for the two disposal options, referred to as "Direct Disposal" and "Direct Disposal with Vendors" in previous revisions of NUREG-1307, is changed to "Compact-Affiliated Disposal.

Facility Only" and "Combination of Compact-Affiliated and Non-Compact Disposal Facilities" to better describe the options.

Note (h): 2013 has no information in NUREG-1307 Revision 15. 2013 is an estimate that is calculated by applying the percent change between 2010 and 2012 and adding to the 2012 base.

Note (i): 2015 The NRC has issued Regulatory Issue Summary 2014-12, "Decommissioning Fund Status Report Calculations Update to Low-Level Waste Burial Charge Information," to inform licensees that they may use low-level waste burial charge data contained in Revision 15 of NUREG-1307, Report on Waste Burial Charges: Changes in Decommissioning Waste Disposal Costs at Low-Level Waste Burial Facilities, dated January 2013, when preparing their periodic decommissioning fund status report ..

Note 0): Effective with NUREG-1307, Revision 15, the nomenclature for the two disposal options, referred to as "Direct Disposal" and "Direct Disposal with Vendors" in previous revisions of NUREG-1307, was changed to "Compact-Affiliated Disposal Facility Only" and "Combination of Compact-Affiliated and Non-Compact Disposal Facilities" to better describe these options.

Note (k): As allowed per NUREG-1307, Revision 16, PG&E used a burial/disposition adjustment factor higher than the burial/disposition adjustment factor provided in NUREG-1307, Revision 16, for plants that have no disposal site available within their designated LLW Compact. To avoid significant future shortfalls in funding and potential enforcement actions, PG&E used the burial/disposition adjustment factor for compact-affiliated disposal for the South Carolina Site."
