Pacific Gas and Electric Company March 31,2011 PG&E Letter HBL-11-003 U.S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, DC 20555-0001 Docket No. 50-133, OP-DPR-7 Humboldt Bay Power Plant Unit 3 John T. Conway Senior Vice President-Energy Supply &

Chief Nuclear Officer 10 CFR 50.75 Decommissioning Funding Report for Humboldt Bay Power Plant Unit 3

Dear Commissioners and Staff:

77 Beale Street Mail Code B32 San Francisco, CA 94105 415.973.3336 Internal: 223.3336 Fax: 415.973.2313 Alternate Address Diablo Canyon Power Plant

p. O. Box 56 Avila Beach, CA 93424 805.545.3333 Fax: 805.545.4884 PG&E is submitting the decommissioning funding report for Humboldt Bay Power Plant (HBPP) Unit 3, pursuant to the requirements of 10 CFR 50.75(f).

Humboldt Bay Unit 3 At the end of calendar year 2010, the market value of the HBPP Unit 3 (220 MWt) decommissioning trust funds was $313.8 million. PG&E estimates an additional

$69.15 million (future nominal dollars) will need to be collected over three years beginning in 2011 based on a site-specific decommissioning cost estimate prepared by TLG Services, Inc., and approved by the California Public Utilities Commission (CPU C) per Decision 0.10-07-047. The CPUC Application is based on an Independent Spent Fuel Storage Installation (ISFSI) that would be in operation until 2020 when all fuel would be removed from HBPP by the Department of Energy (DOE).

The market value of the HBPP trust, plus actual incurred costs through 2010, is lower than the minimum amount of the NRC decommissioning estimate of

$619.0 million (2011 dollars) that was calculated pursuant to the requirements specified in 10 CFR 50.75(c), which is based on a minimum 1200 MWt plant.

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 ISFS"I at HBPP until 2020 based on a site-specific decommissioning cost estimate prepared by TLG Services, Inc., and approved by the CPUC Decision 0.10-07-047.

Supporting Cost Estimates Based on a site-specific cost estimate prepared by TLG Services, Inc., PG&E has estimated that the decommissioning costs are approximately $555.9 million (including

$127.0 million disbursed from the Trust(s) through December 2010 and $317.6 million future radiological removal costs) for HBPP Unit 3 in 2010 dollars. These costs do not include site restoration of the facilities ($2.0 million), nor spent fuel management until 2020 ($109.3 million).

Document Control Desk March 31,2011 Page 2 PG&E Letter HBL-11-003 To assure that sufficient funds will be available for decommissioning, PG&E has established external sinking trust fund accounts for HBPP Unit 3.

Supporting Enclosures Supporting documentation for this report is included as Enclosures 1 through 4. 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 from 1986 dollars to 2010 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 14, the information includes escalation factors for energy, labor, and waste burial costs. is Appendix D from the TLG Services, Inc. decommissioning cost estimate report prepared in March 2009 for PG&E for HBPP Unit 3. The TLG Services, Inc. cost estimate has then been adjusted to reflect the costs in 2011 dollars per the CPUC Decision D.1 0-07 -04 7. The report provides cost estimates for decommissioning of nuclear, non-nuclear facilities, and spent fuel management, including operation of the ISFSI. 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 nonradiological work), and the spent fuel management.

There are no regulatory commitments in this letter.

Should you have any questions in regard to this document please feel free to call Mr. Bob Kapus at (707) 444-0810.

Sincerely,

~

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.

1. The minimum decommissioning fund estimate, pursuant to 10 CFR 50.75(b) and (C).1 January 2011 dollars (HBPP is a shutdown unit with a Site Specific Cost Study; therefore, the minimum decommissioning fund estimate is based on the Site Specific Cost Study shown in item 8 of this enclosure.)

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). (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)).

Market Value (December 201 0 dollars)

3. A schedule of the annual amounts remaining to be collected for items in 10 CFR 50.75(b) and (c). (Alternatively, the annual amounts remaining to be collected can include items beyond those required in 10 CFR 50.75(b) and (c) if the cover letter transmitting the report provides a total cost estimate and indicates what portion of that estimate is for items that are not included in 10 CFR 50.75(b) and (c)). All values below are from 2009 Nuclear Decommissioning Cost Triennial Proceeding (NDCTP) filing, Final Decision D.10-07-047.

• 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 transfers to Department of Energy are not included in the cost formulas.
