Subject:

Submittal of Preliminary Decommissioning Cost Estimate and Spent Fuel Management Plan

Reference:

1) Letter from John G. Lamb (U. S. Nuclear Regulatory Commission) to Michael J. Pacilio (Exelon Generation Company, LLC), "Oyster Creek Nuclear Generating Station - Request for Information Regarding Preliminary Decommissioning Cost Estimate and Annual Decommissioning Funding Status Reports," dated September 17, 2014 (ML14252A703)

2) Letter RA-11-007 from Keith R. Jury (Exelon Generation Company, LLC) to U.S. Nuclear Regulatory Commission, "Permanent Cessation of Operations at Oyster Creek Nuclear Generating Station," dated January 7, 2011 (ML110070507)

Exelon Generation Company, LLC (Exelon) is submitting this letter to provide a preliminary decommissioning cost estimate pursuant to 10 CFR 50.75(f)(3) and spent fuel management plan pursuant to 10 CFR 50.54(bb) 1 for Oyster Creek Nuclear Generating Station (OCNGS).

In accordance with 10 CFR 50.75, "Reporting and recordkeeping for decommissioning planning," paragraph (f)(3), "Each power reactor licensee shall at or about 5 years prior to the projected end of operations submit a preliminary decommissioning cost estimate which includes an up-to-date assessment of the major factors that could affect the cost to decommission." of this submittal contains a preliminary decommissioning cost estimate for OCNGS. The cost estimate is a preliminary estimate of anticipated costs and will be updated at various times as deemed appropriate by OCNGS and/or in compliance with regulatory requirements. The attached preliminary decommissioning cost estimate assumes that OCNGS permanently terminates operations on December 31, 2019, in accordance with the Reference 2 letter.

1 Section 50.54(bb) requires that licensees submit a spent fuel management plan to the NRC within two years following permanent shutdown or five years prior to the expiration of the operating license. The operating license for Oyster Creek Nuclear Generating Station expires in 2029. In Reference 2, Exelon provided notice of its intention to permanently cease operations effective December 31, 2019. As a result, Exelon is providing its spent fuel management plan within five years of the shutdown date.

U.S. Nuclear Regulatory Commission Submittal of Preliminary Decommissioning Cost Estimate and Spent Fuel Management Plan Docket Nos. 50-219 and 72-15 December 30, 2014 Page 2 The major factors that could affect the cost estimate as well as contingencies to allow for unknown or unplanned occurrences during decommissioning are included in the attached preliminary decommissioning cost estimate. Additionally, soil and ground water remediation costs are included in the cost estimate. The required soil remediation is based on a report that evaluated the known or suspected contaminated soil at OCNGS as of January 2004 and evaluation of subsequent 10 CFR 50.75(g)(1) reports.

The attached preliminary decommissioning cost estimate evaluates three (3) options for decommissioning OCNGS. Exelon has not made a final determination of the decommissioning approach for OCNGS. For the purpose of choosing a decommissioning option to demonstrate adequacy of funding to meet regulatory requirements, the SAFSTOR option has been selected. Exelon reserves the right to choose a decommissioning option in accordance with its business needs, recognizing that it needs to assure the chosen option meets U.S. Nuclear Regulatory Commission (NRC) requirements for decommissioning funding.

As discussed in 10 CFR 50.54(bb), Conditions of licenses, paragraph (bb), a licensee shall submit written notification to the Commission for its review and preliminary approval of the program by which the licensee intends to manage and provide funding for the management of all irradiated fuel at the reactor following permanent cessation of operation of the reactor until title to the irradiated fuel and possession of the fuel is transferred to the Secretary of Energy for its ultimate disposal in a repository.

Accordingly, Attachment 2 of this submittal includes the Spent Fuel Management Plan for NRC review and preliminary approval. contains the projected annual cash flow required for decommissioning OCNGS based on the SAFSTOR scenario from the Attachment 1 cost estimate. (The cost estimate is in thousands of 2011 dollars. The Attachment 1 costs have been escalated to 2014 dollars in Attachment 3.) The costs for radiological decommissioning (license termination costs), spent fuel management, Independent Spent Fuel Storage Installation (ISFSI) decommissioning, and site restoration (non-radiological decommissioning) are reflected in Attachment 3. Exelon recognizes that an exemption from 10 CFR 50.82(a)(8)(i)(A) is required to use decommissioning trust funds for expenses other than decommissioning activities as the term decommissioning is defined in 10 CFR 50.2. contains the projected annual cash flow from the OCNGS decommissioning trust fund for decommissioning the site (including radiological decommissioning, spent fuel management, ISFSI decommissioning, and site restoration) based on the SAFSTOR scenario from the Attachment 1 cost estimate. The cash flow analysis conservatively assumes all expenses in a year are incurred at the beginning of year (i.e., beginning of year convention) during the decommissioning period.

U.S. Nuclear Regulatory Commission Submittal of Preliminary Decommissioning Cost Estimate and Spent Fuel Management Plan Docket Nos. 50-219 and 72-15 December 30, 2014 Page 3 As of November 30, 2014, OCNGS decommissioning trust fund balances totaled $869.9 million. Escalated at 2% annual real rate of return to November 30, 2019, the trust fund will amount to $960.5 million before deducting decommissioning expenses, which exceeds the amount required to complete decommissioning of the site under the SAFSTOR scenario of the attached preliminary cost estimate.

In accordance with 10 CFR 50.54(bb), a copy of this notification will be maintained until the expiration of the OCNGS operating license. Additionally, OCNGS will notify the NRC of any significant changes in the proposed Spent Fuel Management Plan described in .

There are no new regulatory commitments contained in this letter.

SUMMARY

This report presents updated estimates of the cost to decommission the Oyster Creek Nuclear Generating Station (Oyster Creek) for the identified decommissioning scenarios following a scheduled cessation of plant operations. The analysis relies upon site-specific, technical information, originally developed in an evaluation for the GPU Nuclear Corporation in 1997-99,[1] revised in subsequent evaluations in 2003-04[2] and 2008-09,[3] and finally 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 Exelon Generation Company (Exelon) with sufficient information to assess its financial obligations as they pertain to the eventual decommissioning of the nuclear station.

The primary goal of the decommissioning is the removal and disposal of the contaminated systems and structures so that the plants operating license can be terminated. The analysis recognizes that spent fuel will be stored at the site in the plants storage pool and/or in an independent spent fuel storage installation (ISFSI) until such time that it can be transferred to a Department of Energy (DOE) facility.

Consequently, the estimates also include those costs to manage and subsequently decommission such storage facilities.

The estimates are based on numerous fundamental assumptions, including regulatory requirements, low-level radioactive waste disposal practices, high-level radioactive waste management options, site restoration requirements, and project contingencies. The estimates incorporate a minimum cooling period of approximately five and one-half years for the spent fuel that resides in the reactor building storage pool when operations cease. 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.[4] In this rule, 1

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Page viii of xix 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 removed or decontaminated to a level that permits the property to be released for unrestricted use shortly after cessation of operations."[5]

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."[6] 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."[7] As with the SAFSTOR alternative, decommissioning is currently required to be completed within 60 years.

The 60-year restriction has limited the practicality for 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 based upon several factors (e.g., no licensee has committed to pursuing the entombment option, the unresolved issues associated with the disposition of greater-than-Class C material (GTCC), and the NRCs current priorities) at least until after the additional research studies are complete. The Commission concurred with the staffs recommendation.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Page ix of xix In 1996 the NRC amended its decommissioning regulations to clarify ambiguities and codify procedures and terminology as a means of enhancing efficiency and uniformity in the decommissioning process.[8] 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 amendments 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 these regulations.

Decommissioning Scenarios The following scenarios were evaluated and are representative of the alternatives available to the owner. The current operating license expires in 2029; however, this study assumes that the plant will retire in 2019.

1. DECON: Decommissioning activities commence shortly after the cessation of plant operations. The spent fuel in the plants spent fuel storage pool is transferred to the ISFSI within five and one-half years. The equipment, structures, and portions of the plant containing radioactive contaminants are removed or decontaminated to a level that permits the facility to be released for unrestricted use. Non-essential structures are then demolished. Spent fuel storage operations continue at the site (ISFSI) until the transfer of the fuel to the DOE is complete, assumed to be in the year 2036.

2. Delayed DECON: In the second scenario, the unit is shutdown and prepared for dismantling similar to the DECON scenario; however, in this scenario, the unit enters an abbreviated period of storage prior to the actual start of field activities. The spent fuel discharged to the storage pool once operations cease remains in the pool until it can be transferred to a DOE facility. The ISFSI, used to support operations, is not used to off-load the storage pool.

Decommissioning is delayed until the transfer of the fuel from both the pool and ISFSI to the DOE is completed in the year 2036. The unit is then decommissioned.

3. SAFSTOR: The unit is placed into safe-storage in the third scenario.

Decommissioning is deferred beyond the fuel storage period to the maximum extent possible; termination of the license would conclude within the required 60-year period. The spent fuel in the plants spent fuel storage pool is 8

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Page x of xix transferred to the ISFSI within five and one-half years. Spent fuel storage operations continue at the site until the transfer of the fuel to the DOE is complete, assumed to be in the year 2036. The plant remains in safe-storage following the removal of spent fuel from the site, timed to allow final decommissioning and license termination to be completed within 60 years of final shutdown. As with the first two scenarios, decommissioning activities are sequenced and integrated so as to minimize the total duration of the physical dismantling process.

Methodology The methodology used to develop the estimates described within this document follows the basic approach originally presented in the cost estimating guidelines [9]

developed by the Atomic Industrial Forum (now Nuclear Energy Institute). This reference describes a unit factor method for determining decommissioning activity costs. The 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 standard cost estimating practice, contingencies are applied to the decontamination and dismantling costs 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.[10] 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 9

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Page xi of xix used in this analysis, does not account for price escalation and inflation in the cost of decommissioning over the remaining operating life of the station.

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 material is suitable for shallow-land disposal. With the passage of the Low-Level Radioactive Waste Policy Act in 1980,[11] and its Amendments of 1985,[12] the states became ultimately responsible for the disposition of low-level radioactive waste generated within their own borders.

New Jersey is a member of the three-state Atlantic Interstate Low-Level Radioactive Waste Management Compact, formed after South Carolina formally joined the Northeast Regional Compact. The Barnwell Low-Level Radioactive Waste Management Facility located in South Carolina is expected to be available to support the decommissioning of Oyster Creek. It is also assumed that Exelon can access other disposal sites, should it prove cost-effective. As such, rate schedules for both the Barnwell and the EnergySolutions facility in Clive, Utah are used to generate disposal costs.

For the purpose of this analysis, the EnergySolutions facility is used as the basis for estimating the disposal cost for the lowest level and majority of the radioactive waste (Class A [13]). EnergySolutions does not have a license to dispose of the more highly radioactive waste (Classes B and C), for example, generated in the dismantling of the reactor vessel. The disposal cost for this material is based upon the rate schedule for the Barnwell facility.

The dismantling of the components residing closest to the reactor core generates radioactive waste considered unsuitable for shallow-land disposal (i.e., low-level radioactive waste with concentrations of radionuclides that exceed the limits established by the NRC for Class C radioactive waste (GTCC)). The Low-Level 11 Low-Level Radioactive Waste Policy Act of 1980, Public Law 96-573, 1980 12 Low-Level Radioactive Waste Policy Amendments Act of 1985, Public Law 99-240, 1986 13 U.S. Code of Federal Regulations, Title 10, Part 61, Licensing Requirements for Land Disposal of Radioactive Waste TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Page xii of xix Radioactive Waste Policy Amendments Act of 1985 assigned the federal government the responsibility for the disposal of this material. The Act also stated that the beneficiaries of the activities resulting in the generation of such radioactive waste bear all reasonable costs of disposing of such waste. However, to date, the federal government has not identified a cost for disposing of GTCC or a schedule for acceptance. As such, the GTCC radioactive waste in this study is assumed to be packaged and disposed of as high-level waste, at a cost equivalent to that envisioned for the spent fuel.

The GTCC material is either stored with the spent fuel at the ISFSI or shipped directly to a DOE facility as it is generated (depending upon the timing of the decommissioning and whether the spent fuel has been removed from the site prior to the start of decommissioning).

A significant portion of the waste material generated during decommissioning may only be potentially contaminated by radioactive materials. This waste can be analyzed 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 for Oyster Creek reflect the savings from waste recovery/volume reduction.

High-Level Radioactive Waste Management Congress passed the Nuclear Waste Policy Act (NWPA) in 1982, assigning the federal governments long-standing responsibility for disposal of the spent nuclear fuel created by the commercial nuclear generating plants to the DOE. The DOE was to begin accepting spent fuel by January 31, 1998; however, to date no progress in the removal of spent fuel from commercial generating sites has been made.

Today, the country is at an impasse on high-level waste disposal, even with the License Application for a geologic repository submitted by the DOE to the NRC in 2008. The current Administration has cut the budget for the repository program while promising to conduct a comprehensive review of policies for managing the back end of the nuclear fuel cycle and make recommendations for a new plan.[14]

Towards this goal, the Administration appointed a Blue Ribbon Commission on Americas Nuclear Future (Blue Ribbon Commission) to make recommendations for 14 Blue Ribbon Commission on Americas Nuclear Future Charter, http://cybercemetery.unt.edu/archive/brc/20120620215336/http://brc.gov/index.php?q=page/charter TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Page xiii of xix a new plan for nuclear waste disposal. The Blue Ribbon Commissions charter includes a requirement that it consider [o]ptions for safe storage of used nuclear fuel while final disposition pathways are selected and deployed.[15]

On January 26, 2012, the Blue Ribbon Commission issued its Report to the Secretary of Energy containing a number of recommendations on nuclear waste disposal. Two of the recommendations that may impact decommissioning planning are:

[T]he United States [should] establish a program that leads to the timely development of one or more consolidated storage facilities[16]

[T]he United States should undertake an integrated nuclear waste management program that leads to the timely development of one or more permanent deep geological facilities for the safe disposal of spent fuel and high-level nuclear waste.[17]

In January 2013, the DOE issued the Strategy for the Management and Disposal of Used Nuclear Fuel and High-Level Radioactive Waste, in response to the recommendations made by the Blue Ribbon Commission and as a framework for moving toward a sustainable program to deploy an integrated system capable of transporting, storing, and disposing of used nuclear fuel...[18]

With the appropriate authorizations from Congress, the Administration currently plans to implement a program over the next 10 years that:

Sites, designs and licenses, constructs and begins operations of a pilot interim storage facility by 2021 with an initial focus on accepting used nuclear fuel from shut-down reactor sites; Advances toward the siting and licensing of a larger interim storage facility to be available by 2025 that will have sufficient capacity to provide flexibility in the waste management system and allows for acceptance of enough used nuclear fuel to reduce expected government liabilities; and 15 Ibid.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Page xiv of xix Makes demonstrable progress on the siting and characterization of repository sites to facilitate the availability of a geologic repository by 2048.[19]

The NRCs review of DOEs license application to construct a geologic repository at Yucca Mountain was suspended in 2011 when the Administration slashed the budget for completing that work. However, the US Court of Appeals for the District of Columbia Circuit recently issued a writ of mandamus (in August 2013) [20]

ordering NRC to comply with federal law and restart its review of DOE's Yucca Mountain repository license application to the extent of previously appropriated funding for the review.

Completion of the decommissioning process is dependent upon the DOEs ability to remove spent fuel from the site in a timely manner. DOEs repository program had assumed that spent fuel allocations would be accepted for disposal from the nations commercial nuclear plants, with limited exceptions, in the order (the queue) in which it was discharged from the reactor.[21] With a large fleet of reactors, Exelon may be able to re-assign allocations between its units to minimize on-site storage costs.

Assuming a 2025 start date for DOE initiating transfer of commercial spent fuel to a federal facility (based upon the proposed timeline for the availability of the larger interim storage facility), the assemblies generated from Oyster Creek operations are projected to be shipped from the Oyster Creek site in the years 2034 through 2036 (assuming the cessation of plant operations in 2019). This equates to 76 multi-purpose canisters (at 61 assemblies per canister).

An ISFSI, operated under a Part 50 General License (in accordance with 10 CFR 72, Subpart K[22]), has been constructed to support continued plant operations.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Page xv of xix analysis assumes that the facility can be expanded to support decommissioning operations (in the DECON and SAFSTOR scenarios).

The spent fuel in the wet storage pools at the cessation of plant operations is expected to be transferred to the ISFSI (DECON and SAFSTOR scenarios) within the first five and one-half years following shutdown. Once the wet storage pool is emptied, the reactor building can be either decontaminated and dismantled or prepared for long-term storage. The pool is kept operational in the Delayed DECON scenario until the spent fuel stored in the pool can be transferred to the DOE.

Exelons strongly held position is that the DOE has a contractual obligation to accept Oyster Creeks fuel in a timely manner and consistent with its contract commitments. No assumption made in this study should be interpreted to be inconsistent with this claim. However, at this time, including the cost of storing spent fuel in this study is the most reasonable approach because it insures the availability of sufficient decommissioning funds at the end of the stations life if the DOE has not met its contractual obligation to take the fuel.

Site Restoration The efficient removal of the contaminated materials at the site will 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.

Consequently, this analysis assumes that non-essential site structures within the restricted access area are removed to a nominal depth of three feet below the local grade level wherever possible. The site is then graded and stabilized.

Summary The costs to decommission Oyster Creek were evaluated for several decommissioning scenarios, incorporating the attributes of both the DECON and SAFSTOR decommissioning alternatives. Regardless of the timing of the decommissioning activities, the estimates assume the eventual removal of all the contaminated and activated plant components and structural materials, such that TLG Services, Inc.

Delayed decommissioning is initiated after the spent fuel has been removed from the site and is accomplished within the 60-year period required by current NRC regulations. In the interim, the spent fuel remains in storage at the site until such time that the transfer to a DOE facility can be completed. Once the transfer is complete, the storage facilities are also decommissioned.

1. INTRODUCTION This report presents updated estimates of the cost to decommission the Oyster Creek Nuclear Generating Station (Oyster Creek), for the scenarios described in Section 2, following a scheduled cessation of plant operations. The analysis relies upon site-specific, technical information from an earlier evaluation prepared in 2008-09,[1] updated to reflect current assumptions pertaining to the disposition of the nuclear unit and relevant industry experience in undertaking such projects. The current estimates are designed to provide Exelon Generation Company (Exelon),

with sufficient information to assess their 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 objectives of this study are to prepare comprehensive estimates of the cost to decommission Oyster Creek, to provide a sequence or schedule for the associated activities, and to develop waste stream projections from the decontamination and dismantling activities. The plants operating license currently expires on April 9, 2029; however, this study assumes that the plant will be retired on December 31, 2019.

1.2 SITE DESCRIPTION The Oyster Creek nuclear unit is about two miles inland from the shore of Barnegat Bay on the coast of New Jersey. The site is approximately nine miles south of Toms River, New Jersey; about fifty miles east of Philadelphia, Pennsylvania; and sixty miles south of Newark, New Jersey. The generating station is comprised of a single reactor with supporting facilities.

Oyster Creek was designed and constructed by the General Electric Company Atomic Power Equipment Department as a turnkey project. The reactor is a single-cycle, forced circulation boiling water reactor producing steam for direct use in the steam turbine. The reactor vessel and the recirculation system are contained within the drywell of a pressure absorption containment system housed within the reactor building. The primary containment system consists of the drywell, vent pipes, and a pool of water contained in the absorption chamber (torus). The reactor building encloses the primary containment system, thereby providing a secondary containment.

TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 1, Page 2 of 9 Oyster Creek presently operates under a full term operating license at a maximum thermal power level of about 1930 MWth with a corresponding gross electrical output of approximately 670 MWe. Heat produced in the reactor is converted to electrical energy by the steam and power conversion system. A turbine-generator system converts the thermal energy of steam produced by the reactor into mechanical shaft power and then into electrical energy. The turbine consists of a high-pressure, double-flow turbine element and three double-flow, low-pressure turbine elements all aligned in tandem. The generator is a direct-driven 60 Hertz, 24,000 volt, conductor-cooled, synchronous generator rated at 687,500 kVA. The turbine is operated in a closed feedwater cycle which condenses the steam; the heated feedwater is returned to the reactor. Heat rejected in the main condensers is removed by the circulating water system.

The circulating water system provides the heat sink required for removal of waste heat in the power plants thermal cycle. Water is drawn from Barnegat Bay through a 140 foot wide intake canal which follows the general course of the south branch of Forked River. The system has the principal function of removing heat by absorbing this energy in the main condenser. After passing through the plant condensers, the water is routed through the discharge canal which empties into Barnegat Bay.

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.[2]* 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,[3] 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.

• Annotated references for citations in Sections 1-6 are provided in Section 7.

TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 1, Page 3 of 9 The rule defined three decommissioning alternatives as being acceptable to the NRC: DECON, SAFSTOR, and ENTOMB. The DECON alternative assumes that any contaminated or activated portion of the plants 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 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.

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.[4] 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. However, the staff also found that additional rulemaking would be needed before this option could be treated as a generic alternative. The NRC had considered rulemaking to alter the 60-year time for completing decommissioning and to clarify the use of engineered barriers for reactor entombments.[5] However, the NRCs staff has recommended that rulemaking be deferred, based upon several factors, e.g., no licensee has committed to pursuing the entombment option, the unresolved issues associated with the disposition of greater-than-Class C material (GTCC), and the NRCs current priorities, at least until after the additional research studies are complete. The Commission concurred with the staffs recommendation.

The NRC published amendments to its decommissioning regulations in 1996.[6]

When the regulations were originally adopted in 1988, it was assumed that the majority of licensees would decommission at the end of the facilitys operating 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 TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 1, Page 4 of 9 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.

Under the revised regulations, licensees will submit written certification to the NRC within 30 days after the decision to cease operations. Certification will also be required once the fuel is permanently removed from the reactor vessel.

Submittal of these notices will entitle the licensee to a fee reduction and eliminate the obligation to follow certain requirements needed only during operation of the reactor. Within two years of submitting notice of permanent cessation of operations, the licensee is required to submit a Post-Shutdown Decommissioning Activities Report (PSDAR) to the NRC. The PSDAR describes the planned decommissioning activities, the associated sequence and schedule, and an estimate of expected costs. Prior to completing decommissioning, the licensee is required to submit applications to the NRC to terminate the license, which will include a License Termination Plan (LTP).

1.3.1 Nuclear Waste Policy Act Congress passed the Nuclear Waste Policy Act (NWPA) in 1982,[7]

assigning the federal governments long-standing responsibility for disposal of the spent nuclear fuel created by the commercial nuclear generating plants to the DOE. The DOE was to begin accepting spent fuel by January 31, 1998; however, to date no progress in the removal of spent fuel from commercial generating sites has been made.

Today, the country is at an impasse on high-level waste disposal, even with the License Application for a geologic repository submitted by the DOE to the NRC in 2008. The current Administration has cut the budget for the repository program while promising to conduct a comprehensive review of policies for managing the back end of the nuclear fuel cycle and make recommendations for a new plan.

Towards this goal, the Administration appointed a Blue Ribbon Commission on Americas Nuclear Future (Blue Ribbon Commission) to make recommendations for a new plan for nuclear waste disposal. The Blue Ribbon Commissions charter includes a requirement that it consider [o]ptions for safe storage of used nuclear fuel while final disposition pathways are selected and deployed.[8]

On January 26, 2012, the Blue Ribbon Commission issued its Report to the Secretary of Energy containing a number of recommendations on TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 1, Page 5 of 9 nuclear waste disposal. Two of the recommendations that may impact decommissioning planning are:

[T]he United States [should] establish a program that leads to the timely development of one or more consolidated storage facilities

[T]he United States should undertake an integrated nuclear waste management program that leads to the timely development of one or more permanent deep geological facilities for the safe disposal of spent fuel and high-level nuclear waste.[9]

In January 2013, the DOE issued the Strategy for the Management and Disposal of Used Nuclear Fuel and High-Level Radioactive Waste, in response to the recommendations made by the Blue Ribbon Commission and as a framework for moving toward a sustainable program to deploy an integrated system capable of transporting, storing, and disposing of used nuclear fuel...[10]

With the appropriate authorizations from Congress, the Administration currently plans to implement a program over the next 10 years that:

Sites, designs and licenses, constructs and begins operations of a pilot interim storage facility by 2021 with an initial focus on accepting used nuclear fuel from shut-down reactor sites; Advances toward the siting and licensing of a larger interim storage facility to be available by 2025 that will have sufficient capacity to provide flexibility in the waste management system and allows for acceptance of enough used nuclear fuel to reduce expected government liabilities; and Makes demonstrable progress on the siting and characterization of repository sites to facilitate the availability of a geologic repository by 2048.

The NRCs review of DOEs license application to construct a geologic repository at Yucca Mountain was suspended in 2011 when the Administration slashed the budget for completing that work. However, the US Court of Appeals for the District of Columbia Circuit recently issued a writ of mandamus (in August 2013)[11] ordering NRC to comply with federal law and restart its review of DOE's Yucca Mountain TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 1, Page 6 of 9 repository license application to the extent of previously appropriated funding for the review.

Completion of the decommissioning process is dependent upon the DOEs ability to remove spent fuel from the site in a timely manner.

DOEs repository program had assumed that spent fuel allocations would be accepted for disposal from the nations commercial nuclear plants, with limited exceptions, in the order (the queue) in which it was discharged from the reactor.[12] With a large fleet of reactors, Exelon may be able to re-assign allocations between its units to minimize on-site storage costs.

Assuming a 2025 start date for DOE initiating transfer of commercial spent fuel to a federal facility (based upon the proposed timeline for the availability of the larger interim storage facility), the assemblies generated from Oyster Creek operations are projected to be shipped from the Oyster Creek site in the years 2034 through 2036 (assuming the cessation of plant operations in 2019). This equates to 76 multi-purpose canisters (at 61 assemblies per canister).

An ISFSI, operated under a Part 50 General License (in accordance with 10 CFR 72, Subpart K[13]), has been constructed to support continued plant operations. This analysis assumes that the facility can be expanded to support decommissioning operations (in the DECON and SAFSTOR scenarios).

The spent fuel in the wet storage pools at the cessation of plant operations is expected to be transferred to the ISFSI (DECON and SAFSTOR scenarios) within the first five and one-half years following shutdown. Once the wet storage pools are emptied, the reactor buildings can be either decontaminated and dismantled or prepared for long-term storage. The spent fuel pools are kept operational in the Delayed DECON scenario until the transfer of spent fuel from the pools to the DOE can be completed.

Exelons strongly held position is that the DOE has a contractual obligation to accept Oyster Creeks fuel in a timely manner and consistent with its contract commitments. No assumption made in this study should be interpreted to be inconsistent with this claim. However, at this time, including the cost of storing spent fuel in this study is the most reasonable approach because it insures the availability of sufficient TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 1, Page 7 of 9 decommissioning funds at the end of the stations life if the DOE has not met its contractual obligation to take the fuel.

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. With the passage of the Low-Level Radioactive Waste Policy Act in 1980,[14] and its Amendments of 1985,[15] the states became ultimately responsible for the disposition of low-level radioactive waste generated within their own borders.

New Jersey is a member of the three-state Atlantic Interstate Low-Level Radioactive Waste Management Compact, formed after South Carolina formally joined the Northeast Regional Compact. The Barnwell Low-Level Radioactive Waste Management Facility, located in South Carolina, is expected to be available to support the decommissioning of Oyster Creek. It is also assumed that Exelon can access other disposal sites, should it prove cost-effective. As such, rate schedules for both the Barnwell and the EnergySolutions facility in Clive, Utah are used to generate disposal costs.

For the purpose of this analysis, the EnergySolutions facility is used as the basis for estimating the disposal cost for the lowest level and majority of the radioactive waste (Class A [16]). EnergySolutions does not have a license to dispose of the more highly radioactive waste (Classes B and C), for example, generated in the dismantling of the reactor vessel.

The disposal cost for this material is based upon the rate schedule for the Barnwell facility.

The dismantling of the components residing closest to the reactor core generates radioactive waste considered unsuitable for shallow-land disposal (i.e., low-level radioactive waste with concentrations of radionuclides that exceed the limits established by the NRC for Class C radioactive waste (GTCC)). The Low-Level Radioactive Waste Policy Amendments Act of 1985 assigned the federal government the responsibility for the disposal of this material. The Act also stated that the beneficiaries of the activities resulting in the generation of such radioactive waste bear all reasonable costs of disposing of such waste.

However, to date, the federal government has not identified a cost for TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 1, Page 8 of 9 disposing of GTCC or a schedule for acceptance. As such, the GTCC radioactive waste in this study is assumed to be packaged and disposed of as high-level waste, at a cost equivalent to that envisioned for the spent fuel.

The GTCC material is either stored with the spent fuel at the ISFSI or shipped directly to a DOE facility as it is generated (depending upon the timing of the decommissioning and whether the spent fuel has been removed from the site prior to the start of decommissioning).

A significant portion of the waste material generated during decommissioning may only be potentially contaminated by radioactive materials. This waste can be analyzed 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 for Oyster Creek 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,[17] 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 Oyster Creek assume that the site will be remediated to a residual level consistent with the NRC-prescribed level as well as the State of New Jerseys remedial action levels for radioactive material.

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 TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 1, Page 9 of 9 Response, Compensation, and Liability Act (CERCLA or Superfund).[18]

An additional limit of 4 millirem per year, as defined in 40 CFR §141.16, is applied to drinking water.[19]

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)[20] 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 in the cleanup. As such, the possibility of dual regulation remains for certain licensees. The present study does not include any costs for this occurrence.

2. DECOMMISSIONING ALTERNATIVES Detailed cost estimates were developed to decommission Oyster Creek for three variations of the approved decommissioning alternatives: DECON and SAFSTOR.

Although the scenarios 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 station. The scenarios selected are representative of alternatives available to the owner and are defined as follows:

1. DECON: Decommissioning activities commence shortly after the cessation of plant operations. The spent fuel in the plants spent fuel storage pool is transferred to the ISFSI within five and one-half years. The equipment, structures, and portions of the plant containing radioactive contaminants are removed or decontaminated to a level that permits the facility to be released for unrestricted use. Non-essential structures are then demolished. Spent fuel storage operations continue at the site (ISFSI) until the transfer of the fuel to the DOE is complete, assumed to be in the year 2036.

2. Delayed DECON: In the second scenario the unit is shutdown and prepared for dismantling similar to the DECON scenario; however, in this scenario, the unit enters an abbreviated period of storage prior to the actual start of field activities. The spent fuel discharged to the storage pool once operations cease remains in the pool until it can be transferred to a DOE facility. The ISFSI, used to support operations, is not used to off-load the storage pool.

Decommissioning is delayed until the transfer of the fuel from both the pool and ISFSI to the DOE is completed in the year 2036. The unit is then decommissioned.

3. SAFSTOR: The unit is placed into safe-storage in the third scenario.

Decommissioning is deferred beyond the fuel storage period to the maximum extent possible; termination of the license would conclude within the required 60-year period. The spent fuel in the plants spent fuel storage pool is transferred to the ISFSI within five and one-half years. Spent fuel storage operations continue at the site until the transfer of the fuel to the DOE is complete, assumed to be in the year 2036. The plant remains in safe-storage following the removal of spent fuel from the site, timed to allow final decommissioning and license termination to be completed within 60 years of final shutdown. As with the first two scenarios, decommissioning activities are TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 2, Page 2 of 14 integrated so as to minimize the total duration of the physical dismantling process.

The following sections describe the basic activities associated with each alternative.

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 commences with the effective date of permanent cessation of operations and involves the transition of both plant and licensee from reactor operations (i.e., power production) to facilitate de-activation and closure. During the first phase, notification is to be provided to the NRC certifying the permanent cessation of operations and the removal of fuel from the reactor vessel. The licensee would then be prohibited from reactor operation.

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 Oyster Creek 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 DECON The DECON alternative, as defined by the NRC, is "the alternative in which the equipment, structures, and portions of a facility and site containing radioactive contaminants are removed or decontaminated to a level that permits the property to be released for unrestricted use shortly after cessation of operations." This study does not address the cost to dispose of the spent fuel residing at the site; such costs are funded through a surcharge on electrical generation. However, the study does estimate the costs incurred with the interim on-site storage of the fuel pending shipment by the DOE to an off-site disposal facility.

2.1.1 Period 1 - Preparations In anticipation of the cessation of plant operations, detailed preparations are undertaken to provide a smooth transition from plant operations to site decommissioning. Through implementation of a staffing transition plan, the organization required to manage the TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 2, Page 3 of 14 intended decommissioning activities is assembled from available plant staff and outside resources. Preparations include the planning for permanent defueling of the reactor, revision of technical specifications applicable to the operating conditions and requirements, a characterization of the facility and major components, and the development of the PSDAR.

Engineering and Planning The PSDAR, required before or within two years after permanent cessation of operations, provides a description of the licensees planned decommissioning activities, a timetable, and the associated financial requirements of the intended decommissioning program. Upon receipt of the PSDAR, the NRC will make the document available to the public for comment in a local meeting to be held in the vicinity of the reactor site.

Ninety days following submittal and NRC receipt of the PSDAR, the licensee may begin to perform major decommissioning activities under a modified 10 CFR §50.59 procedure, i.e., without specific NRC approval.

Major activities are defined as any activity that results in permanent removal of major radioactive components, permanently modifies the structure of the containment, or results in dismantling components (for shipment) containing GTCC, as defined by 10 CFR §61. Major components are further defined as comprising the reactor vessel and internals, large bore reactor recirculation system piping, and other large components that are radioactive. The NRC includes the following additional criteria for use of the §50.59 process in decommissioning. The proposed activity must not:

foreclose release of the site for possible unrestricted use, significantly increase decommissioning costs, cause any significant environmental impact, or violate the terms of the licensees existing license.

Existing operational technical specifications are reviewed and modified to reflect plant conditions and the safety concerns associated with permanent cessation of operations. The environmental impact associated with the planned decommissioning activities is also considered. Typically, a licensee will not be allowed to proceed if the consequences of a particular decommissioning activity are greater than that bounded by previously evaluated environmental assessments or impact statements. In this instance, the licensee would have to submit TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 2, Page 4 of 14 a license amendment for the specific activity and update the environmental report.

The decommissioning program outlined in the PSDAR 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 PSDAR, activity specifications, cost-benefit and safety analyses, and work packages and procedures, would be assembled to support the proposed decontamination and dismantling activities.

Site Preparations Following final plant shutdown, and in preparation for actual decommissioning activities, the following activities are initiated:

Characterization of the site and surrounding environs. This includes radiation surveys of work areas, major components (including the reactor vessel and its internals), internal piping, and primary shield cores.

Isolation of the spent fuel storage pool and fuel handling systems, such that decommissioning operations can commence on the balance of the plant. Decommissioning operations are scheduled around the fuel handling area to optimize the overall project schedule. The fuel is transferred to the ISFSI as it decays to the point that it meets the definition of standard fuel (DECON and SAFSTOR alternatives), or the DOE (Delayed DECON). Consequently, it is assumed that the fuel pool remains operational for approximately five and one-half years following the cessation of operations.

Specification of transport and disposal requirements for activated materials and/or hazardous materials, 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.

TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 2, Page 5 of 14 2.1.2 Period 2 - Decommissioning Operations This period includes the physical decommissioning activities associated with the removal and disposal of contaminated and activated components and structures, including the successful amendment of the 10 CFR §50 operating license (releasing the site, exclusive of the ISFSI).

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.

Reconfiguration and modification of site structures and facilities as needed to support decommissioning operations. This may include the upgrading of roads (on and off site) to facilitate hauling and transport. Modifications may be required to the containment structure to facilitate access of large/heavy equipment. Modifications may also be required to the refueling area of the reactor building to support the segmentation of the reactor vessel internals and component extraction.

Design and fabrication of temporary and permanent shielding to support removal and transportation activities, construction of contamination control envelopes, and the procurement of specialty tooling.

Procurement (lease or purchase) of shipping canisters, cask liners, and industrial packages.

Decontamination of components and piping systems as required to control (minimize) worker exposure.

Removal of piping and components no longer essential to support decommissioning operations.

Transfer of the steam separator and dryer assemblies to the dryer-separator pool for segmentation. Segmentation by weight and activity maximizes the loading of the shielded transport casks. The operations are conducted under water using remotely-operated tooling and contamination controls.

Disconnection of the control blades from the drives on the vessel lower head. Blades are transferred to the spent fuel pool for packaging.

Some of the material is expected to exceed Class C disposal requirements. As such, those segments are packaged in modified fuel storage canisters for geologic disposal.

Removal and segmentation of the remaining internals, fuel support castings, and core plate assembly.

Draining and decontamination of the reactor well and the permanent sealing of the spent fuel transfer gate. Installation of a shielded platform for segmentation of the reactor vessel. Cutting operations are performed in air using remotely operated equipment within a contamination control envelope, with the water level maintained just below the cut to minimize the working area dose rates. Sections are transferred to the dryer-separator pool for packaging and interim storage.

Disconnection of the control rod drives and instrumentation tubes from reactor vessel lower head. The lower reactor head and vessel support skirt are then segmented.

Removal of the reactor recirculation pumps. Exterior surfaces are decontaminated and openings covered. Components can serve as their own burial containers provided that all penetrations are properly sealed.

Demolition of the sacrificial shield activated concrete by controlled demolition.

At least two years prior to the anticipated date of license termination, an LTP is required. Submitted as a supplement to the Final Safety Analysis Report (FSAR) or its equivalent, the plan must include: a site characterization, description of the remaining dismantling activities, plans for site remediation, procedures for the final radiation survey, designation of the end use of the site, an updated cost estimate to complete the decommissioning, and any associated environmental concerns. The NRC will notice the receipt of the plan, make the plan available for public comment, and schedule a local meeting. LTP approval will be subject to any conditions and limitations as deemed appropriate by the Commission. The licensee may then commence with the final remediation of site facilities and services, including:

Removal of remaining plant systems and associated components as they become nonessential to the decommissioning program or worker TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 2, Page 7 of 14 health and safety (e.g., waste collection and treatment systems, electrical power and ventilation systems).

Removal of the steel liners from the drywell, disposing of the activated and contaminated sections as radioactive waste. Removal of any activated/contaminated concrete.

Removal of the steel liners from the steam separator and dryer pool, reactor well and spent fuel storage pool.

Surveys of the decontaminated areas of the containment structures.

Removal of the contaminated equipment and material from the turbine and radwaste buildings, and any other contaminated facility.

Use radiation and contamination control techniques until radiation surveys indicate that the structures 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 will facilitate surface decontamination and subsequent verification surveys required prior to obtaining release for demolition.

Removal of the remaining components, equipment, and plant services in support of the area release survey(s).

Routing of material removed in the decontamination and dismantling to a central processing area. Material certified to be free of contamination is released for unrestricted disposition, e.g., as scrap, recycle, or general disposal. 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).[21] This document incorporates the statistical approaches to survey design and data interpretation used by the EPA. It also identifies 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 TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 2, Page 8 of 14 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 the requested change to the operating license (that would release the property, exclusive of the ISFSI, for unrestricted use).

The NRC will amend the operating license if it determines that site remediation has been performed in accordance with the LTP, and that the terminal radiation survey and associated documentation demonstrate that the facility is suitable for release.

2.1.3 Period 3 - 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 structures.

Although performed in a controlled and safe manner, blasting, coring, drilling, scarification (surface removal), and the other decontamination activities will substantially degrade power block structures including the reactor, turbine and radwaste buildings. Under certain circumstances, verifying that subsurface radionuclide concentrations meet NRC site release requirements will require removal of grade slabs and lower floors, potentially weakening footings and structural supports.

This removal activity will be necessary for those facilities and plant areas where historical records, when available, indicate the potential for radionuclides having been present in the soil, where system failures have been recorded, or where it is required to confirm that subsurface process and drain lines were not breached over the operating life of the station.

Prompt dismantling of site structures is likely 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.

TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 2, Page 9 of 14 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.

2.1.4 ISFSI Operations and Decommissioning The ISFSI will continue to operate under a general license (10 CFR §50) following the amendment of the operating license to release the adjacent (power block) property. Assuming the DOE starts accepting fuel from Oyster Creek in 2034, transfer of spent fuel from the ISFSI is anticipated to continue through the year 2036.

At the conclusion of the spent fuel transfer process, the ISFSI will be decommissioned. The existing design for the ISFSI is based upon the use of a multi-purpose canister and a concrete horizontal module for pad storage. For purposes of this cost analysis, it is assumed that the concrete and steel in several of the modules will have low levels of neutron activation. These modules will be designated for controlled disposal. The remaining modules will be dismantled using conventional techniques for the demolition of reinforced concrete. The concrete storage pad will then be removed, and the area graded and landscaped to conform to the surrounding environment.

The NRC will terminate the §50 license when it determines that the remediation of the ISFSI has been performed in accordance with an ISFSI license termination plan and that the final radiation survey and associated documentation demonstrate that the facility is suitable for release. Once the requirements are satisfied, the NRC can terminate the license for the ISFSI.

TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 2, Page 10 of 14 2.2 SAFSTOR AND DELAYED DECOMMISSIONING The NRC defines SAFSTOR 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." The facility is left intact (during the dormancy period), with structures maintained in a sound condition. Systems not required to operate in support of the spent fuel pool or site surveillance and security are drained, de-energized, and secured. Minimal cleaning/removal of loose contamination and/or fixation and sealing of remaining contamination are performed. Access to contaminated areas is secured to provide controlled access for inspection and maintenance.

The engineering and planning requirements are similar to those for the DECON alternative, although a shorter time period is expected for these activities due to the more limited work scope. Site preparations are also similar to those for the DECON alternative. However, with the exception of the required radiation surveys and site characterizations, the mobilization and preparation of site facilities is less extensive.

The following discussion is appropriate for both the SAFSTOR and Delayed DECON scenarios, the primary differences being in the storage methods for the spent fuel and the length of the dormancy period. Spent fuel is continued to be stored in the wet storage pool for the Delayed DECON scenario until such time that the transfer to a DOE facility can be completed, i.e., the ISFSI is not used to offload the pool. Decommissioning operations are assumed to begin once the transfer is complete. By contrast, all of the fuel remaining in the storage pool after the minimum required cooling period is relocated to the ISFSI in the SAFSTOR scenario and the pool emptied. The nuclear unit remains in storage after fuel transfer operations are completed, with decommissioning operations initiated such that the license is terminated within the required 60-year time period. In both scenarios, the spent fuel is transferred from the ISFSI to the DOE between the years 2034 and 2036.

2.2.1 Period 1 - Preparations Preparations for long-term storage include the planning for permanent defueling of the reactor, revision of technical specifications appropriate to the operating conditions and requirements, a characterization of the facility and major components, and the development of the PSDAR.

TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 2, Page 11 of 14 The process of placing the plant in safe-storage includes, but is not limited to, the following activities:

Isolation of the spent fuel storage services and fuel handling systems located in the reactor building so that safe-storage operations may commence on the balance of the plant. This activity may be carried out by plant personnel in accordance with existing operating technical specifications. Activities are scheduled around the fuel handling systems to the greatest extent possible.

Draining and de-energizing of the non-contaminated systems not required to support continued site operations or maintenance.

Disposing of contaminated filter elements and resin beds not required for processing wastes from layup activities for future operations.

Draining of the reactor vessel, with the internals left in place and the vessel head secured.

Draining and de-energizing non-essential, contaminated systems with decontamination as required for future maintenance and inspection.

Preparing lighting and alarm systems whose continued use is required; de-energizing portions of fire protection, electric power, and HVAC systems whose continued use is not required.

Cleaning of the loose surface contamination from building access pathways.

Performing an interim radiation survey of plant, posting warning signs where appropriate.

Erecting physical barriers and/or securing all access to radioactive or contaminated areas, except as required for inspection and maintenance.

Installing security and surveillance monitoring equipment and relocating security fence around secured structures, as required.

2.2.2 Period 2 - Dormancy The second phase identified by the NRC in its rule addresses licensed activities during a storage period and is applicable to the dormancy phases of the deferred decommissioning alternatives. Dormancy activities include a 24-hour security force, preventive and corrective TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 2, Page 12 of 14 maintenance on security systems, area lighting, general building maintenance, heating and ventilation of buildings, routine radiological inspections of contaminated structures, maintenance of structural integrity, and a site environmental and radiation monitoring program.

Resident maintenance personnel perform equipment maintenance, inspection activities, routine services to maintain safe conditions, adequate lighting, heating, and ventilation, and periodic preventive maintenance on essential site services.

An environmental surveillance program is carried out during the dormancy period to ensure that releases of radioactive material to the environment are prevented and/or detected and controlled. Appropriate emergency procedures are established and initiated for potential releases that exceed prescribed limits. The environmental surveillance program constitutes an abbreviated version of the program in effect during normal plant operations.

Security during the dormancy period is conducted primarily to prevent unauthorized entry and to protect the public from the consequences of their own actions. The security fence, sensors, alarms, and other surveillance equipment provide security. Fire and radiation alarms are also monitored and maintained. While remote surveillance is an option, it does not offer the immediate response time of a physical presence.

The transfer of the spent fuel to a DOE facility continues during this period until complete.

After an optional period of storage (such that license terminations are accomplished within 60 years of final shutdown), it is required that the licensee submit applications to terminate the license, along with an LTP (described in Section 2.1.2), thereby initiating the third phase.

2.2.3 Periods 3 and 4 - Delayed Decommissioning Prior to the commencement of decommissioning operations, preparations are undertaken to reactivate site services and prepare for decommissioning. Preparations include engineering and planning, a detailed site characterization, and the assembly of a decommissioning management organization. Final planning for activities and the writing of activity specifications and detailed procedures are also initiated at this time.

TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 2, Page 13 of 14 Much of the work in developing a termination plan is relevant to the development of the detailed engineering plans and procedures. The activities associated with this phase and the follow-on decontamination and dismantling processes are detailed in Sections 2.1.1 and 2.1.2. The primary difference between the sequences anticipated for the DECON and deferred scenarios is the absence, in the latter, of any constraint on the availability of the fuel storage facilities located within the reactor building for decommissioning.

Variations in the length of the dormancy period are expected to have little effect upon the quantities of radioactive wastes generated from system and structure removal operations. Given the levels of radioactivity and spectrum of radionuclides expected from fifty years of plant operation, no plant process system identified as being contaminated upon final shutdown will become releasable due to the decay period alone, i.e., there is no significant reduction in the waste generated from the decommissioning activities. However, due to the lower activity levels, a greater percentage of the waste volume can be designated for off-site processing and recovery.

The delay in decommissioning also yields lower working area radiation levels. As such, the estimates for the delayed scenarios incorporate reduced ALARA controls for the lower occupational exposure potential.

Although the initial radiation levels due to 60Co will decrease during the dormancy period, the internal components of the reactor vessel will still exhibit sufficiently high radiation dose rates to require remote sectioning under water due to the presence of long-lived radionuclides such as 94Nb, 59Ni, and 63Ni. Therefore, the dismantling procedures described for the DECON alternative would still be employed during SAFSTOR scenario. Portions of the sacrificial shield will still be radioactive due to the presence of activated trace elements with long half-lives (152Eu and 154Eu). Decontamination will require controlled removal and disposal. It is assumed that radioactive corrosion products on inner surfaces of piping and components will not have decayed to levels that will permit unrestricted use or allow conventional removal.

These systems and components will be surveyed as they are removed and disposed of in accordance with the existing radioactive release criteria.

If the site structures are to be dismantled, dismantling as a continuation of the decommissioning process is clearly the most appropriate and cost-effective option, as described in Section 2.1.3. The basis for the dismantling cost in the SAFSTOR scenario is consistent with that described for DECON, presuming the removal of structures and site facilities to a nominal depth of three feet below grade and the limited restoration of the site.

3. COST ESTIMATE The cost estimates prepared for decommissioning Oyster Creek consider the unique features 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 were developed with site-specific, technical information developed in an evaluation prepared for Exelon in 2008-09. 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.

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,"[22] and the DOE "Decommissioning Handbook."[23] 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 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.[24]

This analysis reflects lessons learned from TLGs 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 TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 3, Page 2 of 21 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 WDFs were assigned to each area, commensurate with the inefficiencies associated with working in confined, hazardous environments. The ranges used for the WDFs are as follows:

Access Factor 0% to 50%

Respiratory Protection Factor 0% to 25%

Radiation/ALARA Factor 0% to 100%

Protective Clothing Factor 0% to 50%

Work Break Factor 8.33%

These factors and their associated range of values were developed in conjunction with the Atomic Industrial Forums Guideline Study. The factors (and their suggested application) are discussed in more detail in Appendix F.

Scheduling Program Durations The unit factors, adjusted by the WDFs as described above, are applied against the inventory of materials to be removed in the radiologically controlled areas.

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 area-by-area activity duration critical path was used to develop the total decommissioning program schedule. The unit cost factors, adjusted for WDFs as described above, were applied against the inventory of materials to be removed in each defined work area. Each work area was assessed for the most efficient number of workers/crews for the decommissioning activities. These TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 3, Page 3 of 21 adjusted unit cost factors were applied against the available manpower so that an overall duration for removal of components and piping from each work area could be calculated. Work area identification is consistent with the Survey Tracking Number (STN) system utilized by GPUs radiological services group in the 1997 timeframe. An index of the GPU STNs is provided in Appendix G.

The program schedule is used to determine the period-dependent costs for program management, administration, field engineering, equipment rental, contracted services, etc. The study relies upon regional or site-specific salary and wage rates for the personnel associated with the intended program.

3.3 FINANCIAL COMPONENTS OF THE COST MODEL TLGs 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.

3.3.1 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[25]

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." 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 TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 3, Page 4 of 21 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 remaining operating life of the station.

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, now highly radioactive after a lifetime of exposure to core activity. 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 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 TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 3, Page 5 of 21 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 TLGs 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%

Spent Fuel Storage (Dry) Modules 15%

Spent Fuel Transfer Costs 15%

Operations and Maintenance Expenses 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 TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 3, Page 6 of 21 reported for the DECON alternative is 18.3%. Values for the other alternatives are delineated within their respective detailed cost tables in Appendices D and E.

3.3.2 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:

Transition activities and costs: ancillary expenses associated with eliminating 50% to 80% of the site labor force shortly after the cessation of plant operations, added cost for worker separation packages throughout the decommissioning program, national or company-mandated retraining, and retention incentives for key personnel.

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, for example, in the start and rate of acceptance of spent fuel by the DOE).

Pricing changes for basic inputs, such as labor, energy, materials, and burial.

TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 3, Page 7 of 21 This cost study, however, does not add any additional cost to the estimate for financial risk since there is insufficient historical data from which to project future liabilities. Consequently, the areas of uncertainty or risk are revisited periodically and addressed through repeated revisions or updates of the base estimate.

3.4 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 impacts of the considerations identified below are included in this cost study.

3.4.1 Spent Fuel Management The cost to dispose of spent fuel generated from plant operations is not reflected within the estimates to decommission the Oyster Creek site.

Ultimate disposition of the spent fuel is within the province of the DOEs Waste Management System, as defined by the NWPA. As such, the disposal cost is financed by a 1 mill/kWhr surcharge paid into the DOEs waste fund during operations. However, the NRC requires licensees to establish a program to manage and provide funding for the management of all irradiated fuel at the reactors until title of the fuel is transferred to the Secretary of Energy. This funding requirement is fulfilled through inclusion of certain high-level waste cost elements within the estimate, as described below.

The total inventory of assemblies that will require handling during decommissioning is based upon several assumptions. The pickup of commercial fuel is assumed to begin in the year 2025. The maximum rate at which the fuel is removed from the commercial sites is based upon an annual capacity at the geologic repository of 3,000 metric tons of uranium (MTU). Any delay in the startup of the repository or decrease in the rate of acceptance will correspondingly prolong the transfer process and result in the fuel remaining at the site longer.

In all three scenarios, the existing ISFSI will continue to operate for the fifteen years following final shutdown. Assuming that the DOE commences repository operation in 2025, all fuel is projected to be removed from the Oyster Creek site by the year 2036.

TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 3, Page 8 of 21 Operation and maintenance costs for the storage facilities are included within the estimates and address the cost for staffing the facilities, as well as security, insurance, and licensing fees. Costs are also provided for the final disposition of the facilities once the transfer is complete.

Repository Startup Operation of the DOEs yet-to-be constructed geologic repository is contingent upon the review and approval of the facilitys license application by the NRC, the successful resolution of pending litigation, and the development of a national transportation system. With the appropriate authorizations from Congress, the Administration currently plans to implement a program over the next 10 years that could result in an interim storage facility being available by 2025.

Spent Fuel Management Model The Exelon nuclear fleet consists of 26 units at 14 sites in Illinois, Pennsylvania, New Jersey, New York and Maryland, including the inactive units at Dresden, Peach Bottom and Zion (Zion is still included in the spent fuel analysis model since the fuel transfer to DOE will be done as part of the Exelon allocation). The ability to complete the decommissioning of these units, particularly for the DECON and Delayed DECON alternatives, is highly dependent upon when the DOE is assumed to remove spent fuel from the sites.

The DOE's repository program assumes that spent fuel will be accepted for disposal from the nation's commercial nuclear plants in the order (the "queue") in which it was removed from service ("oldest fuel first"). A computer model developed by Exelon Nuclear was used to determine when the DOE would provide allocations in the queue for removal of spent fuel from the individual sites. Repository operations were based upon annual industry-wide receipt of 400 Metric Tons Heavy Metal (MTHM) in the first year of operation, a total of 3,800 MTHM in years 2 through 4 and 3,000 MTHM for year 5 and beyond.[26]

ISFSIs are constructed as necessary to maintain full-core discharge capability at the individual sites. Once the DOE begins repository operations, spent fuel shipments are managed across the fleet to optimize spent fuel storage.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 3, Page 9 of 21 Canister Design The design and capacity of future cask acquisitions for the ISFSI is based upon the NUHOMS system, with a 61-fuel assembly capacity.

The DOE is assumed to provide the MPC for fuel transferred directly from the pool to the DOE at no cost to the owner.

Canister Loading and Transfer The cost for the labor to load/transport the spent fuel from the pool to the ISFSI pad is based upon Exelon experience. For estimating purposes, 50% of this cost is used to estimate the cost to transfer the fuel from the ISFSI to the DOE.

Operations and Maintenance Annual costs (excluding labor) of approximately $763,000 and $90,000 are used for operation and maintenance of the spent fuel pool and the ISFSI, respectively.

ISFSI Design Considerations A multi-purpose (storage and transport) dry shielded storage canister with a horizontal, reinforced concrete storage module is used as a basis for the cost analysis. The final core off load, equivalent to 10 modules, is assumed to have some level of neutron-induced activation as a result of the long-term storage of the fuel (i.e., to levels exceeding free-release limits). The ten modules are disposed of at a licensed facility. The cost of the disposition of this material, as well as the demolition of the ISFSI facility, is included in the estimate.

3.4.2 Reactor Vessel and Internal Components The NSSS (reactor vessel and reactor recirculation system components) will be decontaminated using chemical agents prior to the start of cutting operations (for DECON alternative only). A decontamination factor (average reduction) of 10 is assumed for the process.

The reactor pressure vessel and internal components are segmented for disposal in shielded, reusable transportation casks. Segmentation is performed in the dryer-separator pool, where a turntable and remote cutter are installed. The vessel is segmented in place, using a mast-TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 3, Page 10 of 21 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.

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.[27] 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 equivalent to that envisioned for the spent fuel. It is not anticipated that the DOE would accept this waste prior to completing the transfer of spent fuel.

Therefore, until such time the DOE is ready to accept GTCC waste, it is reasonable to assume that this material would remain in storage at the Oyster Creek site.

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.

TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 3, Page 11 of 21 It is not known whether this option will be available when Oyster Creek ceases operation. Future viability of this option will depend upon the ultimate location of the disposal site, as well as the disposal site licensees ability to accept highly radioactive packages and effectively isolate them from the environment. Additionally, with BWRs, the diameter of the reactor vessel may severely limit overland transport.

Consequently, the study assumes the reactor vessel will require segmentation, as a bounding condition.

3.4.3 Primary System Components Reactor recirculation piping is cut from the reactor vessel once the water level in the vessel (used for personnel shielding during dismantling and cutting operations in and around the vessel) is dropped below the nozzle zone. The piping is boxed and transported by shielded van. The reactor recirculation pumps and motors are lifted out intact, packaged, and transported for processing and/or disposal.

3.4.4 Main Turbine and Condenser The main turbine will be dismantled using conventional maintenance procedures. The turbine rotors and shafts will be removed to a laydown area. The lower turbine casings will be removed from their anchors by controlled demolition. 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.

3.4.5 Transportation Methods Contaminated piping, components, and structural material other than the highly activated reactor vessel and internal components will qualify as LSA-I, II or III or Surface Contaminated Object, SCO-I or II, as described in Title 49.[28] 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. The reactor vessel and internal components are expected to be transported as Type B, in accordance with §71. It is conceivable that the reactor, due to its limited specific activity, could qualify as LSA-II or TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 3, Page 12 of 21 III. However, the high radiation levels on the outer surface would require that additional shielding be incorporated within the packaging so as to attenuate the dose to levels acceptable for transport.

Transport of the highly activated metal, produced in the segmentation of the reactor vessels and internal components, will be by shielded truck cask. Cask shipments may exceed 95,000 pounds, including vessel segment(s), 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) will be by a combination of truck, rail, and/or multi-wheeled transporter. Truck transport costs were estimated using published tariffs from Tri-State Motor Transit.[29]

3.4.6 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.

The mass of radioactive waste generated during the various decommissioning activities is reported by line item in Appendices C, D and E, and summarized in Section 5. The Section 5 waste summaries are consistent with 10 CFR §61 classifications. Commercially available steel containers are 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. The waste volumes are calculated on the exterior package dimensions for containerized material or a dimensional calculation for components serving as their own waste containers.

The more highly activated reactor components are transported in reusable, shielded truck casks with disposable liners. In calculating disposal costs, the burial fees are applied against the liner volume, with surcharges added for the special handling requirements and the TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 3, Page 13 of 21 radiological characteristics of the payload. Packaging efficiencies are lower for the highly activated materials (greater than Type A quantity waste), where high concentrations of gamma-emitting radionuclides limit the capacity of the shipping canisters.

Disposal fees are calculated using current disposal agreements, with surcharges added for the highly activated components, for example, generated in the segmentation of the reactor vessel. The majority of the material generated from the decontamination and dismantling activities (approximately 94% for the DECON alternative) is Class A waste. The disposal cost for this material is based upon Exelons current agreement with EnergySolutions for its disposal facility in Clive, Utah. Another 5%

of the total volume (also Class A) is assumed to be sent to the Barnwell facility.

Since the EnergySolutions facility is not able to accept the higher activity waste (Class B and C) generated in the decontamination of the reactor vessel and segmentation of the components closest to the core, the cost of disposal of this material (approximately 1% of the total volume) was based upon Exelons rates for the Barnwell facility.

Material exceeding Class C limits (limited to material closest to the reactor core and comprising less than 0.4% of the total waste volume) is generally not suitable for shallow-land disposal. This material is packaged in the same multipurpose canisters used for spent fuel storage/transport.

3.4.7 Site Conditions Following Decommissioning The NRC will terminate (or amend) the site license when it determines that site remediation has been performed in accordance with the license termination plan, and that the terminal radiation survey and associated documentation demonstrate that the facility is suitable for release. The NRCs 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 owners 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 TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 3, Page 14 of 21 regraded such that the power block area will have a final contour consistent with adjacent surroundings.

The estimates include the remediation of contaminated soil. This assumption may be affected by continued plant operations and/or future regulatory actions, such as the development of site-specific release criteria.

3.5 ASSUMPTIONS The following are the major assumptions made in the development of the estimates for decommissioning the site.

3.5.1 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.

3.5.2 Labor Costs The craft labor required to decontaminate and dismantle the nuclear unit 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 Exelon or from comparable industry information.

Exelon will hire a Decommissioning Operations Contractor (DOC) to manage the decommissioning. The owner will provide site security, radiological health and safety, quality assurance and overall site administration during the decommissioning and demolition phases.

Contract personnel will provide engineering services (e.g., for preparing the activity specifications, work procedures, activation, and structural analyses) under the direction of Exelon.

TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 3, Page 15 of 21 3.5.3 Design Conditions Any fuel cladding failure that occurred during the lifetime of the plant is assumed to have released fission products at sufficiently low levels that the buildup of quantities of long-lived isotopes (e.g., 137Cs, 90Sr, or transuranics) has been prevented from reaching levels exceeding those that permit the major NSSS components to be shipped under current transportation regulations and disposal requirements.

The curie contents of the vessel and internals at final shutdown are derived from those listed in NUREG/CR-3474.[30] Actual estimates are derived from the curie/gram values contained therein and adjusted for the different mass of the Oyster Creek components, projected operating life, and different periods of decay. Additional short-lived isotopes were derived from NUREG/CR-0130[31] and NUREG/CR-0672,[32] and benchmarked to the long-lived values from NUREG/CR-3474.

The disposal cost for the control blades removed from the vessel with the final core load is included within the estimates. Control blade residence time in the reactor is assumed to be controlled such that the blades do not become GTCC material. Disposition of any blades stored in the pool from operations is considered an operating expense and therefore not accounted for in the estimates.

Activation of the reactor building structure is confined to the sacrificial shield. More extensive activation (at very low levels) of the interior structures within containment has been detected at several reactors and their owners have elected to dispose of the affected material at a controlled facility rather than reuse the material as fill on site or send it to a landfill. The ultimate disposition of the material removed from the reactor building will depend upon the site release criteria selected, as well as the designated end use for the site.

3.5.4 General Transition Activities Existing warehouses will be cleared of non-essential material and remain for use by Exelon and its subcontractors. The plants operating staff will perform the following activities at no additional cost or credit to the project during the transition period:

TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 3, Page 16 of 21 Drain and collect fuel oils, lubricating oils, and transformer oils for recycle and/or sale.

Drain and collect acids, caustics, and other chemical stores for recycle and/or sale.

Processes operating waste inventories, i.e., the estimates do not address the disposition of any legacy wastes; the disposal of operating wastes during this initial period is not considered a decommissioning expense.

Scrap and Salvage The existing plant equipment is considered obsolete and suitable for scrap as deadweight quantities only. Exelon will make economically reasonable efforts to salvage equipment following final plant shutdown.

However, dismantling techniques assumed by TLG for equipment in this analysis are not consistent with removal techniques required for salvage (resale) of equipment. Experience has indicated that some buyers wanted equipment stripped down to very specific requirements before they would consider purchase. This required expensive rework after the equipment had been removed from its installed location. Since placing a salvage value on this machinery and equipment would be speculative, and the value would be small in comparison to the overall decommissioning expenses, this analysis does not attempt to quantify the possible salvage value that an owner may realize based upon those efforts.

It is assumed, for purposes of this analysis, that any value received from the sale of scrap generated in the dismantling process would be more than offset by the on-site processing costs. The dismantling techniques assumed in the decommissioning estimates do not include the additional cost for size reduction and preparation to meet furnace ready conditions. For example, the recovery of copper from electrical cabling may require the removal and disposition of any contaminated insulation, an added expense. With a volatile market, the potential profit margin in scrap recovery is highly speculative, regardless of the ability to free release this material. This assumption is an implicit recognition of scrap value in the disposal of clean metallic waste at no additional cost to the project.

Furniture, tools, mobile equipment such as forklifts, trucks, bulldozers, and other property will be removed at no cost or credit to the TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 3, Page 17 of 21 decommissioning project. Disposition may include relocation to other facilities. Spare parts will also be made available for alternative use.

Energy For estimating purposes, the plant is assumed to be de-energized, with the exception of those facilities associated with spent fuel storage.

Replacement power costs are used for the cost of energy consumption during decommissioning for tooling, lighting, ventilation, and essential services.

Insurance Costs for continuing coverage (nuclear liability and property insurance) following cessation of plant operations and during decommissioning are included and based upon current operating premiums. Reductions in premiums throughout the decommissioning process are based upon guidance provided by Exelon.

Taxes Property taxes are included for all decommissioning periods. Exelon provided a schedule estimate of decreasing tax payments against the current tax assessment. These reductions continue until reaching a minimum property tax payment of $1,000,000 per year; this level is maintained for the balance of the decommissioning program.

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.

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. In addition, the scheduling has been revised to reflect the spent fuel management plans described in Section 3.4.1.

A schedule or sequence of activities is presented in Figure 4.1 for the DECON decommissioning alternative. The schedule is also representative of the work activities identified in the delayed dismantling scenarios, absent any spent fuel constraints. The scheduling sequence assumes that fuel is removed from the spent fuel pool within the first five and one-half years after operations cease. 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 2010" computer software.[33]

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 DECON decommissioning schedule:

The reactor building is isolated until such time that all spent fuel has been discharged from the storage pool to the DOE. Decontamination and dismantling of the storage pool is initiated once the transfer of spent fuel to the DOE is complete.

All work (except vessel and internals removal) is performed during an 8-hour workday, 5 days per week, with no overtime. There are eleven paid holidays per year.

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 TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 4, Page 2 of 7 and laydown space, and with the stringent safety measures necessary during demolition of heavy components and structures.

For plant systems removal, the systems with the longest removal durations in areas on the critical path are considered to determine the duration of the activity.

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 Oyster Creek. 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. A second critical path is also shown for the spent fuel cooling period, which determines the release of the reactor building for final decontamination.

Project timelines are provided in Figures 4.2 through 4.4; the milestone dates are based on this same shutdown date. The start of decommissioning activities in the Delayed Decommissioning scenario is concurrent with the end of the fuel transfer activity (i.e., to an off-site DOE facility).

5. 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(s). This currently requires the remediation of all radioactive material at the site in excess of applicable legal limits. Under the Atomic Energy Act,[34] 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.

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 5.1 through 5.3. 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 and internals are categorized as large quantity shipments and, accordingly, will be shipped in reusable, shielded truck casks with disposable liners.

In calculating disposal costs, the burial fees are applied against the liner volume, as well as the special handling requirements of the payload. Packaging efficiencies are lower for the highly activated materials (greater than Type A quantity waste),

where high concentrations of gamma-emitting radionuclides limit the capacity of the shipping canisters.

No process system containing/handling radioactive substances at shutdown is presumed to meet material release criteria by decay alone, i.e., systems radioactive at shutdown will still be radioactive over the time period during which the decommissioning is accomplished, due to the presence of long-lived radionuclides.

TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002 Rev. 4 Decommissioning Cost Analysis Section 5, Page 2 of 5 While the dose rates decrease with time, radionuclides such as 137Cs will still control the disposition requirements.

The waste material generated in the decontamination and dismantling of Oyster Creek is primarily generated during Period 2 of the DECON alternative and Period 4 of the deferred alternatives. Material that is considered potentially contaminated when removed from the radiologically controlled area is sent to processing facilities in Tennessee for conditioning and disposal. Heavily contaminated components and activated materials are routed for controlled disposal. The disposal volumes reported in the tables reflect the savings resulting from reprocessing and recycling.

Disposal fees are calculated using current disposal agreements, with surcharges added for the highly activated components, for example, generated in the segmentation of the reactor vessel. The majority of the material generated from the decontamination and dismantling activities (approximately 94% for the DECON alternative) is Class A waste. The disposal cost for this material is based upon Exelons current agreement with EnergySolutions for its disposal facility in Clive, Utah. Another 5% of the total volume (also Class A) is assumed to be sent to the Barnwell facility.

Since the EnergySolutions facility is not able to accept the higher activity waste (Class B and C) generated in the decontamination of the reactor vessel and segmentation of the components closest to the core, the cost of disposal of this material (approximately 1% of the total volume) was based upon Exelons rates for the Barnwell facility.

A small quantity of material will be generated during the Oyster Creek decommissioning will not be considered suitable for near-surface disposal, and is assumed to be disposed of in a geologic repository, in a manner similar to that envisioned for spent fuel disposal. Such material, known as Greater-Than-Class-C or GTCC material, is estimated to require five spent fuel storage canisters (or the equivalent) to dispose of the most radioactive portions of the reactor vessel internals. The volume and weight reported in Tables 5.1 through 5.3 represent the packaged weight and volume of the spent fuel storage canisters.

6. RESULTS The analysis to estimate the costs to decommission Oyster Creek relied upon the site-specific, technical information developed for a previous analysis prepared in 2008-09. While not an engineering study, the estimates provide Exelon with sufficient information to assess their 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, low-level radioactive waste disposal practices, high-level radioactive waste management options, and site restoration requirements. The decommissioning scenarios assume continued operation of the plants spent fuel pool for a minimum of five and one-half years following the cessation of operations for continued cooling of the assemblies.

The spent fuel is removed from the site within fifteen years of final shutdown.

The cost projected to promptly decommission (DECON) Oyster Creek is estimated to be $899.7 million. The majority of this cost (approximately 74.0%) is associated with the physical decontamination and dismantling of the nuclear unit so that the license can be terminated. Another 19.7% is associated with the management, interim storage, and eventual transfer of the spent fuel. The remaining 6.3% is for the demolition of the designated structures and limited restoration of the site.

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 Exelon 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 operating license is terminated, the staff is substantially reduced for the conventional demolition and restoration of the site.

As described in this report, the spent fuel pool will remain operational for approximately five and one-half years following the cessation of operations (DECON alternative). The pool will be isolated and an independent spent fuel island created.

This will allow decommissioning operations to proceed in and around the pool area.

Within this approximately five and one-half-year period, the spent fuel will be transferred to the ISFSI.

TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 6, Page 2 of 6 The cost for waste disposal includes only those costs associated with the controlled disposition of the low-level 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 the majority of the radioactive material is at EnergySolutions facility in Clive, Utah or some alternative facility. Highly activated components, requiring additional isolation from the environment, are packaged for geologic disposal. Disposal of these components is based upon a cost equivalent for spent fuel.

A significant portion of the metallic waste is designated for additional processing and treatment at an off-site facility. Processing reduces the volume of material requiring controlled disposal through such techniques and processes as survey and sorting, decontamination, and volume reduction. The material that cannot be unconditionally released is packaged for controlled disposal at one of the currently operating facilities. The cost identified in the summary table for processing is all-inclusive, incorporating the ultimate disposition of the material.

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 labor cost data supplied by Exelon. 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 operating license. Prompt demolition reduces future liabilities and can be more cost effective than deferral, due to the deterioration of the facilities (and therefore the working conditions) with time.

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. For purposes of this analysis, material is primarily moved overland by truck.

Decontamination is used to reduce the plants radiation fields and minimize worker exposure. Slightly contaminated material or material located within a contaminated area is sent to an off-site processing center, i.e., this analysis does not assume that contaminated plant components and equipment can be decontaminated for uncontrolled release in-situ. Centralized processing centers have proven to be a TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Section 6, Page 3 of 6 more economical means of handling the large volumes of material produced in the dismantling of a nuclear unit.

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.

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. While site operating costs are greatly reduced following the final cessation of plant operations, certain administrative functions do need to be maintained either at a basic functional or regulatory level.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Appendix F, Page 1 of 12 APPENDIX F WORK DIFFICULTY FACTOR ADJUSTMENTS TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Appendix F, Page 2 of 12 GUIDELINES FOR APPLYING WORK DURATION ADJUSTMENT FACTORS TLG has historically applied work duration adjustment factors in determining unit cost factors to account for working in a radiologically controlled environment. In performing an area-by-area decommissioning estimate, the work duration factors are applied on an area basis based on the nominal area conditions. Where practical, areas are established based on similar working conditions.

The WDFs fall into five categories: access, respiratory protection, ALARA, protective clothing (PC), and work breaks. The guidelines of how these factors are assessed for each area is described below. Table F-1 details the WDFs used for each of the seven unit cost factor sets contained in the estimates. Table F-2 outlines the unit cost factors used for each area of the Oyster Creek plant.

1) Access Factor:

Controlling Variables:

Height of the component above the working floor Difficulty in working around the component (restricted access)

Source of Variable Information:

Estimators observation or judgment Plant drawings Range of Access Factor Adjustments:

0% - Components are accessible and located near a working level floor or platform 10% - Scaffolding (component less than <12 feet above floor) is required to access the majority of the components or the area around the components is congested.

20% - Scaffolding (component less than <12 feet above floor) is required to access the majority of the components and the area around the components is congested.

30% - Scaffolding (component between 12 - 20 feet above floor) is required to access the majority of the components or the area around the components are extremely congested.

TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Appendix F, Page 3 of 12 40% - Scaffolding (component between 20 - 45 feet above floor) is required to access the majority of the components).

50% - Scaffolding (component greater than 45 feet above floor) is required to access the majority of the components).

2) Respiratory Protection Factor:

Controlling Variables:

Component surface contamination levels (internal or external)

Type of work (potential to create an airborne problem)

General area surface contamination levels Site specific requirements for maintaining respirator qualifications (initial qualification, requalification, etc.)

Personal air sampler requirements Sources of Variable Information:

Radiation Work Permit Requirements Area Survey Maps Site Radiation Protection Program Manual Range of Respiratory Protection Factor Adjustments:

0% - Respiratory protection is not required (clean system or loose surface contamination has been removed).

25% - Respiratory protection is only required during limited segments of the work (i.e., physical cutting) 50% - Respiratory protection is continuously required while working on the component.

3) Radiation/ALARA Factor:

Controlling Variables:

Component contact dose rate General area dose rate Site specific requirements for maintaining radiation worker qualification (initial qualification, requalification, etc.)

Dosimetry requirements Sources of Variable Information:

Area Survey Maps Site Radiation Protection Program Manual Radiation Work Permit Requirements TLG Services, Inc.

Oyster Creek Nuclear Generating Station Document E16-1640-002, Rev. 4 Decommissioning Cost Analysis Appendix F, Page 4 of 12 Range of Radiation/ALARA Factor Adjustments:

(Note that surface contamination levels are principally accounted for in protective clothing requirements and respiratory protection requirements) 0% - The component is clean and is not located in a radiologically controlled area 10% - The component is located in a radiologically controlled area (General Area Radiation field < 2 .5 mrem/hr).

20% - The component is located in a radiologically controlled area (General Area Radiation field between 2. 5 to 15 mrem/hr).

40% - The component is located in a radiologically controlled area (General Area Radiation field between 16 and 99 mrem/hr).

100% - The component is located in a radiologically controlled area (General Area Radiation field > 100 mrem/hr).

4) Protective Clothing Factor:

Controlling Variables:

Component surface contamination levels (internal or external)

General area surface contamination levels Type of activity (wet/dry work, potential to create a surface contamination problem)

Site specific work schedule arrangements Sources of Variable Information:

Radiation Work Permit Requirements Area Survey Maps Site Radiation Protection Program Manual Range of Protective Clothing Factor Adjustments (alternate site-specific schedules may dictate alternate adjustments):

0% - The component is clean and is not located in a radiologically controlled area.

30% - The component is clean or contaminated and is located in a surface contamination controlled area. Work is to be completed in accordance with the requirements of an RWP, which specifies a single or double set of PCs, or PCs with plastics.

ATTACHMENT 2 SPENT FUEL MANAGEMENT PLAN FOR OYSTER CREEK NUCLEAR GENERATING STATION Spent Fuel Management Plan December 30, 2014 Page 1 of 3 ATTACHMENT 2 SPENT FUEL MANAGEMENT PLAN FOR OYSTER CREEK NUCLEAR GENERATING STATION

Background

Exelon Generation Company, LLC (Exelon) provided notice of its intention to permanently terminate operations at Oyster Creek Nuclear Generating Station (OCNGS) on December 31, 2019, pursuant to an Administrative Consent Order between Exelon and the New Jersey Department of Environmental Protection dated December 9, 2010.

A preliminary decommissioning cost estimate that evaluates three options for decommissioning OCNGS has been prepared. For the purpose of demonstrating the adequacy of funding to meet regulatory requirements, the SAFSTOR decommissioning option has been selected. This Spent Fuel Management Plan is similarly based on the SAFSTOR analysis, although the discussion below includes all three decommissioning options. Exelon has not made a final determination of the decommissioning approach for OCNGS. Exelon reserves the right to choose the ultimate decommissioning option in accordance with its business needs, recognizing that it needs to assure the chosen option meets U.S. Nuclear Regulatory Commission (NRC) requirements for decommissioning funding assurance.

There is an Independent Spent Fuel Storage Installation (ISFSI) on the OCNGS site operating under a NRC general license.

Spent Fuel Management Strategy The NRC requires (as discussed in 10 CFR 50.54(bb)) that licensees establish a program to manage and provide funding for the management of all irradiated fuel at the reactor following permanent cessation of operation of the reactor until title to the irradiated fuel and possession of the fuel is transferred to the Secretary of Energy for its ultimate disposal in a repository.

Pending transfer of the fuel to the U.S. Department of Energy (DOE), Exelon will store fuel on an interim basis in the storage pool and/or the ISFSI located at the OCNGS site.

A licensed ISFSI is currently operational at OCNGS. For the DECON and SAFSTOR scenarios, the ISFSI facility will be expanded to accommodate the inventory of spent fuel in the spent fuel pool at the conclusion of the required cooling period. Once the spent fuel pool is emptied of fuel, the reactor building can be either decontaminated and dismantled or prepared for long-term storage. In the delayed DECON scenario, the spent fuel pool and the existing ISFSI facility would remain operational and used for the interim storage of the fuel until such time as the DOE takes title and possession of the fuel. The balance of the facility will be placed in a SAFSTOR condition. In all three decommissioning scenarios, the existing ISFSI will continue to operate until such time of the transfer of spent fuel to the DOE is complete.

Assuming that the DOEs generator allocation/receipt schedules are based upon the oldest fuel receiving the highest priority and that the DOE begins removing spent fuel from commercial facilities in 2025 with an annual capacity of 3,000 metric tons of uranium, spent fuel is projected to remain at the OCNGS site for approximately 17 years after the termination of operations Spent Fuel Management Plan December 30, 2014 Page 2 of 3 (spent fuel is projected to be removed from the OCNGS site by the end of 2036). Any delay in transfer of fuel to DOE or decrease in the rate of acceptance will correspondingly prolong the transfer process and result in spent fuel remaining at the site longer than anticipated.

Operation and maintenance costs for the storage facilities (ISFSI and spent fuel pool) are reflected in the cost estimate and include the costs for staffing the facilities, maintenance of necessary operational requirements as well as security, insurance, and licensing fees. The estimate includes the costs to purchase, load, and transfer the fuel storage canisters to the ISFSI and to decommission the ISFSI for each decommissioning scenario.

A discussion of site-specific considerations for the management of spent fuel at OCNGS under each decommissioning scenario may be found in Section 3.4.1 of the Decommissioning Cost Estimate Report.

When OCNGS terminates operations in 2019, OCNGS will continue to comply with existing NRC licensing requirements, including the operation and maintenance of the systems and structures needed to support continued operation of the OCNGS spent fuel pool and ISFSI, as necessary, under the decommissioning scenario ultimately selected. In addition, OCNGS will also comply with applicable license termination requirements in accordance with 10 CFR 50.82, Termination of license, with respect to plant shutdown and post-shutdown activities, including seeking NRC approvals as appropriate for the continued storage of irradiated fuel until transfer of the fuel to the DOE is complete.

Cost Estimate and Funding For Spent Fuel Management Based on the SAFSTOR Decommissioning Option Annual costs for spent fuel management under the SAFSTOR scenario range from approximately $3.3 million to $26.9 million with a total cost of $188.5 million (2014 dollars).

As of November 30, 2014, the OCNGS decommissioning trust fund balance was $869.9 million.

At this time, there are no annual contributions to the fund and none are anticipated through the decommissioning period. To the extent that the trust fund balance exceeds costs required for radiological decommissioning, trust fund monies (subject to receipt of an exemption), in conjunction with EGC operating revenues, will be used to pay for spent fuel management costs.

An additional potential source of funding for OCNGS spent fuel management costs is the Settlement Agreement between Exelon and the DOE, under which the United States Government has agreed to reimburse Exelon for costs incurred attributable to DOEs failure to meet its contractual obligations for the transfer of spent fuel from OCNGS and other Exelon nuclear plants (Reference A).

NRC Approvals This Spent Fuel Management Plan contemplates potential withdrawals from the decommissioning trust for spent fuel management purposes. Prior to any such withdrawals, in accordance with 10 CFR 50.12, Specific exemptions, Exelon will make appropriate submittals seeking an exemption from the requirements of 10 CFR 50.82(a)(8)(i)(A) in order to use the decommissioning trust funds for spent fuel management expenses. Exelon will monitor the funding level of the decommissioning fund to ensure that spent fuel management withdrawals will not inhibit the ability of Exelon to complete radiological decommissioning.

Settlement Agreement between the U.S. Department of Energy and Exelon Generation Company, LLC (including Commonwealth Edison Company and AmerGen Energy Company), signed and executed August 5, 2004, as amended by the Addendum to the Settlement Agreement signed May 4, 2009.
