SUMMARY
This report presents the costs for (1) decommissioning Duane Arnold Energy Center (DAEC) to the extent required to terminate the plant's operating license pursuant to 10 Code of Federal Regulations (CPR) 50.75(c), and (2) Independent Spent Fuel Storage Installation (ISFSI)
Decontamination and Demolition (D&D) pursuant to 10 CPR 72.30.
DAEC is 70% owned by NextEra Energy Duane Arnold, LLC. 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.
The estimate 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.
1). 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. 2). The estimate is based on compliance with current regulatory requirements and proven decommissioning technologies.
NRC requirements, set forth in Title 10 of the CPR, differentiate between the post-shutdown costs associated with storage of spent fuel on site and those associated with the decommissioning of the facility. 10 CPR 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 CPR 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 restores the site to either "Brownfield" or "Greenfield" conditions depending on the desired end-state. 10 CPR 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."
This DCE analyzes the following scenario, as defined by DAEC:
60 Year SAFSTOR, 2030 DOE Acceptance, Dry Fuel Storage
- Shutdown on October 30, 2020.
- Termination of spent fuel pool operation approximately four years after permanent shutdown.
- Following shutdown Phase II and III of the ISFSI will be constructed and all spent fuel will be transferred to Multi-Purpose Canisters (MPCs) for interim storage.
- SAFSTOR methodology, with decommissioning completed within 60 years of shutdown.
- Decommissioning will be performed by the utility staff and a Decommissioning General Contractor (DGC).

The estimate is based on site-specific plant systems and buildings inventories. 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," and "ISFSI D&D." The summary: schedule is shown in Figure 1-1 and may also be found in Section 6.0 of this report.

2.0 INTRODUCTION
2.1 Study Objective This report presents the costs for (1) decommissioning Duane Arnold Energy Center (DAEC) to the extent required to terminate the plant's operating license pursuant to 10* Code of Federal Regulations (CFR) 50.75(c), and (2) Independent Spent Fuel Storage Installation (ISFSI)
Decontamination and Demolition (D&D) pursuant to 10 CFR 72.30.
DAEC is 70% owned by NextEra Energy Duane Arnold, LLC. The other owners of DAEC are Central Iowa Power Cooperative (20%) and Com Belt Power Cooperative (10% ). All numbers presented in this report are on a 100% basis.
The estimate 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.
1). 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. 2). The estimate is based on compliance with current regulatory requirements and proven decommissioning technologies.
This DCE analyzes the following scenario, as defined by DAEC:
60 Year SAFSTOR, 2030 DOE Acceptance, Dry Fuel Storage
- Shutdown on October 30, 2020.
- DAEC' s spent fuel shipping schedules based on a 2030 start date for DOE' s acceptance of.spent fuel.
- Termination of spent fuel pool operation approximately four years after permanent shutdown.
- Following shutdown Phase II and III of the ISFSI will be constructed and all spent fuel will be transferred to Multi-Purpose Canisters (MPCs) for interim.
- SAFSTOR methodology, with decommissioning completed within 60 years of shutdown.
- Decommissioning will be performed by the utility staff and a Decommissioning General Contractor (DGC).
2.2 Regulatory Framework Provisions of current laws and regulations affecting decommissioning, waste management, and spent fuel management are as follows:
- 1. NRC regulations require a license for on-site storage of spent fuel. Wet storage in a spent fuel pool is authorized by a facility's 10 CFR Part 50 license. On-site dry storage of spent fuel at an Independent Spent Fuel Storage Installation (ISFSI) is licensed by either: (a) the general license set forth in 10 CFR 72.210, which requires that a Part 50 license be in place; or (b) a site-specific ISFSI license issued pursuant to 10 CFR Part 72.
4
2018 License Termination and ISFSI D&D Cost Document No. 164053-DC~-025 Estimate for the Duane Arnold Energy Center RevisionO
- 2. 10 CPR 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 CPR 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 CPR 72.30 (b) requires that a licensee under Part 72 must submit a decommissioning funding plan that contains information that provides assurance that funds will be available to decommission the ISFSI.
Decommissioning Alternatives The three 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 operation.
- 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 entombmenfwill 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 comments.
Post-Shutdown Spent Fuel Management Alternatives 5
2018 License Termination and ISFSI D&D Cost Document No. 164053-DCE-025 Estimate for the Duane Arnold Energy Center RevisionO Selection of a decommissioning strategy* and the associated schedule for completion is in part contingent upon an assumed start date for DOE acceptance of spent fuel and an assumed end date for completion of the transfer of all spent fuel assemblies projected to be generated during a power reactor's operating life. The basic options for long-term post-shutdown spent fuel management currently available to power plant operators are (1) wet storage consisting of continued maintenance and operation of the spent fuel pool, and (2) dry storage consisting of transfer of spent fuel from the fuel pool to on-site dry storage modules after a cooling period.
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 additional capital expenditures for purchase and construction of the ISFSI and dismantlement and disposal of the ISFSI following completion of spent fuel transfer to DOE. In both cases the decommissioning and spent fuel management costs are significantly affected by the assumed start and end dates for DOE acceptance of spent fuel.
In January 2013, DOE released its "Strategy for Management and Disposal of Used Nuclear Fuel and High Level Radioactive Waste" (Ref. No. 4). The DOE Strategy contemplates building the capability to begin executing DOE's commitment to address waste disposal within the next ten years. Under this Strategy, by 2021, operation would begin of a "pilot storage facility" with an "initial focus on accepting spent fuel from shutdown reactor sites." By 2025, a "larger interim storage facility" would be available, and by 2048, a geologic repository would commence operations.
For purposes of this DCE, DAEC has conservatively assumed that the larger interim storage facility is delayed five years and commences operations in 2030. DAEC has further assumed that the DOE acceptance rate is consistent with the 2004 "Acceptance Priority Ranking &
Annual Capacity Report" (Ref. No. 5), which is the most current information regarding acceptance of fuel.

2018 License Termination and ISFSI D&D Cost Document No. 164053-DCE-025 Estimate 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.
1). The cost model has been updated in accordance with regulatory requirements and industry experience. The cost model includes elements for estimating distributed and undistributed costs.
Distribut~d costs ar~ 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 DGC 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 on 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 Microsoft 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 tb differentiate between License Termination, Spent Fuel, Greenfield, and ISFSI D&D elements of the entire decommissioning scope of work, EnergySolutions has established a Work Breakdown Schedule (WBS) and cost accounting system to treat each element as a subproject.
7
2018 License Termination and ISFSI D&D Cost Document No. 164053-DCE-025 Estimate for the Duane Arnold Energy Center Revision 0 Accordingly, the overall project schedule is divided into interrelated periods with major milestones defining the beginning and ending of each period. The major milestones also serve as the basis for integrating the periods of the four subprojects.
3.3 Decommissioning Staff A site-specific staffing plan was developed by DAEC and EnergySolutions based on the existing DAEC operational staff and the assumption that the decommissioning will be performed by a DGC, with oversight and management of the DGC 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. The DAEC existing salary structure serves as the basis for calculating DAEC staff labor costs. The DGC salary costs are based on industry data.
Staffing levels for each project period are based on the AIF guidelines and industry experience.
The sizes of the DAEC and DGC staffs are varied in each period in accordance with regulatory requirements and work activities.
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 e.xisting rate structures to estimate disposal costs of these wastes. The approach used in this DCB to estimate 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, LLRW disposal is controlled by NRC regulation 10 CPR 61, which went into effect December, 1983. This regulation stipulates the criteria for the establishment and operation of shallow-land LLRW burial facilities. Embodied within this 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 CPR 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 CPR 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. After performing 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 CPR 61.
The classification of LLRW resulting from decommissioning activities is based on AIF/NESP-036 (Ref. No. 1) and NUREG/CR-0672 for Boiling Water Reactors (BWRs) (Ref. No. 7), and 8
2018 License Termination and ISFSI D&D Cost Document,No.164053-DCE-025 Estimate for the Duane Arnold Energy Center Revision 0 recent industry experience. The estimated curie content of the reactor vessel and internals at shutdown is derived from NUREG/CR-0672 and adjusted for the different mass of components as well as the 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 the following constraints: curie content, dose-rate, container weight limit, or container volume limit. GTCC waste from segmentation of the reactor vessel internals is packaged in MPCs. - 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.
Transportation Transportation routes to processing and di~posal facilities are determined based on available transportation modes (truck, rail, barge, or combinations). Transportation costs for the selected routes and mode_s are obtained from vendor quotes or published tariffs whenever possible.
Class A Disposal Options and Rates In accordance with the existing LOP 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 three operational commercial disposal facilities licensed to accept Class B and C LLRW: the Barnwell facility~ operated by EnergySolutions in Barnwell, South Carolina; the U.S. Ecology facility in Richland, Washington; and the facility in Andrews County, Texas operated by Waste Control Specialists.
Barnwell only accepts waste from states within the Atlantic Compact, and U.S. Etology only accepts waste from states within the Northwest and Rocky Mountain Compacts. However, the WCS facility will accept waste froin the Texas Compact (comprised of Texas and Vermont) and non-Compact generators. The Texas Compact Commission on March 23, 2012 approved amendments to rules allowing the import of non-compact generator LLRW for disposal at the Andrews County facility.
Greater Than Class C (GTCC)
Wastes identified as 10 CFR 61 Class A, B, and ,c may be disposed of 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 CPR 61, these components 9
2018 License Termination and ISFSI D&D Cost. Document No. 164053-DCE-025 Estimate for the Duane Arnold Energy Center Revision 0 cannot be disposed of in a near-surface LLRW disposal facility and must b.e 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 CPR 61 Class C limitations. The courts have held that DOE is obligated to accept and dispose of GTCC and, therefore, this estimate assumes that the DOE will accept this waste along with spent fuel. Although there may be no additional costs for DOE disposal of GTCC, this estimate conservatively assumes a GTCC waste disposal cost. This estimate further assumes that the GTCC waste will be packaged in DSCs and will be shipped to a storage or disposal facility by DOE along with the spent fuel at a shipping costs equivalent to the commercial cost of shipping a Type B licensed, shielded cask such as the CNS 8-120B cask.
LLRW Volume Reduction Based on current Class A LLRW disposal rates on-site volume reduction techniques such as waste compaction or an aggressive decontamination, survey and release effort are not currently considered to be cos{effective over disposal.
Non-Radioactive Non-Hazardous Waste Disposal EnergySolutions assumes that recyclable, non-radioactive scrap metal resulting from the decommissioning program will be transported to a scrap metal dealer. However, no credit is assumed in the estimate for the value of the scrap metal. 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. Asphalt from parking lots and roadways is assumed to be stockpiled on site and removed, at no cost to the project, by a recycler. All other demolition debris is removed from th~ site and disposed of at a local construction debris landfill.
Hazardous and Industrial Waste Disposal Lead shielding remaining after shutdown is assumed to be removed from its installed locations and disposed of as a mixed waste. In accordance with information furnished by DAEC thirty percent of insulated systems in radiologically controlled areas are assumed to contain asbestos, therefore; this DCE includes a line item for asbestos abatement. The decommissioning estimate also includes an estimate for hazardous and industrial waste disposal based on information provided by DAEC. The cost of hazardous and industrial waste disposal includes DAEC' s estimated cost for closure of Resource Conservation and Recovery Act (RCRA) storage areas.
Additionally, surfaces coated with lead based paint will be remediated as required for demolition.
3.5 Final Status Survey The cost of performing a final status survey (PSS) 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 PSS activity cost calculation includes th~ in-place remote 10
2018 License Termination and ISFSI D&D Cost Document No. 164053-DCE-025 Estimate for the Duane Arnold Energy Center Revision 0 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-036 "Guidelines for Producing Nuclear Plant Decommissioning Cost Estimates" (Ref. Nb. 1). The AIF guideline identifies contingencies for activities specific to a nuclear power plant decommissioning, such as reactor internals removal. The contingencies presented in the AIF guideline are based on the assumption that the estimated costs are not well known; therefore, the recommended contingencies are greater than they would be if the estimated costs were well known. With the exception of the system decontamination, reactor vessel and reactor internals removal, and disposal, the contingencies presented in the AIF guideline 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 recommended in the AIF guideline 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.
This estimate applies site-specific contingency factors to each WBS element based on industry practices. The contingencies rates applied in this estimate are specific to decommissioning estimates consistent with information presented in AIF guideline and DOE G. The 11
2018 License Termination and ISFSI D&D Cost Document No. 164053-DCE-025 Estimate for the Duane Arnold Energy Center Revision 0 decommissioning costs generated in the estimate are considered well known and, as such, the contingencies presented in AIF guideline 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 has been used in preparing this estimate. This allows for additional reduction in contingency costs. The following table provides a summary of contingency values applied in this estimate where the plant structures, systems, and major component material inventories are well defined,'as with this study.
Package Material & Ship&
Category Labor Egui2ment Bury Other Engineering 13%
Contaminated components/Concrete 23% 23% 23%
Clean components 13% 13% 13%
Reactor Vessel and Reactor Internals 50% 23% 25%
Other 15%
The above contingency categories address the difference in uncertainty associated with performance of the work. In the case of a power plant decommissioning project, the segmentation of the reactor internals and pressure vessel and removal of radiologically contaminated plant systems and structures have the highest degree of uncertainty and are therefore assigned the higher contingency rates.
- 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 0th.er 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 third party HP staff are calculated and reported as an undistributed line item. A line item specific contingency is then calculated for each activity cost element.

2018 License Termination and ISFSI D&D Cost Document No. 164053-DCE-025 Estimate 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 archit~ct engineer and constructor.
The unit was originally designed, analyzed, and licensed for a steady-state core power of 1,658 MWt, although the plant Technical Specifications restricted operation to a rated power of 1,593 MWt. In 1985, the Technical Specifications were amended to allow the DAEC to operate at a steady-state power level of 1,658 MWt (License Amendment #115). Then, in 2001, the rated power level was increased again to 1,912 MWt (License Amendment #243): The current' shutdown date is October 30, 2020.
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 2,411 assemblies.
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 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 SAFSTOR The project periods for SAFSTOR consist of eleven License Termination periods, seven Spent Fuel Management periods, two Greenfield periods, and two ISFSI D&D periods. 'fhe ,project periods defined for this site-specific study and the major activities performed during each period are as follows:

It is also assumed that the DAEC staff will be supplemented by professional consulting engineering, particularly in the planning and preparation phase. The sizes of the staffs are varied iii each period 'in accordance with regulatory requirements and the work activities. Details on the staff levels during each period are provided in Section 6.0.
4.4 Spent Fuel Shipments .
The spent fuel shipping schedule was provided by DAEC. The spent fuel shipping schedule is based on the DOE 2004 "Acceptance Priority Ranking & Annual Capacity Report" (Ref. No. 5).
The spent fuel shippi~g scheduie is provided in Appendix B.
15
2018 License Termination and ISFSI D&D Cost Document No. 164053-DCE-025 Estimate for the Duane Arnold Energy Center RevisionO 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 2018 or has been escalated to 2018 dollars. To{als and subtotals have been rounded to significant figures.
- 2. The estimate is based on a shutdown date of October 30, 2020.
- 3. 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
, must be submitted to the NRC within 30 certificate of permanent cessation of operations . .
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. 90 days after the NRC rece1ves 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.
- 4. The decommissioning will be performed using currently available technologies.
- 5. The spent fuel shipping schedule assumes DOE begins accepting spent fuel in 2030.
- 6. The material inventory for this estimate is based on prior EnergySolutions' take-offs and has been updated, based on information furnished by DAEC, to reflect major structural modifications.
- 7. All transformers on site following shutdown are assumed to be polychlorinated biphenyl (PCB)-free; therefore, this estimate does not include costs for disposition of PCB contaminated transformers.
- 8. Cost for transportation of clean scrap metal to a recycler is included in the estimate; however, no credit is taken for the value of the scrap metal. A portion of the 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 concrete and demolition debris is removed from the site and disposed of at a local off-site construction landfill.
- 9. Lead shielding remaining after shutdown is assumed to be disposed of as a mixed waste.
- 10. A budget for hazardous material is included in the estimate, which is based on information provided by DAEC. 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.
16
2018 License Termination and ISFSI D&D Cost Document No. 164053-DCE-025 Estimate for the Duane Arnold Energy Center Revision 0
- 11. 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.
- 12. 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 30% of the insulation on contaminated and insulated piping will be asbestos and disposed of as Class A waste.
- 13. Costs for disposition of greater than Class A LLRW either currently stored on site or anticipated to be on site at the time of decommissioning are included in this estimate.
The types and quantities of greater than Class A LLRW were provided by DAEC, and include, but are not limited to the following expected to be stored in the spent fuel pool at the time of shutdown:
27 control blades 24 Local Power Range Monitors 25 blade guides 6 half blade guides
- 14. All Class A waste is assumed to be disposed of at EnergySolutions' facility in Clive, Utah, in accordance with the existing LOP Disposal Agreement between EnergySolutions and DAEC (Ref. No. 8).
- 15. DAEC furnished Class Band C waste disposal rates.
- 17. GTCC waste generated from the segmentation of the reactor internals will be packaged in MPCs. In this estimate, the MPCs are assumed to be accepted by DOE at the time of the deferred decommissioning.
- 18. Vessel and internals curie estimates were derived from the values for the Reference BWR vessel and internals in NUREG/CR-0672 (Ref. No. 7) and adjusted for mass and the SAFSTOR decay period.
- 19. The site-specific classification of radioactive wastes for DAEC identified one components within the reactor vessel (the Core Shroud) will exceed Class C limitations.
Two NUHOMs MPCs are assumed to be required and DAEC provided the estimated costs.
- 20. Spent fuel will remain in the spent fuel pool for approximately four years before being transferred to the ISF~I.
- 21. The ISFSI pad and HSMs are assumed to have no activated concrete or surface contamination.
17
2018 License Termination and ISFSI D&D Cost Document No. 164053-DCE-025 Estimate for the Duane Arnold Energy Center RevisionO
- 22. The 10 CFR Part 50 .license will be maintained until DOE has taken possession of the spent fuel.
- 23. Environmental Permits costs are based on data furnished by DAEC and were adjusted to meet the requirements of each period.
- 24. An estimate of the annual property taxes was furnished by DAEC and included in the estimate.
- 25. Annual NRC 10 CFR 171.15 fees, for reactors in decommissioning, of $198,000 are included in the estimate. ,
- 26. The estimate includes annual NRC inspection fees during each decommissioning period based on the type and level of activities being performed along with NRC review fees for license amendment requests, exemption requests and the License Termination Plan based on NRC's hourly rate of $275 per hour.
- 27. Annual operating insurance premiums were supplied by DAEC. The premium amounts were adjusted to meet the requirements of each period based on information provided by DAEC.
- 28. DAEC provided an annual allowance for miscellaneous materials and services to account for costs such as communications, miscellaneous utilities and services, office supplies, and consumables not captured elsewhere in the estimate.
- 29. DAEC staff positions and average burdened salary data were supplied by DAEC and accou:11t for fringe benefits, overhead and payroll taxes.
- 30. DGC staff salaries, including overhead and profit, were determined by EnergySolutions and represent EnergySolutions' standard assumptions for these rates
- 32. The current utility staff size is considered to be sufficiently stable to remain virtually unchanged to end of life. For this reason, the utility staff is assumed to be the same size at the time of shutdown.
- 33. The professional personnel used for the planning and preparation activities are assumed to be paid per diem at the rate of $93/day, based on per diem rates from U.S. General Services Administration (GSA) for Cedar Rapids, Iowa.
- 34. Craft labor rates were furnished by DAEC. Craft labor rates for disciplines not furnished by DAEC have been taken from the 2018 RS Means Labor Rates for the Construction Industry (Ref. No. 11), for Cedar Rapids, Iowa. Since the skilled laborers are assumed to be supplied by the local union hall, they will not be paid per diem.
- 35. The security guard force included in this DCE is in accordance with NRC security regulations as implemented by an NRC approved security plan and anticipated 18
2018 License Termination and ISFSI D&D Cost Document No. 164053-DCE-025 Estimate for the Duane Arnold Energy Center Revision 0 amendments to that plan applicable during each decommissioning period following shutdown.
- 36. This study follows the occupational exposure principles of As Low As Reasonably Achievable (ALARA) through the use of productivity loss factors that incorporate sueµ items as the use of respiratory protection and personnel protective clothing. These factors increase the work duration and cost.
- 37. 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:
10CFR20 Standards for Protection Against Radiation 10 CFR50 Domestic Licensing of Production and Utilization Facilities 10 CFR61 Licensing Requirements for Land Disposal of Radioactive Waste 10 CFR 71 Packaging of Radioactive Material for Transport 10 CFR 72 Licensing Requirements for the Independent Storage of Spent Nuclear Fuel and High-Level Radioactive Waste 29 CFR 1910 Occupational Safety and Health Standards 49 CPR 170-189 Department of Transportation Regulations Governing the Transport of Hazardous Materials Reg. Guide 1.159 Assuring the Availability of Funds for Decommissioning Nuclear Reactors
- 38. Activity labor costs do not include any allowance for delays between activities, nor is there any cost allowance for craft labor retained on site while waiting for work to become available.
