Reference:

NRC Letter, "Summary of November 29, 2018 Public Meeting with Pacific Gas and Electric Company to Discuss the Proposed Exemption Request to Withdraw Funds from the Nuclear Decommissioning Trusts to Fund Decommissioning Planning Activities at Diablo Canyon Nuclear Power Plant, Units 1 and 2 (EPID L-2018-LRM-0074)," dated December-31, 2018

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).

Diablo Canyon Power Plant, Units 1 and 2 At the end of calendar year 2018,. the market values of the DCPP Units 1 (3411 MWt) and 2 (3411 MWt) decommissioning trust fund were $1,306.3 million and $1,708.5 million, respectively. PG&E currently has mote funds in the DCPP, Units 1 and 2, decommissioning trust fund than required to meet the minimum NRC decommissioning amount of $670.2 million (2019 dollars) for each unit that was calculated pursuant to the requirements of 10 CFR 50.75(c). PG&E continues to fund the trust through collections for additional costs beyond those required in 10 CFR 50.75(c).

Enclosure 5 to this letter contains Confidential Information -Withhold Under 10 CFR 2.390 Document Control Desk PG&E Letter DCL-19-020 March 26, 2019 Page2 Decommissioning Cost Triennial Proceeding (NDCTP) on December 13, 2018.

Based on a site-specific decommissioning cost estimate, PG&E estimates that the license termination decommissioning costs are about $1,581.3 million for DCPP Unit 1 and $1,578.4 million for Unit 2 in 2019 dollars. These costs do not include site restoration of the facilities ($738.3 million) or spent fuel management costs

($1,245.9 million) after shutdown of Units 1 and 2.

  • To assure that sufficient funds will be available for decommissioning, PG&E has established 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 2019 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.

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 Enclosure 5 contains Confidential information - Withhold Under 10 CFR 2.390 When separated from Enclosure 5, this document is decontrolled A member of the STARS Alliance Callaway

Enclosure 5 to this letter contains Confidential Information -Withhold Under 10 CFR 2.390 Document Control Desk PG&E Letter DCL-19-020 March 26, 2019 Page 3 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/2019 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 (ISFSI). The costs included in the DCE submitted in the 2018 NDCTP are reflected in 2017 dollars, and the costs in Enclosure 3 are provided in 2019 dollars. is a cash flow for the total decommissioning of DCPP that identifies the monies for NRC scope (removal of radiological contamination), site restoration (including nonradiological 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. The costs included in the DCE submitted in the 2018 NDCTP are reflected in 2017 dollars, and the costs in Enclosure 4 are provided in 2019 dollars. contains the site-specific decommissioning cost estimate report for DCPP Unit 1 and Unit 2, prepared for the 2018 NDCTP and submitted in December 2018. The report provides cost estimates for the decommissioning of the nuclear, non-nuclear facilities, and spent fuel management, including operation and decommissioning of the ISFSI in 2017 dollars. Enclosure 5 contains confidential information that should be withheld from public disclosure in* accordance with 10 CFR 2.390. PG&E notes that the darker shaded boxes in Table 3-9 of do not contain any data. The costs included in Enclosure 5 are reflected in 2017 dollars. contains the redacted version of the site-specific decommissioning cost estimate report for DCPP Unit 1 and Unit 2 prepared for the 2018 NDCTP. The costs included in Enclosure 6 are reflected in 2017 dollars. contains a Financial Information Affidavit pursuant to 10 CFR 2.390.

The Affidavit sets forth the basis for which specific information included in may be withheld from public disclosure by the Commission and addresses the considerations listed in 10 CFR 2.390(b)(4).

On November 29, 2018, PG&E had a meeting with the NRC to discuss an exemption request related to the DCPP Decommissioning Trust Fund (Reference 1).

Based on discussions during the meeting, related to previous DCPP biennial decommissioning funding status submittals, PG&E would like to clarify the structure of the trust. PG&E maintains a Nuclear Decommissioning Trust, 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 is evaluating the need for a mechanism to separate the total trust balance for each unit into funds accumulated for radiological decommissioning, spent fuel management, and site restoration. This has been entered in the corrective action program for evaluation.

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.

2. The amount accumulated at the end of the calendar *year preceding the date of the report for items included in 10 CFR 50.75 (b) and (c). The values below represent the total amountaccumulated for decommissioning and includes funds for radiological decommissioning, spent fuel management, and site restoration.

As indicated in the cover letter, PG&E is evaluating the need for mechanism to a separate the total trust balance for each unit into funds accumulated for radiological decommissioning, spent fuel management, and site restoration. This has been entered in the corrective action program for evaluation. (Alternatively, the total amount accumulated at the end of the calendar year preceding the date of the report can be reported here if the cover letter transmitting the report provides the total estimate and indicates what portion of that estimate is for items not included in 10 CFR 50.75 (b) and (c)).

  • Unit 2 $1,708.5
3. A schedule of the annual amounts remaining to be collected include items Qeyond those *required in 10 CFR 50.75 (b) and (c).

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 nonradiological 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 the Department of Energy are not included in the cost formulas.

for lack of a better alternative at this time.

Note (f): Effectlve 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 201 O and 2012 and adding to the 2012 base. ,

Note (i): 201"5 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 (j): 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 tac.tor 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."
