Serial No.22-286 NRA/SS Rev. 0 Docket No.
50-245 License No. DPR-21 REVISION TO PREVIOUS THIRTY-DAY WRITTEN NOTIFICATION Pursuant to License Condition 2.C(6)(c) of the Millstone Power Station Unit 1 (MPS1)
Facility Operating License, the Decommissioning Trust Agreement for MPS1 includes 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 of the Office of Nuclear Reactor Regulation at least 30 days before the Trustee makes payments_ or disbursements other than for ordinary administrative expenses from the decommissioning trust fund.
The MPS1 Decommissioning Trust Agreement further requires that no payments or disbursements be made from the decommissioning trust fund if prior written notice of objection is received from the NRC.
On November 30, 2020, Dominion Energy Nuclear Connecticut, Inc. (DENC) submitted a written trust fund disbursement notification (Serial No.20-410, ML20336A104) intended to cover expected, non-administrative expenses for MPS1 for the period from 2021 through 2025. In that submittal, DENC discussed projected annual costs for modified SAFSTOR, spent fuel management and additional activities of "approximately $5.9 million in 2021, $5.3 million in 2022, $6.3 million in 2023, $5.3 million in 2024, and $5.3 million in 2025 (in 2020 dollars)." The higher costs in 2021 were explained as "attributable predominantly to the Turbine Building Crane Main Hook maintenance project. The higher costs in 2023 are attributable predominantly to BADGER testing and removal of the deenergized 345kv transmission line."
As reported in DENC's most recent decommissioning funding status report, dated March 30, 2022 (Serial No.22-048, ML22089A186), the costs for modified SAFSTOR, spent fuel management and additional activities were approximately $4.5 million in 2021.
MPS1 has been experiencing deterioration of building roofs over recent years, thus DENC has determined that two building roofs need replacement. As a result, DENC is updating the projected spending (in 2022 dollars) to approximately $6.5 million in 2022, $8.8 million in 2023, and $5.7 million in 2024 and 2025. These values are assumed to escalate by approximately 3.65% per year (representing the average expected Consumer Price Index rate during the 2022 - 2025 period): The increase in expenditures for 2022 is attributable
Serial No.22-286 Docket No. 50-245 Page 2 of 3
-to the replacement of the Maintenance Garage roof ($0.7 million), and the increase in expenditures for 2023 is attributable to replacement of the Reactor Building roof ($1.9 million).
The MPS1 decommissioning funding analysis, which was provided in Attachment 1 of the decommissioning funding status report submitted on March 30, 2022, demonstrated that the MPS1 decommissioning trust fund is adequate to complete decommissioning (with over $465 million in 2022 dollars remaining in the fund upon completion). The MPS1 decommissioning funding analysis includes spent fuel storage costs, which are included in the site-specific cost estimate on which the analysis is based. The proposed disbursements are greater than the expenditures estimated in the 2022 MPS1 decommissioning funding analysis, but the variance is very 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 Decommissioning Trust Agreement, for the period from the date of this submittal through the end of 2025.
DENC intends to provide written direction to the Trustee with respect to the expenditure 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 both:
