Subject:
Submittal of the Decommissioning Funding Status Report for Perry Nuclear Power Plant
Dear Sir or Madam:
In accordance with 10 CFR 50.75, "Reporting and recordkeeping for decommissioning planning,"
paragraph (f)(l), Vistra Operations Company LLC, on behalf of Energy Harbor Nuclear Generation LLC, is submitting the decommissioning funding status report for the Perry Nuclear Power Plant (PNPP) for the year ending December 31, 2023. The report is attached.
In accordance with 10 CFR 50.75(b), the estimated cost of decommissioning may be based on either the NRC minimum formula cost amount calculated in accordance with 10 CFR 50.75(c) or a site-specific decommissioning cost estimate (DCE) in accordance with 10 CFR 50.75(b)(4). The PNPP decommissioning funding status report meets the minimum funding criteria based on the use of the site-specific DCE provided by letter dated March 31, 2023 (Accession No. ML23090A233) escalated to 2023 dollars. This report is based on a period of safe storage (SAFSTOR) described in the estimate. Annual cash flows based on this DCE are included in the decommissioning funding analysis report.
Since a final determination on the decommissioning approach has not been made and a different option ultimately may be chosen, Vistra Operations Company LLC recognizes that the chosen option must meet NRC requirements for decommissioning funding assurance.
There are no regulatory commitments contained in this submittal. If there are any questions, or if additional information is required, please contact Jack C. Hicks at (254) 897-6725 or jack.hicks@vistracorp.com.
Sincerely,
Perry Nuclear Power Plant L-24-057 Page 2 of2

Attachment L-24-057 ENERGY HARBOR NUCLEAR GENERATION LLC PERRY NUCLEAR POWER PLANT, UNIT NO. 1 Decommissioning Funding Status Report December 31, 2023 Page 1 of4 The following notes and assumptions were used in developing the Decommissioning Funding Status Report:
- 1.
Energy Harbor Nuclear Generation LLC has 100% ownership interest in PNPP.
- 2.
Formal decommissioning has not started at PNPP. No disbursement of decommissioning trust funds occurred in 2023 except for ordinary administrative costs.
- 3.
Schedule 1 provides the minimum decommissioning fund estimate, pursuant to 10 CFR 50.75(c).
- 4.
The after-tax amount accumulated in the PNPP external trust funds for radiological decommissioning as of December 31, 2023, is provided in Schedule 1.
- 5.
There are no funds to be collected from the ratepayers.
- 6.
There are no contracts upon which Energy Harbor Nuclear Generation LLC are relying pursuant to 10 CFR 50.75(e)(l)(v).
- 7.
There has been no modification to the current method of providing decommissioning funding assurance since the last submitted report.
- 8.
There have been no material changes to the applicable trust agreement(s) since the last submitted report.
- 9.
Mathematical rounding was performed during the development of the supporting calculations.
- 10. The site-specific cost estimate is based on: Perry Nuclear Power Plant Updated Decommissioning Cost Analysis, January 2023 performed in 2022 dollars escalated to 2023 dollars.
- 11. A site-specific cost estimate for the radiological decommissioning of PNPP utilizing SAFSTOR was performed using the guidance of the Regulatory Guide (RG) 1.159, Revision 2. The facility specific analysis demonstrated the adequacy of decommissioning funding since the results of the SAFSTOR analysis are greater than the estimate calculated pursuant to 10 CFR 50.75(c).
- 12. A 2% annual real rate of return is used through dismantlement.
- 13. PNPP is assumed to shut down in 2026, with license termination by 2086.
- 14. Schedule 2 provides a PNPP analysis that provides cash flows based on the site-specific decommissioning cost estimate that includes the use of SAFSTOR. The analysis is associated with the costs for the radiological decommissioning of the facility in 2023 dollars. The cash flow analysis assumes the yearly expenses are incurred at mid-year.
