MILLSTONE POWER STATION UNIT 1 DECOMMISSIONING TRUST FUND DISBURSEMENT THIRTY-DAY WRITTEN NOTIFICATION 51I Dominion
- iiiii' Energy Serial No.
25-230 NRA/NDM:
RO Docket No.: 50-245 License No.: DPR-21 Pursuant to License Condition 2.C(6)(c) of the Millstone Power Station Unit 1 (MPS1)
Facility Operating License, the Decommissioning Trust Agreements for MPS1 include requirements for written notice to the Nuclear Regulatory Commission (NRC) related to payments or disbursements from the decommissioning trust fund. Specifically, written notice must be made to the Director, Office of Nuclear Reactor Regulation, at least 30 days before the Trustee makes payments or disbursement, other than for ordinary administrative expenses from the decommissioning trust fund. The Decommissioning Trust Agreements further require that no payments or disbursements be made from the decommissioning trust fund if prior written notice of objection is received from the NRC.
The decommissioning activities accomplished to date have placed MPS1 into a long-term modified SAFSTOR condition. Activities required during modified SAFSTOR dormancy include wet spent fuel storage and monitoring, preventive and corrective maintenance on remaining active operating systems, general building maintenance, routine radiological inspections, security, etc. In addition to the costs of the various monitoring and maintenance activities, applicable property taxes, insurance, electricity, and NRC fees are included in these annual costs.
The projected annual costs for modified SAFSTOR and spent fuel management will be approximately $8.3 million in 2026, $8.3 million in 2027, $8.3 million in 2028, $8.3 million in 2029 and $8.3 million in 2030 (in 2025 dollars), and are assumed to escalate by approximately 2.37% per year during this period (representing the average expected Consumer Price Index (CPI) rate over the five-year period). The decommissioning funding analysis for MPS1 submitted on March 26, 2025 (ADAMS Accession No. ML25254A223) demonstrated that the MPS 1 decommissioning trust fund is adequate to complete
Serial No.: 25-230 Docket No.: 50-245 Page 2 of 3 decommissioning (with over $350 million in 2025 dollars remaining in the fund upon completion). The MPS1 decommissioning funding analysis includes spent fuel storage and greenfield restoration costs, which are included in the site-specific cost estimate on which the analysis is based. Consequently, a certain portion of the proposed disbursements related to spent fuel storage proposed disbursements are less than expenditures in the MPS1 funding analysis, but the variance is small compared to the projected excess and does not have a material effect on the funding analysis. The proposed disbursements will not reduce the decommissioning trust fund below levels required for completion of decommissioning.
This letter provides the required written notice pursuant to License Condition 2.C(6)(c) of the MPS1 Facility Operating License and by Section 4.01 of the MPS1 Trust Agreements, for the period from the date of this submittal through the end of 2030. Dominion Energy Nuclear Connecticut, Inc. (DENC) intends to provide written direction to the Trustee with respect to the disbursement of funds no sooner than 30 days from the date of this letter, unless DENC or the Trustee receives written notice of objection from the NRC. Such prior written notice should be directed to:
