MILLSTONE POWER STATION UNIT 1 DECOMMISSIONING FUNDING STATUS REPORT Pursuant to 10 CFR 50.75(f)(1) and 10 CFR 50.82(a)(8)(v)-(vii), Dominion Nuclear Connecticut, Inc. (DNC) is providing this report on the status of decommissioning funding for Millstone Power Station Unit 1 (MPS1). provides the following information for MPS1:

Table I -

Decommissioning Funding Status Report for MPS1 Summary Information as of December 31, 2014 Table II -

Decommissioning Funding Status Report for MPS1 Annual Cash Flow Analysis Starting January 1, 2015 through the End of Decommissioning The following information is provided in support and as part of this filing:

1. The escalation of decommissioning costs from the Cost Study's 2014 dollars to 2015 dollars is 1.09% and is based upon the average of CPI-U rates for that period. The mnemonics are "FCPIU.US, CPI-U Not Seasonally Adjusted (NSA)

All Urban Consumers, All Items US City Average (Index, 1982-84=100, SA)."

2. The escalation of decommissioning costs, shown in Table II "Annual Cash Flow Analysis" with a starting date of January 1, 2015 is held at 0% based on assuming 2% Real Rate of Return.
3. The growth rate on Trust Funds is held at the allowed 2% Real Rate of Return over the escalation rate.
4. No rate regulatory authority citation for MPS Unit 1 is referenced because MPS1 is a merchant unit.
5. There are no contracts upon which DNC is relying under paragraph 10 CFR 50.75(e)(1)(v) and there were no modifications to the current method of providing financial assurance since the last submitted report.
6. There are no annual funding amounts for MPS1.
7. Trust Fund amounts shown in this report are market value and after-tax on realized gains and losses. The Trust Fund balances have not been adjusted for unrealized gain or loss positions not currently taxable.
8. Since the previous annual submittal on March 31, 2014 (Serial No.14-140) for MPS1 there have been no material changes to trust agreements established for nuclear decommissioning.

Projected annual expenditures - see Annual Cash Flow Analysis in Table II Notes: Table I

1) Previous decommissioning expenditures represent the withdrawals from the nuclear decommissioning trusts made by Dominion Nuclear Connecticut, Inc. These expenditures do not include the withdrawals made by the former owners of MPS1.
2) These expenditures include withdrawals for spent fuel management, consistent with DNC's previous notices to the NRC, as well as allowed ordinary administrative costs.
3)

A revised Decommissioning Cost Estimate (DCE) was developed in 2014 for MPS1. The estimate of remaining spent fuel management costs reflects a shift in the delayed planned date on which the Department of Energy is expected to begin accepting spent nuclear fuel.

Serial No.15-099 Docket No.50-245 Page 3 of 3 Millstone Power Station Unit 1 Decommissioning Funding Status Report as of December 31, 2014 Table II Definitions:

Column 1:

Beginning of Year Balance:

Reflects the beginning-of-year Trust Fund balance at a 0.0% cost escalation rate and a 2.0% Real Rate of Return (RRoR) on fund growth.

Column 2:

Earnings on Trust Funds:

Reflects earnings on funds remaining in the trust. A 2.0% RRoR Fund growth rate is used for 2015 through 2071 which reflects the allowed 2.0% RRoR over a 0.0% cost escalation rate. The annual 2.0% RRoR earnings are calculated on the beginning balance plus 50% of the projected annual expenditure for each year.

Column 3:

Remaining License Termination Expenditures:

Reflects the annual License Termination Plan cost portion at a 0.0% escalation rate from the Site Specific Estimate.

Column 4:

Remaining Spent Fuel Management Expenditures:

Reflects the annual Irradiated Fuel Management Plan cost portion at a 0.0% escalation rate from the Site Specific Estimate. This column is intended to provide the report on the status of funding for managing irradiated fuel required by 10 CFR 50.82(a)(8)(vii).

Column 5:

Remaining Site Restoration Expenditures:

Reflects the annual Site Restoration Plan cost portion at a 0.0% escalation rate from the Site Specific Estimate.

Column 6:

Remaining SAFSTOR Expenditures:

Reflects the annual SAFSTOR Decommissioning Plan cost at a 0.0% escalation rate from the Site Specific Cost Estimate.

Column 7:

End of Year Balance:

Reflects the end of year Trust Fund balance after all projected earnings are added and all projected expenditures are deducted for the year specified at a 0.0% escalation rate and a 2.0% RRoR on fund growth.

Tables I and II General Notes:

1) Trust Fund balance reflects market value on December 31, 2014, net of taxes on realized gains and losses.
2)

The 2.0% RRoR is based on the rate allowed by 10 CFR 50.75(e)(1)(i) and 10 CFR 50.82(a)(8)(vi) and not on any order of rate setting authority.

3)

The funding method for providing financial assurance for decommissioning MPS1 remains prepayment. The cash flow analysis in Table II demonstrates that the amounts accumulated in the Trust are sufficient, with credited earnings at a 2.0% RRoR, to cover the estimated cost of radiological decommissioning, spent fuel management and site restoration.

4) A revised Decommissioning Cost Estimate (DCE) was developed in 2014 for MPSI. The estimate of remaining spent fuel management costs reflects a shift in the delayed planned date, on which the Department of Energy is expected to begin accepting spent nuclear fuel.
