2008 Decommissioning Cost Update for the Document No. 82A9641 Millstone Nuclear Power Plant, Unit 1 Revision 1 1.0 EXECUTIVE

SUMMARY

This report presents an update, to the 2006 Decommissioning Cost Estimate Study. of the Millstone Nuclear Power Plant (Ref. No. 1), hereinafter referred to as the 2006 Cost Study. The Millstone Nuclear Power Plant (Millstone) is owned by Dominion Virginia Power (Dominion).

Specifically, this report provides an economic and technical update for Millstone Unit I (Unit 1).

This update has been performed to furnish an estimate, for financial planning purposes, of the costs for (1) decommissioning Millstone Unit 1 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.

.2).

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. 3).

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. 4). 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 5075(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.

This study Was initiated and completed based on a Yucca Mountain opening date of 2020 in accordance with the July 15, 2008 congressional testimony of Edward Sproat, DirectOr Office of Civilian Radioactive Waste Management, DOE. On March 5, 2009, Energy Secretary Steven Chu testified to the U.S. Senate that Yucca Mountain is no longer an option for spent fuel management.

This announcement came days before the issuance of this final report for Millstone Unit 1. The spent fuel management costs presented herein,are based on the facts that the DOE has not Withdrawn the license application for Yucca Mountain before the NRC and the Nuclear Waste Policy Act obligates the federal. government to accept used fuel from commercial reactors regardless of the status of Yucca Moutfitain. Therefore, EnergySolutions considers any Page. 5 of 45

2008 Decommissioning Cost Update for the Document No. 82A9641 Millstone Nuclear Power Plant, Unit 1 Revision 1 revision of the spent fuel management assumptions, upon which this study is based, to be premature as of the date of issuance. of this study.

This study analyzes three scenarios, defined by Dominion, as follows:

Scenario I - Base Case 0 Unit 1 is currently in modified SAFSTOR.

0 SAFSTOR Unit 2 when it is permanently shutdown in 2035;, DECON Units 1, 2 and 3 as a group only after Unit 3 is permanently shutdown in 2045.

0 Unit 1 spent fuel will remain in wet storage until acceptance by the DOE.

• Unit 1 will be converted to a passive SAFSTOR configuration following the completion of spent, fuel shipping.

• Terminate Unit 2 spent fuel pool operation eight years after permanent shutdown.

• Terminate Unit 3 spent fuel pool operation ten years after permanent shutdown.

• Spent fuel from Units 2 and 3 will be stored in Multi-Purpose Canisters (MPCs) at an on-site Independent Spent Fuel Storage Installation (ISFSI), a portion of which has already been constructed.

• A dry transfer facility will not be necessary.

M Yucca Mountain spent fuel repository opens in 2020.

Decommissioning will be performed by Dominion and a Decommissioning General Contractor (DGC).

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 previoutsly, by cost account "License Termination," "Spent Fuel Management," or "Greenfield." The summary schedule for Scenario I 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 an update to the 2006 Decommissioning Cost Estimate Study ofr the Millstone Nuclear Power Plant (Ref. No. 1), hereinafter referred to as the 2006 Cost Study. The Millstone Nuclear Power Plant (Millstone) is owned by Dominion Virginia Power (Dominion).

Specifically, this report provides an economic and technical update to Scenario 4 of the 2006 Cost Study (2006 Scenario 4) for Millstone Unit I (Unit 1).

This update has been performed to furnish an estimate, for financial planning purposes, of the costs for (1) decommissioning Millstone Unit 1 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.

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 Independent Spent Fuel Storage Installation (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.

21 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, occu'rs 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 96.1 (Ref. No. 5), 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 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, Page 12 of 45

2008 Decommissioning Cost Update for the Document No. 82A9641 Millstone Nuclear Power Plant, Unit 1 Revision 1 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 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' 20201.

However, there is considerable uncertainty associated with this scheduled opening. Per guidance from Dominion, this study assumes that the DOE Yucca Mountain 'repository,, or other approved

-method of spent fuel disposition, will be.available starting in 2020. 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 thedate of this study.

The selection of a spent fuel management alteirnati've. 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.

2008Decommissioning Cost Update for the Document No. 82A9641 Millstone Nuclear Power Plant, Unit 1 Revision 1 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.

3). 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 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 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 actiyity. For exafiple, 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 WBS and c6st accounting system to treat each element as a subproject.

Accordingly, the ýoverall project schedule is, divided into interrelated periods with major milestones definiing the beginning and Page 15 of 45"

2008 Decommissioning Cost Update for the Document No. 82A9641 Millstone Nuclear Power Plant, Unit 1 Revision 1 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 that 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 the Utility staff. It is also assumed that the Utility staff will be supplemented by professional consulting engineering, particularly in the planning and preparation phase.

EnergySolutions. analyzed the Millstone operational staff and developed a site-specific staffing plan.

The Dominion existing salary structure was then used as the basis for calculating Utility 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, Atomic Industrial Forum (AIF)guidelines and industry experience. The sizes of the staffs are varied in each period in accordance with the requirements of the work activities.

Staffing has been organized into the following departments or functional groups:

• Health Physics

• Management

2008 Decommissioning Cost Update for the Document No. 82A9641 Millstone Nuclear Power Plant, Unit 1 Revision 1 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 CFR 61, 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. 3), NUREG/CR-0130 (Ref. No. 6), NUREG/CR-0672 (Ref. No. 7),

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, andreactor 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 thecask owners and operators.

Transportation Transportation routes to processing and disposal facilities are determined based on :available transportation modes (truck, rail, barge or combinations). Routes and distances are detemined

,using the Transportation Routing Analysis Geographic..Information System (TRAGIS) software

.deyeloped by the OakRidge National*Laboratory National Transportation Research' Center (Ref.

No. 8).

Class A Disposal Options and Rates

'p All reported waste disposal costs include packaging, transportation, and any applicable E

surcharges.

Class B and C Disposal Options and Rates Currently, within the United States, there are only two operational 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. Additionally, as of January,. 2009, the Texas Commission on Environmental Quality (TCEQ) issued Waste Control Specialists LLC (WCS) a final license for the near-surface disposal of Class A, B, and C LLRW at their site in Andrews County, Texas. The LLRW portion of this site is expected to be operational in' 2010. However, Barnwell only accepts: waste from states within the Atlantic Compact, U.S.- Ecology only accepts, waste from states within the Northwest and Rocky Mountain Compacts, and the WCS facility will only accept waste from the Texas Compact (comprised of Texas and Vermont).

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 sifes 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 t :go? 'Since the cost estimate 'is based on current or present day dollars, the disposal cost for,ClIss 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. EnergySoluiions has reviewed several studies developed' in an attempt to quahtiIfy Ithe disposal. costs associated with a new disposal facility cponstructed in today',s environment. Based 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 Page 18 of 45

2008 Decommissioning Cost Update for the Document No. 82A9641 Millstone Nuclear Power Plant, Unit 1 Revision 1 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 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 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, stored in either 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 8-1 20B cask, which is owned and operated by EnergySolutions.

LLRW Volume, Reduction Based on current Class A LLRW disposal rates, EnergySolutions does not assume on-site volume reduction techniques, such as waste compaction or an aggressive~decontamination, survey and release effort.

'These 'activities are not currently considered to, be cost 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 dealerý AHowiever, 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 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 maiterial. The entities receive the lead at no charge in: return for providing the removal and shipping services.. Non-Radioactive contaminated surfaces coated with lead based paint will-be removed as non-.

hazardous building demolition debris. All other chemicals *and hazardous materials -present, at Page 19'of 45

2008 Decommissioning Cost Update for the Document No. 82A9641 Millstone Nuclear Power Plant, Unit 1 Revision 1 shutdown are assumed to beý removed and, disposed. by the plant staff prior to decommissioning as a normal,part of plant operations.

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. 10).

Estimates of MARSSIM Class 1, 11 and I1l survey designations are based on radiological characterization data furnished by Dominion and assumptions regarding, contamination resulting from small and large component removal activities. The FSS activity ýcost 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. 11): 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 appliedto each estimatebased 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.20-30r Budget Estimate 15-25 Title I (Preliminary Design Estimate) 10-20 Title II (Definitive Design Estimate) 5415 EnergySolutions' approach to assigning appropriate contingency rates is based on adaptations of published values for the specific decommissioning activities. One source for such published ifnformation is AIF/NESP-036 "Guidelines for Producing Nuclear Plant Decornmissioningý Cost Estimaites" (Ref. No. 3).

This document identifies contingencies for 'activities specific to a nucle*r power plant dec0omissiohing, 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 Page 20 of 45

2008 Decommissioning.Cost Update for the Document No. 82A9641 Millstone Nuclear Power'Plant, Unit 1 Revision 1 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.

EnergySolutions has developed.contingencies specific' to decommissioning estimates utilizing the information presented in AlF 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..

A reactor decommissioning program will beKconducted 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 areý 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 the Utility HP staff are. calculated and' reported as an undistributed line item. A line item specific contingency isthen calculated for each activity cost.element, Page.'21 of 45

2008 Decommissioning Cost Update for the Document No. 82A9641 Millstone Nuclear Power Plant, Unit 1 Revision i 4.0 SITE SPECIFIC TECHNICAL APPROACH 4.1 Facility Description 4.1.1 General Site Description The Millstone Nuclear Power Station is a three unit site consisting of two operating PWR nuclear powered. electrical generating stations (Units 2 and 3) and one BWR(Unit 1) that is currently in modified SAFSTOR. The plant site comprises approximately 500 acres.

Millstone. Unit I is.a single-cycle BWR with, a General Electric Mark I containment. It had a reactor thermal output of 2,011 megawatts (MWt) and a net electrical output of 662 MWe. Millstone Unit I was permanently shut down on November 4, 1995. The current license expiration dates for Units 2 and 3 are: July 31, 2035 and November 25, ý2045, respectively.

Appendix A provides a list of the Millstone Unit 1 systems and structures included in the material inventory for this study.

4.1.2 Millstone Unit 1 SAFSTOR Status In accordance with "Millstone 1 Post Shutdown Decommissioning Activities Report,"

dated June 1999 (Ref. No. 12), activities required to place Unit I in a safe and efficient long term SAFSTOR condition have been implemented. The Millstone Unit 1 Reactor Cavity Decommissioning Project, was performed resulting in the completion of the following activities:

• An activation analysisýof the, reactor pressure vessel and internals was performed, resulting in the determination that. the interior grid portion of the top guide would, be characterized per 10 CFR. 61 requirements as GTCC waste at the. timeý of the planned,vessel disposal.

= Segmentation of the reactor vessel internals to remove the interiorgrid portion top guide removed was performed. The resulting GTCC waste is currently: stored in five canisters within the' fuel pool. The canisters were' designed to fit within a single NUHOMs MPC for future dry storage.

0 Following the internals segmentation, the moisture 'separator, steam dryer, and reactor head were reinstalled.

a Irradiated hardware, consisting primarily of 107 irradiated control rod blades arid 42 irradiated in-core instrumentation assemblies, has been disposed of at Barnwell.

m All irradiated and non-irradiated Special Nuclear Material (SNM). has been disposed of at Barnwell.

a Cleanup of the spent fuel' pool involving removal and disposal of miscellaneous irradiated hardware 'and, filters has been completed.

" The spent fuel pool has been permanently isolated from the reactor cavity by installation of a closure gate.

0 The reactor cavity and vessel were drained and a radiation shielding package was installed on the reactor head.

" Radioactive sludge from the Cleanup Filter Sludge Receiver Tank and Reactor Building Equipment Drain Tank was removed and disposed of.

" Vessels containing radioactive zeolite and charcoal from the Xenon-Krypton Building were removed and disposed of.

4.1.3 Independent Spent Fuel Storage Installation Millstone has an existing ISFSI that consists of a reinforced concrete pad, nominally:25 feet by 180 feet, with a 20-foot ramp on one side for vehicle access. The concrete pad is contained within a fenced high-security area. Currently, there are eight (8) MPCs housed in precast reinforced concrete Horizontal Storage Modules (HSMs) in storage.

The existing pad has the capacity to store an additional twelve (12) MPCs. The ISFSI is operated under the 10 CFR Part 72 general license using the manufacturer's Certificate of Compliance.

4.2 Decommissioning Periods The project periods defined for Scenario 1 maintain Unit I in its current modified SAFSTOR condition until Unit 3 has been permanently shut down. Then, following Unit 3 shutdown, Unit I will be decommissioned and the site will be restored to Greenfield conditions. There are five SAFSTOR periods, five: DECON periods, one SNF period and two Greenfield periods. The License Termination periods and Spent Fuel Management period occur simultaneously; The Greenfield periods follow the License Termination periods sequentially, with some overlap. The project periods defined for this site-specific study and the major activities performed during each period, are as follows:

2008 Decommissioning Cost Update for the Document No. 82A9641 Millstone Nuclear Power Plant, Unit I Revision 1 6.0 STUDY RESULTS BY SCENARIO The study results for the three scenario analyzed are presented in this section.

6.1 Scenario 1 - Base Case Scenario No. 1 is, based on the following:

" Unit I is maintained in modified. SAFSTOR until all spent fuel is accepted by DOE.

" At the completion of spent fuel shipping, Unit I is placed in, a passive SAFSTOR configuration.

" Decommissioning is delayed until Unit 3: is permanentlyshutdown in 2045 and the Unit 3 fuel pool emptied.

" All costs are revised. of escalatedfrom 2005 to 2008 dollars.

" LOP Disposal Rates are used for Class A LLRW.

" The Yucca Mountain spent fuel repository opens in 2020.

" Decommissioning will be performed by the Utility and a DGC.

Spent Fuel Shipping Schedule The spent fuel shipment schedule is-based on information from Dominion and also based, in part, on the DOE's "Acceptance Priority Ranking & Annual Capacity Report," dated July 2004 (Ref.

No. 13). The spent fuel shipping schedule is provided in Appendix B.

This scenario includes the disposition of one MPC :containing GTCC waste, Spent fuel shipments to the DOE repository from the spent fuel. pool will begin in 2020. All spent, fuel.and GTCC will be removed from the spent fuel pool by 2028.

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. The 10 CFR Part 50 license for Unit 1 is terminated by 2053, which is within the 60-year period allowed by the NRC.

A detailed cost table is provided in Appendix D, and a 'table of annual expenditures is provided in Appendix E.

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 the Utility staff.. Utility-staffing levels, by organizational depairment, 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 6-31.

Serial No.10-694 Docket No. 50-245 ATTACHMENT 3 MILLSTONE POWER STATION UNIT I APPLICATION FOR WITHHOLDING INFORMATION AND AFFIDAVIT OF LESLIE N. HARTZ DOMINION NUCLEAR CONNECTICUT, INC.

MILLSTONE POWER STATION UNIT 1

Serial No.10-694 Docket No. 50-245 10 CFR 2.390 APPLICATION FOR WITHHOLDING INFORMATION AND AFFIDAVIT OF LESLIE N. HARTZ I, Leslie N. Hartz, Vice President - Nuclear Support Services, of Dominion Nuclear Connecticut, Inc. state that:

1.

I am authorized to execute this affidavit on behalf of Dominion Nuclear Connecticut, Inc.

(DNC).

2.

At the request of the NRC, DNC is providing Revision 1 to the 2008 Decommissioning Cost Update for the Millstone Nuclear Power Plant, Unit 1 (MPS1 Study) dated June 23, 2009. The MPS1 Study contains proprietary commercial information that should be held in confidence by the NRC pursuant to the policy reflected in 10 CFR 2.390(a)(4) because:

a. This information is being held in confidence by DNC.

b. This information is of a type that is held in confidence by DNC, and there is a rational basis for doing so because the information contains sensitive commercial information.

c. This information is being transmitted to the NRC in confidence.

d. This information is not available in public sources and could not be gathered readily from other publicly available information.

e. Public disclosure of this information would create substantial harm to the competitive position of DNC by disclosing confidential contract information to other parties whose commercial interests may be adverse to those of DNC.

Therefore, the use of this confidential information by competitors may permit them to use the information to develop competitive advantages over DNC.

3. Accordingly, DNC requests that the designated document be withheld from public disclosure pursuant to the policy reflected in 10 CFR 2.390(a)(4).
