Enclosure By letter to the U.S. Nuclear Regulatory Commission (NRC) dated October 28, 2009 (Agencywide Documents Access and Management System (ADAMS)
Accession No. ML093020064), Northern States Power Company, a Minnesota corporation (NSPM), doing business as Xcel Energy, submitted a request for review and approval of the Irradiated Fuel Management Plan and Preliminary Decommissioning Cost Estimate for the Prairie Island Nuclear Generating Plant (PINGP), Unit 2.
Following are NRC requests for additional information on Enclosure 1 of the NSPM letter dated October 28,2009 (shown as bold) and the NSPM responses.
(Note: Numbers may not add due to rounding).
RAI No.1: Nuclear Regulatory Commission (NRC) Minimum and Funding Status PINGP Unit 2 reported a trust fund balance of $357.8 million as of July 2009. What is the radiological decommissioning trust fund (DTF) balance as of December 31,2009? What is the impact of the December 31,2009 DTF balance on the October 28,2009 submittal?
NSPM Response:
NSPM letter to the NRC, "Decommissioning Funding Status Reports", dated March 31, 2010, (ADAMS Accession No. MLI 00910135) stated a radiological decommissioning trust fund balance of $385 million as of December 31, 2009.
This demonstrated an increase of approximately $27 million over the radiological balance reported in the October 28, 2009 submittal.
RAI No.2: Sufficiency of Funds Analysis In its submittal, PINGP stated that the Minnesota Public Utilities Commission approved a 2.89 percent cost escalation rate and a 6.30 percent earnings rate on external funds resulting i n a 3.41 percent real rate of return. Xcel submitted, for PINGP on March 31, 2009, the Decommissioning Funding Status Report (L-XE-09-05) that used an earnings rate of 5.4 percent, an escalation factor of 3.61 percent and a real rate of return of 1.79 percent with projected annual continuations of $12.65 million for approximately 6 years. Provide the documentation that supports the higher rate of return, as well as the period for which the 3.41 percent real rate of return applies.
NSPM Response:
Xcel Energy files a triennial decommissioning study with the Minnesota Public Utilities Commission (MPUC) for approval. A portion of the study is dedicated to Page 2 of 13
Enclosure an internal analysis of inflation factors surrounding the various components necessary to perform the decommissioning function. The analysis utilizes long-range inflation projections published by Global Insight, the Consumer Price Index, and the Chained Price Index for Gross Domestic Product, as well as other forecasted data. The rate of earnings and escalation factors were approved by the MPUC in the most recent triennial decommissioning study completed by Xcel Energy, MPUC Docket# E-002lM-08-1201, effective June 12, 2009. The MPUC approval assumes that the 3.41% is a levelized rate of return over the remaining plant operating life along with the entire decommissioning period. This rate will be reviewed again in the next Xcel Energy triennial decommissioning filing with the MPUC, which is required to be filed by October 201 1.
RAI No.3: Sufficiency of Funds Analysis If there are changes in the DTF balance that materially impact the licensee's cost analysis, given these considerations, the licensee would be under an obligation under 10 CFR 50.9 to update any changes in projected cost or available funds. Has PINGP examined the impact of the change in the real rate of return and the deletion of the annual contributions on the projected DTF balance identified in their submittal dated March 31, 2009, and the PINGP Unit 1 submittal dated August 8, 2008?
NSPM Response:
The following tables provide a breakdown of the annual decommissioning costs, total expenditures, and total contributions for radiological, ISFSl (spent fuel management) and site restoration (Greenfield) for each Unit 2 cost area, and Unit 2 cost areas combined. This analysis assumes the current rate of return approved by the MPUC in 2009. In this analysis, the annuity (contributions) for 2010 and 201 1 are collected exclusively from ratepayers in the North Dakota jurisdiction. For the years 2012, 2013 and 2014 the annuity (contributions) will again come from ratepayers in all jurisdictions.
The beginning balances shown are the external fund balances, including both the qualified fund and the escrow fund, as of December 31, 2009. Decommissioning payment values are shown in 2009 dollars, inflated one year from the original decommissioning cost study values, using an assumed rate of inflation of 2.89%.
Assumed interest was calculated using an assumed real rate of return of 3.41%.
The effect of inflating the radiological decommissioning payments (expenditures) one year forward into 2009 dollars is an increase of approximately $15.5 million over the total radiological expenses shown in 2008 dollars in the NSPM letter to the NRC "Supplement to Irradiated Fuel Management Plan and Preliminary Decommissioning Cost Estimates for Prairie Island Nuclear Generating Plant (PINGP) (TAC Nos. MD9492, MD9493, MD9494 and MD9495)", dated
Enclosure January 19, 2009 (ADAMS Accession No. ML090210156). The 2008 estimate also assumed a 5.40% Rate of Return and a 3.61% Escalation Factor with a Real Rate of Return of 1.79%.
The effect of the changes in these assumptions, along with the corresponding changes in contributions (annuities) from customers, results in an increase in the estimated balance remaining in the fund for radiological decommissioning at the conclusion of decommissioning activities of $10.5 million. Under expected conditions the current fund balances for PlNGP Unit 2 are sufficient to cover all estimated decommissioning payments.

Enclosure RAI No.5: Table 3 Funds Analysis Table 3 does not addresslbreakout the expenses identified in the table. Are the paymentslexpenses for both radiological decommissioning and spent fuel storage costs or for radiological decommissioning costs only? The cost associated with spent fuel storage needs to be included in PINGP's analysis for Unit 2. For Unit I, PlNGP estimated that fuel transfer would begin in 2028, with completion of the fuel transfer to the DOE in 2053, and estimated the annual cost associated with dry storage for the period from 2031 to 2053 at $3.3 million. For Unit 2, PINGP's August 8, 2008, submittal estimated an annual cost of $3.3 million for the period from 2014 to 2053; however, these costs were not included in the analysis.
NSPM Response:
Table 3 in the August 8, 2008 submittal provided a breakout of expenses for the various periods involving radiological decommissioning (NRC license termination costs), irradiated fuel management costs, and site restoration costs for each unit.
The tables included in RAI No. 3, above, provide annual cash flows for radiological decommissioning, irradiated fuel management and site restoration costs for Unit 2.
In the August 8, 2008 submittal, the $3.3 million should apply to each year from 2034 to 2053 for Unit 2. The costs associated with irradiated fuel management for years 2014 to 2034 can be calculated as being one half of the cost identified in the IFM [Irradiated Fuel Management] column of Table 1 of the August 2008 report.
RAI No.6: Table 3 Funds Analysis The paymentslexpenditures identified in Table 3 appear to be in 2008 dollars. The expenses are identical to the expenses listed in PINGP's submittal dated January 19, 2009, Table 3.2a, while the trust fund balance is in 2009 dollars. Please update the estimated expenditures to 2009 dollars, and identify the escalation factor and its supporting basis.
NSPM Response:
The following tables show the estimated decommissioning costs for radiological, spent fuel management, and site restoration activities updated to 2009 dollars using the assumed rate of inflation approved by the MPUC in the 2008 triennial nuclear decommissioning filing. These costs tie to the payments shown in the tables in response RAI No. 3. The escalation factor assumed for this purpose is 2.89%.
