Conway Senior Vice President* Energy Supply & Chief Nuclear Officer 10 CFR 50.75 77 Beale Street Mail Code B32 San Francisco, CA 94105 415.973.3336 Internal: 223.3336 Fax: 415.973.2313 Alternate Address Diablo Canyon Power Plant p. O. Box 56 Avila Beach, CA 93424 805.545.3333 Fax: 805.545.4884 Decommissioning Funding Report for Diablo Canyon Power Plant Units 1 and 2 Dear Commissioners and Staff: PG&E is submitting the decommissioning fund report for Diablo Canyon Power Plant (DCPP) Units 1 and 2, pursuant to the requirements of 10 CFR 50.75(f). Diablo Canyon Units 1 and 2 At the end of calendar year 2010, the market value of the DCPP Units 1* (3411 MWt) and 2 (3411 MWt) decommissioning trust fund Market value was $807.5 million and $1,083.1 million respectively. Based on the site-specific decommissioning cost estimate prepared by TLG Services, Inc., and adjusted per the Nuclear Decommissioning Cost Triennial Proceeding (NDCTP) Decision 10-07-047 from the California Public Utilities Commission (CPUC), PG&E is confident that the DCPP Units 1 and 2 decommissioning trust fund balance in 2024 and 2025 will meet the minimum NRC decommissioning amount of $580.3 million (2011 dollars) for each unit that was calculated pursuant to the requirements specified in 10 CFR 50.75(c). Supporting Cost Estimates Based on site-specific cost estimates prepared by TLG Services, Inc. and the NDCTP Decision 10-07-047, PG&E has estimated that the decommissioning costs are approximately $583.9 million for DCPP Unit 1 and $546 million for Unit 2 in 2011 dollars. These costs do not include site restoration of the facilities ($258.6 million) nor spent fuel management costs after shutdown of the Units ($637.4 million). To assure that sufficient funds will be available for decommissioning, PG&E has established separate external sinking trust fund accounts for DCPP Units 1 and 2.

SUMMARY

Document POla1604-003, Rev. 0 Page vii of xvii This report presents estimates of the cost to decommission the Diablo Canyon Power Plant (Diablo Canyon) for the selected decommissioning scenarios following the scheduled cessation of plant operations. The analysis relies upon site-specific, technical information from an evaluation prepared in 2005,[1] updated to reflect current assumptions pertaining to the disposition of the nuclear plant and relevant industry experience in undertaking such projects. The current estimates are designed to provide Pacific Gas and Electric Company (PG&E), with sufficient information to assess the plant owners' financial obligations, as they pertain to the eventual decommissioning of the nuclear plant. The primary goal of the decommissioning is the removal and disposal of the contaminated systems and structures so that the plant's operating licenses can be terminated. The analysis recognizes that spent fuel will be stored at the site in the plant's storage pools and in an independent spent fuel storage installation (ISFSI) until such time that it can be transferred to the U.S. Department of Energy (DOE) federal repository. Consequently, the estimates also include those costs to manage and subsequently decommission these interim storage facilities. The currently projected cost to decommission the station, assuming the DECON alternative, is estimated at $1,828.3 million, as reported in 2008 dollars. An estimate for the SAFSTOR alternative is also provided. The estimates 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 estimates incorporate a minimum cooling period of approximately 12 years for the spent fuel that resides in the storage pools when operations cease.l 2] In both scenarios that were analyzed, any residual fuel remaining in the pools after the 12-year period is relocated to the ISFSI to await transfer to a DOE facility. The estimates also include the dismantling of site structures and non-essential facilities and the limited restoration of the site. "Decommissioning Cost Analysis for the Diablo Canyon Power Plant," Document No. POl-1513-004, Rev. 0, TLG Services, Inc., June 2005 2 The current Part 72 ISFSI license does not allow dry cask storage of spent fuel with burnups above 45,000 MWD/metric ton. It is assumed that PG&E can amend the Part 72 license to store the higher burnup fuel, but that as a condition of the amendment it will require longer decay times (12 years) before storing the spent fuel in the casks. TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Alternatives and Regulations Document POl-1604-003, Rev. 0 Page viii of xvii The ultimate objective of the decommissioning process is to reduce the inventory of contaminated and activated material so that the license can be terminated. The Nuclear Regulatory Commission (NRC or Commission) provided initial decommissioning requirements in its rule adopted on June 27, 1988)3] In this rule, the NRC set forth financial criteria for decommissioning licensed nuclear power facilities. The regulations addressed planning needs, timing, funding methods, and environmental review requirements for decommissioning. The rule also defined three decommissioning alternatives as being acceptable to the NRC: DECON, SAFSTOR, and ENTOMB. DECON is defined as "the alternative in which the equipment, structures, and portions of a facility and site containing radioactive contaminants are removed or decontaminated to a level that permits the property to be released for unrestricted use shortly after cessation of operations. "[4] SAFSTOR is defined as "the alternative in which the nuclear facility is placed and maintained in a condition that allows the nuclear facility to be safely stored and subsequently decontaminated (deferred decontamination) to levels that permit release for unrestricted use."[5] 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."[6] 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 3 U.s.

Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Page ix of xvii 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, rule making has been deferred pending the completion of additional research studies, for example, on engineered barriers. In 1996, the NRC published reVISIons to the general requirements for decommissioning nuclear power plants to clarify ambiguities and codify procedures and terminology as a means of enhancing efficiency and uniformity in the decommissioning processJ7] The amendments allow for greater public participation and better define the transition process from operations to decommissioning. Regulatory Guide 1.184, issued in July 2000, further described the methods and procedures acceptable to the NRC staff for implementing the requirements of the 1996 revised rule relating to the initial activities and major phases of the decommissioning process. The costs and schedules presented in this analysis follow the general guidance and processes described in the amended regulations. The format and content of the estimates is also consistent with the recommendations of Regulatory Guide 1.202, issued in February 2005.£8] Decommissioning Scenarios Two decommissioning scenarios are evaluated for the two nuclear units. The scenarios selected are representative of alternatives available to the owner and are defined as follows: DECON: The operating licenses for Units 1 and 2 currently expire in November 2024 and August 2025, respectively. The first scenario assumes that decommissioning activities at the two units are sequenced and integrated so as to minimize the total duration of the physical dismantling processes. Any residual spent fuel is transferred to the ISFSI to facilitate decontamination and dismantling activities within the fuel handling building. 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 2051. SAFSTOR: The units are placed into safe-storage in the second scenario. Spent fuel remaining in the spent fuel storage pools after a minimum cooling period of 12 years is transferred to the ISFSI for interim storage.

Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Page x of xvii SAFSTOR dormancy is established to schedule the beginning of Unit 1 decommissioning activities with the final spent fuel shipment from the ISFSI. As with the DECON scenario, decommissioning activities at the two units are sequenced and integrated so as to minimize the total duration of the physical dismantling processes. 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 incorporates site-specific costs and the latest available information on worker productivity in decommissioning. The estimates also reflect lessons learned from TLG's involvement in the Shippingport Station decommissioning, completed in 1989, and 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, Connecticut Yankee and San Onofre-1 nuclear units have provided additional insight into the process, the regulatory aspects, and technical challenges of decommissioning commercial nuclear units. 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. Contingency Consistent with cost estimating practice, contingencies are applied to the decontamination and dismantling costs developed as "specific provision for unforeseeable elements of cost within the defined project scope, particularly important where previous experience relating estimates and actual costs has shown that unforeseeable events which will increase costs are likely to occur." [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 9 T.S. LaGuardia et al., "Guidelines for Producing Commercial Nuclear Power Plant Decommissioning Cost Estimates," AIFINESP-036, May 1986 10 Project and Cost Engineers' Handbook, Second Edition, American Association of Cost Engineers, Marcel Dekker, Inc., New York, New York, p. 239. TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-l 604-003, Rev. 0 Page xi of xvii line-item basis. This contingency factor is a nearly universal element in all large-scale construction and demolition projects. It should be noted that contingency, as used in this analysis, is based on a preliminary technical position [11] to reflect the California Public Utilities Commission's desire for owners to conservatively establish an appropriate contingency factor for inclusion in the decommissioning revenue requirements. Contingency funds are expected to be fully expended throughout the program. As such, 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 [12] With the passage of the "Low-Level Radioactive Waste Policy Act" in 1980, [13] and its Amendments of 1985, [14] the states became ultimately responsible for the disposition of low-level radioactive waste (LLRW) generated within their own borders. Until recently, there were two facilities available to PG&E for the disposal of low-level radioactive waste generated by Diablo Canyon. As of July 1, 2008, however, the facility in Barnwell, South Carolina was closed to generators outside the Atlantic Compact (comprised of the states of Connecticut, New Jersey and South Carolina). This leaves the facility in Clive, Utah, operated by EnergySolutions, as the only available destination for low-level radioactive waste requiring controlled disposaL For the purpose of this analysis, the EnergySolutions' facility is used as the disposal site for the majority of the radioactive waste (Class A). There are no currently operating disposal facilities available to PG&E that 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 As such, waste disposal costs and waste transportation distances must be estimated. The disposal cost and transportation distance for low -level radioactive waste is based on a study sponsored by PG&E and Southern California Edison Company, "Establishing an Appropriate Disposal Rate for 11 "Technical Position Paper for Establishing an Appropriate Contingency Factor for Inclusion in the Decommissioning Revenue Requirements", Study Number: DECON-POS-H002, Revision A, Status: Preliminary (provided by PG&E). 12 U.S. Code of Federal Regulations, Title 10, Part 61, "Licensing Requirements for Land Disposal of Radioactive Waste" 13 "Low-Level Radioactive Waste Policy Act of 1980," Public Law 96-573, 1980. 14 "Low-Level Radioactive Waste Policy Amendments Act of 1985," Public Law 99-240, 1986. TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Page xii of xvii Low Level Radioactive Waste During Decommissioning." [15] The study was done to reflect the California Public Utilities Commission's desire for these owners to conservatively estimate their nuclear decommissioning LLRW disposal rates. 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 disposing of GTCC or a schedule for acceptance. As such, the GTCC radioactive waste has been packaged and disposed of as high-level waste, at a cost equivalent to that envisioned for the spent fuel. For purposes of this study, GTCC is packaged in the same type of canister used for 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 Diablo Canyon reflect the savings from waste recovery/volume reduction. High-Level Radioactive Waste Management Congress passed the "Nuclear Waste Policy Act" [16] (NWPA) in 1982, assigning the federal government's long-standing responsibility for disposal of the spent nuclear fuel created by the commercial nuclear generating plants to the DOE. The NWP A provided that DOE would enter into contracts with utilities in which DOE would promise to take the utilities' spent fuel and high-level radioactive waste and utilities would pay 15 "Establishing an Appropriate Disposal Rate for Low Level Radioactive Waste During Decommissioning", Robert A Snyder NEWEX, Revision 0, July 2008 (provided by PG&E). 16 "Nuclear Waste Policy Act of 1982 and Amendments," DOE's Office of Civilian Radioactive 1982 TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Page xiii of xvii the cost of the disposition services for that material. The NWP A, along with the individual contracts with the utilities, specified that the DOE was to begin accepting spent fuel by January 31, 1998. Since the original legislation, the DOE has announced several delays in the program schedule. By January 1998, the DOE had failed to accept any spent fuel or high level waste, as required by the NWP A and utility contracts. Delays continue and, as a result, generators have initiated legal action against the DOE in an attempt to obtain compensation for DOE's breach of contract. Operation of DOE's yet-to-be constructed repository is contingent upon the review and approval of the facility's license application by the NRC and the successful resolution of pending litigation. The DOE submitted its license application to the NRC on June 3, 2008, seeking authorization to construct the repository at Yucca Mountain, Nevada. Assuming a timely review and adequate funding, the DOE expects that receipt of fuel could begin as early as 2020. [17] It is generally necessary that spent fuel be cooled and stored for a minimum period at the generating site prior to transfer. As such, the NRC requires that licensees establish a program to manage and provide funding for the management of all irradiated fuel at the reactor site until title of the fuel is transferred to the Secretary of Energy, pursuant to 10 CFR Part 50.54(bb)J18] This funding requirement is fulfilled through inclusion of certain cost elements in the decommissioning estimates, for example, associated with the isolation and continued operation of the spent fuel pools and the ISFSI. The DOE's generator allocation/receipt schedules are based upon the oldest fuel receiving the highest priority. For purposes of this analysis, acceptance of commercial spent fuel by the DOE is expected to begin in 2020. The first assemblies removed from the Diablo Canyon site are assumed to be in 2028. With an estimated, maximum rate of transfer of 3,000 metric tons of uranium (MTU)/year, completion of the removal of fuel from the site is projected to be in the year 2051 . . Consequently, costs are included within the estimates for the long-term caretaking of the spent fuel at the Diablo Canyon site until the year 2051. An ISFSI, which is independently licensed and operated, will remain operational after the cessation of plant operations. For the DECON and SAFSTOR scenarios, the facility is expanded to accommodate the inventory of spent fuel residing in the plant's storage pools at the conclusion of the required cooling period. Once emptied, 17 DOE-RW-0604, "Project Decision Schedule", U.s.

TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document P01 5 1604-003, Rev. 0 Page xiv of xvii the spent fuel pool facilities can be either decontaminated and dismantled or prepared for long-term storage. Site Restoration The efficient removal of the contaminated materials at the site may result in damage to many of the site structures. Blasting, coring, drilling, and the other decontamination activities will substantially damage power block structures, potentially weakening the footings and structural supports. Prompt dismantling of site structures (once the facilities are decontaminated) is clearly the most appropriate and cost-effective option. It is unreasonable to anticipate that these structures would be repaired and preserved after the radiological contamination is removed. The cost to dismantle site structures with a work force already mobilized on site is more efficient than if the process is deferred. Site facilities quickly degrade without maintenance, adding additional expense and creating potential hazards to the public and the demolition work force. Consequently, this study assumes that site structures are removed to a nominal depth of three feet below the local grade level wherever possible. The site is then to be graded and stabilized. Summary The costs to decommission Diablo Canyon assumes the removal of all contaminated and activated plant components and structural materials such that the owner may then have unrestricted use of the site with no further requirements for an operating license. Low-level radioactive waste, other than GTCC waste, is sent to a commercial processor for treatment/conditioning or to a controlled disposal facility. Decommissioning 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 is complete. Once emptied, the storage facilities are also decommissioned. Both the DECON and SAFSTOR scenarIOS are described in Section 2. The assumptions are presented in Section 3, along with schedules of annual expenditures. The major cost contributors are identified in Section 6, with detailed activity costs, waste volumes, and associated manpower requirements delineated in Appendices C and D. The major cost components are also identified in the cost summary provided at the end of this section. The cost elements in the estimates are assigned to one of three subcategories: NRC License Termination, Spent Fuel Management, and Site Restoration. The subcategory "NRC License Termination" is used to accumulate costs that are consistent with "decommissioning" as defined by the NRC in its financial assurance regulations (i.e., TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Page xv of xvii 10 CFR Part 50.75). The cost reported for this subcategory is generally sufficient to terminate the unit's operating license, recognizing that there may be some additional cost impact from spent fuel management. The "Spent Fuel Management" subcategory contains costs associated with the containerization and transfer of spent fuel from the wet storage pools to a DOE transport cask, as well as the transfer of the fuel in storage at the ISFSI to the DOE. Costs are included for the operation of the storage pools and the management of the ISFSI until such time that the transfer is complete. "Site Restoration" is used to capture costs associated with the dismantling and demolition of buildings and facilities demonstrated to be free from contamination. This includes structures never exposed to radioactive materials, as well as those facilities that have been decontaminated to appropriate levels. Structures are removed to a depth of three feet and backfilled to conform to local grade. It should be noted that the costs assigned to these subcategories are allocations. Delegation of cost elements is for the purposes of comparison (e.g., with NRC financial guidelines) or to permit specific financial treatment (e.g., ARO determinations). In reality, there can be considerable interaction between the activities in the three subcategories. For example, an owner may decide to remove non-contaminated structures early in the project to improve access to highly contaminated facilities or plant components. In these instances, the non-contaminated removal costs could be reassigned from Site Restoration to an NRC License Termination support activity. However, in general, the allocations represent a reasonable accounting of those costs that can be expected to be incurred for the specific subcomponents of the total estimated program cost, if executed as described. As noted within this document, the estimates were developed and costs are presented in 2008 dollars. As such, the estimates do not reflect the escalation of costs (due to inflationary and market forces) over the remaining operating life of the plant or during the decommissioning period.

INTRODUCTION Document P01-1604-003, Rev. 0 Section 1, Page 1 of 8 This report presents estimates of the costs to decommission the Diablo Canyon Power Plant, (Diablo Canyon) following a scheduled cessation of plant operations. The analysis relies upon site-specific, technical information from an earlier evaluation prepared in 2005,[1]* updated to reflect current assumptions pertaining to the disposition of the nuclear plant and relevant industry experience in undertaking such projects. The current estimates are designed to provide Pacific Gas and Electric Company (pG&E) with sufficient information to assess the plant owners' financial obligations, as they pertain to the eventual decommissioning of the nuclear station. 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 costs to decommission Diablo Canyon, to provide a sequence or schedule for the associated activities, and to develop waste stream projections from the decontamination and dismantling activities. For the purposes of this study, the shutdown dates were taken as 40 years after receiving full power-operating licenses, or 2 November 2024 for Unit 1, and 26 August 2025 for Unit 2. 1.2 SITE DESCRIPTION Diablo Canyon is located on the central California coast in San Luis Obispo County, approximately 12 miles west southwest of the City of San Luis Obispo. The plant, comprised of two nuclear units, is located on a 750-acre site adjacent to the Pacific Ocean, roughly equidistant from San Francisco and Los Angeles. The Nuclear Steam Supply System (NSSS) consists of a pressurized water reactor and a four-loop Reactor Coolant System. The systems were supplied by the Westinghouse Electric Corporation. Units 1 and 2 each have a current license rating of 3411 MWt, with corresponding estimated ultimate net electrical outputs 1131 and 1156 megawatts (electric), respectively, with the reactors at rated power. The Reactor Coolant System is comprised of the reactor vessel and four heat transfer loops, each containing a vertical U-tube type steam generator, and a single-stage centrifugal reactor coolant pump. In addition, the system includes

Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Section 1, Page 2 of 8 an electrically heated pressurizer, a pressurizer relief tank, and interconnected piping. The system is housed within a "containment structure," a seismic Category I reinforced-concrete dry structure. It consists of an upright cylinder topped with a hemispherical dome, supported on a reinforced concrete foundation mat, which is keyed into the bedrock. A welded steel liner plate anchored to the inside face of the containment serves as a leak -tight membrane. The liner on top of the foundation mat is protected by a two-foot thick concrete fill mat, which supports the containment internals and forms the floor of the containment. The lower portion of the containment cylindrical wall has additional embedded wide flange steel beams between elevations 88 ft. 2 in. and 108 ft. 2 in. (mean sea level). Heat produced in the reactor is converted to electrical energy by the Steam and Power Conversion Systems. A turbine-generator system converts the thermal energy of steam produced in the steam generators into mechanical shaft power and then into electrical energy. The plant's turbine-generators are each tandem compound, four element units. They consist of one high-pressure double-flow and three low-pressure double-flow elements driving a coupled generator at 1800 rpm. The turbines are operated in a closed feedwater cycle that condenses the steam; the heated feedwater is returned to the steam generators. Heat rejected in the main condensers is removed by the Circulating Water System (CWS). The circulating water system provides the heat sink required for removal of waste heat in the power plant's thermal cycle. The system has the principal function of removing heat by absorbing this energy in the main condenser. Condenser circulating water is water from the Pacific Ocean. Each unit is served by two circulating water pumps at the intake structure. From this structure seawater is pumped through two circulating water conduits to the condenser inlet water boxes. The water is returned to the ocean at Diablo Cove through an outfall at the water's edge. 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 TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document P01-1604-003, Rev. 0 Section 1, Page 3 of 8 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. 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 plant's systems, structures and facilities are removed or decontaminated to levels that permit the site to be released for unrestricted use shortly after the cessation of plant operations. The rule also placed limits on the time allowed to complete the decommissioning process. For SAFSTOR, the process is restricted in overall duration to 60 years, unless it can be shown that a longer duration is necessary to protect public health and safety. The guidelines for ENTOMB are similar, providing the NRC with both sufficient leverage and flexibility to ensure that these deferred options are only used in situations where it is reasonable and consistent with the definition of 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 rule making permitting the controlled release of a site,[4] the NRC has re-evaluated this alternative. 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 rule making 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 entombmentsJ5] However, the NRC's 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 NRC's current priorities, at least until after the additional research studies are complete. The Commission concurred with the staffs recommendation. In 1996, the NRC published reVISIons to the general requirements for decommissioning nuclear power plantsJ6] When the decommissioning TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Section 1, Page 4 of 8 regulations were adopted in 1988, it was assumed that the majority of licensees would decommission at the end of the facility's 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 ambiguities and codify procedures and terminology as a means of enhancing efficiency and uniformity in the decommissioning process. The 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 an application to the NRC to terminate the license, wh,ich will include a license termination plan (LTP). 1.3.1 Nuclear Waste Policy Act Congress passed the "Nuclear Waste Policy Act" [7] (NWPA) in 1982, assigning the federal government's long-standing responsibility for disposal of the spent nuclear fuel created by the commercial nuclear generating plants to the DOE. The NWPA provided that DOE would enter into contracts with utilities in which DOE would promise to take the utilities' spent fuel and high-level radioactive waste and utilities would pay the cost of the disposition services for that material. The NWP A, along with the individual contracts with the utilities, specified that the DOE was to begin accepting spent fuel by January 31, 1998. Since the original legislation, the DOE has announced several delays in the program schedule. By January 1998, the DOE had failed to accept any spent fuel or high level waste, as required by the NWP A and utility contracts. Delays continue and, as a result, generators have initiated legal action against the DOE in an attempt to obtain compensation for DOE's breach of contract. TLG Services, Inc.

The DOE submitted its license application to the NRC on June 3, 2008, seeking authorization to construct the repository at Yucca Mountain, Nevada. Assuming a timely review and adequate funding, the DOE expects that receipt of fuel could begin as early as 2020. [8] I t is generally necessary that spent fuel be actively cooled and stored for a minimum period at the generating site prior to transfer. As such, the NRC requires that licensees establish a program to manage and provide funding for the management of all irradiated fuel at the reactor site until title of the fuel is transferred to the Secretary of Energy, pursuant to 10 CFR Part 50.54(bb). [9] This funding requirement is fulfilled through inclusion of certain cost elements in the decommissioning estimate, for example, associated with the isolation and continued operation of the spent fuel pools and ISFSI. DOE's contracts with utilities order the acceptance of spent fuel from utilities based upon the oldest fuel receiving the highest priority. For purposes of this analysis, acceptance of commercial spent fuel by the DOE is expected to begin in 2020 (in accordance with DOE's latest published schedule). The first assemblies removed from the Diablo Canyon site are assumed to be in 2028. With an estimated maximum rate of transfer of 3,000 metric tons of uranium (MTU)/year from the commercial generators, completion of the removal of fuel from the Diablo Canyon site is projected to be in the year 2051. Consequently, costs are included within the estimates for the long-term caretaking of the spent fuel at the Diablo Canyon site until the year 2051. An ISFSI, which is independently licensed and operated, will remain operational after the cessation of plant operations. For the DECON and SAFSTOR scenarios, the facility is expanded to accommodate the inventory of spent fuel residing in the plant's storage pools at the conclusion of the required cooling period. Once emptied, the spent fuel pool facilities can be either decontaminated and dismantled or prepared for long-term storage. 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, [10] although not all of the TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document P01-1604-003, Rev. 0 Section 1, Page 6 of 8 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. Until recently, there were two facilities available to PG&E for the disposal of low-level radioactive waste generated by Diablo Canyon. As of July 1, 2008, however, the facility in Barnwell, South Carolina was closed to generators outside the Atlantic Compact (comprised of the states of Connecticut, New Jersey and South Carolina). This leaves the facility in Clive, Utah, operated by EnergySolutions, as the only available destination for low-level radioactive waste requiring controlled disposaL For the purpose of this analysis, the EnergySolutions' facility is used as the disposal site for the majority of the radioactive waste (Class A). There are no currently operating disposal facilities available to PG&E that 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 As such, waste disposal costs must be estimated. The disposal cost for low-level radioactive waste is based on a study sponsored by PG&E and Southern California Edison Company, "Establishing an Appropriate Disposal Rate for Low Level Radioactive Waste During Decommissioning." [13] The study was done to reflect the California Public Utilities Commission's desire for these owners to conservatively estimate their nuclear decommissioning LLRW disposal rates. 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>>.

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 has been packaged and disposed of as high-level waste, at a cost equivalent to that envisioned for the spent fueL TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document P01-1604-003, Rev. 0 Section 1, Page 7 of 8 For purposes of this study, GTCC is packaged in the same type of canister used for spent fuel. The GTCCmaterial is either stored with the spent fuel 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 Diablo Canyon 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," [14] amending 10 CFR Part 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 assume that the Diablo Canyon site will be remediated to a residual level consistent with the NRC-prescribed level. It should be noted that the NRC and the Environmental Protection Agency (EPA) differ on the amount of residual radioactivity considered acceptable in site remediation. The EPA has two limits that apply to radioactive materials. An EPA limit of 15 millirem per year is derived from criteria established by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund). [15] An additional and separate limit of 4 millirem per year, as defined in 40 CFR §141.16, is applied to drinking water. [16] TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document P01-1604-003, Rev. 0 Section 1, Page 8 of 8 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 (MOD) [17] provides that EPA will defer exercise of authority under CERCLA for the majority of facilities decommissioned under NRC authority. The MOD 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 MOD. The MOD 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 MOD 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. TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document P01-1604-003, Rev. 0 Section 2, Page 1 of 13 2. DECOMMISSIONING ALTERNATIVES Detailed cost estimates were developed to decommission the Diablo Canyon nuclear plant for the following approved decommissioning alternatives: DECON and SAFSTOR. Although the alternatives differ with respect to technique, process, cost, and schedule, they attain the same result: the ultimate release of the site for unrestricted use. Two decommissioning scenarios were evaluated for the two nuclear units. The scenarios selected are representative of alternatives available to the owner and are defined as follows: DECON: Units 1 and 2 are currently expected to cease operations in November 2024 and August 2025, respectively. Spent fuel remaining in the spent fuel storage pools after a minimum cooling period of 12 years is transferred to the ISFSI for interim storage. This scenario assumes that decommissioning activities at the two units are sequenced and integrated so as to minimize the total duration of the physical dismantling processes. Any residual spent fuel is transferred to the ISFSI so as to facilitate decontamination and dismantling activities within the fuel handing building. 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 2051. SAFSTOR: The units are placed into safe-storage in this scenario. The start of field decommissioning is deferred to the end of the fuel storage period. Spent fuel remaining in the spent fuel storage pools after a minimum cooling period of 12 years is transferred to the ISFSI for interim storage. As with the DECON scenario, decommissioning activities at the two units are sequenced and integrated so as to minimize the total duration of the physical dismantling processes. 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 2051. 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 facility de-activation and closure. During the first phase, notification is to be provided to the NRC TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POI-1604-003, Rev. 0 Section 2, Page 2 of 13 certifying the permanent cessation of operations and the removal of fuel from the reactor vesseL The licensee is then 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 Diablo Canyon 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 intended decommissioning activities is assembled from available plant staff and outside resources. Preparations include the planning for permanent de fueling 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 within two years of the notice to cease operations, provides a description of the licensee's 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 hearing to be held in the vicinity of the reactor site. Ninety days TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POI-1604-003, Rev. 0 Section 2, Page 3 of 13 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 coolant 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 licensee's 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 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, work packages and procedures, would be assembled to support the proposed decontamination and dismantling activities. TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Site Preparations Document P01-1604-003, Rev. 0 Section 2, Page 4 of 13 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 pools and fuel handling systems, such that decommissioning operations can commence on the balance of the plant. The pools will remain operational for approximately twelve years following the cessation of operations before the inventory resident at shutdown can be transferred to the DOE. 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 metallic components generated in decommissioning), site security and emergency programs, and industrial safety. 2.1.2 Period 2 -Decommissioning Operations This period includes the wet spent fuel storage and physical decommissioning activities associated with the removal and disposal of contaminated and activated components and structures, including the successful termination of the 10 CFR §50 operating license. Significant decommissioning activities in this phase include: Operations, maintenance, and security associated with storing of spent fuel in the spent fuel storage pools. Transferring spent fuel from the storage pools to the ISFSI. 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 TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document P01-1604-003, Rev. 0 Section 2, Page 5 of 13 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 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 for the disposition of low-level radioactive waste. 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. Removal of control rod drive housings and the head service structure from the reactor vessel head. Segmentation of the vessel closure head. Removal and segmentation of the upper internals assemblies. Segmentation will maximize the loading of the shielded transport casks, i.e., by weight and activity. The operations are conducted under water using remotely operated tooling and contamination controls. Disassembly and segmentation of the remaining reactor internals, including the core shroud and lower core support assembly. Some material is expected to exceed Class C disposal requirements. As such, the segments will be packaged in modified fuel storage canisters for geologic disposal. Segmentation of the reactor vessel. A shielded platform is installed for segmentation as cutting operations are performed in-air using remotely operated equipment within a contamination control envelope. The water level is maintained just below the cut to minimize the working area dose rates. Segments are transferred air to containers that are stored under water, for example, in an isolated area of the refueling canal. Removal of the activated portions of the concrete biological shield and accessible contaminated concrete surfaces. If dictated by the steam TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Section 2, Page 6 of 13 generator and pressurizer removal scenarios, those portions of the associated cubicles necessary for access and component extraction are removed. Removal of the steam generators and pressurizer for material recovery and controlled disposaL The generators will be moved to an on-site processing center, the steam domes removed and the internal components segregated for recycling. The lower shell and tube bundle will be packaged for direct disposaL These components can serve as their own burial containers provided that all penetrations are properly sealed and the internal contaminants are stabilized, e.g., with grout. Steel shielding will be added, as necessary, to those external areas of the package to meet transportation limits and regulations. The pressurizer is disposed of intact. 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 hearing. 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 health and safety (e.g., waste collection and treatment systems, electrical power and ventilation systems). Removal of the steel liners from refueling canal, disposing of the activated and contaminated sections as radioactive waste. Removal of any activated/ contaminated concrete. Surveys of the decontaminated areas of the containment structure. Remediation and removal of the contaminated equipment and material from the auxiliary building and any other contaminated* facility. Radiation and contamination controls will be utilized until residual levels indicate that the structures and equipment can be released for unrestricted access and conventional demolition. This activity may necessitate the dismantling and disposition of most of TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Section 2, Page 7 of 13 the systems and components (both clean and contaminated) located within these buildings. This activity facilitates surface decontamination and subsequent verification surveys required prior to obtaining release for demolition. 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)."[18] This document incorporates the statistical approaches to survey design and data interpretation used by the EPA. It also identifies state-of-the-art, commercially available instrumentation and procedures for conducting radiological surveys. Use of this guidance ensures that the surveys are conducted in a manner that provides a high degree of confidence that applicable NRC criteria are satisfied. Once the survey is complete, the results are provided to the NRC in a format that can be verified. The NRC then reviews and evaluates the information, performs an independent confirmation of radiological site conditions, and makes a determination on final termination of the license. The NRC will terminate the operating licenses 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, safe manner, blasting, coring, drilling, scarification (surface removal), and the other decontamination activities will substantially degrade power block structures including the reactor and auxiliary buildings. Under certain circumstances, TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POI-1604-003, Rev. 0 Section 2, Page 8 of 13 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 clearly the most appropriate and cost-effective option. It is unreasonable to anticipate that these structures would be repaired and preserved after the radiological contamination is removed. The cost to dismantle site structures with a work force already mobilized on site is more efficient than if the process were deferred. Site facilities quickly degrade without maintenance, adding additional expense and creating potential hazards to the public as well as to future workers. Abandonment creates a breeding ground for vermin infestation as well as other biological hazards. This cost study presumes that non-essential structures and site facilities are dismantled as a continuation of the decommissioning activity. Foundations and exterior walls are removed to a nominal depth of three feet below grade. The three-foot depth allows for the placement of gravel for drainage, as well as topsoil, so that vegetation can be established for erosion control. Site areas affected by the dismantling activities are restored and the plant area graded as required to prevent ponding and inhibit the refloating of subsurface materials. Non-contaminated concrete rubble produced by demolition activities is processed to remove reinforcing steel and miscellaneous embedments. The processed material is then used on site to backfill foundation voids. Excess non-contaminated 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 separate and independent license (10 CFR §72) following the termination of the §50 operating licenses. Assuming the DOE starts accepting fuel from the industry in 2020, transfer of spent fuel from Diablo Canyon is anticipated to begin in 2028, and continue through the year 2051. TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POI-1604-003, Rev. 0 Section 2, Page 9 of 13 At the conclusion of the spent fuel transfer process, the ISFSI will be decommissioned. The Commission will terminate the §72 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. The ISFSI is based upon the currently licensed facility that uses purpose canisters and concrete overpacks for pad storage. For purposes of this cost analysis, it is assumed that once the inner canisters containing the spent fuel assemblies have been removed, any required decontamination performed on the storage overpack (some minor activation is assumed), and the license for the facility terminated, the concrete overpacks can be dismantled using conventional techniques for the demolition of reinforced concrete. The concrete storage pad is then removed and the area regraded. 2.2 SAFSTOR 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 that are not required to support the spent fuel pools 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 is performed. Access to contaminated areas IS secured to provide controlled access for inspection and maintenance. The engineering and planning requirements for physical dismantling activities are similar to those for the DECON alternative. Site preparations for physical dismantling are also similar to those for the DECON alternative, with the exception of certain activities, such as spent fuel pool operations and maintenance, and chemical decontamination of primary systems. Decommissioning operations are assumed to begin once the transfer of the spent fuel to the DOE is completed. TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis 2.2.1 Period 1 -Preparations Document P01-1604-003, Rev. 0 Section 2, Page 10 of 13 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. The process of placing the plant in safe-storage includes, but is not limited to, the following activities: Isolating of the spent fuel storage services and fuel handling systems 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. Transferring of the spent fuel from the storage pools to the DOE, following the minimum required cooling period in the spent fuel pools. 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 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. TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document P01-1604-003, Rev. 0 Section 2, Page 11 of 13 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 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 its own actions. The security fence, sensors, alarms, and other surveillance equipment provide security. Fire and radiation alarms are also monitored and maintained. Consistent with the DECON scenario, the spent fuel storage pools are emptied within approximately 12 years of the cessation of operations. The transfer of the spent fuel to the DOE continues throughout the dormancy period until completed in 2051. Once emptied, the ISFSI is secured for storage and decommissioned along with the power block structures in Period 4. After an optional period of storage (such that license termination is accomplished within 60 years of final shutdown), it is required that the licensee submit an application to terminate the license, along with an LTP (described in Section 2.1.2), thereby initiating the third phase. TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis 2.2.3 Periods 3 and 4 -Delayed Decommissioning Document POl-1604-003, Rev. 0 Section 2, Page 12 of 13 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. 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 this deferred scenario is the absence, in the latter, of any constraint on the availability of the fuel storage facilities 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 forty 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 estimate for this delayed scenario incorporates reduced ALARA controls for the SAFSTOR's 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 this scenario. Portions of the biological 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 TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Section 2, Page 13 of 13 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. 2.2.4 Period 5 -Site Restoration Following completion of decommissioning operations, site-restoration activities can begin. Dismantling, as a continuation of the decommissioning process, is clearly the most appropriate and effective option, as described in Section 2.1.3. The basis for the dismantling cost in this 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. TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis 3. COST ESTIMATE Document POl-1604-003, Rev. 0 Section 3, Page 1 of 27 The cost estimates prepared for decommissioning Diablo Canyon 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, specific considerations, and other pertinent assumptions, is described in this section. 3.1 BASIS OF ESTIMATE The estimates were developed using the site-specific, technical information from the 2005 analysis.

This 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,"[19] and the DOE "Decommissioning Handbook."[20] 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) are developed using local labor rates. The activity-dependent costs are 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 rely upon information available in the industry publication, "Building Construction Cost Data," published by R.S. Means. [21] 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. TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Section 3, Page 2 of 27 This analysis reflects lessons learned from TLG's involvement in the Shippingport Station Decommissioning Project, completed in 1989, as well as the decommissioning of the Cintichem reactor, hot cells, and associated facilities, completed in 1997. In addition, the planning and engineering for the Pathfinder, Shoreham, Rancho Seco, Trojan, Yankee Rowe, Big Rock Point, Maine Yankee, Humboldt Bay-3, Oyster Creek, Connecticut Yankee, and San Onofre-1 nuclear units have provided additional insight into the process, the regulatory aspects, and the technical challenges of decommissioning commercial nuclear units. Work Difficulty Factors TLG has historically applied work difficulty adjustment factors (WDFs) to account for the inefficiencies in working in a power plant environment. WDFs are assigned to each unique set of unit factors, commensurate with the inefficiencies associated with working in confined, hazardous environments. The ranges used for the WDFs are as follows: Access Factor Respiratory Protection Factor Radiation/ALARA Factor Protective Clothing Factor Work Break Factor 10% to 20% 10% to 50% 10% to 37% 10% to 30% 8.33% The factors and their associated range of values were developed in conjunction with the AIF/NESP-036 study. The application of the factors is discussed in more detail in that publication. 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 is based upon productivity information available from the "Building Construction Cost Data" publication. An activity duration critical path is used to determine the total decommissioning program schedule. The schedule is relied upon in calculating the carrying costs, which include program management, administration, field TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Section 3, Page 3 of 27 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 costs. 3.3 IMPACT OF DECOMMISSIONING MULTIPLE REACTOR UNITS In estimating the near simultaneous decommissioning of two co-located reactor units there can be opportunities to achieve economies of scale, by sharing costs between units, and coordinating the sequence of work activities. There will also be schedule constraints, particularly where there are requirements for specialty equipment and staff, or practical limitations on when final status surveys can take place. For purposes of the estimate, Units 1 and 2 are assumed to be essentially identical. Common facilities have been assigned to Unit 2. A summary of the principal impacts are listed below. The sequence of work generally follows the principal that the work is done at Unit 1 first, followed by similar work at Unit 2. This permits the experience gained at Unit 1 to be applied by the workforce at the second unit. It should be noted however, that the estimate does not consider productivity improvements at the second unit, since there is little documented experience with decommissioning two units simultaneously. The work associated with developing activity specifications and procedures can be considered essentially identical between the two units, therefore the second unit costs are assumed to be a fraction of the first unit ('" 43%). Segmenting the reactor vessel and internals will require the use of special equipment. The decommissioning project will be scheduled such that Unit 2's reactor internals and vessel are segmented immediately after the activities at Unit 1 have been completed. Some program management and support costs, particularly costs associated with the more senior positions, can be avoided with two reactors undergoing decommissioning simultaneously. As a result, the estimate is based on a "lead" unit that includes these senior positions, and a "second" unit that excludes these positions. The designation as lead is based on the unit undertaking the most complex tasks (for instance vessel segmentation) or performing tasks for the first time. The final radiological survey schedule is also affected by a two-unit decommissioning schedule. It would be considered impractical to try to complete the final status survey of Unit 1, while Unit 2 still has ongoing radiological remediation work and waste handling in process. As such, the transfer of the spent fuel from the storage pools and subsequent TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-l 604-003, Rev. 0 Section 3, Page 4 of 27 decontamination of the spent fuel pool areas is coordinated so as to synchronize the final status survey for the station. The final demolition of buildings at Units 1 and 2 are considered to take place concurrently. This is considered a reasonable assumption since access to the buildings is considered good at the station. Unit 1, as the first unit to enter decommissioning, incurs the majority of site characterization costs. Shared systems and common structures are generally assigned to Unit 2. Station costs such as emergency response fees, regulatory agency fees, corporate overhead, and insurance are generally allocated on an equal basis between the two units. 3.4 FINANCIAL COMPONENTS OF THE COST MODEL TLG's proprietary decommissioning cost model, DECCER, produces a number of distinct cost elements. These direct expenditures, however, do not comprise the total cost to accomplish the project goal, i.e., license termination and site restoration. Inherent in any cost estimate that does not rely on historical data is the inability to specify the precise source of costs imposed by factors such as tool breakage, accidents, illnesses, weather delays, and labor stoppages. In the DECCER cost model, contingency fulfills this role. Contingency is added to each line item to account for costs that are difficult or impossible to develop analytically. Such costs are historically inevitable over the duration of a job of this magnitude; therefore, this cost analysis includes funds to cover these types of expenses. 3.4.1 Contingency The activity-and period-dependent costs are combined to develop the total decommissioning cost. A contingency is then applied on a line-item basis, using one or more of the contingency types listed in the AIF/NESP-036 study. "Contingencies" are defined in the American Association of Cost Engineers "Project and Cost Engineers' Handbook" [22] 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, TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl*1604-003, Rev. 0 Section 3, Page 5 of 27 contingency is included. In the AIF/NESP-036 study, the types of unforeseeable events that are likely to occur in decommissioning are discussed and guidelines are provided for percentage contingency in each category. It should be noted that contingency, as used in this analysis, includes contingency based on a preliminary technical position[23] to reflect the California Public Utilities Commission's desire for owners to conservatively establish an appropriate contingency factor for inclusion in the decommissioning revenue requirements. Contingency Based on AIF Guidelines As stated in the AIF study contingency funds are an integral part of the total cost to complete the decommissioning process. Exclusion of this component puts at risk a successful completion of the intended tasks and, potentially, subsequent related activities. For this study, TLG examined the major activity-related problems (decontamination, segmentation, equipment handling, packaging, transport, and waste disposal) that necessitate a contingency. Individual activity contingencies ranged from 10% to 75%, depending on the degree of difficulty judged to be appropriate from TLG's actual decommissioning experience. The contingency values used in this study are as follows: Decontamination Contaminated Component Removal Contaminated Component Packaging Contaminated Component Transport Low -Level Radioactive Waste Disposal Reactor Segmentation NSSS Component Removal Reactor Waste Packaging Reactor Waste Transport Reactor Vessel Component Disposal GTCC Disposal Non-Radioactive Component Removal Heavy Equipment and Tooling Supplies Engineering Energy Characterization and Termination Surveys Construction TLG Services, Inc. 50% 25% 10% 15% 25% 75% 25% 25% 25% 50% 15% 15% 15% 25% 15% 15% 30% 15% Diablo Canyon Power Plant Decommissioning Cost Analysis Taxes and Fees Insurance Staffing Document POl-1604-003, Rev. 0 Section 3, Page 6 of 27 10% 10% 15% The contingency values are applied to the appropriate components of the estimates on a line item basis. The composite contingency value (excluding additional contingency described in the Preliminary Technical Position) for the DECON alternative is approximately 17.9%. The value for the SAFSTOR alternative is approximately 17.5%. Contingency Based on Preliminary Technical Position In addition to the contingency based on the AIF guidelines additional contingency was added to reflect the California Public Utilities Commission desire for owners to conservatively establish an appropriate contingency factor for inclusion in the decommissioning revenue requirements. Based on the previously referenced technical position, additional contingency was added to reflect an overall project contingency of 25% (both scenarios), This contingency was incorporated on a line item basis, with each line item receiving a pro-rated share of the increase. 3.4.2 Financial Risk In addition to the routine uncertainties addressed by contingency, another cost element that is sometimes necessary to consider when bounding decommissioning costs relates to uncertainty, or risk. Examples can include changes in work scope, pricing, job performance, and other variations that could conceivably, but not necessarily, occur. Consideration is sometimes necessary to generate a level of confidence in the estimate, within a range of probabilities. TLG considers these types of costs under the broad term "financial risk." Included within the category of financial risk are: 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.

Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Section 3, Page 7 of 27 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, for example, 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, the start and rate of acceptance of spent fuel by the DOE. Pricing changes for basic inputs such as labor, energy, materials, and disposal. Items subject to widespread price competition (such as materials) may not show significant variation; however, others such as waste disposal could exhibit large pricing uncertainties, particularly in markets where limited access to services is available. It has been TLG'sexperience that the results of a risk analysis, when compared with the base case estimate for decommissioning, indicate that the chances of the base decommissioning estimate's being too high is a low probability, and the chances that the estimate is too low is a higher probability. This is mostly due to the pricing uncertainty for level radioactive waste burial, and to a lesser extent due to schedule increases from changes in plant conditions and to pricing variations in the cost of labor (both craft and staff). This cost study, however, does not add any additional costs 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 estimates. 3.5 SITE-SPECIFIC CONSIDERATIONS There are a number of site-specific considerations that affect the method for dismantling and removal of equipment from the site and the degree of restoration required. The cost impact of the considerations identified below is included in this cost study. TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis 3.5.1 Spent Fuel Management Document POl-1604;.003, Rev. 0 Section 3, Page 8 of 27 The cost to dispose of spent fuel generated from plant operations is not reflected within the estimates to decommission the Diablo Canyon site. Ultimate disposition of the spent fuel is within the province of the DOE's Waste Management System, as defined by the NWPA. As such, the disposal cost is financed by a 1 mill/kWhr surcharge paid into the DOE's 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 the following assumptions. The DOE's generator allocation/receipt schedules are based upon the oldest fuel receiving the highest priority. For purposes of this analysis, acceptance of commercial spent fuel by the DOE is expected to begin in 2020. The first assemblies removed from the Diablo Canyon site are assumed to be in 2028. With an estimated, maximum rate of transfer of 3,000 metric tons of uranium (MTU)/year, [24] completion of the removal of fuel from the site is projected to be in the year 2051. Consequently, costs are included within the estimates for the long-term caretaking of the spent fuel at the Diablo Canyon site until the year 2051. The estimates incorporate a minimum cooling period of approximately 12 years for the spent fuel that resides in the storage pools when operations cease. The current Part 72 ISFSI license does not allow dry cask storage of spent fuel with burnups above 45,000 MWD/metric ton. It is assumed that PG&E can amend the Part 72 license to store the higher burnup fuel, but that as a condition of the amendment it will require longer decay times (12 years) before storing the spent fuel in the casks. In both scenarios that were analyzed, any residual fuel remaining in the pool after the 12-year period is relocated to the ISFSI to await transfer to a DOE facility. 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. The estimates include the costs to purchase, load, and transfer the fuel storage canisters. Costs are also provided for the final disposition of the facilities once the transfer is complete. TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Canister Design Document POl-1604-003, Rev. 0 Section 3, Page 9 of 27 A multi-purpose storage canister (HOLTEC HI-STORM 100 system), with a 32-fuel assemblies capacity, is assumed for future cask acquisitions. A unit cost of approximately $1,000,000 is used for pricing the internal multi-purpose canister (MPC) and concrete overpack. The DOE is assumed to provide the MPC for fuel transferred directly from the pools to the DOE at no cost to the owner. Canister Loading and Transfer An average cost of approximately $220,000 per canister is used for the labor and consumables to load/transport the spent fuel from the pools to the ISFSI pad, based upon Diablo Canyon operating experience. An average cost of approximately $200,000 per canister is used to estimate the cost to transfer the fuel from the spent fuel pools to the DOE. For estimating purposes, 50% of the pool to DOE 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 $1,500,000 and $430,000 are used for operation and maintenance of the spent fuel pools and the ISFSI, respectively. ISFSI Decommissioning Design Considerations A HI-STORM multi-purpose (storage and transport) dry shielded storage canister with a vertical, reinforced concrete storage overpack is used as a basis for the cost analyses. Approximately 50% of the overpacks are 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. Approximately 10% of the concrete and steel is assumed to be removed from the overpacks for controlled disposal. The cost to dispose of this material, as well as the demolition of the ISFSI facility, is included in the estimates. GTCC The dismantling of the reactor internals 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)). TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Section 3, Page 10 of27 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. Although there are strong arguments that GTCC waste is covered by the spent fuel contact with DOE and the fees being paid pursuant to that contract, DOE has taken the position that GTCC waste is not covered by that contract or its fees and that utilities, including PG&E, will have to pay an additional fee for the disposal of their GTCC 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 has been packaged and disposed of as high-level waste, at a cost equivalent to that envisioned for the spent fuel. For purposes of this study, GTCC is packaged in the same type of canister used to store spent fuel. Disposal costs are based upon 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 with the spent fuel in the ISFSI at the Diablo Canyon site (for the DECON alternative). In the SAFSTOR scenario, the GTCC material is shipped directly to a DOE facility as it is generated since the fuel has been removed from the site prior to the start of decommissioning and the ISFSI deactivated. 3.5.2 Reactor Vessel and Internal Components The reactor pressure vessel and internal components are segmented for disposal in shielded, reusable transportation casks. Segmentation is performed in the refueling canal, where a turntable and remote cutter are installed. The vessel is segmented in place, using a mast-mounted cutter supported off the lower head and directed from a shielded work platform installed overhead in the reactor cavity. Transportation cask specifications and transportation regulations dictate the segmentation and packaging methodology. Intact disposal of reactor vessel shells has been successfully demonstrated at several of the sites currently being decommissioned. Access to navigable waterways has allowed these large packages to be transported to the Barnwell disposal site with minimal overland travel. Intact disposal of the reactor vessel and internal components can TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Section 3, Page 11 of27 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 (including the internals). However, its location on the Columbia River simplified the transportation analysis since: the reactor package could be secured to the transport vehicle for the entire journey, i.e., the package was not lifted during transport, there were no man-made or natural terrain features between the plant site and the disposal location that could produce a large drop, and transport speeds were very low, limited by the overland transport vehicle and the river barge. As a member of the Northwest Compact, PGE had a site available for disposal of the package -the US Ecology facility in Washington State. The characteristics of this arid site proved favorable in demonstrating compliance with land disposal regulations. It is not known whether this option will be available when the Diablo Canyon plant ceases operation. Future viability of this option will depend upon the ultimate location of the disposal site, as well as the disposal site licensee's ability to accept highly radioactive packages and effectively isolate them from the environment. Consequently, the study assumes the reactor vessel will require segmentation, as a bounding condition. With lower levels of activation, the vessel shell can be packaged more efficiently than the curie-limited internal components. This will allow the use of more conventional waste packages rather than shielded casks for transport (although some shielded casks are still required). 3.5.3 Primary System Components In the DECON scenario, the reactor coolant system components are assumed to be decontaminated using chemical agents prior to the start of dismantling operations. This type of decontamination can be expected to have a significant ALARA impact, since in this scenario the removal work is done within the first few years of shutdown. A decontamination factor (average reduction) of 10 is assumed for the process. Disposal of the decontamination solution effluent is included within the estimates TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Section 3, Page 12 of 27 as a "process liquid waste" charge. In the SAFSTOR scenario, radionuclide decay is expected to provide the same benefit and, therefore, a chemical decontamination is not included. The following discussion deals with the removal and disposition of the steam generators, but the techniques involved are also applicable to other large components, such as heat exchangers, component coolers, and the pressurizer. The steam generators' size and weight, as well as their location within the reactor building, will ultimately determine the removal strategy. A trolley crane is set up for the removal of the generators. It can also be used to move portions of the steam generator cubicle walls and floor slabs from the reactor building to a location where they can be decontaminated and transported to the material handling area. Interferences within the work area, such as grating, piping, and other components are removed to create sufficient laydown space for processing these large components. The generators are rigged for removal, disconnected from the surrounding piping and supports, and maneuvered into the open area where they are lowered onto a dolly. Each generator is rotated into the horizontal position for extraction from the containment and placed onto a multi-wheeled vehicle for transport to an on-site processing and storage area. The generators are disassembled on-site with the steam domes and lightly contaminated subassemblies designated for off-site recycling. The more highly contaminated lower shell and tube bundle are packaged for direct disposal. The interior volume is filled with low-density cellular concrete for stabilization of the internal contamination. Disposal costs are based upon the displaced volume of the units. Each component is then loaded onto a rail car for transport to the disposal facility. Reactor coolant 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 coolant pumps and motors are lifted out intact, packaged, and transported for processing and/or disposal. TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis 3.5.4 Retired Components Document POl-1604-003, Rev. 0 Section 3, Page 13 of 27 Both Diablo Canyon units are expected to replace their original sets of steam generators prior to final shutdown; these retired sets will be stored on site within a concrete protective structure. The cost for transportation and disposal of these retired sets of steam generators has been included in this analysis. 3.5.5 Main Turbine and Condenser The main turbine is dismantled uSIng conventional maintenance procedures. The turbine rotors and shafts are removed to a laydown area. The lower turbine casings are removed from their anchors by controlled demolition. The main condensers are also disassembled and moved to a laydown area. Material is then prepared for transportation to an off-site recycling facility where it is surveyed and designated for either decontamination or volume! reduction, conventional disposal, or controlled disposal. Components are packaged and readied for transport in accordance with the intended disposition. 3.5.6 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)25] 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 in accordance with Part 71, as Type B. It is conceivable that the reactor, due to its limited specific activity, could qualify as LSA II or 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 vessel 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 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. TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document P01-1604-003, Rev. 0 Section 3, Page 14 of27 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. Transportation costs for Class A low-level radioactive waste are based upon the mileage to the EnergySolutions facility in Clive, Utah. Transportation costs for Class Band C waste are based upon the mileage to Andrews County, Texas. Transportation costs for off-site waste processing are based upon the mileage to Memphis, Tennessee. Truck transport costs are estimated using published tariffs from State Motor Transit. [26] 3.5.7 Low-Level Radioactive Waste Disposal To the greatest extent practical, metallic material generated in the decontamination and dismantling processes is processed to reduce the total cost of controlled disposal. Material meeting the regulatory and/or site release criterion, is released as scrap, requiring no further cost consideration. Conditioning (preparing the material to meet the waste acceptance criteria of the disposal site) and recovery of the waste stream is performed off site at a licensed processing center. Any material leaving the site is subject to a survey and release charge, at a minimum. Based on TLG's experience, rates were assumed for off..:site processing as well as survey and release. The mass of radioactive waste generated during the various decommissioning activities at the site is shown on a line-item basis in the detailed Appendices C and D, and summarized in Section 5. The quantified waste summaries shown in these tables are consistent with 10 CFR Part 61 classifications. 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 are calculated based on the exterior package dimensions for containerized material or a specific calculation for components serving as their own waste containers. The more highly activated reactor components 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 TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Section 3, Page 15 of27 Type A quantity waste), where high concentrations of gamma-emitting radionuclides limit the capacity of the shipping canisters. For the purpose of this analysis, the EnergySolutions' facility is used as the disposal site for the majority of the radioactive waste (Class A). This waste was disposed of at a rate of $62 per cubic foot for "Bulk" waste, and a rate of $252 per cubic foot for "General" waste. These rates include State of Utah taxes and Southwest Compact fees. There are no currently operating disposal facilities available to PG&E that 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. As such, waste disposal costs were estimated. The cost for disposal for Class B and C waste was $2,916 per cubic foot. This rate includes Southwest Compact fees. These disposal costs for low-level radioactive waste are based on a study sponsored by PG&E and Southern California Edison Company, "Establishing an Appropriate Disposal Rate for Low Level Radioactive Waste During Decommissioning."[13] The study was done to reflect the California Public Utilities Commission's desire for these owners to conservatively estimate their nuclear decommissioning LLRW disposal rates. 3.5.8 Site Conditions Following Decommissioning The NRC will terminate (or amend) the site license if 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 NRC's involvement in the decommissioning process will end at this point. Local building codes and state environmental regulations will dictate the next step in the decommissioning process, as well as the owner's own future plans for the site. All structures will be removed except for the switchyard. The switchyard is required for grid operations. Structures to be removed include but are not limited to the reactor buildings, auxiliary building, turbine buildings, intake and discharge structures, and steam generator storage facility. The structures that are expected to require decontamination or radiological remediation are the reactor buildings, auxiliary building, and radwaste storage building. TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document P01-1604-003, Rev. 0 Section 3, Page 16 of 27 The estimates presented herein include the dismantling of the major structures to a nominal depth of three feet below grade, backfilling and the collapsing of below grade voids, and general terra-forming such that the site upon which the power block and supplemental structures are located is transformed into a "grassy plain." The estimate does not assume the remediation of any significant volume 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. 3.6 ASSUMPTIONS The following are the major assumptions made In the development of the estimates for decommissioning the site. 3.6.1 Estimating Basis The study follows the principles of ALARA through the use of work duration adjustment factors. These factors address the impact of activities such as radiological protection instruction, mock-up training, and the use of respiratory protection and protective clothing. The factors lengthen a task's duration, increasing costs and lengthening the overall schedule. ALARA planning is considered in the costs for engineering and planning, and in the development of activity specifications and detailed procedures. Changes to worker exposure limits may impact the decommissioning cost and project schedule. 3.6.2 Labor Costs The craft labor required to decontaminate and dismantle the nuclear plant is acquired through standard site contracting practices. The current cost of labor at the site is used as an estimating basis. The owner will provide 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 PG&E. Personnel costs are based upon average salary information provided by PG&E. Overhead costs are included for site and corporate support, reduced commensurate with the staffing of the project. TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Section 3, Page 17 of27 Security, while reduced from operating levels, is maintained throughout the decommissioning for access control, material control, and to safeguard the spent fueL 3.6.3 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, 90S r , 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-34 7 4J27] Actual estimates are derived from the curie/gram values contained therein and adjusted for the different mass of the Diablo Canyon components, projected operating life, and different periods of decay. Additional short-lived isotopes were derived from CR-0130[28] and CR-0672,[29] and benchmarked to the lived values from CR-347 4. The control elements are disposed of along with the spent fuel, i.e., there is no additional cost provided for their disposal. Activation of the containment building structure is confined to the biological shield. More extensive activation (at very low levels) of the interior structures within containment has been detected at several reactors and the 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 containment building will depend upon the site release criteria selected, as well as the designated end use for the site. 3.6.4 General Transition Activities Existing warehouses are cleared of non-essential material and remain for use by PG&E and its subcontractors. The plant's operating staff performs the following activities at no additional cost or credit to the project during the transition period: TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document P01-1604-003, Rev. 0 Section 3, Page 18 of27 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. Process 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. Secondary Side Systems Selected secondary side systems are assumed to be contaminated, and will require radiological controls during dismantling, and off-site waste processing. Systems assumed to be affected include: Auxiliary Steam Condensate Extraction Steam and Heater Drip Lube Oil Distribution and Purification Turbine Steam Supply Turbine and Generator Main Condensers Main Turbine/Generator Contaminated Surfaces Contaminated concrete surfaces in the reactor buildings, fuel handling areas, containment penetration areas, radwaste storage building and auxiliary building will require decontamination by scabbling (removal of concrete surfaces to a depth of one-half inch), or a drill and spall technique (removal of concrete surfaces to a depth of two inches). Electrical Switchyard The existing electrical switchyard will remain after decommissioning in support of the utility's electrical transmission and distribution system. Scrap and Salvage The existing plant equipment is considered obsolete and suitable for scrap as deadweight quantities only. PG&E will make economically TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document P01-1604-003, Rev. 0 Section 3, Page 19 0(27 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 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 is removed at no cost or credit to the decommissioning project. Disposition may include relocation to other facilities. Spare parts are also 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 to calculate the cost of energy consumed 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 TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604 G 003, Rev. 0 Section 3, Page 20 of 27 premiums, throughout the decommissioning process, are based upon the guidance and the limits for coverage defined in the NRC's proposed rulemaking "Financial Protection Requirements for Permanently Shutdown Nuclear Power Reactors." [30] The NRC's financial protection requirements are based on varIOUS reactor (and spent fuel) configurations. Taxes Property taxes are included for all decommissioning periods. Site Modifications The perimeter fence and in-plant security barriers will be moved, as appropriate, to conform to the Site Security Plan in force during the various stages of the project. 3.7 COST ESTIMATE

SUMMARY

Schedules of expenditures are provided in Tables 3.1 and 3.2. The tables delineate the cost contributors by year of expenditures as well as cost contributor (e.g., labor, materials, and waste disposal). Additional tables in Appendices C and D provide detailed costs elements. The cost elements are also assigned to one of three subcategories: "License Termination," "Spent Fuel Management," and "Site Restoration." The subcategory "License Termination" is used to accumulate costs that are consistent with "decommissioning" as defined by the NRC in its financial assurance regulations (i.e., 10 CFR §50.75). The cost reported for this subcategory is generally sufficient to terminate the plant's operating license, recognizing that there may be some additional cost impact from spent fuel management. The "Spent Fuel Management" subcategory contains costs associated with the containerization and transfer of spent fuel from the pools to the DOE and the transfer of casks from the ISFSI to the DOE. Costs are also included for the operations of the pools and management of the ISFSI until such time that the transfer of all fuel from this facility to an off-site location (e.g., geologic repository) is complete. "Site Restoration" is used to capture costs associated with the dismantling and demolition of buildings and facilities demonstrated to be free from contamination. This includes structures never exposed to radioactive TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document P01-1604-003, Rev. 0 Section 3, Page 21 of 27 materials, as well as those facilities that have been decontaminated to appropriate levels. Structures are removed to a depth of three feet and backfilled to conform to local grade. As discussed in Section 3.4.1, it is not anticipated that the DOE will accept the GTCC waste prior to completing the transfer of spent fuel. Therefore, the cost of GTCC disposal is shown in the final year of ISFSI operation (for the DECON alternative). While designated for disposal at the geologic repository along with the spent fuel, GTCC waste is still classified as low-level radioactive waste and, as such, included as a "License Termination" expense. Decommissioning costs are reported in 2008 dollars. Costs are not inflated, escalated, or discounted over the period of expenditure (or projected lifetime of the plant), The schedules are based upon the detailed activity costs reported in Appendices C and D, along with the time line presented in Section 4.

SCHEDULE ESTIMATE Document POl-1604-003, Rev. 0 Section 4, Page 1 of 8 The schedules for the decommissioning scenarios considered in this study follow the sequences 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 plan described in Section 3.5.1. A schedule or sequence of activities for the DECON alternative from shutdown ISFSI site restoration is presented in Figure 4.1. The scheduling sequence is based on the fuel being removed from the spent fuel pools within twelve years. 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 Professional 2003" computer software. [31] 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 table, adjusted by stretching certain activities over their slack range and shifting the start and end dates of others. The following assumptions were made in the development of the decommissioning schedule: The spent fuel pools are isolated until such time that all spent fuel has been discharged from the spent fuel pools to the DOE. Decontamination and dismantling of the storage pools is initiated once the transfer of spent fuel is complete (DECON option). 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 and laydown space, and with the stringent safety measures necessary during demolition of heavy components and structures. TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Section 4, Page 2 of 8 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 schedules for decommissioning. 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 dependent costs. A second critical path is shown for the spent fuel storage period, which determines the release of the fuel pool areas for final decontamination. Project timelines are for the DECON and SAFSTOR scenarios are provided in Figures 4.2 and 4.3 with milestone dates based on the 2024 and 2025 shutdown dates for Units 1 and 2, respectively. The fuel pools are emptied approximately twelve years after shutdown, while ISFSI operations continue until the DOE can complete the transfer of assemblies to its geologic repository. Deferred decommissioning in the SAFSTOR scenarios is assumed to commence so that the physical dismantling takes place immediately after all spent fuel has been removed from the site.

RADIOACTIVE WASTES The objectives of the decommissioning process are the removal of all radioactive material from the site that would restrict its future use and the termination of the NRC license. This currently requires the remediation of all radioactive material at the site in excess of applicable legal limits. Under the Atomic Energy Act,[32] 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, Part 71 defines radioactive material as it pertains to transportation and Part 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 Parts 173-178. Shipping containers are required to be Industrial Packages (IP-l, IP-2 or IP-3, as defined in 10 CFR § 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 are shown on a line-item basis in Appendices C and D, and summarized in Tables 5.1 and 5.2. The quantified waste volume summaries shown in these tables are consistent with Part 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). While the dose rates decrease with time, radionuclides such as 137CS will still control the disposition requirements. TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document Rev. 0 Section 5, Page 2 of 6 The waste material produced in the decontamination and dismantling of the nuclear plants is primarily generated during Period 2 of DECON and Period 4 of SAFSTOR. Material that is considered potentially contaminated when removed from the radiological 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. For the purpose of this analysis, the EnergySolutions' facility is used as the disposal site for the majority of the radioactive waste (Class A). This waste was disposed of at a rate of $62 per cubic foot for "Bulk" waste, and a rate of $252 per cubic foot for "General" waste. These rates include State of Utah taxes and Southwest Compact fees. There are no currently operating disposal facilities available to PG&E that 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. As such, waste disposal costs and waste transportation distances were estimated. For purposes of estimating the Class Band C waste transportation cost it was assumed that this waste was shipped to Andrews County, Texas. The cost for disposal for Class Band C waste was $2,916 per cubic foot. This rate includes Southwest Compact fees. These disposal costs for low-level radioactive waste are based on a study sponsored by PG&E and Southern California Edison Company. The study was done to reflect the California Public Utilities Commission's desire for these owners to conservatively estimate their nuclear decommissioning LLRW disposal rates. TLG Services, Inc.

TLG Services, Inc. 10 Diablo Canyon Power Plant Decommissioning Cost Analysis 6. RESULTS Document POl-1604-003, Rev. 0 Section 6, Page 1 of 7 The analysis to estimate the costs to decommission Diablo Canyon relied upon the site-specific, technical information developed for a previous analysis prepared in 2005. While not an engineering study, the estimates provide PG&E 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 station's spent fuel pools for a minimum of twelve years following the cessation of operations for continued cooling of the assemblies. The cost projected to promptly decommission (DECON) Diablo Canyon is estimated to be $1,828.3 million. The majority of this cost (approximately 68.2%) is associated with the physical decontamination and dismantling of the nuclear plant so that the operating license can be terminated. Another 20.9% is associated with the management, interim storage, and eventual transfer of the spent fueL The remaining 10.9% is for the demolition of the designated structures and limited restoration of the site. The cost projected for deferred decommissioning (SAFSTOR) is estimated to be $1,916.6 million. The majority of this cost (approximately 55.7%) is associated with placing the plant in storage, ongoing caretaking of the plant during dormancy, and the eventual physical decontamination and dismantling of the nuclear plant so that the operating license can be terminated. Another 34.0% is associated with the management, interim storage, and eventual transfer of the spent fueL The remaining 10.3% is for the demolition of the designated structures and limited restoration of the site. The primary cost contributors, identified in Tables 6.1 thru 6.4, are either 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. The size and composition of the management organization varies with the decommissioning phase and associated site activities. However, once the operating licenses are terminated, the staff is substantially reduced for the conventional demolition and restoration of the site, and the long-term care of the spent fuel (for the DECON alternative). TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POla1604-003, Rev. 0 Section 6, Page 2 of 7 As described in this report, the spent fuel pools will remain operational for a minimum of twelve years following the cessation of operations. The pools will be isolated and an independent spent fuel island created. This will allow decommissioning operations to proceed in and around the pool areas. Over the twelve-year period, the spent fuel will be packaged into multi-purpose canisters for transfer to the ISFSI. Spent fuel will also be in storage at the ISFSI (from operations). This inventory will be transferred to the DOE after the pools are emptied. 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, disposition of the majority of the low-level radioactive material requiring controlled disposal is at the EnergySolutions' facility. Highly activated components, requiring additional isolation from the environment (GTCC), are packaged for geologic disposal. The cost of geologic disposal 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 tables for processing is inclusive, incorporating the ultimate disposition of the material. Decontamination and 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. 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, 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 TLG Services, Inc. Diablo Canyon Power Plant Decommissioning Cost Analysis Document POl-1604-003, Rev. 0 Section 6, Page 3 of 7 identified in this report. For purposes of this analysis, material is primarily moved overland by truck. Decontamination is used to reduce the plant's 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 more economical means of handling the large volumes of material produced in the dismantling of a nuclear plant. 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.
