Decommissioning Funding Report for Humboldt Bay Power Plant. Unit 3
Dear Commissioners and Staff:
Pacific Gas and Electric Company (PG&E) is submitting its decommissioning funding report for Humboldt Bay Power Plant (HBPP), Unit 3, pursuant to the requirements of 10 CFR 50. 75(f), 10 CFR 50.82(a)(8)(v), and 10 CFR 50.82(a)(8)(vii).
Humboldt Bay Power Plant. Unit 3 PG&E has spent $745.7 million on NRC radiological decommissioning activities through December 2017. At the end of calendar year 2017, the market value of the HBPP Unit 3 (220 megawatt thermal (MWt)) decommissioning trust fund was
$150.4 million. PG&E estimates that $76.2 million will be needed to complete the NRC radiological scope. PG&E estimates it will need to collect an additional
$123.8 million over two years, beginning in 2018, based on a site-specific decommissioning cost estimate (SSDCE) prepared by PG&E staff and submitted to the California Public Utilities Commission's (CPUC's) 2015 Nuclear Decommissioning Cost Triennial Proceeding (NDCTP) on March 1, 2016. The SSDCE was approved by the CPUC in Decision 17-05-020, dated May 25, 2017 which includes radiological decommissioning, site restoration, and spent fuel management. The cost estimate in the NDCTP application is based on actual bids for remaining HBPP civil work scope and includes radiological decommissioning, such as costs for removal of underground reactor caisson, spent fuel management costs associated with the delay in the Department of Energy's acceptance of site-stored spent fuel, cost to remediate site radioactivity to resident farmer criteria, and updated remaining decommissioning costs based on actual past HBPP decommissioning data versus industry estimates.
The NRC minimum decommissioning estimate is $451.9 million (2018 dollars) that was calculated pursuant to the requirements specified in 10 CFR 50.75(c), which is based on a minimum 1200 MWt plant that has not started decommissioning
Document Control Desk March 27, 2018 Page2 PG&E Letter HBL-18-004 activities. HBPP is approximately 92 percent complete with the radiological decommissioning scope of work and has withdrawn funds through 2017 from the HBPP trust resulting in a current market value lower than the NRC minimum estimate.
PG&E is confident that the HBPP trust, with the noted additional contributions, will be sufficient to ensure successful radiological decommissioning and maintaining the spent fuel in an independent spent fuel storage installation (ISFSI) at HBPP until 2030, based on the March 2016 SSDCE prepared by PG&E staff.
Supporting Cost Estimates Based on a March 2016 site-specific cost estimate prepared by PG&E staff, PG&E estimates that the total HBPP decommissioning costs are approximately
$1,097.9 million (including $745.7 million disbursed from the Trust(s) through December 2017, and $76.2 million future radiological decommissioning costs) for HBPP, Unit 3, in 2018 dollars. These NRC decommissioning costs do not include site restoration ($67.5 million), or spent fuel management unti12030 ($208.5 million).
To assure that sufficient funds will be available for decommissioning, PG&E established external sinking trust fund accounts for HBPP, Unit 3.
Supporting Enclosures Enclosures 1-4 provide supporting documentation for this report. provides decommissioning funding status information in a format suggested by Nuclear Energy Institute (NEI) and the NRC. provides information on the escalation of the required decommissioning funding amounts in 2018 dollars. As required by 10 CFR 50.75(c)(2), the information includes escalation factors for energy, labor, and waste burial costs. was prepared 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 16. provides a cash flow of the total decommissioning of HBPP that identifies the monies for NRC scope (removal of radiological contamination), site restoration (including the nonradiological work) and the spent fuel management. contains the variance of the 2017 forecast of $121.8 million, as submitted in Enclosure 3 of PG&E Letter HBL-17-006, "Decommissioning Funding
Document Control Desk March 27, 2018 Page 3 PG&E Letter HBL-18-004 Report for Humboldt Bay Power Plant, Unit 3," dated March 31, 2017, to the actual expenditures for 2017 of $104.0 million.
PG&E is not including the 2015 site specific cost estimate prepared by PG&E as this document was included in the 2016 Decommissioning Funding Report for Humboldt Bay Power Plant, Unit 3, PG&E letter HBL-16-006, "Decommissioning Funding Report for Humboldt Bay Power Plant, Unit 3," dated March 31, 2016.
PG&E makes no new or revised regulatory commitments (as defined by NEI 99-04) in this letter.

PG&E Letter HBL-18-004 NRC Decommissioning Funding Status Report Humboldt Bay Power Plant - Unit 3 (220 MWt)
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 March 31, 1999, and annually thereafter, on the status of its decommissioning funding for each reactor that it owns and has already closed.
Note that Items 3, 4, and 8 are data included in PG&E's 2015 Nuclear Decommissioning Cost Triennial Proceeding (NDCTP) filed with the California Public Utilities Commission (CPUC) on March 1, 2016; and approved by the CPUC in Decision 17-05-020, dated May 25, 2017, which includes radiological decommissioning, site restoration, and spent fuel management costs.

Note (f) Effective with NUREG-1307, Revision 8 (Ref.3) 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 NUREG1 307, 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) 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 (i) Effective with NUREG-1307, Revision 16, the CWF in Andrews County, Texas, is also available as a full-service (i.e.,
Class A, B, and C) LL W disposal facility for waste generators located in States not affiliated with the Texas Compact. Out-of-compact generators, however, must submit an import petition to the Texas Compact Commission for approval prior to shipping.
The State of Texas also limits total non-compact waste disposed at the CWF to 30-percent of licensed capacity and imposes additional fees on LLW disposed offrom out-of-compact generators. With the availability of this full-service disposal facility to out-of-compact waste generators and the Clive, Utah disposal facility for any Class A LLW generated in the U.S., the Generic LLW Disposal Site option used in previous versions of NUREG-1307 is replaced with this option, which provides Bx values representing a composite of the disposal rates for these two disposal facilities. These Bx factors are recommended for use for plants that currently have no disposal site available within their designated LLW Compact. Accordingly, given this consideration, licensees may want to set aside additional decommissioning trust funds to avoid significant future shortfalls in funding and potential enforcement actions.

Non-NRC related scope, Final Site Restoration delay in invoicing and scope deferred to 2018. Spent Fuel Management delayed work on infrastructure upgrades and the upgrade for the security computer system that was planned in 2017.
