YANKEE ATOMIC ELECTRIC COMPANY Telephone (413) 424-5261 49 Yankee Road, Rowe, Massachusetts 01367 CANIKE]EE December 17, 2012 BYR 2012-043 10 CFR 72.4 and 10 CFR 72.30 10 CFR 50.4 and 10 CFR 50.82 ATTN: Document Control Desk Director, Division of Spent Fuel Storage and Transportation Office of Nuclear Material Safety and Safeguards U.S. Nuclear Regulatory Commission Washington, DC 20555 - 0001 Yankee Atomic Electric Company Yankee Rowe Independent Spent Fuel Storage Installation NRC License No. DPR-3 (NRC Docket Nos.50-029 and 72-31)

Subject:

Independent Spent Fuel Storage Installation Decommissioning Funding Plan On June, 17, 2011, the U.S. Nuclear Regulatory Commission (NRC) published a final rule that amended its regulations regarding decommissioning planning, including changes to the information required to be contained in a licensee's decommissioning cost estimate (DCE) and the financial assurance requirements for Independent Spent Fuel Storage Installation (ISFSI) decommissioning funding. In accordance with 10 CFR 72.3 0(b), Yankee Atomic Electric Company (YAEC) is providing to the NRC for review and approval a decommissioning funding plan for the Yankee Rowe ISFSI. In the final rule, 10 CFR 50.82(a)(4)(i) was revised to include a requirement to incorporate a cost estimate for the management of irradiated fuel. To satisfy this new requirement, YAEC is providing a cost estimate for the costs of managing irradiated fuel and Greater than Class C (GTCC) waste.

YAEC complies with the requirements of 10 CFR 72.30(b)(1) through (b)(6), as follows.

10 CFR 72.30(b)(1) requires the licensee to provide "information on how reasonable assurance will be provided that funds will be available to decommission the ISFSI." In addition, 10 CFR 72.30(b)(4) requires the licensee to provide a description of the method of assuring funds for decommissioning from 10 CFR 72.30(e), including means for adjusting cost estimates and associated funding levels periodically over the life of the facility. YAEC has established an account within its Nuclear Decommissioning Trust (NDT) entitled, "ISFSI Radiological Decom," that segregates the funds for decommissioning of the ISFSI from the larger balance of funds for ongoing management of irradiated fuel and GTCC waste held in the NDT. Currently, the trust has sufficient funds to meet the revised DCE for the Yankee Rowe ISFSI. In addition, the Decommissioning Funding Assurance Status Report for the Yankee Rowe ISFSI submitted on March 27, 2012, established a schedule for collecting additional funds for calendar years 2012 through 2014. YAEC is currently collecting funds through its power contracts and amendatory agreements under Federal Energy Regulatory Commission (FERC) regulations. The power contracts and the amendatory agreements specify the obligations of the purchasers for the costs of Yankee Rowe, including the cost of decommissioning and the costs for management of irradiated fuel and GTCC waste. Such contracts have been filed with FERC.

Yankee Atomic Electric Company BYR 2012-043 December 17, 2012 Page 2 YAEC will periodically reassess the decommissioning cost estimate in accordance with 10 CFR 72.30(c).

On a periodic basis, YAEC will submit rate cases to FERC that will include revised cost estimates for decommissioning and the management of irradiated fuel and GTCC waste. If necessary, additional funds may be recovered from the purchasers.

Also, YAEC successfully litigated the first of what will likely be several breach of contract damages claims against the Department of Energy (DOE) for failure to begin the removal of spent nuclear fuel (SNF) and GTCC waste from the site in 1998. The final appeal opportunity for the government to challenge the award of damages to YAEC in its first damages claim expired on December 4, 2012. A demand for payment to YAEC was submitted by the Department of Justice (DOJ) to the U.S. Treasury on November 26, 2012. YAEC has not yet received that payment. In accordance with YAEC's current FERC Settlement, these proceeds from the damages claim, net of taxes, may be added to the NDT to fund future decommissioning and irradiated fuel and GTCC waste management costs. Additional damages claims against the DOE relating to the government's breach of contract are expected to continue as long as the SNF and GTCC waste remain on site. No credit has been taken for the currently awarded damages or future damages regarding the establishment of funding for the costs associated with decommissioning the YAEC ISFSI or managing irradiated fuel and GTCC waste at the YAEC ISFSI.

10 CFR 72.30(b)(2) requires the licensee to provide a detailed cost estimate for decommissioning. provides a revised DCE for the Yankee Rowe ISFSI that: 1) Assumes an independent contractor will perform the decommissioning activities in accordance with 10 CFR 72.30(b)(2)(i); 2) Includes an adequate contingency factor in accordance with 10 CFR 72.30(b)(2)(ii); and 3) Includes the cost of meeting the criteria for unrestricted release in accordance with 10 CFR 72.30(b)(2)(iii). In addition, the revised Yankee Rowe ISFSI DCE specifically considered the effects of the events described in 10 CFR 72.30(c) on the costs of decommissioning and the extent of contamination. The revised Yankee Rowe ISFSI DCE estimates the costs to decommission the Yankee Rowe ISFSI to be $8.5 million (in 2012 dollars).

10 CFR 72.30(b)(3) requires the licensee to identify and justify the key assumptions contained in the DCE. Enclosure 1 provides the revised DCE for the Yankee Rowe ISFSI, including the key assumptions and the justification for their use.

10 CFR 72.30(b)(5) requires the licensee to define the volume of onsite subsurface material containing residual radioactivity that will require remediation to meet the criteria for license termination. No subsurface material is assumed to require remediation regarding radionuclides. This is justified because:

1) the ISFSI area was confirmed to be clean of radiological contaminants prior to the construction of the ISFSI; 2) the ISFSI area will be maintained clean of loose radiological contaminants during the storage period; 3) the irradiated fuel and GTCC waste are stored in sealed canisters; 4) nuclear activation of the Vertical Concrete Casks (VCCs), VCCs liners, and ISFSI are anticipated; the activation products will remain fixed during the storage period; and 5) if contamination of subsurface occurs during decommissioning activities, the contamination is expected to remain below the decommissioning criteria of 25 millirem per year Total Effective Dose Equivalent.

10 CFR 72.3 0(b)(6) requires a certification that financial assurance for decommissioning has been provided in the amount of the cost estimate for decommissioning. Enclosure 2 provides the certification of financial assurance.

In the final rule published on June 17, 2011, 10 CFR 50.82(a)(4)(i) was revised to include a requirement to incorporate a cost estimate for the management of irradiated fuel. To satisfy this new requirement,

Yankee Atomic Electric Company BYR 2012-043 December 17, 2012 Page 3 provides an estimate of the total costs associated with the Yankee Rowe ISFSI, including the FERC approved cost estimate for the management of irradiated fuel and GTCC waste at the Yankee Rowe ISFSI through calendar year 2022. It estimates the cost to manage the irradiated fuel and GTCC waste at the Yankee Rowe ISFSI to be $66.6 million (in 2013 dollars).

In accordance with 10 CFR 50.82(a)(4)(i), the revised DCE and the cost estimate for the management of irradiated fuel and GTCC waste at the Yankee Rowe ISFSI will be incorporated into the Post-Shutdown Decommissioning Activities Report (PSDAR) following NRC approval. In addition, YAEC is planning to submit a revised cost estimate for management of the irradiated fuel and GTCC waste at the Yankee Rowe ISFSI to FERC that will propose to extend the duration of storage of irradiated fuel and GTCC waste. Following FERC approval, the revised cost estimate and schedule for managing irradiated fuel and GTCC waste will be submitted to the NRC in accordance with 10 CFR 50.82(a)(7).

In March 2013, YAEC will meet the obligations defined in: 1) 10 CFR 50.75(f)(2) regarding the annual Decommissioning Funding Status Report; 2) 10 CFR 50.82(a)(8)(v) regarding a financial assurance status report of decommissioning funding; and 3) 10 CFR 50.82(a)(8)(vii) regarding the status of the funding for managing irradiated fuel.
