Docket No. 50-133, DPR-7 Humboldt Bay Power Plant, Unit 3 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 (8) (v), and 10 CFR 50.82 (8) (vii).

Humboldt Bay Unit 3 At the end of calendar year 2013, the market value of the HBPP Unit 3 (220 MWt) decommissioning trust funds was $191.5 million. PG&E estimates it will need to collect an additional $384.1 million over four years, beginning in 2014, based on a site-specific decommissioning cost estimate prepared by PG&E staff and approved by the California Public Utilities Commission's Final Decision D.14-02-24 Nuclear Decommissioning Cost Triennial Proceeding (NDCTP). The NDCTP application is based on actual bids foK remaining HBPP civil work scope, costs for removal of underground reactor caisson, cost associated with a delay in the Department of Energy's acceptance of site-stored spent fuel, cost to remediate site radioactivity to nuclear resident farmer criteria, and updated remaining decommissioning costs based on actual past HBPP decommissioning data versus industry estimates.

The market value of the HBPP trust is lower than the minimum amount of the NRC decommissioning estimate of $714.3 million (2014 dollars) that was calculated pursuant to the requirements specified in 10 CFR 50.75(c), which is based on a minimum 1200 MWt plant. This is due to $363.0 million having been spent on NRC decommissioning activities through December 2013, and an estimate to complete of

$520.6 million for the NRC radiological scope.

PG&E is confident the HBPP trust, with the noted additional contributions, will be sufficient to ensure successful decommissioning and maintaining the spent fuel in an independent spent fuel storage installation (ISFSI) at HBPP until 2025, based on the December 2012 site-specific decommissioning cost estimate prepared by PG&E staff.

J

Document Control Desk PG&E Letter HBL-14-009 March 28, 2014 Page 2 Supporting Cost Estimates" Based on a December 2012 site-specific costestimate prepared by PG&E staff, PG&E estimates that the NRC decommissioning costs are approximately $883.6 million (including $363.0 million disbursed from the Trust(s) through December 2013'and

$520.6 million future radiological removal costs) for HBPP, Unit 3, in 2014 dollars.

These costs do not include site restoration ($.8 million), or spent fuel management until 2025 ($144.9 million). To assure that sufficient funds will be available for decommissioning, PG&E established external sinking trust fund accounts for HBPP, Unit 3.

Supportingq Enclosures Enclosures 1 through 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 to 2014 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-1 307, "Report on Waste Burial Charges," Revision 15, the information includes escalation factors for energy, labor, and waste burial costs.

Enolbsure 3 is a cash flow of the total decommissioning of HBPP that identifies the monies for NRC scope (removal of radiological contamination), site restoration (including the non-radiological work), and the spent fuel management. contains the Variance of the 2013 forecast of $164,897,911 as submitted in HBL-1 3-003, "Decommissioning Funding Report for Humboldt Bay Power Plant, Unit 3,"

dated April 1, 2013, to the actual expenditures for 2013 of $98,615,488.

The PG&E decommissioning cost estimate report prepared for the 2012 NDCTP filing for HBPP, Unit 3, which provides cost estimates for the decommissioning of the nuclear, non-nuclear facilities, and spent fuel management, including operation of the ISFSI in 2011 dollars is not included in this submittal. This document was included in the PG&E Letter HBL-13-003.

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. Bob Kapus at (707) 444-0810.

V PG&E Letter HBL-14-009 Page 1 of 2 NRC Decommissioning Funding Status Report Humboldt Bay Power Plant - Unit 3 (22Q,;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.

On December 12, 2012, Pacific Gas & Electric (PG&E) submitted the 2012 Nuclear Decommissioning Cost Triennial Proceeding (NDCTP) to the California Public Utilities Commission (CPUC) for the remaining scope of work to complete the decommissioning of the radiological scope, the non-radiological scope, and spent fuel management of Humboldt Bay Power Plant (HBPP), Unit 3, in the amount of $727.6 million in 2011 dollars. On February 27, 2014, the CPUC issued Phase 1 Decision D.14-02-24 that approved the remaining scope of work however reduced the funding by $47.2 million in 2011 dollars. There was no specificity identified by the CPUC of the scope related to this $47.2 million reduction, this funding was not a disallowance, and therefore can be recovered in PG&E's 2015 NDCTP filing if found to be prudent. The collection of funding (Item 3) is based on the reduced remaining funding of $680.4 million per the CPUC Decision, using the escalation and rate of return assumptions included in the December 12, 2012, NDCTP filing. PG&E anticipates the Phase 2 decision from the CPUC in late 2014 that will include the escalation and rate of return factors to be used in the financial collection analysis. The Phase 2 decision may have an impact in the values shown in Items 3, 4, and 8, which will be reflected in the 2015 Assurance of Funding letter.

Note (t) 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 NUREG1307, Revision 15, the nomenclature forthe two disposal options, referred to as "Direct Disposal" and "Direct Disposal with Vendors" in previous revisions of NUREG-1367, is changed to "Compact-Affiliated Disposal Facility Only" and "Combination of Comapct-Affiliated and Non-Compact Disposal Facilities" to better describe the options.

2013 has no information in NUREG-1 307 Rev 15. 2013 is an estimate that is calculated by applying the average % change between 2010 and 2012 and adding to the 2012 base.
