Subject:

Decommissioning Funding Assurance Status Report On February 26, 1992, Yankee Atomic Electric Company (YAEC) informed the NRC that the Board of Directors of YAEC had decided to permanently cease operations at the Yankee Nuclear Power Station and that fuel had been permanently removed from the reactor (Reference 1). In accordance with 10 CFR 50.82(a)(2), the certifications in the letter modified the YAEC license t6 perman~~tly ~ithdraw YAEC's authority to operate the reactor. In 1993, Y AEC commenced decommissioning the power plant. On August 10, 2007, the NRC released most of the formerly licensed land'for unrestricted use~ shrinking the licensed land to the Independent Spent Fuel Storage Installation (ISFSI) only (Reference 2). The only decommissioning activities that remain are those associated with the decommissioning of the Yankee Nuclear Power Station ISFSI, which is currently scheduled to occur after the Department of Energy (DOE) removes the irradiated fuel and Greater than Class C (GTCC) waste.

In Attachment 1, YAEC provides the attached Decommissioning Funding Assurance Status Report for the Yankee Nuclear Power Station ISFSI to comply with 10 CFR 50.75(+/-)(1) and (2) and 10 CFR 50:82(a)(8)(v) and (vi}. .., ** '*

1. The amount of decommissioning ~$6.1 million 10 CFR 50.75(c) provides the calculation basis for determining minimum amounts of funds estimated to be required (in 2022 funding required to demonstrate reasonable assurance of funds for decommissioning.

On August 10, 2007, the NRC released most of the formerly licensed land for unrestricted use, shrinking the licensed land to the Independent Fuel Storage Installation (ISFSI). Thus, the only decommissioning activities and decommissioning funding requirements that remain are those associated with the decommissioning of the Yankee Nuclear Power Station ISFSI, which is currently scheduled to occur after the Department of Energy (DOE) removes the irradiated fuel and Greater than Class C (GTCC) waste.

On December 10, 2021, Yankee Atomic Electric Company (YAEC) provided a three-year update to the decommissioning funding plan for the Yankee Nuclear Power Station ISFSI in accordance with 10 CFR 72.30(c) that included a revised Decommissioning Cost Estimate (DCE) for the Yankee Nuclear Power Station ISFSI.

On August 10, 2007, decommissioning, both: the NRC released most of the formerly licensed land for unrestricted use, shrinking the licensed land to the ISFSI.

Over the previous calendar year $0 10 CFR 50.82(a)(8)(v) became effective on December 17, 2012. At that time, the only areas that were within the control of the Operating License No. DPR-3 were those associated with the Yankee Nuclear Power Station ISFSI. Thus, YAEC is only presenting the information associated with the decommissioning of the areas that remain within the control of Operating License No. DPR-3.

Presently, YAEC is storing irradiated fuel and GTCC waste on site until it is removed by the DOE. Decommissioning of the Yankee Nuclear Power Station ISFSI is currently scheduled to be completed in calendar year 203 8, after the DOE removes the irradiated fuel and GTCC waste. Thus, the cumulative cost spent on decommissioning the Yankee Nuclear Power Station ISFSI is $0, and the amount spent in calendar year 2022 is $0.

2. The remaining balance of any ~$22.5 YAEC has established an account within its NDT entitled "ISFSI Radiological Decom" decommissioning funds. million (as of that segregates the funds for radiological decommissioning of the ISFSI from the larger 12/31/2022) balance of funds for ongoing management_ of irradiated fuel and GTCC waste held in the NDT.

The amount provided by other $0 As of December 31, 2022, YAEC's NDT account entitled "ISFSI Radiological Decom" financial assurance methods being has a balance more than sufficient to cover the estimated cost of the remaining relied upon radiological decommissioning of the ISFSI. However, if in the future, the balance in the account is not fully funded to cover the estimated cost of the remaining radiological decommissioning of the ISFSI, the Company has several methods of obtaining additional funds, ifrequired, to cover projected costs.

First, YAEC may collect funds through its power contracts and amendatory agreements under FERC regulation. The power contracts and the amendatory agreements specify the obligations of the purchasers for the costs ofYAEC, including decommissioning.

Pursuant to these power contracts, Y AEC has the ongoing ability to seek collections from its purchasers for additional funds that may be required to cover these costs.

Second, YAEC has received proceeds from the successful litigation of several phases of its breach of contract damages claims against the DOE for failure to begin the removal of spent nuclear fuel (SNF) and GTCC waste from the site in 1998. YAEC will continue to file claims against the DOE as long as the DOE continues to breach its contract obligations related to SNF and GTCC waste.

A YAEC FERC filing approved in June 2013, implemented a fifteen-year funding mechanism. Until the 2013 FERC filing, the Company had employed a "full funding" assumption in developing funding requirements. The fifteen-year funding mechanism was put in place to incorporate the potential for the receipt of future DOE breach of contract damages as a source of funding as discussed below. If future damage recovery does not occur, the Company has the ability to apply to FERC for more funding, if necessary. The approved FERC filing also requires YAEC to provide an informational filing regarding the adequacy of funding if five years pass without receipt of damage awards from litigation with the DOE.

Third, YAEC expects to utilize the investment return on Decommissioning Trust assets as a funding source. The current assumed rate of investment return, after fees and taxes, is 4.0%.
