Decommissioning Cost Estimate Study of the Document No. 82A9584 Kewaunee Nuclear Power Plant Revision 0 Addendum No. 001
1.0 INTRODUCTION
This addendum presents an update to the 2006 Decommissioning Cost Estimate Study of the Kewaunee Nuclear Power Plant (Ref. No. 1), hereinafter referred to as the 2006 Cost Study. The Kewaunee Nuclear Power Plant (Kewaunee) is owned by Dominion Energy Kewaunee, Inc.
(DEK).
Specifically, the addendum provides an economic and technical update to Scenario 2 of the 2006 Cost Study which was based on the existing license expiration date of December 21, 2013, a 2017 Yucca Mountain opening date, and prompt dismantlement. This addendum was prepared to assist DEK in fulfilling the requirement for submission of a preliminary decommissioning plan and decommissioning cost estimate in accordance with Title 10 Code of Federal Regulations (CFR) Part 50.75(f)(2). This update of the 2006 Cost Study incorporates an up-to-date assessment of the major factors that could affect decommissioning Kewaunee at the end of the current license. EnergySolutions has incorporated the following revisions to Scenario 2 of the 2006 Cost Study.
- 1. Escalating costs from 2005 to 2008 dollars using aggregate annual escalation rates furnished by DEK.
- 2. Increasing spent fuel management costs to account for the delay in the Yucca Mountain opening date from 2017 to 2020 using a revised spent fuel shipping schedule furnished by DEK.
- 3. Incorporating the cost of establishing interim storage of Class B and C Low-Level Radioactive Waste (LLRW) due to the closure of the Barnwell LLRW Disposal Facility to out-of-compact generators in July 2008.
- 4. Incorporating the transportation and disposal cost of Class B and C operational waste projected by DEK to be accumulated during the period between November 2008 and December 21, 2013.
- 5. Incorporating the cost of placing Class B and C waste generated during decommissioning into environmentally secure reinforced concrete storage modules, and the subsequent removal of these wastes for transportation and disposal following the assumed 2025 opening of a hypothetical Class B and C waste disposal facility.
- 6. Incorporating the cost of demolition and disposal of the Class B and C reinforced concrete storage modules. The storage modules are assumed to be radiologically surveyed for release, but not to require surface decontamination.
- 7. Incorporating the Independent Spent Fuel Storage Installation (ISFSI) Phase 1 as-built and Phase 2 addition design information that was not available at the time of the 2006 Cost Study into the estimated cost of demolishing the ISFSI.

SUMMARY
OF 2006 COST STUDY RESULTS The 2006 Cost Study presented the results of a site-specific Decommissioning Cost Estimate Study for the Dominion Virginia Power (Dominion) Kewaunee Power Station. The study was performed to furnish an estimate, for financial planning purposes, of the costs for (1) decommissioning Kewaunee to the extent required to terminate the plant's operating license per 10 CFR 50.75(c), (2) post-shutdown management of spent fuel until acceptance by the U.S.

Decommissioning Cost Estimate Study of the Document No. 82A9584 Kewaunee Nuclear Power Plant Revision 0 Addendum No. 001 Department of Energy (DOE) per 10 CFR 50.54(bb), and (3) clean demolition of structures and restoration of the site to Greenfield conditions.
Accordingly, EnergySolutions established a Work Breakdown Structure (WBS) and cost accounting system to differentiate between three project accounts: "License Termination" (10 CFR 50.75(c)), "Spent Fuel" (10 CFR 10.54(bb)), or "Greenfield". The 2006 Cost Study costs and schedules for all activities were presented using these accounts. All costs were current as of September 2005.
The 2006 Cost Study analyzed six scenarios as defined by.Dominion. The current study is an update to the 2006 Cost Study Scenario 2. The cost summary for Scenario 2, summarized by account, is given in Table 2-1.

$334,313 $273,386 $19,170 $626,869 Scenario 2 was comprised of the following:
- DECON methodology.
- No license extension with shutdown on December 21, 2013.
- Terminate spent fuel pool operation seven years after permanent unit shutdown.
- Spent fuel will be stored in Multi-Purpose Canisters (MPCs) at an onsite Independent Spent Fuel Storage Installation (ISFSI) to be built in the future.
- A dry transfer facility will not be necessary.
- Yucca Mountain spent fuel repository opens in 2017.
This scenario incorporated the spent fuel schedule, developed by Dominion, modified to include the disposition of one Multi-Purpose Canister (MPC) containing Greater Than Class C (GTCC) waste. Spent fuel shipments to the DOE repository from the spent fuel pool begin in 2019 and are completed in 2047. The 10 CFR Part 50 license is terminated by 2021 with the 10 CFR Part 72 ISFSI license being terminated by 2048. The cost of a 10 CFR Part 72 ISFSI site-specific license and renewal was included. Figure 2-1 shows the summary project schedule, which was based on the spent fuel shipping constraints.

Decommissioning Cost Estimate Study of the Document No. 82A9584 Kewaunee Nuclear Power Plant Revision 0 Addendum No. 001 3.0 BASES FOR REVISED COST 3.1 Changes in Key Assumptions The key assumptions used in the 2006 Cost Study can be categorized as either financial or technical. Financial assumptions consist of the unit cost of labor, labor overhead (consisting of fringe benefits and overhead), material, equipment, energy, contractor services, insurance, regulatory fees and property taxes required to perform decommissioning and spent fuel management activities. Additionally, the financial assumptions include the escalation rates applied to the various cost components to calculate a net present value of the future decommissioning and spent fuel management liabilities.
Technical assumptions pertain to the means and methods applied to accomplish decommissioning while satisfying environmental, safety, health and all other regulatory requirements. Technical assumptions are also affected by external constraints such as the availability of both a spent fuel repository, or other means of spent fuel disposition, and Low Level Radioactive Waste (LLRW) disposal facilities. The timeframes for availability of these facilities have a direct impact on the overall project schedule for decommissioning and spent fuel management.
Two significant changes in key technical assumptions have occurred since completion of the 2006 Cost Study. These are:
- Effective July 2008, the Barnwell facility in South Carolina no longer accepts LLRW from generators outside the Atlantic Compact, which is comprised of the states of South Carolina, Connecticut and New Jersey. With the closure of the Barnwell disposal facility, Kewaunee will no longer have access to a disposal facility for Class B and C wastes.
" In July 2008, Edward Sproat, III, Director of the Office of Civilian Radioactive Waste Management, testified to the U.S. House of Representatives that 2020 will be the earliest possible opening date for the Department of Energy's Yucca Mountain repository (Ref.
No. 2).
The lack of a national capacity for Class B and C LLRW disposal will require generators to store these wastes on-site until a new facility is licensed and constructed to accept these wastes or until other commercial options for disposal become available. In keeping with guidance from DEK, EnergySolutions has incorporated the assumption that a Class B and C waste disposal facility will become available in 2025, and that the Phase 2 addition to the existing ISFSI may be licensed and used for interim storage of Class B and C waste.
As discussed in Section 2.1, the 2006 Cost Study assumed a Yucca Mountain opening date of 2017. Consistent with the recent Congressional testimony of Mr. Sproat regarding the Yucca Mountain opening date, EnergySolutions has incorporated a Yucca Mountain opening date of 2020 into the current update.

Decommissioning Cost Estimate Study of the Document No. 82A9584 Kewaunee Nuclear Power Plant Revision 0 Addendum No. 001 The current updated estimate now encompasses the following:
- DECON methodology.
- No license extension; shutdown on December 21, 2013.
" Termination of spent fuel pool operation seven years after permanent unit shutdown.
" Yucca Mountain opening date will be in 2020.
- The ISFSI Phase 2 construction cost. Phase 2 will be required to allow transfer of all spent fuel to the ISFSI. Spent fuel will be stored in Multi-Purpose Canisters (MPCs) at the existing onsite ISFSI as well at its addition.
- A dry transfer facility will notbe necessary.
- The ISFSI Phase 2 addition may be licensed and used for interim storage of Class B and C waste.
- A Class B and C waste disposal facility will become available in 2025.
" Updated costs are escalated to 2008 dollars and new cost elements added are based on 2008 cost data.
- Class B and C waste currently in inventory, along with an estimate of annual quantities generated during operations through shut-down, will be stored on-site until decommissioning.
3.2 Escalation to 2008 Dollars All 2006 Study costs were escalated from 2005 to 2008 dollars using the following annual aggregate escalation rates furnished by DEK:
2005 to 2006 3.863%
2006 to 2007 3.80%
2007 to 2008 3.814%
3.3 Revision of Spent Fuel Management Costs DEK provided EnergySolutions with an updated spent fuel shipping schedule incorporating the revised Yucca Mountain opening date of 2020. The spent fuel shipping schedule furnished by DEK is based in part on the DOE's "Acceptance Priority Ranking & Annual Capacity Report,"
dated July 2004 (Ref. No. 3). The updated spent fuel shipping schedule is provided in Appendix A.
The delay in the opening date of Yucca Mountain from 2017 to 2020 had three effects on the cost estimate. First, the number of dry storage modules to be purchased during decommissioning increased from 31 to 33. Second, the ISFSI demolition costs increased due to the increase in the number of dry storage modules. Third, the ISFSI operating costs increased because the duration of ISFSI operations was extended from 2047 to 2049.
Additionally, the spent fuel management costs were increased to account for (1) the ISFSI as-built and Phase 2 design information that was not available during the 2006 Cost Study, which contributed to the increased ISFSI demolition costs, and (2) the inclusion of the Phase 2 construction cost. The 2006 Cost Study assumed that the ISFSI would be sufficient to transfer all spent fuel into dry storage following shutdown.

Decommissioning Cost Estimate Study of the Document No. 82A9584 Kewaunee Nuclear Power Plant Revision 0 Addendum No. 001 3.4 Interim Storage of Class B and C LLRW The current lack of available Class B and C LLRW disposal capacity had the following effects on the cost estimate:
- 1. The ISFSI may have to be licensed for storage of these wastes.
- 2. Environmentally secure reinforced concrete storage modules must be purchased and may be installed on the ISFSI Phase 2 pad for receipt of Class B and C LLRW generated during decommissioning.
- 3. Class B and C LLRW generated during decommissioning, from chemical decontamination, filtration and segmentation of the reactor internals, will be placed in interim storage. Therefore, transportation and waste disposal costs for these activities will be deferred until 2025. At that time additional labor, material and equipment costs will be incurred to remove the wastes from the interim storage modules and place them in a shipping cask for transportation.
- 4. DEK will accumulate legacy Class B and C spent ion exchange resins and filters generated during operations that will require disposal during decommissioning.
- 5. The reinforced concrete storage modules will require radiological survey and disposal following completion of off-site disposal of the Class B and C wastes. Because the storage modules may be collocated at the ISFSI, the demolition of these modules is assumed to be deferred until the ISFSI demolition.
- 6. A new decommissioning period (Decon Pd 4d) was added to the project schedule and Work Breakdown Structure (WBS). This period consists of the removal of Class C and B waste in interim storage and transfer to a shipping cask for transportation and disposal.
The period also includes performance of a verification survey to terminate the interim waste storage facility license. The period extends from June 1, 2025 to June 26, 2026.
DEK provided EnergySolutions with construction details and pricing for Dufrane Nuclear Shielding, Inc. Secure Environmental Container (SEC) model 8-120-H storage modules. Each module is designed to store an 8-120 cask liner or High Integrity Container (HIC). The Class B and C decommissioning waste will require 35 SEC model 8-120-H storage modules. An additional 14 SEC model 8-120-H storage modules will be required for the spent ion exchange resin and filter waste generated during operations; however, the cost of purchasing these modules will be incurred prior to shutdown and therefore are not included in the decommissioning estimate.
The cost developed in the 2006 Cost Study for disposal of the Class B and C wastes generated during decommissioning was based on the Barnwell published base rate and surcharge structure, and assumed to be representative of waste disposal rates at a future Class B and C waste disposal facility. This assumption in the 2006 Cost Study is still considered to be valid, therefore, escalation of the Class B and C waste disposal costs using DEK's aggregate annual escalation rates is reasonable. As stated in Section 3.1 above, new cost elements incorporated into this update are based on 2008 costs. Therefore, the waste disposal costs in 2008 dollars for the added cost element consisting of the operational waste disposal was developed using the Barnwell Atlantic Compact Rate Structure effective July 2007, which is the most current pricing available.
The interim waste storage facility may be collocated with the spent fuel dry storage modules and Page 7 of 11
Decommissioning Cost Estimate Study of the Document No. 82A9584 Kewaunee Nuclear Power Plant Revision 0 Addendum No. 001 will require minimal maintenance and surveillance during the storage period; therefore, no additional undistributed costs were assumed to be required during Decon Pd 4d.
This study conservatively assumes that, following a radiological release survey, the reinforced concrete interim waste storage modules will be rubbleized and the resulting concrete and steel debris will be disposed of at a demolition debris landfill during the ISFSI demolition. However, it is likely that these storage modules could be transferred to another DEK power plant for reuse or sold to another nuclear utility.
3.5 Revised Scenario 2 Study Results Figure 3-1 is a summary project schedule. A detailed schedule is provided in Appendix B. The schedule is based on the spent fuel shipping constraints. The 10 CFR Part 50 license is terminated by 2021, with the 10 CFR Part 72 ISFSI license being terminated by 2050.
