SUMMARY
This report presents the results of a site-specific decommissioning cost estimate for FPL Energy Duane Arnold, LLC's (FPLE) Duane Arnold Energy Center (DAEC) 1. The study has been performed to furnish an estimate, for financial planning purposes, of the costs for (1) decommissioning DAEC to the extent required to terminate the plant's operating license pursuant to 10 CFR 50.75(c), (2) post-shutdown management of spent fuel until acceptance by the U.S. Department of Energy (DOE) pursuant to 10 CFR 50.54(bb), and (3) clean demolition of structures and restoration of the site to Greenfield conditions (Ref. No. 1). The study methodology follows the basic approach originally presented in the Atomic Industrial Forum/National Environmental Studies Project Report AIF/NESP-036, "Guidelines for Producing Commercial Nuclear Power Plant Decommissioning Cost Estimates," (Ref. No. 2). The report was prepared in accordance with Nuclear Regulatory Commission (NRC) Regulatory Guide 1.202, "Standard Format and Content of Decommissioning Cost Estimates for Nuclear Power Reactors," (Ref. No. 3). The estimate is based on compliance with current regulatory requirements and proven decommissioning technologies. NRC requirements set forth in Title 10 of the Code of Federal Regulations (CFR) differentiate between the post-shutdown costs associated with storage of. spent fuel on-site and those associated with the decommissioning of the facility. 10 CFR 50.75(c) requires funding by the licensee of the facility for the decommissioning program, but specifically excludes the cost of removal and disposal of spent fuel and the removal of clean structures. 10 CFR 50.75(c) also excludes the cost of site restoration activities that do not involve the removal of residual radioactivity necessary to terminate the NRC license, which restore the site to either "Brownfield" or "Greenfield" conditions depending on the desired end-state. 10 CFR 50.54 (bb) requires funding by the licensee "for the management of all irradiated fuel at the reactor upon expiration of the reactor operating license until title to the irradiated fuel and possession of the fuel is transferred to the Secretary of Energy for its ultimate disposal in a repository." Accordingly, the costs and schedules for all activities are segregated for regulatory purposes as follows: costs for "License Termination" (10 CFR 50.75(c)); costs for "Spent Fuel Management" (10 CFR 50.54(bb)); and costs for "Greenfield" (clean removal and site restoration) final site conditions. EnergySolutions has established a Work Breakdown Structure (WBS) and cost accounting system to differentiate between these three project accounts. The study analyzes .the following four decommissioning scenarios for DAEC, as defined by FPLE: Scenario 1 Base Case
" DECON methodology.
" No license extension, with shutdown on February 21, 2014.
" Terminate spent fuel pool operation five years after permanent unit shutdown.
" Spent fuel will be stored at the existing Independent Spent Fuel Storage Installation (ISFSI).
FPLE owns 70% of and operates DAEC. The other owners of DAEC are Central Iowa Power Cooperative (20%) and Corn Belt Power Cooperative (10%). All numbers presented in this report are on a 100% basis. Page 4 of 58

" Class B and C waste will be temporarily stored in an on-site interim waste storage facility to be built during decommissioning. Class B and C waste are assumed to be stored on-site until 2025, which is the assumed date a licensed facility would be available to receive these wastes.
" The DOE Yucca Mountain repository, or other approved method of spent fuel disposition, will be available starting in 2025.
Scenario 2 Base case, except using SAFSTOR methodology.
- Class B and C waste generated during operations and SAFSTOR preparations will be stored in the existing Low Level Radwaste Storage Building until 2025, which is the assumed date a licensed facility would be available to receive these wastes.
Scenario 3 Base case, except 20-year license extension, and no requirement for on-site interim storage of Class B and C waste. Scenario 4 Scenario 2, except with 20-year license extension, and no requirement for on-site interim storage of Class B and C waste. Each scenario incorporates the spent fuel schedules developed by FPLE. All scenarios are based on performance of decommissioning by a Decommissioning General Contractor (DGC) under the management and supervision of DAEC staff. DAEC staff will be supplemented with a professional engineering consulting firm for planning and preparation, engineering design, and final status survey. The cost estimate results for all four scenarios are provided in 2008 dollars in Tables 1-1; 1-2, and 1-3.

These inventories and EnergySolutions' proprietary Unit Cost Factors (UCFs) were used to generate required manhours, activity schedule hours and costs, and waste volume, weight, and classification. Based on the activity schedule hours and a decommissioning activities analysis, a Critical Path Method (CPM) analysis was performed to determine the decommissioning schedules. These schedules reflect the effects of sequenced activity-dependent or distributed decommissioning elements such as planning and preparations, major component removal, building decontamination, and spent fuel shipping. The schedules are divided into project phases (periods) and presented, as noted previously, by cost account "License Termination," "Spent Fuel Management," or "Greenfield." The summary schedule for Scenario 1 is shown in Figure 1-1. The summary schedules for all the scenarios may be found in sections 6.1 through 6.4 of this report. Page 6 of 58

2.0 INTRODUCTION
2.1 Study Objective This report presents the results of a site-specific decommissioning cost estimate for FPL Energy Duane Arnold, LLC's (FPLE) Duane Arnold Energy Center (DAEC). The study has been performed to furnish an estimate, for financial planning purposes, of the costs for (1) decommissioning DAEC to the extent required to terminate the plant's operating license pursuant to 10 CFR 50.75(c), (2) post-shutdown management of spent fuel until acceptance by the U.S. Department of Energy (DOE) pursuant to 10 CFR 50.54(bb), and (3) clean demolition of structures and restoration of the site to Greenfield conditions (Ref.

Decommissioning Cost Estimate Study Document No. 82A9634 for the Duane Arnold Energy Center Revision 0 2.2 Regulatory Framework Provisions of current laws and regulations affecting decommissioning, waste management and spent fuel management are as follows:
- 1. Current NRC policy requires either: (a) removal of all spent fuel from a facility licensed under 10 CFR 50, or (b) on-site storage of spent fuel at an ISFSI under the general license set forth in 10 CFR 72, or (c) on-site storage of spent fuel under a site-specific ISFSI Part 72 license, before the license can be terminated
- 2. 10 CFR 50.75(c) requires funding by the licensee of the facility for the decommissioning program, but specifically excludes the. cost of removal and disposal of spent fuel and the removal of clean structures.
- 3. 10 CFR 50.54 (bb) requires the licensee, within two years following permanent cessation of operation of the reactor or five years before expiration of the operating license, whichever occurs first, to submit written notification to the NRC for its review and preliminary approval of the program by which the licensee intends to manage and provide funding "for the management of all irradiated fuel at the reactor upon expiration of the reactor operating license until title to the irradiated fuel and possession of the fuel is transferred to the Secretary of Energy for its ultimate disposal in a repository." However, the NRC does not currently consider post-shutdown spent fuel management costs to be decommissioning costs.
- 4. 10 CFR Part 961 (Ref. No. 4), Appendix E, requires spent fuel to be cooled in the spent fuel pool for at least five years before it can be accepted by DOE.
- 5. A bill to enact the "Atlantic Interstate Low-Level Radioactive Waste Compact Implementation Act" was signed by the Governor of South Carolina on June 6, 2000. The Atlantic Compact consists of South Carolina, Connecticut and New Jersey. Under the Act, effective June 2008, the Atlantic compact now prohibits out-of-region low level waste (LLW) generators, including FPLE, from disposing of LLW at the Barnwell disposal facility. Barnwell is one of only two facilities in the United States currently licensed to dispose of Class B and C LLW.
Decommissioning Alternatives The three basic methods for decommissioning are DECON, SAFSTOR, and ENTOMB, which are summarized as follows:
- 1. DECON: The equipment, structures, and portions of the facility and site that contain radioactive contaminants are promptly removed or decontaminated to a level that permits termination of the license after cessation of operations.
- 2. SAFSTOR: The facility is placed in a safe, stable condition and maintained in that state (safe storage). The facility is decontaminated and dismantled at the end of the storage period to levels that permit license termination. NRC regulations require decommissioning to be completed within 60 years of cessation of Page 9 of 58
Decommissioning Cost Estimate Study Document No. 82A9634 for the Duane Arnold Energy Center Revision 0 operation. Durations less than the regulatory-allowed maximum may be referred to as Modified SAFSTOR.
- 3. ENTOMB: Radioactive structures, systems, and components are encased in a structurally long-lived substance, such as concrete. The entombed structure is appropriately maintained and monitored until radioactivity decays to a level that permits termination of the license. Since entombment will exceed the requirement for decommissioning to be completed within 60 years of cessation of operation, NRC handles entombment requests on a case-by-case basis.
The selection of a preferred decommissioning alternative is influenced by a number of factors pertinent at the time of final plant shutdown. These factors include the cost of each decommissioning alternative, minimization of occupational radiation exposure, availability of a low-level waste disposal facility, availability of a high-level waste (spent fuel) repository, regulatory requirements, and public concerns. Post-Shutdown Spent Fuel Management Alternatives The earliest date for start-up of the DOE's Yucca Mountain repository is currently 20202. However, there is considerable uncertainty associated with this scheduled opening. Per guidance from FPLE, this study assumes that the DOE Yucca Mountain repository, or other approved method of spent fuel disposition, will be available starting in 2025. Therefore, long-term post-shutdown spent fuel storage must be addressed as an integral element of decommissioning planning. The basic options for long-term post-shutdown spent fuel management are (1) wet storage consisting of continued maintenance and operation of the spent fuel pool, (2) dry storage consisting of transfer of spent fuel from the fuel pool to on-site dry storage modules following the minimum cooling period, and (3) off-site storage at a licensed private or commercial storage facility. The third option is not commercially viable as of the date of this study. The selection of a spent fuel management alternative has a significant impact on decommissioning. Maintaining the spent fuel pool for an extended duration following cessation of operations prevents termination of the Part 50 license and typically has a higher annual maintenance and operating cost than the dry storage alternative. Transfer of spent fuel to an ISFSI requires (1) capital expenditures for purchase and construction of the ISFSI, if needed, and (2) dismantlement and disposal of the ISFSI following completion of spent fuel transfer to DOE. 2 Summary, Edward F.

Decommissioning Cost Estimate Study Document No. 82A9634 for the Duane Arnold Energy Center Revision 0 3.0 STUDY METHODOLOGY 3.1 General Description EnergySolutions maintains a proprietary decommissioning cost model based upon the fundamental technical approach established in AIF/NESP-036, "Guidelines for Producing Commercial Nuclear Power Plant Decommissioning Cost Estimates," dated May 1986 (Ref. No. 2). The cost model has been continuously updated in accordance with regulatory requirements and industry experience. The cost model includes elements for estimating distributed and undistributed costs. Distributed costs are activity specific and include planning and preparation costs as well as the decontamination, packaging, disposal, and removal of major components and systems. For example, the segmentation, packaging, and disposal of the reactor internals is a distributed cost. Undistributed costs, sometimes referred to as collateral costs, are typically time dependent costs such as utility and decommissioning general contractor staff, property taxes, insurance, regulatory fees and permits, energy costs, and security staff. The methodology for preparing cost estimates for a selected decommissioning alternative requires development of a site-specific detailed work activity sequence based upon the plant inventory. The activity sequence is used to define the labor, material, equipment, energy resources, and duration required for each activity. In the case of major components, individual work sequence activity analyses are performed based ýon the physical and radiological characteristics of the component and the packaging, transportation, and disposal options available. In the case of structures and small components and equipment such as piping, pumps, and tanks, the work durations and costs are calculated based on Unit Cost Factors (UCFs). UCFs are economic parameters developed to express costs per unit of work output, piece of equipment, or time. They are developed using decommissioning experience, information on the latest technology applicable to decommissioning, and engineering judgment. The total cost of a specific decommissioning activity can be determined by multiplying the total number of units associated with that activity by the UCF, expressed as $/unit, for that activity. For example, the estimated demolition cost of a non-contaminated concrete structure can be obtained by multiplying the volume of concrete in the structure by the UCF for non-contaminated reinforced concrete demolition, expressed in $/unit volume. Each UCF has associated with it a man-hours/unit and schedule-hours/unit. From these values, total man-hours and total schedule-hours can be determined for a particular activity. 3.2 Schedule Analysis Once the work activity durations are calculated for all distributed activities, a critical path schedule analysis is performed using MS Project. The schedule accounts for constraints such as spent fuel cooling periods and regulatory reviews. The schedule is typically delineated into phases or time periods (hereinafter referred to as period or periods) that differentiate manpower requirements and undistributed costs. In order to differentiate between License Termination, Spent Fuel and Greenfield elements of the entire decommissioning scope of work, EnergySolutions has established a Work Breakdown Structure (WBS) and cost accounting system to treat each element as a subproject. Accordingly, the overall project schedule is divided into interrelated periods with major milestones defining Page 11 of 58
Decommissioning Cost Estimate Study Document No. 82A9634 for the Duane Arnold Energy Center Revision 0 the beginning and ending of each period. The major milestones also serve as the basis for integrating the periods of the three subprojects. The License Termination and Greenfield project periods are scheduled sequentially while the Spent Fuel periods occur in parallel. 3.3 Decommissioning Staff EnergySolutions' philosophy towards decommissioning is to assume the project will be performed in an efficiently planned and executed manner using project personnel experienced in decommissioning. EnergySolutions assumes that the decommissioning will be performed by a highly experienced and qualified Decommissioning General Contractor (DGC), with oversight and management of the decommissioning operations performed by DAEC staff. It was also assumed that DAEC staff would be supplemented by professional consulting engineering, particularly in the planning and preparation phase. EnergySolutions analyzed the DAEC operational staff and developed a site-specific staffing plan. The DAEC existing salary structure was then used as the basis for calculating DAEC staff labor costs. EnergySolutions used industry data to develop DGC salary costs. Staffing levels, for both staffing plans and for each project period, are based on the AIF guidelines and industry experience. The sizes of the staffs are varied in each period in accordance with the requirements of the work activities. DAEC staffing has been organized into the following departments or functional groups:
" Administration
" Engineering
- Health Physics
- Management
- Plant Maintenance
- Plant Operations
- Quality Assurance
- Security Administration
- Security Guard Force
- Waste Operations
" Fuel Pool Maintenance and Operation Staff
" Additional Staff for Spent Fuel Shipping
" DGC Staff Page 12 of 58
Decommissioning Cost Estimate Study Document No. 82A9634 for the Duane Arnold Energy Center Revision 0 3.4 Waste Disposal Waste management costs comprise .a significant portion of the decommissioning cost estimate. Additionally, limited future access to disposal sites licensed for receipt of Class B and C wastes introduces a significant level of uncertainty with respect to the appropriateness of using existing rate structures to estimate disposal costs of these wastes. EnergySolutions' approach to estimating waste disposal costs is discussed in the following paragraphs. Waste Classification Regulations governing disposal of radioactive waste are stringent in order to ensure control of the waste and preclude adverse impact on public health and safety. At present, low-level radioactive waste (LLRW) disposal is controlled by NRC Regulation 10 CFR 61 (Ref. No. 4), which went into effect in December, 1983. This regulation stipulates the criteria for the establishment and operation of shallow-land LLRW burial facilities. Embodied within this new regulation are criteria and classifications for packaging LLRW such that it is acceptable for burial at licensed LLRW disposal sites. For each waste classification, 10 CFR 61 stipulates specific criteria for physical and chemical properties that the LLRW must meet in order to be accepted at a licensed disposal site. The LLRW disposal criteria of 10 CFR 61 require that LLRW generators determine the proportional amount of a number of specific radioactive isotopes present in each container of disposable LLRW. This requirement for isotopic analysis of each container of disposable LLRW is met by employing a combination of analytical techniques such as computerized analyses based upon scaling factors, sample laboratory analyses, and direct assay methods. Having performed an isotopic analysis of each container of disposable LLRW, the waste must then be classified according to one of the classifications (Class A, B, C or Greater Than Class C (GTCC)) as defined in 10 CFR 61. EnergySolutions' classification of LLRW resulting from decommissioning activities is based on AIF/NESP-036 (Ref. No. 2), NUREG/CR-0130 (Ref. No. 5), NUREG/CR-0672 (Ref. No. 6), and recent industry experience. The estimated curie content of the reactor vessel and internals at shutdown is derived from NUREG/CR-0130 for Pressurized Water Reactors (PWRs) and NUREG/CR-0672 for Boiling Water Reactors (BWRs) and adjusted for the different mass of components as well as the MWt rating and period of decay. Packaging Selection of the type and quantity of containers required for Class B and C wastes is based on the most restrictive of either curie content, dose-rate, container weight limit, or container volume limit. GTCC wastes from segmentation of the reactor vessel internals is packaged in fuel bundle canisters. The selection of container type for Class A waste is based on the transportation mode (rail, truck, barge, etc.) and waste form. The quantity. of Class A waste containers is determined by the most restrictive of either container weight limit or container volume limit. Large components, such as steam generators, pressurizers, and reactor recirculation pumps, are shipped as their own container with shielding as required. Container costs are obtained from manufacturers. Shielded transport cask and liner costs are obtained from the cask owners and operators. Page 13 of 58
Decommissioning Cost Estimate Study Document No. 82A9634 for the Duane Arnold Energy Center Revision 0 Transportation Transportation routes to processing and disposal facilities are determined based on available transportation modes (truck, rail, barge or combinations). Routes and distances are determined using the Transportation Routing Analysis Geographic Information System (TRAGIS) software developed by the Oak Ridge National Laboratory National Transportation Research Center (Ref. No. 7). Transportation costs for the selected routes and modes are obtained from vendor quotes or published tariffs whenever possible. Class A Disposal Options and Rates In accordance with the existing Life-of-Plant Disposal Agreement (Ref. No. 8), all Class A waste that meets the Clive facility waste acceptance criteria is to be disposed of at Clive. All reported waste disposal costs include packaging, transportation, and any applicable surcharges. Class B and C Disposal Options and Rates Currently, within the United States, there are only two commercial disposal facilities licensed to accept Class B and C LLRW: the Barnwell facility, operated by EnergySolutions in Barnwell, South Carolina, and the U.S. Ecology facility in Richland, Washington. However, Barnwell only accepts waste from states within the Atlantic Compact, and U.S. Ecology only accepts waste from states within the Northwest and Rocky Mountain Compacts. The Low-Level Waste Policy Act (LLWPA), passed by Congress in 1980, placed the responsibility of LLRW disposal in the hands of individual states. The LLWPA provided a six-year time frame within which each state was required to develop its own means for radioactive disposal. The LLWPA also provided for a group of states to form a compact, which could then establish the means for LLRW disposal on a regional basis. The intent of the LLWPA was to have new LLRW disposal sites in operation before January 1, 1986, therefore permitting closures of the three existing burial sites located in South Carolina, Washington, and Nevada. Since no new disposal sites were in operation by 1986, it is evident that the LLWPA failed to motivate the individual states to comply with its purpose. On January 15, 1986, Congress amended the LLWPA with passage of Public Law 99-240. In June of 1992, the U.S. Supreme Court ruled that the provisions of the amendment requiring any state to take title to the waste of its generators, if that state had not met its program milestones dates, were unconstitutional. The Supreme Court's invalidation of the "take title" provision has contributed to a lack of significant progress by many States in coming to grips with the problem. The question then becomes: what disposal rate is to be used in the decommissioning cost estimate for Class B and C LLRW and where is it to go? Since the cost estimate is based on current or present day dollars, the disposal cost for Class B and C LLRW should be equivalent to the cost that would be incurred if a new disposal facility were to be licensed and begin operations today. EnergySolutions has reviewed several studies developed in an attempt to quantify the disposal costs associated with a new disposal facility constructed in today's environment. Based Page 14 of 58
Decommissioning Cost Estimate Study Document No. 82A9634 for the Duane Arnold Energy Center Revision 0 on this review, it is EnergySolutions' belief that Class B and C LLRW disposal rates based on the published base rate and surcharge structure for the Barnwell facility is the most reasonable approach. This approach is also based on the fact that NRC requires utilities to update their decommissioning cost estimates every five years so that changes in disposal options and costs can be taken into account. Greater Than Class C (GTCC) Wastes identified as 10 CFR 61 Class A, B, and C may be disposed at a near-surface disposal facility. Certain components are highly activated and may exceed the radionuclide concentration limitations for 10 CFR 61 Class C waste. In accordance with 10 CFR 61, these components cannot be disposed of in a near-surface LLRW disposal facility and must be transferred to a geologic repository or a similar site approved by the NRC. Highly activated sections of the reactor vessel internals will result in GTCC waste. Presently, a facility does not exist for the disposal of wastes exceeding 10 CFR 61 Class C limitations. EnergySolutions assumes that the DOE will accept this waste at the Yucca Mountain repository facility along with spent fuel. However, unlike spent fuel, the disposal cost is not addressed by DOE's 1-mill/kWhr surcharge. Therefore, EnergySolutions estimates a GTCC waste disposal cost based upon the maximum curie surcharges currently in effect at Barnwell. EnergySolutions assumes that the GTCC waste will be packaged in fuel bundle canisters, either stored in the fuel pool or dry storage containers, and be shipped to Yucca Mountain by DOE along with the spent fuel. Additionally, EnergySolutions assumes shipping costs for GTCC waste to be equivalent to the commercial cost of shipping a Type B licensed, shielded cask such as the CNS 8-120B cask which is owned and operated by EnergySolutions. Non-Radioactive Non-Hazardous Waste Disposal EnergySolutions assumes that recyclable, non-radioactive scrap metal resulting from the decommissioning program will be removed from the site by a scrap metal dealer at no cost to the project. Concrete debris is assumed to be processed by size reduction, with removal of structural reinforcing steel, and used on site as engineered fill for voids. All other demolition debris is removed from the site and disposed of at a local construction debris landfill. Hazardous and Industrial Waste Disposal Uncontaminated lead shielding remaining after shutdown was assumed to be removed from its installed locations and shipped offsite by entities having a need for the material. The entities receive the lead at no charge in return for providing the removal and shipping services. In accordance with information furnished by FPLE seven percent of insulated systems in. radiologically controlled areas are assumed to contain asbestos, therefore; the decommissioning cost estimate includes a line item for asbestos abatement. The decommissioning estimate also includes an estimate for hazardous and industrial waste disposal based on information provided in the "DAEC 2007 Hazardous Waste Report." The cost of hazardous and industrial waste disposal includes FPLE's estimated cost for closure of Resource Conservation and Recovery Act (RCRA) storage area. Page 15 of 58
Decommissioning Cost Estimate Study Document No. 82A9634 for the Duane Arnold Energy Center Revision 0 3.5 Final Status Survey The cost of performing a final status survey (FSS) is based on NUREG-1575, "Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM)" (Ref. No. 9). Estimates of MARSSIM Class I, II and III survey designations are based on radiological characterization data furnished by DAEC and assumptions regarding contamination resulting from small and large component removal activities. The FSS activity cost calculation includes the in-place remote survey of underground metal and concrete pipe, soil, and groundwater sampling and analysis. Estimated costs for NRC and Oak Ridge Institute for Science and Education (ORISE) verification are also included, and the NRC review period is incorporated into the project schedule. 3.6 Contingency Contingencies are applied to cost estimates primarily to allow for unknown or unplanned occurrences during the actual program, e.g. increased radioactive waste materials volumes over that expected; equipment breakdowns; weather delays; labor strikes, etc. This is consistent with the definition provided in the DOE Cost Estimating Guide, DOE G 430.1-1, 3-28-97 (DOE G) (Ref. No. 10): Contingency "Covers costs that may result from incomplete design, unforeseen and unpredictable conditions, or uncertainties within the defined project scope. The amount of contingency will depend on the status of design, procurement, and construction; and ,the complexity and uncertainties of the component parts of the project. Contingency is not to be used to avoid making an accurate assessment of expected costs." EnergySolutions determines site-specific contingency factors to be applied to each estimate based on industry practices. The DOE has established a recommended range of contingencies as a function of completeness of program design, DOE G. The ranges are: Contingency Range Type of Estimate as a % of Total Estimate Planning Phase Estimate 20-30 Budget Estimate 15-25 Title I (Preliminary Design Estimate) 10-20 Title II (Definitive Design Estimate) 5-15 EnergySolutions' approach to assigning appropriate contingency rates is based on adaptations of published values for the specific decommissioning activities. One source for such published information is AIF/NESP-0036 "Guidelines for Producing Nuclear Plant Decommissioning Cost Estimates" (AIF) (Ref. No. 2). This document identifies contingencies for activities specific to a nuclear power plant decommissioning, such as reactor internals removal. The contingencies presented in this document are based on the assumption that the estimated costs are optimistic; therefore, the published contingencies are greater than they would be if the estimated costs were most probable. With the exception of the system decontamination, reactor vessel and reactor internals removal, and disposal, the contingencies presented in AIF are consistent with the values presented in DOE G 430.1-1 for a Budget/Title I estimate. The system decontamination, reactor vessel and reactor internals removal, and disposal contingencies are significantly higher than the ranges identified by the DOE, even for a planning phase document. This is due to the unique nature of these activities and the relatively small amount of historical data available at the time the AIF document was written. Page 16 of 58
Decommissioning Cost Estimate Study Document No. 82A9634 for the Duane Arnold Energy Center Revision 0 EnergySolutions has developed contingencies specific to decommissioning estimates utilizing the information presented in AIF and consistent with DOE G. The decommissioning costs generated by EnergySolutions are considered most probable and, as such, the contingencies presented in AIF were reduced for each category of costs. There have also been a number of large-scale decommissioning projects since AIF was published, providing some historical information that can be used in preparing current estimates. This allows for additional reduction in contingency costs. The following table provides a summary of contingency values used in EnergySolutions' estimates where the plant structures, systems, and major component material inventories are well defined, as with this study. Package Material & Ship & Category Labor E quipment Bury Other Engineering, Utility & DGC 13% Contaminated components/Concrete 23% 23% 23% Clean components 13% 23% 13% Reactor Vessel and Reactor Internals 50% 23% 25% Other 15% A reactor decommissioning program will be conducted under an NRC-approved Quality Assurance Program which meets the requirements of 10 CFR 50, Appendix B, of the Code of Federal Regulations. However, the development of the quality assurance program, the performance of work under that program, and the effort required to ensure compliance with the program, is already included in the detailed cost estimate. Therefore, EnergySolutions does not include quality assurance as an element of the contingency allowance. The same is true for contamination. Where radioactive contamination or activated materials are dealt with, the EnergySolutions unit cost factors and associated calculations fully reflect the cost impact of that material, and a separate contingency is not required specifically due to working with contamination. 3.7 Cost Reporting Total project costs are aggregated from the distributed activity and undistributed costs into the following categories - Labor, Materials and Equipment, Waste Disposal, and Other costs. Other costs include property taxes, insurance, license fees, permits, and energy. Waste disposal costs are the summation of packaging, transportation, base disposal rate, and any applicable surcharges. Health physics (HP) supplies and small tool costs are calculated as a component of each distributed activity cost and included in the category of Material and Equipment, with the exception that HP supplies for DAEC HP staff are calculated and reported as an undistributed line item. A line item specific contingency is then calculated for each activity cost element. Page 17 of 58
Decommissioning Cost Estimate Study Document No. 82A9634 for the Duane Arnold Energy Center Revision 0 4.0 SITE SPECIFIC TECHNICAL APPROACH 4.1 Facility Description DAEC is a nuclear powered electrical generating facility consisting of one BWR located on a site near Palo in Linn County, Iowa. The plant site comprises approximately 500 acres adjacent to the Cedar River approximately 2.5 miles northeast of the Village of Palo, Iowa. The nuclear system includes a single-cycle, forced-circulation, General Electric (GE) BWR producing steam for direct use in the steam turbine. The nuclear steam supply system (NSSS) and the turbine-generator were furnished by GE. The balance of plant was designed and constructed by Bechtel Power Corporation (Bechtel) as architect engineer and constructor. The unit was originally designed, analyzed, and licensed for a steady-state core power of 1658 MWt, although the plant Technical Specifications restricted operation to a rated power of 1593 MWt. In 1985, the Technical Specifications were amended to allow the DAEC to operate at a steady-state power level of 1658 MWt (License Amendment #115). Then, in 2001, the rated power level was increased again to 1912 MWt (License Amendment #243). The current shutdown date is February 21, 2014. Spent fuel assemblies are stored in the spent fuel storage racks in the fuel pool or may, after appropriate decay, be transferred to an ISFSI for interim onsite storage. The DAEC has been authorized by NRC to increase the storage capacity of the DAEC spent fuel pool to 2829 assemblies. In addition, a Cask Pit is also licensed to contain a rack with storage capacity of 323 assemblies. The Cask Pit rack is used as a means to retain full-core offload capability after such capacity is exhausted in the spent fuel pool. The DAEC may or may not exercise this option in the future. The re-rack project of 1994 increased the spent fuel pool capacity to 2411 assemblies. Subsequent re-rack projects will be undertaken only if the DAEC chooses to do so after having considered all other practicable options. There is an ISFSI on site that houses 10 CFR 72 licensed spent fuel storage systems that can provide interim on-site storage of spent fuel, high-level radioactive waste, and reactor-related GTCC waste. Appendix A provides a list of the DAEC systems and structures included in the material inventory for this study. 4.2 Decommissioning Periods for Scenario 1 The project periods defined for Scenario 1 (Base Case, DECON) consist of five License Termination periods, four Spent Fuel Management periods, and two Greenfield periods. The License Termination periods and Spent Fuel Management periods occur simultaneously. The Greenfield periods follow the License Termination periods sequentially. The project periods defined for this site-specific study and the major activities performed during each period are as follows: Page 18 of 58

" Finish Grading and Seeding 4.6 Decommissioning Staff For this study, EnergySolutions developed staffing based on the assumption that decommissioning will be performed by an experienced and qualified DGC, with oversight and management of the decommissioning operations performed by DAEC staff. It is also assumed that DAEC staff is supplemented by professional consulting engineering, particularly in the planning and preparation phase. The sizes of the staffs are varied in each period in accordance with the requirements of the work activities. Details on the staff levels by functional group during each period are provided in Section 6.0 for each scenario.
4.7 Spent Fuel Management Staff The largest spent fuel staff occurs while the fuel pool is operational during the minimum cooling period and the fuel assemblies are being transferred to either the DOE repository or dry storage. Once all spent fuel has been removed from the spent fuel pool, the staff is reduced. During spent fuel pool operations and the dry storage period, the full-time spent fuel management staff is supplemented with part-time staff to support fuel movements. Details on the staff levels by functional group during each period are provided in Section 6.0 for each scenario. Page 26 of 58
Decommissioning Cost Estimate Study Document No. 82A9634 for the Duane Arnold Energy Center Revision 0 4.8 Spent Fuel Shipments The spent fuel shipment schedules for each scenario are based on information from FPLE regarding existing fuel inventory, planned transfers to dry storage, planned off-loads during outages, the DOE shipment schedule, and the full core off-load. The spent fuel shipping schedules are also based, in part, on the DOE's "Acceptance Priority Ranking & Annual Capacity Report," dated July 2004 (Ref. No. 11). Spent fuel shipping schedules for each scenario are provided in Appendix B. Page 27 of 58
Decommissioning Cost Estimate Study Document No. 82A9634 for the Duane Arnold Energy Center Revision 0 5.0 BASES OF ESTIMATE AND KEY ASSUMPTIONS The bases of and key assumptions for this site-specific decommissioning estimate are presented below:
- 1. All cost data used in this study is current as of 2008 or has been escalated to 2008 dollars. Totals and subtotals have been rounded to significant figures.
- 2. The decommissioning will be performed under the current regulations. These regulations require a Post-Shutdown Decommissioning Activities Report (PSDAR) to be submitted prior to, or within, two years after permanent shutdown. In addition, a certificate of permanent cessation of operations must be submitted to the NRC within 30 days of permanent cessation of operations. Certification of the final core off-load must also be submitted to the NRC upon completion of this activity. Ninety days after the NRC receives the PSDAR and after submittal of both certifications, major decommissioning activities that meet the criteria of 10 CFR Part 50.59 may be performed, provided the NRC does not notify DAEC of any deficiencies.
- 3. The decommissioning will be performed using currently available technologies.
- 4. EnergySolutions developed prompt dismantlement (DECON) and delayed dismantlement (SAFSTOR) project schedules based on a shutdown date of February 21, 2014 for Scenarios l and 2. For Scenarios 3 and 4, with a 20 year license extension, a shutdown date of February 21, 2034 was used.
- 5. A DOE repository is assumed to exist by an opening date of January 1, 2025.
- 6. This estimate's material inventory is based on EnergySolutions takeoffs from the site drawings and information furnished by FPLE.
- 7. All transformers on site following shutdown are assumed to be PCB-free.
- 8. No PCBs will be on site at shutdown.
- 9. Clean scrap metal is assumed to be recycled at no cost to the project. Concrete debris is assumed to be processed by size reduction, with removal of structural reinforcing steel, and used on site as engineered fill for voids. All other demolition debris is removed from the site and disposed of at a local off-site construction landfill.
- 10. All scenarios are based on final site restoration to Greenfield conditions, in which all existing and proposed structures, with the exception of the switchyard, will be removed.
Clean demolition costs are based on structures removal to three feet below grade. Clean topsoil will be imported and placed on the top three feet. The entire disturbed area of the site is to be graded, to restore the natural grade to the extent possible, and seeded. Page 28 of 58
Decommissioning Cost Estimate Study Document No. 82A9634 for the Duane Arnold Energy Center Revision 0
- 11. Uncontaminated lead shielding remaining after shutdown was assumed to be removed from its installed locations and shipped offsite by entities having a need for the material. The entities receive the lead at no charge in return for providing the removal and shipping services.
- 12. No known areas of radiologically contaminated soil have been identified. Additionally, documented tritium levels in groundwater are below drinking water standards.
Therefore, no soil or groundwater remediation costs will be assumed. However, costs for environmental monitoring performed during decommissioning will include groundwater monitoring.
- 13. A budget for hazardous material is included in the estimate, based on the 2007 EPA report provided by FPLE. All other chemicals and hazardous materials present at shutdown are assumed to be removed and disposed of by the plant staff prior to decommissioning, as a normal part of plant operations.
- 14. DAEC provided information on the current amount of asbestos insulation on systems piping. It is assumed that asbestos not replaced during an outage and still remaining at shutdown will be limited to areas with higher dose rates. Therefore, this study considers that 7% of the insulation on contaminated and insulated piping will be asbestos, and disposed of as Class A waste.
- 15. All Class A waste is assumed to be disposed of at EnergySolutions' facility in Clive, Utah, in accordance with the existing Life-of-Plant Disposal Agreement between EnergySolutions and FPL Energy Duane Arnold, LLC dated January 2007. The following 2008 disposal rates will be applied:
Demolition Debris and Soil - $52.00/Cubic Foot plus 5% Utah taxes Oversized Debris - $100.00/Cubic Foot plus 5% Utah taxes Containerized Waste Facility - $193.00/Cubic Foot plus 12% Utah taxes Large Components - $260.00/Cubic Foot plus 5% Utah taxes Cask Shipments - $39,513/Cask
- 16. Class B, C and Greater-than-Class-C (GTCC) wastes disposal costs are based on the July 2008 published rates for the Barnwell facility, including applicable curie and dose rate surcharges.
- 17. It is assumed that all Class A low-level waste currently being accumulated on-site will be removed to a low-level waste processing and/or disposal facility prior to the end of the operating life of the plant. The disposition of such materials is assumed not to be a decommissioning cost.
- 18. GTCC waste generated from the segmentation of the reactor internals will be packaged in fuel bundle sized containers and stored on-site in NUHOMS canisters placed in horizontal storage modules (HSMs) at the ISFSI for final disposition at a DOE repository.
Page 29 of 58
Decommissioning Cost Estimate Study Document No. 82A9634 for the Duane Arnold Energy Center Revision 0
- 19. Vessel and internals curie estimates were derived from the values for the Reference BWR vessel and internals in NUREG/CR-0672 (Ref. No. 6). These values were adjusted for MWt rating, weight and decay period.
- 20. Scenarios 1 and 2 (existing license termination) assume that Class B and C waste generated during operations will be stored on site until 2025, at which time a facility licensed to dispose of Class B and C wastes will become available.
2-1. Scenarios 3 and 4 (license extension) assume that all Class B and C waste generated during operations, and wastes stored on site on an interim basis, will be disposed of prior to the end of the operating life of the plant. Therefore, the disposition of such materials is not assumed to be a decommissioning cost.
- 22. The spent fuel shipping schedules developed by EnergySolutions are based on data provided by FPLE. The shipping schedules assume a five year spent fuel cooling period prior to transfer to dry storage canisters or the DOE. The number of spent fuel assemblies shipped from the ISFSI to the DOE have been adjusted to full cask shipments, with residual allocations carried forward to subsequent years.
- 23. Spent fuel management costs include the purchase of NUHOMS-61BT dry storage canisters and HSMs required for spent fuel following shutdown, based on the requirements of each scenario. Costs of $695,662 per canister and $400,155 per HSM were assumed for this study.
- 24. The HSMs are assumed to have no activated concrete. The ISFSI demolition cost also assumes no activation or surface contamination of the HSMs.
- 25. Emergency Preparedness (FEMA) fees and Environmental Affairs costs are based on data furnished by FPLE and were adjusted by EnergySolutions to meet the requirements of each period based on the status of on-site spent fuel. The annual operating costs for these items are as follows:
FEMA fees - $1,016,289/year Environmental Affairs - $7,367/year
- 26. Annual property taxes in the amount of $10,000/year through the end of the project are included.
- 27. EnergySolutions has included the annual NRC 10 CFR 171.15 fees, for reactors in decommissioning, of $135,000/yr per unit until decommissioning is completed.
- 28. EnergySolutions has included the annual NRC 10 CFR 171.15 fees of $135,000/yr for on-site dry storage during all post-shutdown years with dry storage. EnergySolutions has assumed that the 10 CFR Part 50 license will be continued until all fuel is offsite.
- 29. Annual insurance premiums are based on 2008 data supplied by FPLE, and adjusted by EnergySolutions to meet the requirements of each period. The applicable 2008 premiums provided are as follows:
Page 30 of 58
Decommissioning Cost Estimate Study Document No. 82A9634 for the Duane Arnold Energy Center Revision 0 Nuclear Property - $508,159 Nuclear Liability - $687,577 Excess Liability - $973,058 Non-Nuclear Liability - $250,000
- 30. Supplies and services costs were calculated based on information provided by FPLE and adjusted by EnergySolutions to match the requirements of each period, based on staffing levels.
- 31. No severance costs have been included in this estimate in accordance with existing FPLE policy.
- 32. The decommissioning will be performed by a DGC under the management and supervision of DAEC staff. DAEC staff will be supplemented with a professional engineering consulting firm for planning and preparation, engineering design, and final status survey.
- 33. DAEC staff positions and average direct burdened salary data was supplied by FPLE.
These rates were current as of August 2008. An overhead rate of 43% was applied to the direct salaries to account for fringe benefits, overhead and payroll taxes.
- 34. Health Physics technicians used during vessel and internals removal will be supplied by DAEC staff.
- 35. DGC staff salaries, including overhead and profit, were determined by EnergySolutions and represent EnergySolutions' standard assumptions for these rates.
- 36. The professional personnel, used for the planning and preparation activities, and DGC personnel are assumed to be paid per diem at the rate of $114/day based on per diem rates in CONUS for Des Moines, Iowa.
- 37. Craft labor rates, for labor categories not furnished by FPLE, have been taken from the 2008 RS Means Labor Rates for the Construction Industry (Ref. No. 12), for Des Moines, Iowa. Since the skilled laborers are assumed to be supplied by the local union hall they will not be paid per diem.
- 38. This study has considered the impact of the September 11, 2001 terrorist attack on security force staffing and requirement. The security guard force included in this estimate has been sized accordingly.
- 39. This study follows the occupational exposure principles of As Low As Reasonably Achievable (ALARA) through the use of productivity loss factors that incorporate such items as the use of respiratory protection and personnel protective clothing. These factors increase the work duration and cost.
- 40. The costs of all required safety analyses and safety measures for the protection of the general public, the environment, and decommissioning workers are included in the cost estimates. This reflects the requirements of:

Decommissioning Cost Estimate Study Document No. 82A9634 for the Duane Arnold Energy Center Revision 0 6.0 STUDY RESULTS BY SCENARIO The study results for the four scenarios analyzed are presented in the following sections. 6.1 Scenario 1 - Base Case This scenario is based on the following:
" DECON methodology.
" No license extension, with shutdown on February 21, 2014.
" Terminate spent fuel pool operation five years after permanent unit shutdown.
" Spent fuel will be stored at the existing ISFSI.
- Class B and C waste will be temporarily stored in an on-site interim waste storage facility to be built during decommissioning. Class B and C waste are assumed to be stored on-site until 2025, which is the assumed date a licensed facility would be available to receive these wastes.
" The DOE Yucca Mountain repository, or other approved method of spent fuel disposition, will be available starting in 2025.
Spent Fuel Shipping Schedule The spent fuel shipment schedules for each scenario are based on information from FPLE and are also based, in part, on the DOE's "Acceptance Priority Ranking & Annual Capacity Report," dated July 2004 (Ref. No. 11). Spent fuel shipping schedules for each scenario are provided in Appendix B. The schedule for Scenario 1 includes the disposition of 2 GTCC waste containers. Spent fuel shipments to the DOE repository from the spent fuel pool will begin in 2027. In 2011, 610 spent fuel assemblies will be transferred to MPCs as required to maintain full-core off-load capacity. All spent fuel and GTCC will be removed from the ISFSI by 2054. Cost and Schedule Figure 6-1 is a summary project schedule. A detailed schedule is provided in Appendix C. Table 6-1 summarizes the period durations and total costs, including contingency, for License Termination, Spent Fuel, and Greenfield activities. A detailed cost table is provided in Appendix D, and a table of annual cash flows is provided in Appendix E. Appendix F provides an annual cash flow with the costs broken out by Labor, Equipment & Materials, Waste, Other, and Contingency categories. Project Staffing This scenario is based on the assumption that decommissioning will be performed by an experienced and qualified DGC, with oversight and management of the decommissioning, operations performed by DAEC staff. DAEC staffing levels, by organizational department and function, for each period are provided in Table 6-2. The DGC staffing levels, by organizational department and function, for each period are provided in Table 6-3. Page 33 of 58

Decommissioning Cost Estimate Study Document No. 82A9634 for the Duane Arnold Energy Center Revision 0 6.2 Scenario 2 - Base Case, Except SAFSTOR This scenario is identical to Scenario 1 (the Base Case) with the exception that the decommissioning alternative is a SAFSTOR rather than DECON methodology, and Class B and C waste generated during operations and SAFSTOR preparations will be stored in the existing Low Level Radwaste Storage Building until 2025, which is the assumed date a licensed facility would be available to receive these wastes. Spent Fuel Shipping Schedule The spent fuel shipping schedule for Scenario 2 is identical to Scenario 1. Due to the decay of activation products in the reactor internals over the SAFSTOR dormancy no GTCC waste is generated in this scenario. Cost and Schedule Figure 6-2 is a summary project schedule. A detailed schedule is provided in Appendix C. Table 6-5 summarizes the period durations and total costs, including contingency, for License Termination, Spent Fuel, and Greenfield activities. A detailed cost table is provided in Appendix D, and a table of annual cash flows is provided in Appendix E. Appendix F provides an annual cash flow with the costs broken out by Labor, Equipment & Materials, Waste, Other, and Contingency categories. Project Staffing This scenario is based on the assumption that decommissioning will be performed by an experienced and qualified DGC, with oversight and management of the decommissioning operations performed by DAEC staff. DAEC staffing levels, by organizational department and function, for each period are provided in Table 6-6. The DGC staffing levels, by organizational department and function, for each period are provided in Table 6-7. Waste Disposal Volumes Waste disposal is a significant element of the decommissioning project. The estimated cubic feet of waste are summarized as follows: Class A 379,944 Class B 1,287 Class C 884 Waste disposal volumes and costs, itemized by packaging, transportation, surcharges and disposal costs by waste class and facility, are provided in Table 6-8. The waste disposal cost provided in Table 6-8 does not include contingency. Page 40 of 58

Decommissioning Cost Estimate Study Document No. 82A9634 for the Duane Arnold Energy Center Revision 0 6.3 Scenario 3 - Base Case, Except License Extension This scenario is identical to Scenario 1 (the Base Case) with the exception of a 20 year license extension, and therefore no on-site interim waste storage facility is required for Class B and C waste. All legacy Class B and C waste generated during operations, and stored until a licensed facility is available to accept these wastes, is assumed to be disposed of during operations. Spent Fuel Shipping Schedule The spent fuel shipping schedule for Scenario 3 is provided in Appendix B. It includes the disposition of 2 GTCC waste containers. Spent fuel shipments to the DOE repository from the spent fuel pool will begin in 2027. During operations 1,281 spent fuel assemblies will be transferred to MPCs as required to maintain full-core off-load capacity. All spent fuel and GTCC will be removed from the ISFSI by 2067. Cost and Schedule Figure 6-3 is a summary project schedule. A detailed schedule is provided in Appendix C. Table 6-9 summarizes the period durations and total costs, including contingency, for License Termination, Spent Fuel, and Greenfield activities. A detailed cost table is provided in Appendix D, and a table of annual cash flows is provided in Appendix E. Appendix F provides an annual cash flow with the costs broken out by Labor, Equipment & Materials, Waste, Other, and Contingency categories. Project Staffing Staffing levels for each period of this case are the same as for Scenario 1. DAEC staffing levels, by organizational department and function, for each period are provided in Table 6-2. The DGC staffing levels, by organizational department and function, for each period are provided in Table 6-3. Waste Disposal Volumes Waste disposal is a significant element of the decommissioning project. The estimated cubic feet of waste are summarized as follows: Class A 377,596 Class B 1,866 Class C 540 GTCC 128 Waste disposal volumes and .costs, itemized by packaging, transportation, surcharges and disposal costs by waste class and facility, are provided in Table 6-10. The waste disposal cost provided in Table 6-10 does not include contingency. Page 47 of 58

Decommissioning Cost Estimate Study Document No. 82A9634 for the Duane Arnold Energy Center Revision 0 6.4 Scenario 4 - Base Case, Except SAFSTOR and License Extension This scenario is identical to Scenario 2 with the exception of a 20 year license extension, and therefore no on-site interim waste storage facility is required for Class B and C waste. Identical to Scenario 3 all legacy Class B and C waste generated during operations, and stored until a licensed facility is available to accept these wastes, is assumed to be disposed of during operations. Spent Fuel Shipping Schedule The spent fuel shipping schedule for Scenario 4 is identical to Scenario 3. Due to the decay of activation products in the reactor internals over the SAFSTOR dormancy no GTCC waste is generated in this scenario. Cost and Schedule Figure 6-4 is a summary project schedule. A detailed schedule is provided in Appendix C. Table 6-11 summarizes the period durations and total costs, including contingency, for License Termination, Spent Fuel, and Greenfield activities.
