MILLSTONE POWER STATION UNIT 1 DECOMMISSIONING FUNDING STATUS REPORT Serial No.

NL&OS/T JS Docket No.

License No.16-107 Rev.a 50-245 DPR-21 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, 2015 Table II - Decommissioning Funding Status Report for MPS1 Annual Cash Flow Analysis Starting January 1, 2016 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 2016 dollars is 0.99% and is based upon the average of CPl-U rates for that period. The mnemonics are "FCPIU.US, CPl-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 is held at 0% based on assuming a 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 MPS1 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 balances 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 that are not currently taxable.

8. Since the previous annual submittal on March 26, 2015 (Serial No.15-099) for MPS1 there have been no material changes to the Trust agreements established for nuclear decommissioning.

Column 7:

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.

Earnings on Trust Funds:

Reflects earnings on funds remaining in the trust. A 2.0% RRoR Fund growth rate is used for 2016 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.

Remaining License Termination Expenditures:

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

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 provides information on the status of funding for managing irradiated fuel as required by 10 CFR 50.82(a)(8)(vii).

Remaining Site Restoration Expenditures:

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

Remaining SAFSTOR Expenditures:

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

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: (Any minor differences in totals are due to rounding.)

1) Trust Fund balance reflects market value on December 31, 2015, 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.

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.

Earnings on Trust Funds:

Reflects earnings on funds remaining in the trust. A 2.0% RRoR Fund growth rate is used for 2016 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.

Remaining License Termination Expenditures:

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

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 provides information on the status of funding for managing irradiated fuel as required by 10 CFR 50.82(a)(8)(vii).

Remaining Site Restoration Expenditures:

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

Remaining SAFSTOR Expenditures:

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

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: (Any minor differences in totals are due to rounding.)

1) Trust Fund balance reflects market value on December 31, 2015, 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.
