1.1 OBJECTIVES OF STUDY The objective of this study was to prepare estimates of the cost, schedule, and waste volumes generated to decommission TMI-2, including all areas affected by the March 1979 accident.Three decommissioning scenarios were evaluated for TMI-2. In each scenario decommissioning activities are coordinated with the adjacent operating unit (TMI-1 or Unit 1). The scenarios assume that Exelon Generation will be successful in extending the Unit 1 operating license to 2034. The three scenarios are also based upon the premise that decommissioning work at Unit 2 would not begin prior to final shutdown of Unit 1 in 2034, consistent with the agreement between Exelon and FirstEnergy. | |||

This scenario is subsequently referred to as"Delayed DECON." The second scenario assumes that TMI-1 is placed into safe-storage with decommissioning deferred 60 years. TMI-2 remains in storage with decommissioning deferred until it can be sequenced with TMI-1. This scenario is subsequently referred to as "Custodial SAFSTOR." The final scenario assumes that TMI-1 is promptly decommissioned upon the scheduled cessation of operations in 2034.

1.3.3 Radiological Criteria for License Termination In 1997, the NRC published Subpart E, "Radiological Criteria for License Termination,"[1 2] amending 10 CFR §20. This subpart provides radiological criteria for releasing a facility for unrestricted use. The regulation states that the site can be released for unrestricted use if radioactivity levels are such that the average member of a critical group would not receive a Total Effective Dose Equivalent (TEDE) in excess of 25 millirem per year, and provided that residual radioactivity has been reduced to levels that are As Low As Reasonably Achievable (ALARA).The decommissioning estimates for TMI-2 assume that the site will be remediated to a residual level consistent with the NRC-prescribed level."

The conceptual approach that the NRC has described in its regulations divides decommissioning into three phases. The initial phase addresses the transition of reactor operations (i.e., power production) to facility de-activation and closure. The second phase encompasses activities during the storage period or during major decommissioning activities, or a combination of the two. The third phase pertains to the activities involved in license termination. | The conceptual approach that the NRC has described in its regulations divides decommissioning into three phases.

SUMMARY
This report presents estimates of the cost to decommission the Three Mile Island, Unit 2 nuclear unit (TMI-2) for the selected decommissioning scenarios following the scheduled cessation of plant operations at the adjacent Unit 1 reactor. This analysis relies upon site-specific, technical information, originally developed in an evaluation for the GPU Nuclear Corporation in 1995-96,[1]
and first updated in 2003 for FirstEnergy.
1 2 1 The analysis has been further updated to reflect current assumptions pertaining to the disposition of the nuclear unit and relevant industry experience in undertaking such projects.
The updated estimates are designed to provide the FirstEnergy Corporation with sufficient information to assess its financial obligations, as they pertain to the eventual decommissioning of the nuclear unit.The decommissioning of TMI-2 is a continuation of the decontamination efforts started in the 1980s, following its accident.
The ultimate goal of the decommissioning is to remove the radioactive material from the site that would preclude its release for unrestricted use.The estimates are based on numerous fundamental assumptions, including regulatory requirements, project contingencies, radioactive waste disposal options, and site remediation requirements.
The estimates also include the dismantling of non-essential structures and limited restoration of the site.Alternatives and Regulations The Nuclear Regulatory Commission (NRC or Commission) provided initial decommissioning requirements in its rule adopted on June 27, 1988.[31 In this rule, the NRC set forth financial criteria for decommissioning licensed nuclear power facilities.
The regulations addressed planning needs, timing, funding methods, and environmental review requirements for decommissioning.
The rule also defined three decommissioning alternatives as being acceptable to the NRC: DECON, SAFSTOR, and ENTOMB.DECON is defined as "the alternative in which the equipment, structures, and portions of a facility and site containing radioactive contaminants are 1 "Decommissioning Cost Estimate for the Three Mile Island, Unit 2," Document No. G01-1196-003, TLG Services, Inc., February 1996.2 "Decommissioning Cost Estimate for Three Mile Island Unit 2," Document No. F07-1476-002, TLG Services, Inc., September 2004.3 U.S. Code of Federal Regulations, Title 10, Parts 30, 40, 50, 51,70 and 72 "General Requirements for Decommissioning Nuclear Facilities," Nuclear Regulatory Commission, Federal Register Volume 53, Number 123 (p 24018 et seq.), June 27, 1988.TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Page viii of xvi removed or decontaminated to a level that permits the property to be released for unrestricted use shortly after cessation of operations."[
4]SAFSTOR is defined as "the alternative in which the nuclear facility is placed and maintained in a condition that allows the nuclear facility to be safely stored and subsequently decontaminated (deferred decontamination) to levels that permit release for unrestricted use."[5 1 Decommissioning is to be completed within 60 years, although longer time periods will be considered when necessary to protect public health and safety.ENTOMB is defined as "the alternative in which radioactive contaminants are encased in a structurally long-lived material, such as concrete; the entombed structure, is appropriately maintained and continued surveillance is carried out until the radioactive material decays to a level permitting unrestricted release of the property."[1 6 As with the SAFSTOR alternative, decommissioning is currently required to be completed Within 60 years.The 60-year restriction has limited the practicality of the ENTOMB alternative at commercial reactors that generate significant amounts of long-lived radioactive material.
In 1997, the Commission directed its staff to re-evaluate this alternative and identify the technical requirements and regulatory actions that would be necessary for entombment to become a viable option. The resulting evaluation provided several recommendations, however, rulemaking has been deferred pending the completion of additional research studies, e.g., on engineered barriers.In 1996, the NRC published revisions to the general requirements for decommissioning nuclear power plants to clarify ambiguities and codify procedures and terminology as a means of enhancing efficiency and. uniformity in the decommissioning process. [71 The amendments allow for greater public participation and better define the transition process from operations to decommissioning.
Regulatory Guide 1.184, issued in July 2000, further described the methods and procedures acceptable to the NRC staff for implementing the requirements of the 1996 revised rule relating to the initial activities and major phases of the decommissioning process. The costs and schedules presented in this analysis follow the general guidance and processes described in the amended regulations.

Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Page ix of xvi Decommissioning Scenarios Three decommissioning scenarios were evaluated for the nuclear unit. In all cases, there was some consideration of the decommissioning activities planned at the adjacent Unit 1. However, the scenarios selected are representative of alternatives available to the owner and are defined as follows: 1. Delayed DECON: One of the decommissioning alternatives for Unit 1 is to defer decommissioning until the spent fuel has been removed from the site.[8 I This scenario assumes that the decontamination and dismantling activities at TMI-2 are synchronized with the adjacent unit such that the licenses for both units are terminated concurrently.
- 2. Custodial SAFSTOR: In the second scenario, TMI-1 is placed into long-term storage. TMI-2 remains in storage until such time that decommissioning activities can be coordinated with Unit 1. As with the first scenario, termination of the licenses is coordinated.
- 3. Hardened SAFSTOR: This scenario assumes that Unit 1 is promptly decommissioned when it ceases operations in 2034. In coordination with the Unit 1 activities, the TMI-2 reactor building is reconfigured for long-term, passive storage. Site structures and facilities, with the exception of the reactor building, are decontaminated and dismantled.
The reactor building and its contents are secured and the site is reconfigured for monitored surveillance.
Decontamination and final dismantling of the reactor building is deferred for approximately 100 years (from Unit 1 shutdown).
The scenarios assume that Exelon Generation will be successful in extending the operating license at the adjacent Unit 1 to 2034.[91 The scenarios are also based upon the premise that decommissioning work at Unit 2 would not begin prior to final shutdown of Unit 1 in 2034, consistent with the agreement between Exelon and FirstEnergy.
Methodology The methodology used to develop the estimates described within this document follows the basic approach originally presented in the cost estimating guidelines
[10] developed by the Atomic Industrial Forum (now Nuclear Energy Institute).
This reference describes a unit factor method for determining decommissioning activity costs. The 8 Timelines for the Unit 1 decommissioning scenarios are included in Section 4 of this report.9 Application for TMI-1 license renewal received by the NRC on January 8, 2008 10 T.S. LaGuardia et al., "Guidelines for Producing Commercial Nuclear Power Plant Decommissioning Cost Estimates," AIF/NESP-036, May 1986.TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Page x of xvi unit factors used in this analysis incorporate site-specific costs and the latest available information on worker productivity in decommissioning.
An activity duration critical path is used to determine the total decommissioning program schedule.
The schedule is relied upon in calculating the carrying costs, which include program management, administration, field engineering, equipment rental, and support services such as quality control and security.
This systematic approach for assembling decommissioning estimates ensures a high degree of confidence in the reliability of the resulting cost estimate.Contingency Consistent with cost estimating practice, contingencies are applied to the decontamination and dismantling costs developed as "specific provision for unforeseeable elements of cost within the defined project scope, particularly important where previous experience relating estimates and actual costs has shown that unforeseeable events which will increase costs are likely to occur." 1 1 1 1 The cost elements in the estimates are based on ideal conditions; therefore, the types of unforeseeable events that are almost certain to occur in decommissioning, based on industry experience, are addressed through a percentage contingency applied on a line-item basis. This contingency factor is a nearly universal element in all large-scale construction and demolition projects.
It should be noted that contingency, as used in this analysis, does not account for price escalation and inflation in the cost of decommissioning over the time intervals identified for each scenario.The use and role of contingency within decommissioning estimates is not a safety factor issue. Safety factors provide additional security and address situations that may never occur. Contingency funds, by contrast, are expected to be fully expended throughout the program. Inclusion of contingency is necessary to provide assurance that sufficient funding will be available to accomplish the intended tasks.Low-Level Radioactive Waste Disposal The contaminated and activated material generated in the decontamination and dismantling of a commercial nuclear reactor is classified as low-level (radioactive) waste, although not all of the waste is suitable for "shallow-land" disposal.
With the passage of the "Low-Level Radioactive Waste Policy Act" in 1980,[121 and its Amendments of 1985, [13] the states became ultimately responsible for the disposition of low-level radioactive waste generated within their own borders.Project and Cost Engineers' Handbook, Second Edition, American Association of Cost Engineers, Marcel Dekker, Inc., New York, New York, p. 239.12 "Low-Level Radioactive Waste Policy Act of 1980," Public Law 96-573, 1980.13 "Low-Level Radioactive Waste Policy Amendments Act of 1985," Public Law 99-240, 1986.TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Page xi of xvi Until recently, there were two facilities available to FirstEnergy for the disposal of low-level radioactive waste generated by TMI-2. As of July 1, 2008, however, the facility in Barnwell, South Carolina was closed to generators outside the Atlantic Compact (comprised of the states of Connecticut, New Jersey and South Carolina).
This leaves the facility in Clive, Utah, operated by EnergySolutions, as the only available destination for low-level radioactive waste requiring controlled disposal.EnergySolutions does not have a license to dispose of the more highly radioactive waste (Class B and C as defined by 10 CFR §61) generated in the decontamination and dismantling of the reactor vessel. In the interim (at least until new waste disposal options become available) and for purposes of this analysis, waste disposal costs for this material are based upon the last available Non-Atlantic Compact tariff for disposal at the Barnwell site.Waste exceeding Class C limits (limited to material closest to the reactor core, or material contaminated with spent fuel debris from the March 1979 accident) is generally not suitable for shallow-land disposal.
This material is packaged in the same multipurpose canisters used for spent fuel storage/transport and designated for geologic disposal.A significant portion of the metallic waste generated during decommissioning may only be potentially contaminated by radioactive materials.
This waste can be surveyed on site or shipped off site to licensed facilities for further analysis, for processing and/or for conditioning/recovery.
Reduction in the volume of low-level radioactive waste requiring disposal in a licensed low-level radioactive waste disposal facility can be accomplished through a variety of methods, including analyses and surveys or decontamination to eliminate the portion of waste that does not require disposal as radioactive waste, compaction, incineration or metal melt. The estimates reflect the savings from waste recovery/volume reduction.
Fuel-Bearing Waste Management There will be some wastes generated in the decommissioning of TMI-2 that are not suitable for shallow land burial and therefore cannot be shipped for disposal to EnergySolutions.
This material, primarily associated with systems and structures contaminated with fuel debris, requires greater isolation from the environment.
For estimating purposes, a geologic waste repository, or some interim storage facility, is assumed to be available for the disposal of this material.TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Page xii of xvi Congress passed the "Nuclear Waste Policy Act"[1 4 1 (NWPA) in 1982, assigning the federal government's long-standing responsibility for disposal of the spent nuclear fuel created by the commercial nuclear generating plants to the DOE. The NWPA provided that DOE would enter into contracts with utilities in which DOE would promise to take the utilities' spent fuel and high-level radioactive waste and utilities would pay the cost of the disposition services for that material.
The NWPA, along with the individual contracts with the utilities, specified that the DOE was to begin accepting spent fuel by January 31, 1998.Since the original legislation, the DOE has announced several delays in the program schedule.
By January 1998, the DOE had failed to accept any spent fuel or high level waste, as required by the NWPA and utility contracts.
Delays continue and, as a result, generators have initiated legal action against the DOE in an attempt to obtain compensation for DOE's breach of contract.Operation of DOE's yet-to-be constructed repository is contingent upon the review and approval of the facility's license application by the NRC and the successful resolution of pending litigation.
The DOE submitted its license application to the NRC on June 3, 2008, seeking authorization to construct the repository at Yucca Mountain, Nevada.Assuming a timely review and adequate funding, the DOE expects that receipt of fuel could begin as early as 2020.[15]The estimates for TMI-2 assume the timely removal of waste designated for geologic disposal, without the need for on site interim storage (once containerized).
Site Restoration The efficient removal of the contaminated materials at the site may result in damage to many of the site structures.
Blasting, coring, drilling, and the other decontamination activities will substantially damage power block structures, potentially weakening the footings and structural supports.
Prompt demolition once the license is terminated is clearly the most appropriate and cost-effective option. It is unreasonable to anticipate that these structures would be repaired and preserved after the radiological contamination is removed. The cost to dismantle site structures with a work force already mobilized is more efficient and less costly than if the process were deferred.
Experience at shutdown generating stations has shown that plant facilities quickly degrade without maintenance, adding additional expense and creating potential hazards to the public and the demolition work force.

Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 1, Page I of 12 1. INTRODUCTION This report presents estimates of the cost to decommission the Three Mile Island Unit 2 nuclear unit (TMI-2) for the scenarios described in Section 2. This analysis relies upon site-specific, technical information, originally developed in an evaluation for the GPU Nuclear Corporation in 1995-96 [1]*, and first updated in 2003 for FirstEnergy Corporation
[2]. The analysis is designed to provide the FirstEnergy Corporation with sufficient information to assess its financial obligations, as they pertain to the eventual decommissioning of the nuclear unit. It is not a detailed engineering document, but a financial analysis prepared in advance of the detailed engineering that will be required to carry out the decommissioning.
1.1 OBJECTIVES
OF STUDY The objective of this study was to prepare estimates of the cost, schedule, and waste volumes generated to decommission TMI-2, including all areas affected by the March 1979 accident.Three decommissioning scenarios were evaluated for TMI-2. In each scenario decommissioning activities are coordinated with the adjacent operating unit (TMI-1 or Unit 1). The scenarios assume that Exelon Generation will be successful in extending the Unit 1 operating license to 2034. The three scenarios are also based upon the premise that decommissioning work at Unit 2 would not begin prior to final shutdown of Unit 1 in 2034, consistent with the agreement between Exelon and FirstEnergy.
The base scenario assumes that TMI-1 is decommissioned following the removal of spent fuel from the site. The decommissioning program for TMI-2 runs concurrently with the TMI-1 decommissioning effort and concludes with the termination of both licenses.
This scenario is subsequently referred to as"Delayed DECON." The second scenario assumes that TMI-1 is placed into safe-storage with decommissioning deferred 60 years. TMI-2 remains in storage with decommissioning deferred until it can be sequenced with TMI-1. This scenario is subsequently referred to as "Custodial SAFSTOR." The final scenario assumes that TMI-1 is promptly decommissioned upon the scheduled cessation of operations in 2034. The reactor building at TMI-2 is modified for long-term, passive storage with all other Unit 2 facilities

Remediation of the reactor building is deferred for a period of approximately 100 years at which time it is decontaminated and dismantled.
This scenario is subsequently referred to as"Hardened SAFSTOR." 1.2 SITE DESCRIPTION TMI-2 is located on the northern-most section of Three Mile Island near the east shore of the Susquehanna River in Dauphin County, Pennsylvania.
The station is comprised of two pressurized water reactors.
This study specifically addresses the decommissioning requirements for Unit 2, although the timing of each scenario is dependent upon the associated activities at the adjacent unit.The nuclear steam supply system (NSSS) consists of a pressurized water reactor rated at a core thermal power level of 2772 MWth with a corresponding turbine-generator gross output of 959 MWe. The NSSS consists of the reactor with two independent primary coolant loops, each containing two reactor coolant pumps and a steam generator.
An electrically heated pressurizer and connecting piping complete the system. The system is housed within a steel-lined, post-tensioned concrete structure (reactor building) in the shape of a right, vertical cylinder with a hemispherical dome and a flat, reinforced concrete basemat. A welded steel liner plate, anchored to the inside face of the reactor building, serves as a leak-tight membrane.Heat produced in the reactor was converted to electrical energy by the turbine generator system. This system converted the thermal energy of the steam into mechanical shaft power and then into electrical energy. The turbine-generator is a tandem-compound design, consisting of one double-flow, high pressure turbine and two double-flow, low-pressure turbines driving a directly coupled generator at 1800 rpm. The turbine operated in a closed feedwater cycle where steam was condensed, feedwater heated, and ultimately returned to the steam generators.
Heat rejected in the main condensers was removed by the condenser circulating and river water systems.The condenser circulating water was cooled in two hyperbolic natural draft cooling towers located to the east of the station. The towers provided the heat sink required for removal of waste heat in the power plant's thermal cycle.Cooling tower blowdown was discharged to the Susquehanna River.TMI-2's operating license was issued on February 8, 1978, with commercial operation declared on December 30, 1978. On March 28, 1979, the unit experienced an accident initiated by interruption of secondary feedwater flow.TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 1, Page 3 of 12 The steam generator boiled dry, resulting in the reduction of primary-to-secondary heat exchange.
This caused an increase in the primary coolant temperature, creating a surge into the pressurizer, and an increase in system pressure.
The pilot operated relief valve (PORV) opened to relieve the pressure, but failed to close when the pressure decreased.
The reactor coolant pumps were turned off and a core heat-up began as the water level decreased to uncover the top of the core. The melting temperature of the zircaloy fuel cladding was exceeded, resulting in relocation of the molten zircaloy and some liquefied fuel to the lower core regions, solidifying near the coolant interface.
Based on the end-state core and core support assembly configuration and supporting analysis of the degraded core heat-up, it is believed that as the crust failed, molten core material migrated to the lower internals.
The majority of the molten material flowed down through the region of the southeastern assemblies and into the core bypass region. A portion of the molten core material flowed around the bypass region and migrated down into the lower internals and lower head region. Limited damage to the core support assembly occurred as the core material flowed to the lower plenum. It is estimated that about 17 -20 tons of material relocated to the lower internals and lower head region. Several in-core instrument guide tubes were melted but overall vessel integrity was maintained throughout the accident.As a result of this accident, small quantities of core debris and fission products were transported through the RCS and the reactor building.
as a result of the coolant flow through the PORV and the makeup and purification system (MU&P) during the accident.
In addition, a small quantity of core debris was transported to the auxiliary and fuel handling buildings (AFHB) via the MU&P. Further spread of the debris also occurred as part of the post-accident water processing cleanup activities.
GPU Nuclear conducted a substantial program to defuel the reactor vessel and decontaminate the facility.
As a result, TMI-2 has been placed in a safe, inherently stable condition suitable for long-term management, and any threat to the public health and safety has been eliminated.
Fuel and core material removed in the defueling has been shipped off site. The current long-term management condition is termed Post-Defueling Monitored Storage (PDMS).The costs for maintaining TMI-2 in this state until the onset of Unit 2 decommissioning is accrued in a separate nuclear liability account by FirstEnergy and therefore is not included in the cost estimates in this analysis.Substantial contaminated areas still exist under the PDMS, as well as trace quantities of spent nuclear fuel (SNF). Several cubicles in the auxiliary and fuel handling buildings remain locked, and the basement of the reactor building has been uninhabitable since the accident.
The quantity of fuel TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 1, Page 4 of 12 remaining at TMI-2 is a small fraction of the initial fuel load; approximately 99% was successfully removed in the defueling.
Additionally large quantities of radioactive fission products were released into various systems and structures.
Most of this radioactivity was removed as part of the waste processing activities during the TMI-2 Clean-up Program which concluded with entry into Post-Defueling Monitored Storage in December 1993.Significant quantities of radioactive fission products were removed from the reactor coolant system in preparation for the PDMS. However, the remaining 1% of the fuel and the remaining fission products pose unique problems in completing the decommissioning of TMI-2. A summary of the quantity and suspected location of the remaining fuel debris is provided in Tables 1.1 through 1.3.1.3 REGULATORY GUIDANCE The Nuclear Regulatory Commission (NRC or Commission) provided initial decommissioning requirements in its rule "General Requirements for Decommissioning Nuclear Facilities," issued in June 1988 [3]. This rule set forth financial criteria for decommissioning licensed nuclear power facilities.
The regulation addressed decommissioning planning needs, timing, funding methods, and environmental review requirements.
The intent of the rule was to ensure that decommissioning would be accomplished in a safe and timely manner and that adequate funds would be available for this purpose.Subsequent to the rule, the NRC issued Regulatory Guide 1.159, "Assuring the Availability of Funds for Decommissioning Nuclear Reactors,"[41 which provided additional guidance to the licensees of nuclear facilities on the-financial methods acceptable to the NRC staff for complying with the requirements of the rule. The regulatory guide addressed the funding requirements and provided 'guidance on the content and form of the financial assurance mechanisms indicated in the rule.The rule defined three decommissioning alternatives as being acceptable to the NRC: DECON, SAFSTOR, and ENTOMB. The DECON alternative, the option evaluated for this analysis, assumes that any contaminated or activated portion of the plant's systems, structures, and facilities are removed or decontaminated to levels that permit the site to be released for unrestricted use shortly after the cessation of plant operations.
The rule also placed limits on the time allowed to complete the decommissioning process. For SAFSTOR, the process is restricted in overall duration to 60 years, unless it can be shown that a longer duration is necessary to protect public health and safety. The guidelines for ENTOMB are similar, providing the NRC with both sufficient leverage and flexibility to ensure that these deferred options are only used in situations where it is reasonable and consistent with the definition of TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 1, Page 5 of 12 decommissioning.
At the conclusion of a 60-year dormancy period (or longer for ENTOMB if the NRC approves such a case), the site would still require significant remediation to meet the. unrestricted release limits for license termination.
To use a decommissioning scenario in which the license has not been terminated within 60 years of the final shutdown date, FirstEnergy will need Commission approval pursuant to 10 CFR 50.82(a)(3) for completion of decommissioning beyond 60 years.The ENTOMB alternative has not been viewed as a viable option for power reactors due to the significant time required to isolate the long-lived radionuclides for decay to permissible levels. However, with recent rulemaking permitting the controlled release of a site, the NRC has re-evaluated this alternative.[
5 I The resulting feasibility study, based upon an assessment by Pacific Northwest National Laboratory, concluded that the method did have conditional merit for some, if not most, reactors.[
6 I However, the staff also found that additional rulemaking would be needed before this option could be treated as a generic alternative.
Rulemaking has been deferred pending the completion of additional research studies, e.g., on engineered barriers.However, this study assumes that the ENTOMB alternative is a viable option for TMI-2 and that a storage period of 100 years would be acceptable.
The NRC published revisions to the general requirements for decommissioning nuclear power plants in 1996.171 When the regulations were adopted in 1988, it was assumed that the majority of licensees would decommission at the end of the facility's licensed life. Since that time, several licensees permanently and prematurely ceased operations.
Exemptions from certain operating requirements were required once the reactor was defueled to facilitate the decommissioning.
Each case was handled individually, without clearly defined generic requirements.
The NRC amended the decommissioning regulations in 1996 to clarify ambiguities and codify procedures and terminology as a means of enhancing efficiency and uniformity in the decommissioning process. The new amendments allow for greater public participation and better define the transition process from operations to decommissioning.
1.3.1 Nuclear
Waste Policy Act Congress passed the Nuclear Waste Policy Act[8] (NWPA) in 1982, assigning the responsibility for disposal of the spent nuclear fuel created by the commercial nuclear generating plants to the U.S. Department of Energy (DOE). Two permanent disposal facilities and an interim storage facility were envisioned.
To recover the cost, the legislation created a Nuclear Waste Fund through which money is collected from the sale of electricity generated by the power plants. The NWPA, along with the TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 1, Page 6 of 12 individual disposal contracts with the utilities, specified that the DOE was to begin accepting spent fuel by January 31, 1998.Since the original legislation, the DOE has announced several delays in the program schedule.
By January 1998, the DOE had failed to accept any spent fuel or high level waste, as required by the NWPA and utility contracts.
Delays continue and, as a result, generators have initiated legal action against the DOE in an attempt to obtain compensation for DOE's breach of contract.Operation of DOE's yet-to-be constructed repository is contingent upon the review and approval of the facility's license application by the NRC and the successful resolution of pending litigation.
The DOE submitted its license application to the NRC on June 3, 2008, seeking authorization to construct the repository at Yucca Mountain, Nevada. Assuming a timely review and adequate funding, the DOE expects that receipt of fuel could begin as early as 2020.[91 The estimates for TMI-2 assume the timely removal of waste designated for geologic disposal, without the need for interim on site storage (once containerized).
1.3.2 Low-Level Radioactive Waste Acts The contaminated and activated material generated in the decontamination and dismantling of a commercial nuclear reactor is classified as low-level (radioactive) waste, although not all of the material is suitable for "shallow-land" disposal.
Congress passed the"Low-Level Radioactive Waste Policy Act" in 1980,[110 declaring the states as being ultimately responsible for the disposition of low-level radioactive waste generated within their own borders. The federal law encouraged the formation of regional groups or compacts to implement this objective safely, efficiently, and economically, and set a target date of 1986 for implementation.
After little progress, the "Low-Level Radioactive Waste Policy Amendments Act of 1985,"[11]
extended the implementation schedule, with specific milestones and stiff sanctions for non-compliance.
However, to date, no new compact facilities have been successfully sited, licensed, and constructed.
Until recently, there were two facilities available to FirstEnergy for the disposal of low-level radioactive waste generated by TMI-2. As of July 1, 2008, however, the facility in Barnwell, South Carolina was closed to generators outside the Atlantic Compact (comprised of the states of TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 1, Page 7 of 12 Connecticut, New Jersey and South Carolina).
This leaves the facility in Clive, Utah, operated by EnergySolutions, as the only available destination for low-level radioactive waste requiring controlled disposal.EnergySolutions does not have a license to dispose of the more highly radioactive waste (Class B and C as defined by 10 CFR §61) generated in the dismantling of the reactor vessel. In the interim (at least until new waste disposal options become available) and for purposes of this analysis, waste disposal costs for this material are based upon the last available Non-Atlantic Compact tariff for disposal at the Barnwell site.Material exceeding Class C limits (limited to material closest to the reactor core, or material contaminated with spent fuel debris) is generally not suitable for shallow-land disposal.
This material is packaged in the same multipurpose canisters used for spent fuel storage/transport and designated for geologic disposal.A significant portion of the metallic waste generated during decommissioning may only be potentially contaminated by radioactive materials.
This waste can be surveyed on site or shipped off site to licensed facilities for further analysis, for processing and/or for conditioning/recovery.
Reduction in the volume of low-level radioactive waste requiring disposal in a licensed low-level radioactive waste disposal facility can be accomplished through a variety of methods, including analyses and surveys or decontamination to eliminate the portion of waste that does not require disposal as radioactive waste, compaction, incineration or metal melt. The estimates reflect the savings from waste recovery/volume reduction.
1.3.3 Radiological
Criteria for License Termination In 1997, the NRC published Subpart E, "Radiological Criteria for License Termination,"[1 2] amending 10 CFR §20. This subpart provides radiological criteria for releasing a facility for unrestricted use. The regulation states that the site can be released for unrestricted use if radioactivity levels are such that the average member of a critical group would not receive a Total Effective Dose Equivalent (TEDE) in excess of 25 millirem per year, and provided that residual radioactivity has been reduced to levels that are As Low As Reasonably Achievable (ALARA).The decommissioning estimates for TMI-2 assume that the site will be remediated to a residual level consistent with the NRC-prescribed level." TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 1, Page 8 of 12 It should be noted that the NRC and the Environmental Protection Agency (EPA) differ on the amount of residual radioactivity considered acceptable in site remediation.
The EPA has two limits that apply to radioactive materials.
An EPA limit of 15 millirem per year is derived from criteria established by the Comprehensive.
Environmental Response, Compensation, and Liability Act (CERCLA or Superfund).[
1 3 1 An additional limit of 4 millirem per year, as defined in 40 CFR §141.16, is applied to drinking water.[1 4]On October 9, 2002, the NRC signed an agreement with the EPA on the radiological decommissioning and decontamination of NRC-licensed sites. The Memorandum of Understanding (MOU) [151 provides that EPA will defer exercise of authority under CERCLA for the majority of facilities decommissioned under NRC authority.
The MOU also includes provisions for NRC and EPA consultation for certain sites when, at the time of license termination, (1) groundwater contamination exceeds EPA-permitted levels; (2) NRC contemplates restricted release of the site; and/or (3) residual radioactive soil concentrations exceed levels defined in the MOU.The MOU does not impose any new requirements on NRC licensees and should reduce the involvement of the EPA with NRC licensees who are decommissioning.
Most sites are expected to meet the NRC criteria for unrestricted use, and the NRC believes that only a few sites will have groundwater or soil contamination in excess of the levels specified in the MOU that trigger consultation with the EPA. However, if there are other hazardous materials on the site, the EPA may be involved inthe cleanup. As such, the possibility of dual regulation remains for certain licensees.
The present study does not include any costs for this occurrence.

Although the alternatives differ with respect to technique, process, cost, and schedule, they attain the same result: the ultimate release of the site for unrestricted use.Three decommissioning scenarios were evaluated for the nuclear unit. The scenarios assume that Exelon Generation will be successful in extending the operating license for Unit 1 to 2034. The scenarios are defined as follows: 1. Delayed DECON: One of the decommissioning alternatives for Unit 1 is to defer decommissioning until the spent fuel has been removed from the site.This scenario assumes that the decontamination and dismantling activities at TMI-2 are synchronized with the adjacent unit such that the licenses for both units are terminated concurrently.
- 2. Custodial SAFSTOR: In the second scenario, TMI-1 is placed into long-term storage. TMI-2 remains in storage until such time that decommissioning activities can be coordinated with Unit 1. As with the first scenario, termination of the licenses is coordinated.
- 3. Hardened SAFSTOR: This scenario assumes that Unit 1 is promptly decommissioned when it ceases operations in 2034. In coordination with the Unit 1 activities, the TMI-2 reactor building is reconfigured for long-term, passive storage. Site structures and facilities, with the exception of the reactor building, are decontaminated and dismantled.
The reactor building and its contents are secured and the site is reconfigured for monitored surveillance.
Decontamination and final dismantling of the reactor building is deferred for approximately 100 years (from Unit 1 shutdown).
For each of the three scenarios described above, dormancy costs are accrued from the cessation of TMI-1 operations.
This means that the current PDMS costs are not included within the reported decommissioning costs.The following sections describe the basic activities associated with each alternative.
The first two scenarios are essentially identical.
The technical assumptions are unchanged with the only difference in the second scenario being the delay in start of decommissioning expenditures and the additional storage cost during the delay period. The third scenario reduces the controlled area to the reactor building, similar to that envisioned for an entombment alternative, without the extensive engineered barriers.TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 2, Page 2 of 10 Although detailed procedures for each activity identified are not provided, and the actual sequence of work may vary, the activity descriptions provide a basis not only for estimating but also for the expected scope of work, i.e., engineering and planning at the time of decommissioning.
The conceptual approach that the NRC has described in its regulations divides decommissioning into three phases. The initial phase addresses the transition of reactor operations (i.e., power production) to facility de-activation and closure. The second phase encompasses activities during the storage period or during major decommissioning activities, or a combination of the two. The third phase pertains to the activities involved in license termination.
The decommissioning estimates developed for TMI-2 are also divided into phases or periods; however, demarcation of the phases is based upon major milestones within the project or significant changes in the projected expenditures.
2.1 DELAYED
DECON The TMI-2 plant has effectively been placed in a SAFSTOR condition since the completion of the spent fuel removal activities and beginning of the PDMS.However, the engineering and planning requirements for completing the decommissioning process are similar to those for a DECON alternative.
Unit 2 decommissioning operations are integrated with Unit l's spent fuel transfer campaign such that the licenses are terminated concurrently.
2.1.1 Period
2 -Dormancy The dormancy costs included in this estimate are limited to monitoring activities only. Although TMI-2 has been in a dormant condition since entry into Post-Defueling Monitored Storage in December 1993, this estimate only includes those costs for maintaining the unit subsequent to the currently scheduled cessation of operations at Unit 1 in April of 2034 (i.e., current costs are not included).
Security during the dormancy period is conducted primarily to prevent unauthorized entry and to protect the public from the consequences of its own actions. Security is provided by fences, sensors, alarms, and other surveillance equipment.
Fire and radiation alarms are also monitored.
TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 2, Page 3 of 10 2.1'.2 Period 3 -Preparations Preparations include the planning for the removal of the remaining fuel-bearing components, decontamination of the structures and the dismantling of the remaining equipment and facilities.
Typically, the process is described within a Post-Shutdown Decommissioning Activities Report (PSDAR) or a Decommissioning Plan (DP). Although the exact format and content of the decommissioning planning document has not been identified, as a minimum Technical Specification 3.2.1.1 requires NRC approval prior to removal of greater than 42 kilograms of fuel from the reactor vessel. Thus in addition to the planning document, changes may be required to the existing technical specifications prior to the start of major decommissioning activities.
Engineering and Planning The decommissioning program outlined in the PSDAR or DP will be designed to accomplish the required tasks within the ALARA guidelines (as defined in 10 CFR §20) for protection of personnel from exposure to radiation hazards. It will also address the continued protection of the health and safety of the public and the environment during the dismantling activity.
Consequently, with the development of the decommissioning plan, activity specifications, cost-benefit and safety analyses, and work packages and procedures, would be assembled to support the proposed decontamination and dismantling activities.
The estimate assumes that FirstEnergy will provide project oversight.
However, the majority of the professional, managerial, technical and administrative support staff will be provided by a decommissioning operations contractor (DOC).Site Preparations In preparation for active decommissioning, the following activities are initiated:
Characterization of the site and surrounding environs.
This includes radiation surveys of the reactor building including:
the basement and elevator block wall area, areas surrounding major components (including the reactor vessel and its internals, steam generators), internal piping, and primary shield cores. Surveys of the auxiliary and fuel handling building with emphasis on areas with known and potential alpha contamination and know fission TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 2, Page 4 of 10 products.
Surveys and sample analysis will also be performed on exterior buildings, land areas surrounding the facility, subsurface soil and groundwater.
- Specification of transport and disposal requirements for highly radioactive waste and/or hazardous waste, including shielding and waste stabilization.
- Development of procedures for occupational exposure control, control and release of liquid and gaseous effluent, processing of radwaste (including dry-active waste, resins, filter media, metallic and non-metallic components generated in decommissioning), site security and emergency programs, and industrial safety.2.1.3 Period 4 -Decommissioning Operations This period includes the physical decommissioning activities associated with the removal and disposal of contaminated and highly radioactive components and structures, including the successful termination of the license. Significant decommissioning activities in this phase include:* Construction of temporary facilities and/or modification of existing facilities to support dismantling activities.
This may include a centralized processing area to facilitate equipment removal and component preparations for off-site disposal." Refurbishment of the containment air control envelope building located outside the reactor building equipment hatch. A prefabricated metal containment building located on the 305' level of the reactor building will be required for the handling of highly contaminated material being removed from the basement or the operating deck elevations." Modification of the containment structure to facilitate handling of large equipment.
This will include an evaluation to determine whether a temporary crane should be installed or whether the existing polar crane should be refurbished (the reactor vessel head will be the heaviest lift under the current removal scenario with the in-situ segmentation of the reactor vessel and steam generators)." Reconfiguration and modification of site structures and facilities as needed to support decommissioning operations.
This may include the upgrading of roads and rail facilities (on- and off-site) to facilitate hauling and transport.
Modifications may also be required to the refueling area of the building to support the segmentation of the reactor vessel internals and component extraction.

Certain areas in the auxiliary and spent fuel handling buildings contain very high contamination and radiation levels and will require additional resource and increased radiological protection to complete the decontamination.
Radiation and contamination controls will be utilized until residual levels indicate that the structures and equipment can be released for unrestricted access and conventional demolition.
This activity may necessitate the dismantling and disposition of most of the systems and components (both clean and contaminated) located within these buildings.
This activity facilitates surface decontamination and subsequent verification surveys required prior to obtaining release for demolition.
Material that is designated as scrap or general disposal (survey and release) is transferred to a designed waste processing vendor for a confirmatory survey and, if permitted, released for unrestricted disposition.
Contaminated material is characterized and segregated for additional off-site processing (disassembly, chemical cleaning, volume reduction, and waste treatment), and/or packaged for controlled disposal at a low-level radioactive waste disposal facility.Incorporated into the LTP is the Final Survey Plan. This plan identifies the radiological surveys to be performed once the decontamination activities are completed and is developed using the guidance provided in the "Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM)."[171 This document incorporates the statistical approaches to survey design and data interpretation used by the EPA. It also identifies state-of-the-art, commercially available instrumentation and procedures for conducting radiological surveys. Use of this guidance ensures that the surveys are conducted in a manner that provides a high degree of confidence that applicable NRC criteria are satisfied.
Once the survey is complete, the results are provided to the NRC in a format that can be verified.
The NRC then reviews and evaluates the information, performs an independent confirmation of radiological site conditions, and makes a determination on final termination of the license.The NRC will terminate the license if it determines that site remediation has been performed in accordance with the LTP, and that TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 2, Page 8 of 10 the terminal radiation survey and associated documentation demonstrate that the facility is suitable for release.2.1.4 Period 5 -Site Restoration Following completion of decommissioning operations, site restoration activities will begin. Efficient removal of the contaminated materials and verification that residual radionuclide concentrations are below the NRC limits will result in substantial damage to many of the remaining structures.
Prompt dismantling of remaining site structures is clearly the most appropriate and cost-effective option. It is unreasonable to anticipate that these structures would be repaired and preserved after the radiological contamination is removed. The cost to dismantle site structures with a work force already mobilized on site is more efficient than if the process were deferred.
Site facilities quickly degrade without maintenance, adding additional expense and creating potential hazards to the public as well as to future workers. Abandonment creates a breeding ground for vermin infestation as well as other biological hazards.This cost study presumes that non-essential structures and site facilities are dismantled as a continuation of the decommissioning activity.Foundations and exterior walls are removed to a nominal depth of three feet below grade. The three-foot depth allows for the placement of gravel for drainage, as well as topsoil, so that vegetation can be established for erosion control. Site areas affected by the dismantling activities are restored and the plant area graded as required to prevent ponding and inhibit the refloating of subsurface materials.
Concrete rubble produced by demolition activities is processed to remove rebar and miscellaneous embedments.
The processed material is then used, on site to backfill voids. Excess materials are trucked to an off-site area for disposal as construction debris.2.2 CUSTODIAL SAFSTOR The decontamination and dismantling activities in this scenario are identical to those described in Section 2.1 for Delayed DECON. However, the start of active decommissioning is deferred to coordinate with the timing of the Unit 1 SAFSTOR scenario.
As such, the duration of the dormancy period is significantly longer and the storage costs correspondingly greater.TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 2, Page 9 of 10 While it is expected that radiation dose levels will decrease over the duration of the longer dormancy period, the nature of radionuclides involved and the difficulties in working in plant areas contaminated with these radionuclides will require similar operational and radiological controls to those envisioned for earlier scenario.
As such, there have been no changes incorporated into the costs to perform the field decommissioning activities identified in Section 2.1 for this scenario.2.3 HARDENED SAFSTOR This scenario is similar to what has been generally described as the ENTOMB option. The NRC has defined the ENTOMB option as "the alternative in which radioactive contaminants are encased in a structurally long-lived material, such as concrete; the entombed structure is appropriately maintained and continued surveillance is carried out until the radioactive material decays to a level permitting unrestricted release of the property." As with the SAFSTOR alternative, decommissioning is currently required to be completed within 60 years. However, durations of up to 100 years may be considered where there are demonstrated benefits to the safety and health of the public.This option reduces the long-term radiological footprint on the site by contracting the controlled area to the reactor building.
Contamination outside this area is removed in the early stages of Hardened SAFSTOR decommissioning, concurrent with the decommissioning of Unit 1. Removal activities are performed in a similar fashion to their counterparts in the Delayed DECON scenario.
Upon completion of the process, the reactor building is sealed with appropriate security and monitoring measures installed.
As in the Delayed DECON and Custodial SAFSTOR dormancies, the purpose of the dormancy period is to isolate the contamination on site, and to protect the public from the consequences of their own actions. The difference between the Hardened SAFSTOR dormancy and the other two scenarios is that generally the site is uninhabited; security and radiation monitoring are performed remotely.Following the end of the Hardened SAFSTOR dormancy period, the reactor building and its contents are removed and disposed of in a similar fashion as discussed in the Delayed DECON scenario.
Following the termination of the license and the limited restoration of the affected area, the site is available for unrestricted, alternative use.While it is expected that radiation dose levels will decrease over the dormancy period, the nature of radionuclides involved and the difficulties in working in TLG Services, Inc.

Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 3, Page 1 of 27 3. COST ESTIMATE The cost estimates prepared for decommissioning TMI-2 consider the radiological status, unique conditions of the site, including the NSSS, power generation systems, support services, site buildings, and ancillary facilities.
The basis of the estimates, including the sources of information relied upon, the estimating methodology employed, site-specific considerations, and other pertinent assumptions, is described in this section.3.1 BASIS OF ESTIMATE The estimates rely upon site-specific, technical information originally developed in an evaluation prepared for the GPU Nuclear Corporation in 1995-96, and updated for FirstEnergy in 2003. The information was reviewed for the current analysis and updated as deemed appropriate.
The site-specific considerations and assumptions used in the previous evaluation were also revisited.
Modifications were incorporated where new information was available or experience from ongoing decommissioning programs provided viable alternatives or improved processes.
Some of the technical assumptions that were used are due to the unique nature and characteristics of the plant as a result of the March 1979 accident.Following the accident, TMI-2 was defueled and extensive decontamination activities were performed.
This successfully removed approximately 99% of the original fuel and resulting fuel debris. Removal of the residual 1% was neither cost effective nor warranted due to the high radiation fields in the reactor building and adjoining auxiliary and fuel handling buildings.
The remaining equipment and components containing spent nuclear fuel (SNF) will be removed, sealed and/or encapsulated in preparation for disposal during the decommissioning program.3.2 METHODOLOGY The methodology used to develop the estimates follows the basic approach originally presented in the AIF/NESP-036 study report, "Guidelines for Producing Commercial Nuclear Power Plant Decommissioning Cost Estimates,"[
1 81 and the DOE "Decommissioning Handbook."[
1 9 1 These documents present a unit factor method for estimating decommissioning activity costs, which simplifies the estimating calculations.
Unit factors for concrete removal ($/cubic yard), steel removal ($/ton), and cutting costs ($/inch)were developed using local labor rates. The activity-dependent costs were estimated with the item quantities (cubic yards and tons), developed from TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 3, Page 2 of 27 plant drawings and inventory documents.
Removal rates and material costs for the conventional disposition of components and structures relied upon information available in the industry publication, "Building Construction Cost Data," published by R.S. Means.[2 0]This analysis reflects lessons learned from TLG's involvement in the Shippingport Station Decommissioning Project, completed in 1989, as well as the decommissioning of the Cintichem reactor, hot cells, and associated facilities, completed in 1997. In addition, the planning and engineering for the Pathfinder, Shoreham, Rancho Seco, Trojan, Yankee Rowe, Big Rock Point, Maine Yankee, Humboldt Bay-3, Oyster Creek, Connecticut Yankee, and San Onofre-1 nuclear units have provided additional insight into the process, the regulatory aspects, and the technical challenges of decommissioning commercial nuclear units.The unit factor method provides a demonstrable basis for establishing reliable cost estimates.
The detail provided in the unit factors, including activity duration, labor costs (by craft), and equipment and consumable costs, ensures that essential elements have not been omitted. Appendix A presents the detailed development of a typical unit factor. Appendix B provides the values contained within one set of factors developed for this analysis.Work Difficulty Factors TLG has historically applied work difficulty adjustment factors (WDFs) to account for the inefficiencies in working in a power plant environment and increase the time required to perform the activity.
WDFs were assigned to each unique set of unit factors, commensurate with the inefficiencies associated with working in confined, hazardous environments.
The WDF sets were developed considering the extremely difficult working conditions associated with working in high radiation areas and in areas with high alpha particle contamination.
The same work difficulty factor sets were used for all three scenarios.
This assumption was based upon the relatively high levels of long-lived radioactivity that exists today plus the high levels of alpha contamination.
The factors and their associated range of values were developed in conjunction with the AIF/NESP-036 study. The application of the factors is discussed in more detail in that publication.
Given the radiological status of some areas at TMI-2, the range of the WDF's was increased.
The ranges used for the WDFs are identified in the following table.TLG Services, Inc.

The resulting man-hours, or crew-hours, are used in the development of the decommissioning program schedule, using resource loading and event sequencing considerations.
The scheduling of conventional removal and dismantling activities are based upon productivity information available from the "Building Construction Cost Data" publication.
An activity duration critical path is used to determine the total decommissioning program schedule.
The schedule is relied upon in calculating the carrying costs, which include program management, administration, field engineering, equipment rental, and support services such as quality control and security.
This systematic approach for assembling decommissioning estimates ensures a high degree of confidence in the reliability of the resulting cost estimate.3.3 IMPACT OF DECOMMISSIONING MULTIPLE REACTOR UNITS In estimating the near simultaneous decommissioning of two co-located reactor units there can be opportunities to achieve economies of scale, by sharing costs between units, and coordinating the sequence of work activities.
There will also be schedule constraints, particularly where there are requirements for specialty equipment and staff, or practical limitations on when final status surveys can take place. A summary of the principal impacts are listed below.Consistent with the agreement between FirstEnergy and Exelon regarding the timing of decommissioning activities at TMI-2, it is TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 3, Page 4 of 27 assumed that decommissioning at TMI-2 will begin in 2034. Under the terms of this agreement, decommissioning activities at Unit 2 cannot begin while Unit 1 is still in commercial operation.
The decommissioning scenarios used in this analysis are structured to integrate to the extent possible with a Unit 1 decommissioning scenario.* Since the security program for the site is likely to be an integrated approach, the security guard force is assumed to be shared to varying degrees between the units, depending upon the level of activities at each unit. This reduces the security costs for the decommissioning estimates for both units on site.* The final radiological survey schedule is also affected by a two-unit decommissioning schedule.
It would be considered impractical to try to complete the final status survey of Unit 1, while Unit 2 still has ongoing radiological remediation work and waste handling in process. As such, this analysis has structured the decommissioning scenarios for Unit 2 to coordinate the final status survey for the station.3.4 FINANCIAL COMPONENTS OF THE COST MODEL TLG's proprietary decommissioning cost model, DECCER, produces a number of distinct cost elements.
These direct expenditures, however, do not comprise the total cost to accomplish the project goal, i.e., license termination and site restoration.
Inherent in any cost estimate that does not rely on historical data is the inability to specify the precise source of costs imposed by factors such as tool breakage, accidents, illnesses, weather delays, and labor stoppages.
In the DECCER cost model, contingency fulfills this role. Contingency is added to each line item to account for costs that are difficult or impossible to develop analytically.
Such costs are historically inevitable over the duration of a job of this magnitude; therefore, this cost analysis includes funds to cover these types of expenses.3.4.1 Contingency The activity-and period-dependent costs are combined to develop the total decommissioning cost. A contingency is then applied on a line-item basis, using one or more of the contingency types listed in the AIF/NESP-036 study. "Contingencies" are defined in the American Association of Cost Engineers "Project and Cost Engineers' Handbook"[
2 1 1 as "specific provision for unforeseeable elements of cost within the defined project scope; particularly important where previous TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 3, Page 5 of 27 experience relating estimates and actual costs has shown that unforeseeable events which will increase costs are likely to occur." The cost elements in this analysis are based upon ideal conditions and maximum efficiency; therefore, consistent with industry practice, a contingency factor has been applied. In the AIF/NESP-036 study, the types of unforeseeable events that are likely to occur in decommissioning are discussed and guidelines are provided for percentage contingency in each category.
It should be noted that contingency, as used in this analysis, does not account for price escalation and inflation in the cost of decommissioning over the time intervals identified for each scenario.The use and role of contingency within decommissioning estimates is not a "safety factor issue." Safety factors provide additional security and address situations that may never occur. Contingency funds are expected to be fully expended throughout the program. They also provide assurance that sufficient funding is available to accomplish the intended tasks. An estimate without contingency, or from which contingency has been removed, can disrupt the orderly progression of events and jeopardize a successful conclusion to the decommissioning process.For example, the most technologically challenging task in decommissioning a commercial nuclear station is the disposition of the reactor vessel and internal components, highly radioactive following the accident.
The disposition of these components forms the basis of the critical path (schedule) for decommissioning operations.
Cost and schedule are interdependent, and any deviation in schedule has a significant impact on cost for performing a specific activity.Disposition of the reactor vessel internals involves the underwater cutting of complex components that are highly radioactive.
Costs are based upon optimum segmentation, handling, and packaging scenarios.
The schedule is primarily dependent upon the turnaround time for the heavily shielded shipping casks, including preparation, loading, and decontamination of the containers for transport.
The number of casks required is a function of the pieces generated in the segmentation activity, a value calculated on optimum performance of the tooling employed in cutting the various subassemblies.
The expected optimization, however, may not be achieved, resulting in delays and additional program costs. For this reason, contingency must be included to mitigate the consequences of the expected inefficiencies inherent in this complex activity, along with related concerns associated with the TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 3, Page 6 of 27 operation of highly specialized tooling, field conditions, and water clarity.Contingency funds are an integral part of the total cost to complete the decommissioning process. Exclusion of this component puts at risk a successful completion of the intended tasks and, potentially, subsequent related activities.
For this study, TLG examined the major activity-related problems (decontamination, segmentation, equipment handling, packaging, transport, and waste disposal) that necessitate a contingency.
Individual activity contingencies ranged from 10% to 75%, depending on the degree of difficulty judged to be appropriate from TLG's actual decommissioning experience.
The contingency values used in this study are as follows: Decontamination 50%Contaminated Component Removal 25%Contaminated Component Packaging 10%Contaminated Component Transport 15%Low-Level Radioactive Waste Disposal 25%Reactor Segmentation 75%NSSS Component Removal 25%Reactor Waste Packaging 25%Reactor Waste Transport 25%Reactor Vessel Component Disposal 50%GTCC Disposal 15%Non-Radioactive Component Removal 15%Heavy Equipment and Tooling 15%Supplies 25%Engineering 15%Energy 15%Characterization and Termination Surveys 30%Construction 15%Taxes and Fees 10%Insurance 10%Staffing 15%The contingency values are applied to the appropriate components of the estimates on a line item basis. A composite value is then reported at the end of each estimate.
For example, the composite contingency value reported for the Delayed DECON alternative is 19.5%. Values for the TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 3, Page 7 of 27 other alternatives are delineated within the detailed cost tables in Appendix D and E.3.4.2 Financial Risk In addition to the routine uncertainties addressed by contingency, another cost element that is sometimes necessary to consider when bounding decommissioning costs relates to uncertainty, or risk.Examples can include changes in work scope, pricing, job performance, and other variations that could conceivably, but not necessarily, occur.Consideration is sometimes necessary to generate a level of confidence in the estimate, within a range of probabilities.
TLG considers these types of costs under the broad term "financial risk." Included within the category of financial risk are:* Delays in approval of the decommissioning plan due to intervention, public participation in local community meetings, legal challenges, and national and local hearings.* Changes in the project work scope from the baseline estimate, involving the discovery of unexpected levels of contaminants, contamination in places not previously expected, contaminated soil previously undiscovered (either radioactive or hazardous material contamination), variations in plant inventory or configuration not indicated by the as-built drawings." Regulatory changes, e.g., affecting worker health and safety, site release criteria, waste transportation, and disposal.* Policy decisions altering national commitments, e.g., in the ability to accommodate certain waste forms for disposition or in the timetable for such, e.g., the start and rate of acceptance of spent fuel by the DOE." Pricing changes for basic inputs, such as labor, energy, materials, and burial. Some of these inputs may vary slightly, e.g. -10% to+20%; burial could vary from -50% to +200% or more.It has been TLG's experience that the results of a risk analysis, when compared with the base case estimate for decommissioning, indicate that the chances of the base decommissioning estimate's being too high is a low probability, and the chances that the estimate is too low is a higher probability.
This is mostly due to the pricing uncertainty for low-level radioactive waste burial, and to a lesser extent due to schedule increases from changes in plant conditions and to pricing variations in TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 3, Page 8 of 27 the cost of labor (both craft and staff). This cost study, however, does not include any additional costs for financial risk since there is insufficient historical data from which to project future liabilities.
Consequently, the areas of uncertainty or risk should be revisited periodically and addressed through repeated revisions or updates of the base estimate.3.5 SITE-SPECIFIC CONSIDERATIONS There are a number of site-specific considerations that affect the method for dismantling and removal of equipment from the site and the degree of restoration required.
The cost impact of the considerations identified below is included in this cost study. Unless otherwise noted, these assumptions are applicable to all three scenarios.
3.5.1 Spent
Fuel Management The cost to dispose of spent fuel generated from plant operations is not reflected within the estimates to decommission the TMI-2 site. The majority of the spent fuel was removed during the TMI-2 Clean-up Program's reactor vessel defueling effort which concluded in January 1990. Title to the spent fuel that was removed was transferred to the DOE.The remainder of the fuel (about 1%) is dispersed within the primary system and to a lesser extent in other systems and structures.
This residual material will be removed as radioactive waste and is included in the waste disposal volumes discussed in Section 5.Repository Availability There will be some wastes generated in the decommissioning of TMI-2 that are not suitable for shallow land burial and therefore cannot be shipped for disposal to either Barnwell or EnergySolutions.
This material, primarily associated with systems and structures contaminated with fuel debris, requires greater isolation from the environment.
For estimating purposes, a high-level waste repository, or some off site interim storage facility, is assumed to be available by 2020 for the disposal of this material.
This timetable is consistent with the Project Decision Schedule released by the Office of Civilian Radioactive Management in January 2009.TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 3, Page 9 of 27 3.5.2 Reactor Vessel and Internal Components The majority of the reactor internal components have already been removed as a result of the accident recovery effort in the 1980's. These components are currently being stored within the reactor building.
This estimate assumes that these components are segmented and shipped in shielded, reusable transportation casks commensurate with the start of major reactor vessel removal activities, e.g., Period 4A of the Delayed DECON scenario.The reactor pressure vessel and remaining internal components (essentially the core barrel, core former, thermal shield, and flow distributor) are segmented and packaged for disposal in shielded, reusable transportation casks. Segmentation of the remaining internal components is performed in the refueling canal, where a turntable and remote cutter are installed.
The vessel is segmented in place, using a mast-mounted cutter supported off the lower head and directed from a shielded work platform installed overhead in the reactor cavity.Transportation cask specifications and transportation regulations will dictate segmentation and packaging methodology.
It is anticipated that all neutron-activated components in the reactor vessel and internals would meet existing disposal requirements as delineated in 10 CFR §61, due to the short operating history. However, the fission products and transuranic material present on all surfaces in the vessel and internals are expected to exceed Class C limits, in particular for those components located below the top of the core. The reactor vessel and the upper portions of the internals are assumed to meet Class A limits following decontamination.
The dismantling of the reactor internals will generate radioactive waste considered unsuitable for shallow land disposal, i.e., GTCC. Although the material is not classified as high-level waste, the DOE has indicated it will accept this waste for disposal at the future high-level waste repository.[
2 2] However, the DOE has not been forthcoming with an acceptance criteria or disposition schedule for this material, and numerous questions remain as to the ultimate disposal cost and waste form requirements.
As such, for purposes of this study, the GTCC has been packaged and disposed of as high-level waste, at a cost of $25,000 per cubic foot. It is also assumed that the DOE will accept the GTCC material in a timely manner so as not to affect the TMI-2 decommissioning schedule.
No additional costs are included for the temporary storage of GTCC material.TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 3, Page 10 of 27 Intact disposal of the reactor vessel and internal components can provide savings in cost and worker exposure by eliminating the complex segmentation requirements, isolation of the GTCC material, and transport/storage of the resulting waste packages.
Portland General Electric (PGE) was able to dispose of the Trojan reactor as an intact package. However, its location on the Columbia River simplified the transportation analysis since: the reactor package could be secured to the transport vehicle for the entire journey, i.e., the package was not lifted during transport,* there were no man-made or natural terrain features between the plant site and the disposal location that could produce a large drop, and" transport speeds were very low, limited by the overland transport vehicle and the river barge.As a member of the Northwest Compact, PGE had a site available for disposal of the package -the US Ecology facility in Washington State.The characteristics of this arid site proved favorable in demonstrating compliance with land disposal regulations.
It is not known whether this option will be available for TMI-2. Future viability of this option will depend upon the ultimate location of the disposal site, as well as the disposal site licensee's ability to accept highly radioactive packages and effectively isolate them from the environment.
Consequently, the study assumes the reactor vessel will require segmentation, as a bounding condition.
3.5.3 Steam
Generators With the high levels of radioactivity and contamination both in the reactor building and within the steam generators, this estimate assumes that the steam generators will be segmented in place instead of one piece removal.The removal sequence assumed for the estimate is as follows: Remove the upper steam generator channel head by wire sawing the shell and tubes immediately below the upper tube sheet.Segment and decontaminate the upper channel head in the fuel transfer pool.TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 3, Page 11 of27* Install a steam generator work platform to allow in-place underwater segmentation of the steam generator internals.
- Remove the steam generator tubing and associated shroud and support plates.* Remove the steam generator cylindrical shell.* Remove the lower steam generator channel head." Segment and decontaminate the lower channel head in the fuel transfer pool.The steam generator tubing is packaged and shipped and buried as Class B waste. Steam generator tube support plates, shrouds, and shell plates are transported and buried as Class A waste. The estimate assumes that the steam generator channel heads will be decontaminated using a combination of machining and ultra high pressure (UHP) water sprays such that the components can be shipped and buried as Class A waste.Waste that is generated as a result of the machining and normal filtering of the water in the steam generators and the fuel transfer pool is assumed to be highly radioactive and is packaged and transferred to the DOE as GTCC waste.3.5.4 Other Primary System Components The following discussion deals with the decontamination, removal and disposition of the pressurizer, reactor coolant piping, reactor coolant pumps and motors, and the core flood tanks.A combination of in-place decontamination, and remote decontamination of components in the fuel transfer pool was assumed in the estimate.The pressurizer and the core flood tanks are decontaminated in-place using UHP. Once decontaminated, the pressurizer is cut in half, removed from the reactor building, grouted, and packaged in a shielded container for rail shipment and burial as Class A waste. The core flood tanks are assumed to be segmented, packaged and shipped as Class A waste.Hot leg piping is accessed by cutting a hole in the core barrel. A combination of underwater remote retrieval and vacuuming is used to remove fuel and fission product material.
Hot and cold leg piping and TLG Services, Inc.

Hydrolasing is used to remove radioactive materials.
Removed material is collected using filters and demineralizers, packaged, and transferred to the DOE as GTCC material.Decontaminated piping is packaged, shipped and buried as Class A waste.The reactor coolant pump motors are removed intact and placed in shielded containers for rail transport and burial as Class A material.Reactor coolant pumps are disassembled and placed in the fuel transfer pool for decontamination.
Pump components are decontaminated using UHP to remove the majority of the radioactive material.
Following decontamination, the components are packaged in shielded containers for rail transport and buried as Class A material.
Material removed as a result of the decontamination process is collected using filters and shipped as GTCC material.
The estimates also assume that process water used for reactor coolant system decontamination and in the fuel transfer pool is processed using cesium/strontium preferential cation demineralizers.
The resin waste is processed and buried as Class C radioactive waste.3.5.5 Other Systems Known to Contain High Levels of Radioactivity Systems in the reactor building and portions of systems in the auxiliary and fuel handling buildings are known to contain high levels of radioactivity and potentially spent fuel material from the accident.
The estimates recognize the difficulty in removing these components by increasing the work difficulty factors associated with removal of these systems. The estimates also assume that these components will be packaged for direct disposal (no recycling).
The disposal costs of these waste streams were also adjusted, as appropriate, to include curie surcharges commensurate with the higher radioactivity levels.These systems and components will be decontaminated with UHP sprays to removal fuel solids and sludge from fuel bearing components in the fuel and auxiliary buildings.
Solids and sludge resulting from the UHP process will be transferred to the reactor building to be packaged in canisters used for NSSS decontamination.

Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 3, Page 13 of 27 3.5.6 Reactor Building Structures Decontamination Significant radioactive contamination exists throughout the TMI-2 reactor building.
This contamination is due to fission products (9 0 Sr and 1 3 7 Cs in particular) released from the failed fuel. The radiation levels are not expected to decrease significantly from current levels due to the long half lives of these elements.
The dispersion of spent fuel within the reactor building includes alpha-decaying isotopes in addition to the beta and gamma radiation normally encountered during decommissioning.
These unusual conditions require additional controls and more engineered decommissioning methods to perform the structure decontamination and demolition.
Based upon these conditions, the estimates assume that the entire interior structure of the reactor building is removed and disposed as potentially contaminated material.The lower elevations of the reactor building are highly contaminated..
Significant activity has been absorbed in the concrete block walls, in the four foot thick D-ring concrete walls, and on the lower level concrete floors. Initial decontamination of this area (Period 4A) is assumed to be performed using remotely-operated machines (Brokk or equivalent).
Surface material will be bulk removed from the concrete walls, packaged in shielded casks and, on average concentration, buried as Class B waste (i.e., most of the debris mass will be Class A, but there will be hot spots ranging to Class C or GTCC).Once the highly contaminated surfaces are decontaminated, free standing concrete walls will be removed (in Period 4B using more conventional means) and shipped to a waste processor as radioactive waste.The upper portion of the containment inner steel liner and the entire polar crane will be removed using conventional radioactive demolition techniques (in Period 4B) and packaged, shipped and buried as radioactive waste. Following liner removal, the outer reactor building concrete walls will be removed using hydraulic excavation hammers.This remaining reactor building structural material will be surveyed on site, with 90% of the concrete volume assumed to meet free release criteria.
The remaining 10% is sent to a waste processor.
The free released concrete is acceptable for use as fill. Excess material and scrap metals will be sent to an industrial landfill.TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 3, Page 14 of 27 3.5.7 Demolition of Other Contaminated Structures Significant contamination exists within the auxiliary and fuel buildings.
Similar to the reactor building, locations within these buildings will require special engineered methods to safely decontaminate and dispose of the structures.
The estimate assumes that the entire auxiliary and fuel building structures (all walls and floors down to the footings) will be removed and the resultant structural material monitored and processed with the same criteria as the reactor building.Selected areas of the buildings will require remote operated machines and dedicated engineered ventilation systems and enclosures to allow decontamination and material removal.3.5.8 Main Turbine and Condenser The main turbine will be dismantled using conventional maintenance procedures.
The remaining turbine internals will be removed to a laydown area. The lower turbine casings will be removed from their anchors by controlled demolition.
This study recognizes that one of the low pressure turbine rotors has already been removed from the site. The main condensers will also be disassembled and moved to a laydown area.Material is then prepared for transportation to an off-site recycling facility where it will be surveyed and designated for either decontamination or volume reduction, conventional disposal, or controlled disposal.
Components will be packaged and readied for transport in accordance with the intended disposition.
3.5.9 Transportation
Methods Contaminated piping, components, and structural material other than the highly contaminated reactor coolant system components and reactor building structures will qualify as LSA-I, II or III or Surface Contaminated Object, SCO-I or II, as described in Title 49.[231 The contaminated material will be packaged in Industrial Packages (IP-1, IP-2 or IP-3, as defined in subpart 173.411) for transport unless demonstrated to qualify as their own shipping containers.
It is anticipated that the reactor vessel, due to its limited operating lifetime, will qualify as LSA II or III, once the reactor internals and remaining fuel debris is removed. The reactor vessel internal components are TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 3, Page 15 of 27 expected to be transported to the DOE's geologic repository in spent fuel casks by rail.Waste resulting from filtering and demineralization of the reactor coolant system, and processing the fuel transfer pool water is assumed to require shipment in shielded truck casks. Transport of other highly radioactive waste such as reactor coolant system components, and waste from the decontamination of the reactor building basement are by shielded truck cask. Truck cask shipments may exceed 95,000 pounds, including payload, supplementary shielding, cask tie-downs, and tractor-trailer. The maximum level of activity per shipment assumed permissible was based upon the license limits of the available shielded transport casks. The segmentation scheme for the vessel and internal segments is designed to meet these limits.The transport of large intact components, e.g., large heat exchangers and other oversized components are by a combination of truck, rail, and/or multi-wheeled transporter.
Truck transportation costs are estimated using published tariffs from Tri-State Motor Transit.[2 4 1 The low-level radioactive waste requiring controlled disposal will be sent to the EnergySolutions facility in Clive, Utah. Memphis, Tennessee, is used as the destination for off-site processing.
Bulk material shipped off site to the waste processor or to EnergySolutions is primarily moved via gondola railcars.3.5.10 Low-Level Radioactive Waste Disposal To the greatest extent practical, metallic material generated in the decontamination and dismantling processes is treated to reduce the total volume requiring controlled disposal.
The treated material, meeting the regulatory and/or site release criterion, is released as scrap, requiring no further cost consideration.
Conditioning and recovery of the waste stream is performed off site at a licensed processing center.Very low-level radioactive waste, e.g., structural steel and contaminated concrete, is sent to a waste processing facility.
More highly contaminated and activated material is sent to EnergySolutions.
Disposal fees are based upon current charges for operating waste. Since EnergySolutions does not currently have a license to handle and dispose of Class B and C wastes, Barnwell rates were used as a surrogate.
TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 3, Page 16 of 27 Surcharges were added for the highly activated components, e.g., generated in the segmentation of the reactor vessel. A nominal fee of$25,000 per cubic foot was assumed for the disposal of GTCC material at a federal repository.
The Idaho National Engineering and Environmental Laboratory (INEEL) is currently storing waste from the TMI-2 defueling operation.
Costs have been included in this estimate to pay INEEL for the final disposal of this waste; the timing of when this payment occurs will be dependent upon the. DOE's schedule for cleanup of INEEL. This estimate assumes that the payment occurs during Period 4 of each cost scenario.This study assumes that most of the concrete resulting from the demolition of the reactor, auxiliary and fuel handling buildings can be surveyed and released on site for fill of below grade voids, or shipped off site to a local construction debris landfill.
Should there be restrictions to this approach; the cost impact on the decommissioning program could become quite large, potentially up to tens of millions of-dollars.
3.5.11 Additional Decommissioning Facilities Additional specialized facilities are required in support of the decommissioning.
These include refurbishment of the containment air control envelope building located outside the reactor building equipment hatch, and the contamination control cubicle located outside the other personnel airlock, for reactor building radiological control and access.Construction of a prefabricated metal enclosure at 305 elevation within the reactor building for the handling of highly-contaminated material.
A radioactive waste packaging and processing facility will also be required (Note that such a facility already exists on site, but will require refurbishment).
3.5.12 Remediation of Soil and Underground Piping The estimates include the cost to remove certain underground piping.An allowance is also included for the removal, packaging, transportation and disposal of approximately 49,000 cubic feet of contaminated soil.3.5.13 Site Conditions Following Decommissioning The NRC will terminate (or amend) the site licenses if it determines that site remediation has been performed in accordance with the license TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 3, Page 17 of 27 termination plan, and that the termination survey and associated documentation demonstrate that the facility is suitable for release. The NRC's involvement in the decommissioning process will end at this point. Building codes and environmental regulations will dictate the next step in the decommissioning process, as well as the owner's own future plans for the site.Non-essential structures or buildings severely damaged in decontamination process are removed to a nominal depth of three feet below grade. Concrete rubble generated from demolition activities is processed and made available as clean fill. The excavations will be regraded such that the power block area will have a final contour consistent with adjacent surroundings.
This estimate assumes the reactor, auxiliary, fuel buildings will be removed completely, i.e., to their foundations and basemats.
Concrete from these buildings will be surveyed on-site using conventional monitoring equipment; concrete which meets the release criteria will be disposed of either on site as fill, or in an off-site landfill.3.6 ASSUMPTIONS The following are the major assumptions made in the development of the estimates for decommissioning the site.3.6.1 Estimating Basis The study follows the principles of ALARA through the use of work duration adjustment factors. These factors address the impact of activities such as radiological protection instruction, mock-up training, and the use of respiratory protection and protective clothing.
The factors lengthen a task's duration, increasing costs and lengthening the overall schedule.
ALARA planning is considered in the costs for engineering and planning, and in the development of activity specifications and detailed procedures.
Changes to worker exposure limits may impact the decommissioning cost and project schedule.All costs are reported in 2008 dollars.No costs have been included for the preparation of an environmental impact statement, should it be required.TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 3, Page 18 of 27 3.6.2 Labor Costs The craft labor required to decontaminate and dismantle the nuclear units will be acquired through standard site contracting practices.
The current cost of labor at the site is used as an estimating basis. Costs for site administration, operations, construction, and maintenance personnel are based upon average salary information provided by FirstEnergy or from comparable industry information.
FirstEnergy will provide limited oversight support staff in the areas of overall management, licensing, radiological and industrial safety and engineering.
It will also hire a DOC to provide the balance of the professional, management, administrative and physical staff.This study assumes that there is some sharing of security staffing positions with the adjacent Unit 1. This has the effect of slightly lowering site security costs.The staffing levels for the Hardened SAFSTOR scenario were adjusted (reduced) during decommissioning periods to reflect the two phase approach.3.6.3 Design Conditions Fuel cladding failure as a result of the accident will most likely prevent shipment of untreated major NSSS components under current transportation regulations and disposal requirements.
Therefore, this estimate assumes that aggressive mechanical decontamination of reactor coolant system components is required prior to shipment.The curie contents of the vessel and internals are activation products derived from those listed in NUREG/CR-3474.[
2 5 1 Actual estimates are derived from the curie/gram values contained therein and adjusted for the different mass of the TMI-2 components, the 95 effective full-power days, and different periods of decay. Additional short-lived isotopes were derived from CR-0130 [26] and CR-0672 [271 and benchmarked to the long-lived values from CR-3474. The activation products present in the reactor vessel base metal are assumed to be the controlling factor in their disposal, following surface decontamination of fuel debris.Reactor vessel internals whose elevation in the reactor places them at or below the original top of the fuel assemblies are assumed to be both sufficiently geometrically complex to preclude effective decontamination TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 3, Page 19 of 27 and contaminated with spent fuel so as to require disposal as GTCC material.Control elements and incore detector assemblies are assumed to have been removed with the damaged fuel.Activation of the reactor building structure and the biological shield is considered minimal due to the short operating life of TMI-2.3.6.4 General Transition Activities Existing warehouses will be cleared of non-essential material and remain for use by FirstEnergy and its subcontractors.
The plant's operating staff will perform the following activities at no additional cost or credit to the project during the transition period (FirstEnergy staff will be augmented as necessary, either by direct hiring, or by subcontracting to fulfill the staff requirements):
- Drain and collect lubricating oils for recycle and/or sale.* Process defueling waste inventories, i.e., the estimates include costs for the removal of lead shielding and spent fuel handling equipment that has remains in the reactor building.Scrap and Salvage Material located within the radiation controlled area, and not shipped for direct disposal, is sent off-site for survey and release.Furniture, tools, mobile equipment such as forklifts, trucks, bulldozers, and other property owned by FirstEnergy (and outside the radiation controlled area) is removed at no cost or credit to the decommissioning project. Disposition may include relocation to other facilities.
Spare parts are also available for alternative use.Energy For estimating purposes, the plant is assumed to be de-energized, with the exception of those facilities associated with long term dormancy.Replacement power costs are used for the cost of energy consumption TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 3, Page 20 of 27 during decommissioning for tooling, lighting, ventilation, and essential services.Insurance Costs for continuing coverage (nuclear liability and property insurance) during dormancy and decommissioning are included and based upon current operating premiums.
Reductions in premiums, throughout the decommissioning process, are based upon the guidance and the limits for coverage defined in the NRC's proposed rulemaking "Financial Protection Requirements for Permanently Shutdown Nuclear Power Reactors."[
2 8] The NRC's financial protection requirements are based on various reactor configurations.
Taxes Property taxes are not included.Site Modifications The perimeter fence and in-plant security barriers will be moved, as appropriate, to conform to the Site Security Plan in force during the various stages of the project.3.7 COST ESTIMATE

Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 4, Page I of 7 4. SCHEDULE ESTIMATE The schedules for the decommissioning scenarios considered in this study follow the sequence presented in the AIF/NESP-036 study, with minor changes to reflect recent experience and site-specific constraints.
A schedule or sequence of activities is presented in Figure 4.1 through 4.3 for the three decommissioning scenarios.
The key activities listed in the schedule do not reflect a one-to-one correspondence with those activities in the cost tables, but reflect dividing some activities for clarity and combining others for convenience.
The schedule was prepared using the "Microsoft Project 2003" computer software.i 2 9 1 4.1 SCHEDULE ESTIMATE ASSUMPTIONS The schedule reflects the results of a precedence network developed for the site decommissioning activities, i.e., a PERT (Program Evaluation and Review Technique)
Software Package. The work activity durations used in the precedence network reflect the actual man-hour estimates from the cost tables, adjusted by stretching certain activities over their slack range and shifting the start and end dates of others. The following assumptions were made in the development of the decommissioning schedule: 0 The dormancy period for each scenario begins on the TMI-1 shutdown date of April 19, 2034. The decommissioning preparation period for each scenario begins on the TMI-1 operating license termination date.* For the Custodial SAFSTOR scenario, onset of delayed decommissioning activities is commensurate with the termination of the TMI-1 operating license, following its 60 year SAFSTOR scenario.
Therefore, the custodial dormancy period ends, and delayed decommissioning activities begin at TMI-2 in 2084.* For the Hardened SAFSTOR scenario, final site restoration is completed 100 years after termination of the TMI-1 operating license.* All work (except vessel and internals removal and some of the decontamination of NSSS components in the refueling canal) is per-formed during an 8-hour workday, 5 days per week, with no overtime.There are eleven paid holidays per year.Steam generator removal activities are performed on multiple shifts with limited parallel work on the A and B steam generators.
TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 4, Page 2 of 7* Reactor and internals removal activities are performed by using separate crews for different activities working on different shifts, with a corresponding backshift charge for the second shift.* Multiple crews work parallel activities to the maximum extent possible, consistent with optimum efficiency, adequate access for cutting, removal and laydown space, and with the stringent safety measures necessary during demolition of heavy components and structures.
- For all scenarios, reactor building basement decontamination using remote equipment will occur prior to the start of reactor coolant system component removal.4.2 PROJECT SCHEDULE The period-dependent costs presented in the detailed cost tables are based upon the durations developed in the schedule for decommissioning TMI-2. Durations are established between several milestones in each project period; these durations are used to establish a critical path for the entire project. In turn, the critical path duration for each period is used as the basis for determining the period-dependent costs.Project timelines are provided in Figures 4.4 through 4.6.TLG Services, Inc.

RADIOACTIVE WASTES The objectives of the decommissioning process are the removal of all radioactive material from the site that would restrict its future use and the termination of the NRC license. This currently requires the remediation of all radioactive material at the site in excess of applicable legal limits. Under the Atomic Energy Act,[3 0 1 the NRC is responsible for protecting the public from sources of ionizing radiation.
Title 10 of the Code of Federal Regulations delineates the production, utilization, and disposal of radioactive materials and processes.
In particular, §71 defines radioactive material as it pertains to packaging and transportation and §61 specifies its disposition.
Most of the materials being transported for controlled burial are categorized as Low Specific Activity (LSA) or Surface Contaminated Object (SCO) materials containing Type A quantities, as defined in 49 CFR §173-178.
Shipping containers are required to be Industrial Packages (IP-1, IP-2 or IP-3, as defined in subpart 173.411).
For this study, commercially available steel containers are presumed to be used for the disposal of piping, small components, and concrete.
Larger components can serve as their own containers, with proper closure of all openings, access ways, and penetrations.
Table 5.1 summarizes the categories of radioactive waste streams, the disposal rate, and the conditions which applied to each category.The volumes of radioactive waste generated during the various decommissioning activities at the site is shown on a line-item basis in Appendices C, D, and E and summarized in Tables 5.2 through 5.4. The quantified waste volume summaries shown in these tables are consistent with §61 classifications.
The volumes are calculated based on the exterior dimensions for containerized material and on the displaced volume of components serving as their own waste containers.
The reactor vessel, internals, other reactor coolant system components, and certain structural materials are categorized as large quantity shipments and, accordingly, will be shipped in reusable, shielded truck casks with disposable liners or LSA boxes shipped within shielded vans. In calculating disposal costs, the burial fees are applied against the liner volume, as well as the special handling requirements of the payload.Most of the waste generated by the decommissioning process appears to be Class C or less, based upon the available information regarding the amount of fission products and transuranics present in the buildings, and the quantities of building materials assumed shipped as radioactive waste. This basis should be reexamined if TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 5, Page 2 of 6 additional characterization information becomes available in the future regarding the quantities of fission products and transuranics in more localized surveys.No process system containing/handling radioactive substances at the time of decommissioning is presumed to meet material release criteria by decay alone, i.e., systems radioactive in 2008 will still be radioactive over the time period during which the decommissioning is accomplished, due to the presence of long-lived radionuclides.
While the dose rates decrease with time, radionuclides such as 1 3 7 Cs will still control the disposition requirements.
The waste material generated in the decontamination and dismantling of TMJ-2 is primarily generated during Period 4 of the defined alternatives.
For purposes of constructing the estimates, the rate schedule for the Barnwell facility was used as a proxy for Class B and Class C waste. This schedule was used to estimate the disposal fees for plant components and concrete which are considered highly radioactive (unsuitable for processing or recovery).

Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 6, Page 1 of 5 6. RESULTS The analysis to estimate the costs to decommission TMI-2 relied upon the site-specific, technical information developed for previous analyses prepared in 1995-96 and 2004. While not an engineering study, the estimates provide FirstEnergy with sufficient information to assess its financial obligations, as they pertain to the eventual decommissioning of the nuclear station.The estimates described in this report are based on numerous fundamental assumptions, including regulatory requirements, project contingencies, radioactive waste disposal options, and site remediation requirements.
The decommissioning scenarios assume that the remainder of the spent fuel (less than 1%), which is dispersed throughout the reactor coolant and support systems, is packaged, shipped and buried as radioactive waste. Some of the waste that is generated is assumed to be GTCC. This waste is assumed to be transferred to the DOE at the time that it is processed and collected during the decommissioning.
No costs have been included for the temporary storage of GTCC material.The cost projected to decommission TMI-2, i.e., by the Delayed DECON alternative, is estimated to be $884 million. The majority of this cost (approximately 96%) is associated with the physical decontamination and dismantling of the nuclear unit so that the license can be terminated.
The remaining 4% is for the demolition of the designated structures and limited restoration of the site. The costs for the deferred decommission alternatives, Custodial SAFSTOR and Hardened SAFSTOR, are estimated at $923 million and $1,154 million, respectively.
The primary cost contributors, identified in Tables 6.1 through 6.3, are either labor-related or associated with the management and disposition of the radioactive waste.Program management is the largest single contributor to the overall cost. The magnitude of the expense is a function of both the size of the organization required to manage the decommissioning, as well as the duration of the program. It is assumed, for purposes of this analysis, that FirstEnergy will oversee the decommissioning program, using a DOC to manage the decommissioning labor force and the associated subcontractors.
The size and composition of the management organization varies with the decommissioning phase and associated site activities.
However, once the license is terminated, the staff is substantially reduced for the conventional demolition and restoration of the site.The cost for waste disposal includes only those costs associated with the controlled disposition of the radioactive waste generated from decontamination and dismantling activities, including plant equipment and components, structural material, filters, resins and dry-active waste. As described in Section 5, disposal of TLG Services, Inc.
Three Mile Island Unit 2 Document F07-1601-002, Rev. 0 Decommissioning Cost Analysis Section 6, Page 2 of 5 the lower level material, including concrete 'and structural steel, is at the EnergySolutions facility.
The more highly radioactive waste is sent to the EnergySolutions facility but using surrogate Barnwell waste burial rates. Highly contaminated components, requiring additional isolation from the environment, are packaged for geologic disposal.
The cost of geologic disposal is assumed to be$25,000 per cubic foot.Removal costs reflect the labor-intensive nature of the decommissioning process, as well as the management controls required to ensure a safe and successful program.Decontamination and packaging costs also have a large labor component that is based upon prevailing union wages. Non-radiological demolition is a natural extension of the decommissioning process. The methods employed in decontamination and dismantling are generally destructive and indiscriminate in inflicting collateral damage. With a work force mobilized to support decommissioning operations, non-radiological demolition can be an integrated activity and a logical expansion of the work being performed in the process of terminating the license.The reported cost for transport includes the tariffs and surcharges associated with moving large components and/or overweight shielded casks overland, as well as the general expense, e.g., labor and fuel, of transporting material to the destinations identified in this report. I License termination survey costs are associated with the labor intensive and complex activity of verifying that contamination has been removed from the 'site to the levels specified by the regulating agency. This process involves a systematic survey of all remaining plant surface areas and surrounding environs, sampling, isotopic analysis, and documentation of the findings.
The status of any plant components and materials not removed in the decommissioning process will also require confirmation and will add to the expense of surveying the facilities alone.Due to the complete removal of the reactor, auxiliary and fuel buildings, the final termination survey effort is reduced.The remaining costs include allocations for heavy equipment and temporary services, as well as for other expenses such as regulatory fees and the premiums for nuclear insurance.

year, oft expenditure.
Financial r~~~ ~ autdfr MI:-sched ules are provided for lthe three: deconmimss'ioning scenarios eval uat0ed for TM-.2. The sebnarios assuume that, Exelbon, Genciiation (thee Owner. and operator of the adjacent Unit 1) wiill be successful -in, extending thl operating I-ccns~e for Unit. 1 (TMI- 1) to 2034. The TMI-2 decommissioning scenarios are def'ned as follows: 1 Delayed DECON: Oine of' the decommissioning alternatives for Unit 1 is to defer decommissioning until the spent fuel has been removed from the site.This scenario assumes that the decontamination and dismantling activities at TmI-2 are synchronized with the adjacent unit such that the licenses for both units are terminated concurrently.
2,. Custodial SAFSTOR: In the second scenario, TMI.I71 is placed inito long-terih storage. TMI-2 remains in storage until. such time that decommissioning activities can be coordinated
\Vith Unit 1. ,As with the, first Scenario, termination of the.licenses i's coordin'ated..
- 3. Hardened SAFSTOR: This scenario assumes that Unit 1 is promptly decommissioned when it ceases operations in 2034. In coordination with the Unit 1 activities, the TMI-2 reactor building is reconfigured for long-term, passive storage. Site structures and facilities, with the exception of the reactor building, are, deeontaaminated and dismantled.
The reactor building and its contents aire secu.ed and the site is reconfigured fo-r monitored 7SurIPVeillance.
Decontaminilation and final diis3mantling of' the reactor building is deferred 'for approximately-100 years (fr'onii Uniiit I shutdown).
For each of the three scenarios described above, .dorinancy costs are.accrued from the 6ees'ation.
ofTMI- 1 Operations in 2034. This mieans that the current PDMS costs are not included within the reported decommissioning costs.Background The Nuclear Regulatory Commission (NRC) provided initial decommissioning requirements in its rule adopted on June 2.7, 1988. In this rule, the NR.C set forth financial criteria for decommnission!ing licensed nuclear .power facilities.
As part of the prTcess to demonstrate financial assurance, licensees must adjust the estimate of' the cost of decominissioning their plants; in dollars. of the current. year (10 CFR§50.75). To- facilitate the process, :and. provide .unifoi~mity ini reijorting, thei NRC T'LG Services, hec; Three Mile Island Unit 2 DoAume(t F07.1601.004, Rev. 0 Financial EsLalation, Analysis Page 6 (f23 ,pereiodically reissues NUREG-.13071 "Repot on Waste Burial Charges." T]his document develops the basis for the escalation.of waste disposal costs (since 1-986).and idefiti:fies the hpjMopriate indices foi, the labor- and energy .cost con 6nents.While tihe burial index is burial site-specific, labor escalation is tied, to the Employment Cost Index published by the U.S. Department of Labor, Bureau of Labor Statistics (BLS) and energy to the Producer Price Index.For purposes of escalation, the NRC divides its reference costs for decommissioning into categories of labor, energy, and burial. TLG also allocates its costs, for decommissioning into categories, with the, NRC's labor category further subdivided into "labor"' and "equipmient and matevriails.
and :an "oýher" category added for miscellaneious fees, taxes and 'other unique or. onet~ime expe.,nditures.
The Financial Accounting Stanidards Board (FASB) issued a. Statement of Financial Accounting Standards, No. 143 (FAS 143) in 2001. The Stagtement acddessed financial accounting and reporting for obligations associated with the retirement, of tangible long-lived assets and the associated asset reti'rement costs.TLC, has prepared ARO liability assessments (partial or total) for several major nuclear plant owners. The assessments follow the process outlined in FAS 143 and have been reviewed and deemed acceptable by the owner's financial auditors.FAS 143 allows for estimating the fair value 'of anl ARO liability by using an expected, present value technique.
FAS 143 states in paragraph.
8: I'f a present value technique is used to estimate fair value, estimates of'ftlU.tre cash flows, used in that technique shall be consistent wlth the objectPive ofimeasuring f.ir value." PLG develops future cash flows by escalating four of the&cost; categories (labor, equipment and materials, energy and other) with indices provided by 11IS Global Insight (IHS Global Insight is a privately held company which acquired Global Insight in 2008. The combined company includes well-known businesses such as Cambridge Energy Research Associates (CERA), Jane's Information Group, and I-S Herold; it also includes the former companies known as DRI (Data Resources, Inc.) and WEFA (Wh-arton Econometric; Forecasting:
Associates)).
For this analysis, the escalation rate for Burial had been established through an: agreement, between FirstEnergy and EnergySolutionis, the disposal servi'ce promidcer.-Since the, timefrafi0e " of decominisioning, typically exceeds that of the pu.)bished indices, for years beyond the published index, the inflation factor is determined using a "moving-average" method, averaging the most recen't 25 years of indices to determine the future year index.TLG Services, Ine.

Index Selection Table 5 identifies the Global Insight forecast data sets used for the four cost.categories (exclusive of Burial). Consistent with the NRC's guidance, TLG escalates the labor component, of its decommissioning cost; estimates using an Employment Cost Index (ECI) and the eneirgy cost with a Producer Price 1.ncdex (PP.I).Use of the Consumer Price Index (CPI)for general services, site ýopeirating costs and one.ime expenditures is consistent With the. initent of the index (the measure of the average, change, in prices, over, time of goods and services).
The decommissioning process is labor intensive, with labor representing more than half of the total cost. The estimates for TMI-2 include the cost: of the craft, labor performing field activities, the field supervision and support services, project, management, administration, security, and costs for specialty contractors.
The Employment Cost: Index (fCI) is a qluarterly measure of changes in labor costs. It is one of the principal economic indicators used by the Fcederal Reserve Bank, The index shows changes in wages and salaries andc benefit; costs, as .well as, chainges in.total conmpensation The ECIPCTNS index, provided by (]'lobbl Insigh-rt, is aq yearly estinAte of ch'ange in the cost of labor, defined as compensationl Iper miployee hour worked..
