Table I -

Decommissioning Funding Status Report for MPS1 Summary Information as of December 31, 2017 Table II - Decommissioning Funding Status Report for MPS1 Annual Cash Flow Analysis Starting January 1, 2018 through 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 2018 dollars is 1.52% and is based upon the average of CPI-U rates for that pe:riod. The mnemonic is "FCPIU.US CPI: Urban Consumer - All Items, (Index 19182-84=100, SA)."
2. The escalation rate of decommissioning costs, shown in Table II is 0% based on assuming a 2% Real Rate of Return.
3. The growth rate on Trust Funds is the allowed 2% Real Rate of Return over the escalation rate.
4. N~> rate regulatory authority citation for MPS1 is referenced because MPS1 is a m13rchant unit.
5. There are no contracts upon which DENC 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 30, 2017 (Serial No.17-081, ADAMS Accession No. ML17094A518) for MPS1 there have been no material changes to the Trust agreements established for nuclear decommissioning.

Columr1 6:

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 r~rriainiilg in the trusf.

  • A 2.0% RRoR Fund growth rate is used for 2018 through 2071 which reflects the allowed 2.0°/o
  • RRoR over a 0.0%
  • cost escalation rate.

The annual 2.0% RRoR earnings are -calculated on the beginning balance less 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 ~ue to rounding.)

1) Trust Fund balance reflects market value on December 31, 2017, 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).
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 Trnst are sufficient, with credited earnings at a 2.0% RRoR, to cover the estimated cost of rc:1diological decommissioning, spent fuel management and site restoration.
