Enclosure LIC-17-0031 Page 1 of 11 Fort Calhoun Station Irradiated Fuel Management Plan I. Background and Introduction On August 25, 2016, Omaha Public Power District (OPPD) submitted a letter to the U.S. Nuclear Regulatory Commission (NRC) (Reference 1) certifying the permanent cessation of operations at the Fort Calhoun Station (FCS) effective October 24, 2016, in accordance with 10 CFR 50.82(a)(1 )(i). All fuel was removed from the FCS reactor vessel and placed in the spent fuel pool as certified in accordance with 10 CFR 50.82(a)(1)(ii) (Reference 2).

Pursuant to 10 CFR 50.54(bb), licensees are required to submit a plan for the management of irradiated fuel until title and possession of the fuel is transferred to the Secretary of Energy for its ultimate disposal in a repository. The Irradiated Fuel Management Plan (IFMP) is required to be submitted to the Commission either five years before expiration of the Operating License or within two years following permanent cessation of operations, whichever occurs first. Therefore, the FCS IFMP is required to be submitted prior to October 24, 2018, two years following cessation of operations.

Post-Shutdown Decommissioning Activities Report (PSDAR) and Decommissioning Cost Estimate (DCE) have been prepared and submitted (Reference 3). The DCE identifies the details, schedules, and costs of spent fuel management activities associated with the IFMP, along with license termination and site restoration activities and costs. The assumptions regarding the United States Department of Energy (US DOE) acceptance of irradiated fuel are consistent with the DCE. The FCS DCE and this IFMP are based on commencement of industry-wide acceptance of spent fuel by US DOE in 2030.

II. Irradiated Fuel Management Strategy The safe initial interim storage of FCS irradiated fuel will be a combination of "wet storage" in the FCS spent fuel pool and "dry storage" in the FCS Independent Spent Fuel Storage Installation (ISFSI). While spent fuel is stored in the spent fuel pool, spent fuel storage and handling systems will be maintained in operation. Following transfer of all spent fuel from the spent fuel pool to the FCS ISFSI, spent fuel storage and handling systems will be removed from operation.

A total of 1,264 irradiated fuel assemblies have been generated at FCS. At present, 320 irradiated fuel assemblies have already been transferred to the FCS ISFSI. The remaining 944 irradiated fuel assemblies will be loaded in dry fuel canisters and transferred to the ISFSI.

The current ISFSI is located inside the Owner Controlled Area. It was designed and constructed to accommodate all FCS irradiated fuel. The ISFSI currently contains 10 dry fuel canisters storing FCS fuel. All of the fuel on the ISFSI is stored in Trans nuclear NUHOMS Model Number-32PT Dry Shielded Canisters.

The major IFMP activity phases, including start dates, end dates and associated costs for each period are identified in Table 1. The identified Decommissioning Periods are developed in and align with the site-specific DCE.

Enclosure LIC-17-0031 Page 2 of 11 The current plan is to commence the movement of the irradiated fuel from the FCS spent fuel pool to the FCS ISFSI in 2021. OPPD expects to complete the transfer in 2022. Additional dry fuel canisters will be procured from one or more of the available dry storage system suppliers beginning in 2018. It is anticipated that an additional30 dry fuel canisters will be required for the remaining FCS irradiated fuel (dependent on the capacity of the selected system).

The US DOE Standard Contracts for acceptance and disposal of nuclear fuel and high level waste contain the basis for initial ranking of industry-wide spent fuel acceptance obligations based upon the date of permanent removal of the spent nuclear fuel from service ("oldest fuel first" allocation). Those Standard Contracts also contain provisions allowing for "exchanges" of acceptance obligations, and priority for retired units. Given the US DOE's lack of a performance plan, a common assumption for purposes of this fuel management plan is to base acceptance projections upon application of an "oldest fuel first" allocation scheme to a projected start date for repository operations. This plan is based upon a 2030 start date for US DOE acceptance of spent fuel from the industry and the FCS position in the queue. As indicated in Table 2, OPPD is therefore assuming all spent fuel will be removed from the FCS site as of 2058. Based on this information, the ISFSI will be subsequently decommissioned by the 2065 final license termination date.

Ill. Financial Assurance The site-specific decommissioning cost analysis prepared by TLG Services, Inc. projects the total cost of Spent Fuel Management activities to be $405.5 million in 2016 dollars as shown in Table 3. The FCS DCE contains an estimate of the costs of license termination, spent fuel management, and site restoration. Tables 3.2a, 3.2b, and 3.2c in the DCE delineate the annual expenditures for license termination, spent fuel management, and site restoration respectively.

This annual expenditure information is used in the cash flow analysis. The purpose of the cash flow analysis (Table 4) is to demonstrate that the balance in the FCS Decommissioning Trust Fund (DTF) is sufficient to cover license termination expenses.

Under NRC regulations (1 0 CFR 50.82(a)(8)), a licensee must provide reasonable assurance that funds will be available (or "financial assurance") for decommissioning (i.e., license termination) costs. The regulations also describe the acceptable methods a licensee can use to demonstrate financial assurance. Most licensees do this by funding a nuclear decommissioning trust (NDT). Nebraska State Statues provides the regulatory authority that allows OPPD's Board of Directors to establish the inflation rates and earning rates of OPPD.

OPPD maintains two separate trust accounts for this purpose, one for the License Termination Expenditures (NRC minimum decommissioning amount) and another for the Spent Fuel Management and Site Restoration Expenditures. As of December 31, 2016, the License Termination Expenditures trust had a balance of $285,838,000 and the Spent Fuel Management and Site Restoration Expenditures trust had a balance of $96,296,000.

The two trust funds are not commingled and the funds accumulated for the additional decommissioning cost are not included as funds for the NRC minimum decommissioning amount. The funds accumulated for the additional decommissioning costs including additional radiological, site restoration and spent fuel management are available for radiological decommissioning without prior approval by a State regulatory authority and are not subject to disapproval for radiological decommissioning by a State regulatory authority.

Enclosure LIC-17-0031 Page 3 of 11 Costs are inflated using a blending of the IHS Global Insight's forecasts for Consumer Price Index, All-Urban and Employment Cost Index, Total Private Compensation. The indices are blended based on the ratio of labor and all other costs to the total DCE. For the years beyond the available forecast, the final forecast rate available is held constant for the duration of the analysis.

Consistent with Regulatory Guide 1.159, OPPD will update the FCS DCE as required. In calculating projected earnings, OPPD uses the IHS Global Insight's forecast for the yield on 5-year Treasury Notes which is within a two percent (2%) annual real rate of return. The rates used for the escalation of the site-specific decommissioning cost estimate and earnings rates on the Decommissioning Fund through the completion of decommissioning are shown in Table 5.

OPPD intends to fund the cost of decommissioning (license termination, spent fuel management and site restoration) out of existing operations until the DTF is funded in the 2022 timeframe, as currently forecasted. When the remaining cost of decommissioning matches the funding in the DTF then OPPD will withdraw any decommissioning expenses from the DTF.

In the event that additional financial assurance beyond the amounts contained in the remaining trust fund for FCS is required pursuant to NRC regulations to complete radiological decommissioning and spent fuel management at FCS, OPPD will augment the NDTs with annual contributions to the NDTs.

As conditions may change, OPPD will adjust the funding, as appropriate, using alternative funding mechanisms acceptable to the NRC.

IV. Regulatory Activities This spent fuel management plan assumes withdrawals from the supplemental decommissioning trust for spent fuel management purposes.

In accordance with 10 CFR 50.82(a)(8)(vii), OPPD will annually submit to the NRC by March 31 51 a report on the status of the funding for managing spent fuel. The report will include, current through the end of the previous calendar year, the amount of funds accumulated to cover the cost of managing the spent fuel, the projected cost of managing spent fuel until title to the fuel possession is transferred to the Secretary of Energy, and a plan to provide additional funding assurance using one of the methods allowed by the NRC regulations.

V. Summary The spent fuel management activities described in this Irradiated Fuel Management Plan must be performed in conjunction with license termination activities. The cash flow analysis demonstrates that the FCS DTF and the supplemental fund with projected earnings augmented by funding from operations is sufficient to cover the estimated costs of Licensing Termination Expenses, Spent Fuel Management, and Site Restoration.
