Decommissioning funds estimated to be required pursuant to 10 CFR 50.75(b) and (c) are based upon a site-specific decommissioning cost study, Decommissioning Cost Analysis for Thrce Mile lsland Unit 2, dated December 2014, and escalated to 2017 dollars:

NRC License Termination $1,266,093,777

2. The amount accumulated in external trust funds as of December 31 ,2017 .

After Tax Metropolitan Edison Company $387,229,001 Pennsylvania Electric Company 206,095,945 Jersey Central Power & Light Company 241,059.208 FirstEnergy Corp. Consolidated $834,394.154

3. There are no Ionger any funds being collected from the ratepayers.

4. The assumptions used regarding escalation in decommissioning cost, rates of earnings on decommissioning funds, and rates of other factors used in funding projections:

Consolidated Ownership lnterest in Unit 1 00%

Estimated Rate of Escalation in Decommissioning Costs 0.00%

Estimated After-Tax Rate of Return 2.00%

Year of Site Restoration Completion 2053 Three Mile lsland Nuclear Station, Unit 2 transitions from a Post-Defueling Monitored Storage status to decommissioning in 2040.

All cost are based on a site-specific decommissioning cost study, Decommrssronrng Cosf Analysis for Three Mile lsland Unit 2, dated December 2014 (2013 dollars), then escalated to 2017 dollars using an escalation factor of 2.795% as documented in Escalation Analysis for Three Mile lsland Unit 2, dated February 2015.

5. There are no contracts upon which the owners/licensees are relying pursuant to 10 CFR 50.75(eX1Xv).

TMt-18-004 Page 2 of 4

7. There were no amendments to the trust agreements for the above-mentioned owners of Three Mile lsland Nuclear Station, Unit 2.

8. Site-Specific Cost Analysis Assumptions 10 CFR 50.75(eX1Xi), states, in part, that:

A Iicensee that has prepaid funds based on a site-specific estimate under 50.75(b)(1) of this section may take credit for projected earnings on the prepaid decommissioning trust funds, using up to a 2 percent annual real rate of return from the time of future funds' collection through the projected decommissioning period, provided that the site-specific estimate is based on a period of safe storage that is specifically described in the estimate.

ln accordance with Regulatory Guide 1.159, Revision 2, Assuring the Availability of Funds for Decommissioning Nuclear Reacfors, a facility specific analysis may be used to demonstrate the adequacy of decommissioning funds, provided that:

NRC-required cost estimate for decommissioning costs, as defined in 10 CFR 50.2, is equal to or greater than the amount stated in the formulas in 10 CFR 50.75(c)(1) and (2).

The site-specific radiological decommissioning cost estimate is $1,266,093,777 which is greater than the 10 CFR 50.75(c) cost estimate of $486,531,672. The analysis assumes a 2 percent yearly rate of return. The analysis also assumes a period of safe storage. The cash flows were contained in a decommissioning cost estimate that was prepared for Three Mile lsland Nuclear Station, Unit 2. The cash flow analysis assumes the yearly expenses are incurred at the beginning of year.

Schedule 1 provides the site-specific analysis. The analysis values are in 2017 dollars.

The analysis is based on TMI-2 transitioning from Post-Defueling Monitored Storage status to decommissioning in 2040 and includes expenditures for license termination costs only.

9. Mathematical rounding was performed during the development of the supporting calculations.
