Title 10 CFR 50.75(f)(1) requires that each power reactor licensee report to the U.S. Nuclear Regulatory Commission (NRC) at least once every two years on the status of its decommissioning funding for each reactor or part of a reactor that it owns. Pursuant to this requirement, this letter forwards the 2013 Decommissioning Funding Status Report (which reports the funding status as of December 31, 2012) for Calvert Cliffs Nuclear Power Plant (CCNPP), Nine Mile Point Nuclear Station (NMPNS), and R.E.

Ginna Nuclear Power Plant (Ginna). Ginna, CCNPP and NMPNS Unit 1 (NMP1) are wholly owned subsidiaries of Constellation Energy Nuclear Group, LLC (CENG). Nine Mile Point Nuclear Station Unit 2 (NMP2) is co-owned 82% by a wholly owned subsidiary of CENG and 18% by Long Island Power Authority (LIPA).

The information provided in this letter for NMIP2 includes summary statements provided and verified by LIPA.

Document Control Desk March 27, 2013 Page 2 The information required by 10 CFR 50.75(f)(1) is provided in Attachment (1), which contains a table and explanatory notes for each site, with the NRC Minimum amounts calculated based upon the labor, energy, and burial cost escalation factor guidelines in NUREG-1307, Revision 15, issued in January 2013. Financial assurance for radiological decommissioning to allow for license termination for each unit is demonstrated by the use of site-specific nuclear decommissioning cost studies in lieu of the NRC Minimum amounts.

Reference (a) contains the nuclear decommissioning cost study for CCNPP.

Reference (b) contains the nuclear decommissioning cost studies for NMPNS and Ginna. Each of these nuclear decommissioning cost studies (collectively, the Cost Studies) presents decommissioning cost estimates (DCEs) under an immediate decontamination (prompt DECON) Scenario 1 and a delayed DECON (SAFSTOR) Scenario 3.

The Cost Studies are in 2009 dollars. The DCEs are escalated from 2009 dollars to December 31, 2012 dollars based on the rates of increase in the NRC Minimum amounts for the respective units from December 31, 2008 to December 31, 2012. That period approximates the period from the Cost Studies, which reflect 2009 dollars, to December 31, 2012. Further, in order to reflect a consistent rate of cost escalation, the calculated escalation factors exclude the effect of unit uprates authorized during that period. Attachment (5) calculates the rates of increase in the NRC Minimum during that period, and it includes the calculation of the NRC Minimum amount for each unit as of December 31, 2008 using the unit's total megawatt thermal rating as of December 31, 2012.

10 CFR 50.75(b)(1) requires that the DCEs be greater than the NRC Minimum amounts if they are to be relied on for decommissioning funding assurance. The NRC Minimum amounts as of December 31, 2012 are calculated in Attachment (2). As shown in Attachment (3), the DCEs based on the Scenario 1 prompt DECON assumptions in the Cost Studies, with the DCEs escalated to December 31, 2012 dollars, are greater than the NRC Minimum amounts.

The demonstration of financial assurance for the radiological decommissioning of each unit is based on the Scenario 3 SAFSTOR assumptions in the Cost Studies, with costs escalated to December 31, 2012 dollars. Attachment (4) presents the annual escalated DCEs, the annual earnings at an assumed 2% real rate of return on the funds, and the annual fund balances available to provide for the radiological decommissioning of the units following a period of SAFSTOR, pursuant to 10 CFR 50.75(c) and (e). The positive balances of the trust funds throughout the decommissioning periods confirm adequate financial assurance for each of the units because the respective nuclear decommissioning trust funds are sufficient to provide for the radiological decommissioning of the units.

The amounts accumulated as of December 31, 2012 in the external decommissioning trusts include not only funds for the radiological decommissioning of the units, but also funds allocated (the Allocated ISFSI Amounts) for the radiological decommissioning of the sites' independent spent fuel storage installations (ISFSIs).

Pursuant to 10 CFR 50.75 (b) and (c), only the funds for the radiological decommissioning of the units (and not any of the Allocated ISFSI Amounts) are included in the amounts used in the demonstration of financial assurance in Attachment (4). For consistency in approach and presentation with the ISFSI decommissioning funding plan submitted in Reference (c), the Allocated ISFSI Amounts are presented in separate ISFSI columns within Attachment (4). The Allocated ISFSI Amounts as of December 31, 2012 are the present values of funds necessary to provide for the radiological decommissioning of the ISFSIs.

The DCEs and funding measures described herein are presented solely to demonstrate the adequacy of radiological decommissioning financial assurance under NRC regulations.

This information is not intended to be used in any other context (see 10 CFR 50.75(a)). Also, a final determination of the ultimate decommissioning approach for each of the units has not been made. Different decommissioning

Document Control Desk March 27, 2013 Page 3 options, with different costs and schedules, which also meet the requirements under 10 CFR 50.75, may be chosen in the future.

There are no new regulatory commitments contained in this letter.

Summary of Funding Status as of December 31, 2012 Table 1 Notes - Calvert Cliffs Nuclear Power Plant The NRC Minimum amounts in Row 1 a are based on the generic NRC Minimum funding calculation specified in 10 CFR 50.75(c)(1), as adjusted in accordance with paragraph 50.75(c)(2) and Revision 15 of NUREG-1307 (January 2013). The Bureau of Labor Statistics (BLS) indices used regarding energy and labor cost factors were taken from the best source available during the preparation of this submittal, which were the indices published as of December 2012 (preliminary for energy and final for labor). The burial cost escalation factors were taken from the NUREG-1307, Revision 15, Table 2-1, PWR Values for Generic LLW Waste Disposal Site Combination of Compact-Affiliated and Non-Compact Facility for the year 2012.

2 The amounts in Rows la, lb, and lc represent decommissioning costs anticipated to be incurred in removing the CCNPP units safely from service and reducing residual radioactivity to levels that permit release of the property for unrestricted use and termination of the license. The costs of managing and storing spent fuel on the site until transfer to the U. S. Department of Energy (DOE),

the costs of dismantling nonradioactive systems and structures, and the costs of performing brownfielding activities are not included in this estimate.

The trust fund balances in Row 2 generally contemplate that common decommissioning costs would be borne primarily by Unit 2, since the common facilities cannot be decommissioned until Unit 2 is decommissioned.

However, the site-specific SAFSTOR nuclear decommissioning cost study referenced in Reference (a) allocated the costs of decommissioning the common facilities substantially evenly between Unit I and Unit 2.

The long-term target rate of return for the fund is approximately 6.5%; however, CENG employs only a 6% rate of return in Row 4 in accordance with the "up to a 2 percent annual real rate of return" limitation set forth in 10 CFR 50.75(e). The weighted average cost escalation value of 4% in Row 4 for all decommissioning costs is based on recent decommissioning cost escalation analyses performed on a CENG fleet-wide basis.

Comparison of Site-Specific Decommissioning Cost Estimates to NRC Minimum Amounts as of December 31, 2012 Constellation Energy Nuclear Group, LLC March 27, 2013

Constellation Energy Nuclear Group (CENG)

Comparison of Site-Specific Decommissioning Cost Estimates to NRC Minimum Amounts as of December 31, 2012 10 CFR 50.75(b)(1) requires that the DCEs be greater than the NRC Minimum amounts. The NRC Minimum amounts as of December 31, 2012 are calculated in Attachment (2). Row A in the table below summarizes the DCEs based on the Scenario 1 prompt DECON assumptions in the Cost Studies. These DCEs are escalated to December 31, 2012 dollars in Row C below, which escalated DCEs are greater than the respective NRC Minimum amounts on Row D below by the amounts on Row E below.

2 The December 3 1, 2012 NRC Minimum amounts are calculated pursuant to NUREG-1307 Revision 15 (January 2013). They reflect the final labor and preliminary energy indices as of December 2012 published by the Bureau of Labor Statistics and the burial cost escalation factors per NUREG-1307 Revision 15 Table 2-1 Values for Generic LLW Waste Disposal Site Combination of Compact-Affiliated and Non-Compact Facility for the year 2012.

Constellation Energy Nuclear Group (CENG)

Funding and Financial Assurance Analysis as of December 31, 2012 The demonstration of financial assurance for the radiological decommissioning of each unit is based on the Scenario 3 SAFSTOR assumptions in the Cost Studies, with costs escalated to December 31, 2012 dollars. Page 2 of this Attachment (4) presents the sum of the annual escalated DCEs in Row D of the table. Pages 3-11 of this Attachment (4) present the annual escalated DCEs, the annual earnings at an assumed 2% real rate of return on the funds, and the annual fund balances available to provide for the radiological decommissioning of the units following a period of SAFSTOR, pursuant to 10 CFR 50.75(c) and (e). The positive balances of the trust funds throughout the decommissioning periods, as presented on pages 3-11 of this Attachment (4), confirms adequate financial assurance for each of the units because the respective nuclear decommissioning trust funds are sufficient to provide for the radiological decommissioning of the units.

Any funds remaining after the completion of radiological decommissioning could be available to pay for spent fuel management and greenfielding decommissioning activities.

2 For NMP2, the December 31, 2012 trust fund balances reflect the respective CENG and LIPA fund balances, the disbursement and NRC minimum amounts reflect the 82%/18% pro rata CENG/LIPA ownerships, the earnings are calculated on the respective trust fund balances less the pro rata disbursements, and the site-specific study reflects the cost of decommisioning 100% of NMP2.

3 Decommissioning disbursements are assumed to be paid as of January I of each year, apply to only license termination radiological decommissioning costs, and do not include any decommissioning costs for spent fuel management or greenfielding.

4 The trust fund balances for CCNPP generally contemplate that common decommissioning costs would be borne primarily by Unit 2, since the common facilities cannot be decommissioned until Unit 2 is decommissioned.

However, the site-specific SAFSTOR nuclear decommissioning cost study referenced in Reference (a) allocated the costs of decommissioning the common facilities substantially evenly between Unit I and Unit 2. As a result, the amount of financial assurance on Row F above is greater for CCNPP2 than for CCNPPI.

Cost Escalations from Site-Specific Decommissioning Costs Estimates to December 31, 2012 Dollars Constellation Energy Nuclear Group, LLC March 27, 2013

. Constellation Energy Nuclear Group (CENG)

Cost Escalations from Site-Specific Decommissioning Cost Estimates to December 31, 2012 Dollars Dollars in Thousands The purpose of this Attachment (5) is to calculate the increases in the NRC Minimum for each site from December 31, 2008 to December 31, 2012, as presented in the table below. These increases are applied as the compound cost escalation factors to the estimated costs in Scenario I and Scenario 3 of the respective Cost Studies (in 2009 dollars) to escalate them to December 31, 2012 dollars. For consistency, since there have been uprates in the MWth of certain units, the 1986 baseline MWth have been adjusted to the MWth as of December 31, 2012 to calculate the NRC Minimum increases absent the effect of the uprates.
