iii ABSTRACT Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 50.75, Reporting and Recordkeeping for Decommissioning Planning, the U.S. Nuclear Regulatory Commission (NRC) requires nuclear power reactor licensees to adjust annually, in current year dollars, their estimate of the cost to decommission their plants. The annual updates are part of the process for providing reasonable assurance that adequate funds for decommissioning will be available when needed. This NUREG, which is periodically revised, describes the formula in 10 CFR 50.75(c) that is acceptable to the NRC for determining the minimum decommissioning fund requirements for nuclear power reactor licensees. This formula is based on the estimated cost of decommissioning a reference pressurized-water reactor (PWR) and a reference boiling-water reactor (BWR) in 1986, and is escalated to current year dollars using an adjustment factor provided in 10 CFR 50.75(c)(2). The primary purpose of this report is to provide the technical basis, including references, for the estimated cost of decommissioning the reference PWR and reference BWR, and to develop the escalation factor for the low-level radioactive waste (LLW) burial cost portion of the adjustment factor. Escalation factors for the other portions of the adjustment factor (i.e., labor and energy costs), are also provided in this report.

This 20th revision of NUREG-1307, Changes in Decommissioning Waste Disposal Costs at Low-Level Waste Burial Facilities, contains burial cost escalation factors updated to the year 2024 for the reference PWR and for the reference BWR. As presented in Table 2-1, Values of Bx as a Function of LLW Burial Site and Year, multiple burial cost escalation factors are provided that reflect various LLW burial scenarios for each reactor type. These were developed because licensees may have the option to dispose of LLW at one or more of the four currently operating LLW disposal facilities in the United States licensed by the NRC or Agreement States, and the cost of disposal varies among each of the four facilities. In addition, there are various limitations on LLW disposal facility access by reactors, based upon the state in which the reactor is located. The different LLW burial scenarios are described in detail in Section 1.2, LLW Disposal Cost Scenarios.

The currently operating LLW disposal facilities that are licensed by the NRC or Agreement States are located in 1) Texas, 2) South Carolina, 3) Washington, and 4) Utah. The Texas, South Carolina, and Washington facilities are the host disposal sites for the Texas LLW Disposal Compact (Texas Compact), the Atlantic Interstate LLW Management Compact (Atlantic Compact), and the Northwest Compact on LLW Management (Northwest Compact),

respectively (Appendix E provides additional information about LLW compacts), and are referred to in this report as compact-affiliated disposal facilities. The Washington LLW disposal facility also accepts LLW generated in the three member-states of the Rocky Mountain LLW Compact (Rocky Mountain Compact). The fourth site (Utah) is not associated with a specific LLW compact, and so is referred to in this report as a non-compact disposal facility. Nuclear power plant facilities located within LLW compacts that have compact-affiliated disposal facilities can dispose of their LLW at the affiliated disposal facility or, in some cases, can dispose of a portion of their LLW at the non-compact disposal facility. Nuclear power plants not located within a LLW compact having a compact-affiliated disposal facility can dispose of their LLW at either the Texas or Utah disposal facilities. The Utah facility accepts only Class A LLW while the Texas compact-affiliated facility will accept Class A, B, and C LLW (see Section 1.1 for definitions of these LLW classes). For plants that have no disposal site available within their designated LLW compact, this report assumes that the cost for disposal of Class A LLW is the same as that for the Utah disposal facility, and the cost for disposal of Class B and C LLW is the same as that for the Texas disposal facility, and includes accounting for out-of-compact fees.

iv In the 2023 decommissioning fund status reporting cycle, in which licensees provided decommissioning trust fund data to the NRC by March 31, 2023, as required by 10 CFR 50.75(f), 71 of the 93 operating reactors in the U.S. applied LLW burial cost escalation factors based on the Table 2-1 scenario in which generators are located in States that do not have a compact-affiliated LLW disposal facility. In this current revision to NUREG-1307, estimated 2024 disposal costs for this scenario are approximately 9.5 percent lower for the reference PWR and 5.2 percent lower for the reference BWR compared to 2022 disposal costs. For the reference PWR and BWR, decrease in disposal costs are due to decreases in disposal fees for the Clive disposal facility.

In the same 2023 NRC reporting cycle, four of the 93 operating plants in the U.S. applied LLW burial cost escalation factors based on the Table 2-1 scenario in which compact affiliated generators used only the Texas compact-affiliated LLW disposal facility. In this current revision to NUREG-1307, the estimated 2024 disposal costs for the Texas compact-affiliated LLW disposal facility are generally unchanged for the reference PWR and BWR, compared to 2022 disposal costs.

Also, in the 2023 NRC reporting cycle, 13 of the 93 operating plants in the U.S. applied LLW burial cost escalation factors based on the Table 2-1 scenarios in which Atlantic Compact-affiliated generators used only the South Carolina compact-affiliated LLW disposal site or used a combination of both the South Carolina compact-affiliated disposal site and the non-compact disposal facility. (The South Carolina disposal site accepts LLW from facilities located in South Carolina, New Jersey, and Connecticut, all members of the Atlantic Compact.) In this current revision to NUREG-1307, estimated 2024 disposal costs using only the South Carolina compact-affiliated LLW disposal site are approximately 1.2 percent higher for the reference PWR and 1.7 percent higher for the reference BWR compared to 2022 disposal costs. The estimated disposal costs using the combination of both the South Carolina disposal site and the non-compact disposal facility are approximately 8.9 percent lower for the PWR and approximately 3.4 percent lower for the BWR compared to 2022 disposal costs. Increases in disposal costs were due to increases in charges for weight, activity (or curie), and irradiated hardware. Decrease in disposal cost using the combination of both the South Carolina disposal site and the non-compact disposal facility are due to decreases in the charges at the non-compact disposal facility.

Lastly, in the 2023 NRC reporting cycle, one of the 93 operating plants in the U.S. applied a LLW burial cost escalation factor based on the Table 2-1 scenario in which a compact affiliated generator used only the Washington disposal site. The estimated 2024 disposal cost using only the Washington disposal site, which accepts LLW from the 11 member-states of the Northwest and Rocky Mountain Compacts, are approximately 32.4 percent and 31.5 percent higher for the reference PWR and BWR, respectively, compared to 2022 disposal costs. Increases in disposal costs were due to increases in LLW volume, shipment, container, and dose rate charges.

Licensees may use the escalation factors from this NUREG in their cost analyses, or, per regulation at 10 CFR 50.75(b)(1), they may generate and report site-specific cost estimates that result in a total cost estimate of no less than the amount estimated by using the 10 CFR 50.75(c) formula and cost escalation factors presented in this NUREG. In the 2023 NRC reporting cycle, four of the 93 operating plants in the U.S. reported cost data using site-specific cost estimates.

Revision 20 to NUREG-1307 assumes that LLW generated from day-to-day plant operations would be disposed of using the licensees operating funds, and thus would not rely on

v decommissioning funds identified in the formula calculation. However, facilities located in states that are members of a LLW compact with no available LLW disposal site may be forced to provide interim storage for this waste (although most LLW could potentially be disposed of at a non-compact disposal facility, such as the facility located in Utah, or at the compact-affiliated disposal facility located in Texas). Accordingly, some of the LLW may ultimately need to be disposed of during decommissioning following interim storage. For those plants operating through extended license terms, this volume can become significant, and the disposal cost would not be accounted for in a decommissioning trust fund based on the formula calculation.

vii FOREWORD Nuclear power reactor licensees are required by 10 CFR 50.75, Reporting and Recordkeeping for Decommissioning Planning, to annually adjust the estimated decommissioning costs of their nuclear facilities to ensure adequate funds are available for decommissioning. The regulation (10 CFR 50.75(c)(2)) references NUREG-1307 as the appropriate source for obtaining the escalation factor for waste burial/disposition costs. This 20th revision of NUREG-1307 provides current, as of July 2024, waste burial/disposition costs using the compact-affiliated disposal facilities located in Andrews County, Texas; Barnwell, South Carolina; and Richland, Washington, and the non-compact disposal facility in Clive, Utah. In addition, this revision includes a disposal cost scenario that provides for disposal of low-level waste (LLW) using a combination of non-compact and compact-affiliated disposal facilities. Licensees can factor these numbers into the adjustment formula, as specified in 10 CFR 50.75(c)(2), to determine the minimum decommissioning fund requirement for their nuclear facilities. Although this NUREG is specifically prepared for the use of power reactor licensees, it also can be a valuable source of information for material licensees on current waste burial/disposition costs.

On July 1, 2000, the South Carolina disposal facility became the host disposal facility for the newly formed Atlantic Compact, comprised of the States of Connecticut, New Jersey, and South Carolina. Effective July 1, 2008, LLW from States that are not members of the Atlantic Compact was no longer accepted at the South Carolina disposal facility. The South Carolina Public Service Commission annually determines the costs of waste disposal at the South Carolina disposal facility and provides the site operator with an allowable operating margin.

The Richland, Washington facility only accepts LLW from the Northwest and Rocky Mountain Compacts. The Northwest Compact is comprised of the States of Idaho, Montana, Oregon, Utah, Washington, Wyoming, Alaska, and Hawaii. The Rocky Mountain Compact is comprised of the States of Colorado, Nevada, and New Mexico. The costs of disposal for this facility are determined annually based on waste generator volume projections and a maximum annual operator revenue set by the Washington Utilities and Transportation Commission. If the total operator revenue is exceeded in a given year, a rebate may be sent to the waste generator.

The Texas Compact Waste Facility (CWF), located in Andrews County, Texas, accepts LLW from both the Texas Compact and out-of-compact generators. The fees for LLW disposal are determined by the Texas Commission on Environmental Quality. Out-of-compact generators, however, must submit an import petition to the Texas Compact Commission for approval prior to shipping. The State of Texas also limits total non-compact waste disposed at the CWF to 30-percent of licensed capacity.

Since the South Carolina and Washington LLW disposal facilities are available only to licensees located within their respective compacts, an alternative available to licensees is to dispose of decommissioning Class A LLW at a non-compact disposal facility. Costs for this scenario are based on a price quote received from the operator of the non-compact disposal facility located in Utah. Revision 20 to NUREG-1307 provides waste burial/disposition cost escalation factors for this scenario, in addition to the standard scenario of disposing of 100-percent of decommissioning LLW at a compact-affiliated disposal facility.

In addition to currently available, traditional LLW disposal alternatives using licensed facilities, staff continues to evaluate LLW disposal trends and evolving industry practices that may impact minimum decommissioning fund formula cost calculations provided for in 10 CFR 50.75. The

viii U.S. Nuclear Regulatory Commission (NRC) is aware that some LLW disposal methods, such as the disposal of very low-level radioactive waste at other-than traditional LLW sites, and other alternatives, such as may be authorized under 10 CFR 20.2002, "Method for obtaining approval of proposed disposal procedures," may be less costly than disposal at traditional LLW sites. A new section, 3.6, Low Activity Waste, is included in this revision (Revision 20), which provides information about this category of LLW and the potential for its disposal at sites other than the four currently operating LLW disposal facilities licensed by the NRC or Agreement States. The NRC plans to further evaluate this disposal alternative during the next 18 months in preparation of Revision 21 of this guidance document. As part of its evaluation, NRC will engage the public and industry, as well Tribal, Federal, and local governments, to better understand the availability of and anticipated reliance by power reactor licensees on this alternative disposal method.

Based on the outcome of its engagements and research, NRC envisions the next revision of this document to incorporate LLW burial cost escalation factor and other cost-related information associated with low activity waste disposal at other-than-traditional LLW sites.

Revision 20 to NUREG-1307 assumes that LLW generated during plant operations is disposed of using operating funds. Nuclear power plants that are members of a LLW Compact that has no disposal site available for LLW may need to provide interim storage for this waste, although most LLW may be able to be disposed of at the non-compact disposal facility located in Utah or at the compact-affiliated disposal facility located in Texas. The LLW volume could be significant for plants with extended operating periods (e.g., beyond 40-years), and the disposal cost of this additional volume would not be accounted for in a decommissioning trust fund based on the formula calculation.

For licensees with no disposal site available within their designated LLW Compact, NUREG-1307, Revision 20, assumes that the cost for disposal of Class A LLW is the same as that for the Utah disposal facility, and the cost for disposal of Class B and C LLW is the same as that for the Texas disposal facility including accounting for out-of-compact fees. Accordingly, given these considerations, licensees may want to set aside additional funds to cover associated future decommissioning costs.

INTRODUCTION Nuclear power reactor licensees are required by Title 10 of the Code of Federal Regulations (10 CFR) 50.75, Reporting and Recordkeeping for Decommissioning Planning, to annually adjust the estimated decommissioning costs (in current year dollars) of their nuclear facilities to ensure adequate funds are available for decommissioning. This is one step of a multi-step process for providing reasonable assurance to the U.S. Nuclear Regulatory Commission (NRC) that adequate funds for decommissioning are planned for and accumulated beginning in licensing and through operations. NUREG-1307 provides escalation factors for the waste burial/disposition component of the decommissioning funding formula, as required by 10 CFR 50.75(c)(2). This NUREG also provides the regional escalation factors for the labor and energy components of the decommissioning fund requirement. Together, these escalation factors are used to adjust the NRC minimum decommissioning fund requirement by means of an adjustment factor. The term adjustment factor, as used in this NUREG and in 10 CFR 50.75(c)(2), refers to increases and decreases in estimated decommissioning costs subsequent to issuance of the 10 CFR 50.75 regulations. The base decommissioning fund requirements in these regulations were established in 1986 dollars. The adjustment factor escalates the cost, in 1986 dollars, to costs in todays dollars. This NUREG is updated periodically to reflect changes in waste burial/disposition costs and accounts for changes in the labor and energy values.

This NUREG provides the development of a formula for estimating decommissioning costs that are acceptable to the NRC. Sources of information used in the formula are identified. Values developed for the escalation of radioactive waste burial/disposition costs, by site and by year, are also provided. Licensees may use the formula, the coefficients, and the burial/disposition cost escalation factors from this NUREG in their analyses, or they may use an adjustment rate at least equal to the approach presented herein.

The formula and its coefficients, together with guidance to other data sources needed to complete the formula calculation, (i.e., U.S. Department of Labor, Bureau of Labor Statistics),

are summarized in Chapter 2. The development of the formula and its coefficients, with sample calculations, are presented in Chapter 3. Price schedules for LLW burial/disposition for the year 2024 are given in Appendix A for compact-affiliated and non-compact disposal facilities.

Calculations to determine the burial/disposition escalation factors, Bx, for each site and year of evaluation are summarized in Appendix B.

1.1 Definitions This section provides the definition of key terms utilized throughout this NUREG.

Low-level radioactive waste (LLW). LLW is a general term for a wide range of items that have become contaminated with radioactive material or have become radioactive through exposure to neutron radiation. Radioactive materials are present at nuclear power plants undergoing decommissioning as the result of plant operations prior to permanent shutdown and as the result of decommissioning activities. Examples include radioactively contaminated equipment, piping, tanks, hardware, and tools; concrete debris and soil; liquid radioactive waste (radwaste) treatment residues; and radioactively contaminated protective shoe covers and clothing; cleaning rags, mops, and filters. The radioactivity in these wastes can range from just above natural background levels to much higher levels, such as seen in components from inside the reactor vessel of a nuclear power plant. LLW from decommissioning activities is typically shipped to a disposal site specifically licensed for disposal of LLW.

2 LLW Classification. 10 CFR 61.55(a)(2) defines three classes of LLW acceptable for routine near-surface disposal based on its radiological and physical characteristics:

(i) Class A waste is waste that is usually segregated from other waste classes at the disposal site. The physical form and characteristics of Class A waste must meet the minimum requirements set forth in § 61.56(a). If Class A waste also meets the stability requirements set forth in § 61.56(b), it is not necessary to segregate the waste for disposal. (e.g., dry active waste, protective shoe covers and clothing)

(ii) Class B waste is waste that must meet more rigorous requirements on waste form to ensure stability after disposal. The physical form and characteristics of Class B waste must meet both the minimum and stability requirements set forth in § 61.56. (e.g., primary resin, primary filters)

(iii) Class C waste is waste that not only must meet more rigorous requirements on waste form to ensure stability but also requires additional measures at the disposal facility to protect against inadvertent intrusion. The physical form and characteristics of Class C waste must meet both the minimum and stability requirements set forth in § 61.56. (e.g., radioactive components)

LLW Compacts. The Low-Level Radioactive Waste Policy Amendments Act of 1985 (LLRWPAA) makes each state responsible for disposing of the LLW generated within its boundaries and establishes a mechanism for states to enter into compacts to establish regional LLW disposal facilities. Appendix E identifies the compacts that have been formed and the states affiliated with each. Appendix E also identifies the states that are not affiliated with any compact.

Compact-affiliated Disposal Facility. A Compact-affiliated Disposal Facility is a LLW disposal facility that has been established by a compact in accordance with the LLRWPAA. Four compacts, representing 16 states, have established three LLW disposal facilities: (1) Northwest Compact and Rocky Mountain Compact - U.S. Ecology disposal facility located in Richland, Washington, (2) Atlantic Compact - EnergySolutions disposal facility located in Barnwell, South Carolina, and (3) Texas Compact - Waste Control Specialists disposal facility located in Andrews County, Texas.

Non-compact Disposal Facility. A Non-compact Disposal Facility is a LLW disposal facility that was established outside of the framework of the LLRWPAA and is not affiliated with a compact. An example discussed in this report is the EnergySolutions disposal facility located in Clive, Utah.

Low Activity Waste. Low Activity Waste is a subset of Class A LLW. There is no regulatory definition for this category of waste. The specific definition in terms of waste acceptance criteria is established by each disposal facility with approval by the applicable state regulator.

1.2 LLW Disposal Cost Scenarios NUREG-1307, Revision 20, contains disposal costs updated to the year 2024 for the reference pressurized-water reactor (PWR) and the reference boiling-water reactor (BWR). Updated disposal costs were developed for three scenarios reflecting alternatives by which nuclear power plant (NPP) licensees may dispose of low-level waste (LLW) generated from decommissioning activities. The first scenario assumes that 100-percent of the LLW generated during decommissioning is disposed of at one of the three compact-affiliated disposal facilities located in Washington, South Carolina, and Texas. Year 2024 LLW burial cost escalation factor

3 (Bx) escalation factors, expressed as a ratio of 2024 disposal costs to the original 1986 disposal costs, are also provided. For historical purposes, disposal costs for the reference reactors and Bx escalation factors for the year 2022 are also provided. See previous revisions of NUREG-1307 for disposal costs prior to 2022.

The second scenario provides for disposing of LLW using a combination of non-compact and compact-affiliated disposal facilities. For a PWR under this scenario, 93-percent of the LLW is assumed to be disposed of at a non-compact disposal facility (Utah) and the remaining 7-percent is assumed to be disposed of at a compact-affiliated disposal facility. For a BWR under this scenario, 95-percent of the LLW is assumed to be disposed of at a non-compact disposal facility (Utah) and the remaining 5-percent is assumed to be disposed of at a compact-affiliated disposal facility.

The third scenario provides for disposing of all LLW at non-compact disposal facilities or compact-affiliated disposal facilities that accept out-of-compact waste.

The second and third scenarios, which are considered acceptable alternatives for licensees, allow NPP licensees to take advantage of potentially lower disposal costs for much of their LLW.

Bx escalation factors for each of these scenarios are also provided.

NUREG-1307, Revision 20, assumes that LLW generated during plant operations is disposed of using operating funds. Plants that are members of a LLW Compact that has no compact-affiliated disposal site available for LLW may be forced to provide interim storage for this waste (although most LLW may be able to be disposed of at the non-compact disposal facility located in Utah or at the compact-affiliated disposal facility located in Texas). Some of this waste may ultimately need to be disposed of during decommissioning. This LLW could be significant for plants with extended operating periods (e.g., beyond 40 years), and the disposal cost of this additional volume would not be accounted for in a decommissioning trust fund based on the formula calculation.

For plants that have no disposal site available within their designated LLW Compact, NUREG-1307, Revision 20, assumes that the cost for disposal of Class A LLW is the same as that for the Utah disposal facility, and that the cost for disposal of Class B and C LLW is the same as that for the Texas disposal facility, including accounting for out-of-compact fees. As new disposal scenarios become available, they will be incorporated into subsequent revisions of NUREG-1307.

DECOMMISSIONING COST ELEMENTS The elements of decommissioning costs under 50.75(c)(2) are assigned to three categories: (1) those that are proportional to labor costs, Lx; (2) those that are proportional to energy costs, Ex; and (3) those that are proportional to burial costs, Bx. The adjustment of the total decommissioning cost estimate can be expressed by:

Estimated cost (Year X) = [1986 $ cost] [A*Lx + B*Ex + C*Bx]

where A, B, and C are coefficients representing the percent or portion of the total 1986 dollar costs attributable to labor (0.65), energy (0.13), and burial (0.22), respectively, and sum to 1.0.

The factors Lx, Ex, and Bx are defined by:

Lx = labor cost escalation factor, January of 1986 to the latest month of Year X for which data are available, Ex = energy cost escalation factor, January of 1986 to the latest month of Year X for which data are available, and, Bx = LLW burial/disposition cost escalation factor, January of 1986 to the latest month of Year X for which data are available.

For labor and energy cost escalation factors used in calculating the total decommissioning cost estimate for years subsequent to 1986, Lx and Ex are based on the U.S. Department of Labor, Bureau of Labor Statistics (BLS) national producer price indexes, national consumer price indexes, and local conditions for a given site (see Chapter 3).

Bx is evaluated by recalculating the costs of burial/disposition of the radioactive wastes from the reference PWR (Reference 1) and the reference BWR (Reference 2) based on the price schedules provided by the available disposal facilities for the year of interest. The results of these recalculations are presented in Table 2-1, by site and by year. These recalculations are performed by an NRC contractor.

Effective January 1, 1993, radioactive waste from states that are not members of the Northwest Compact (comprised of Idaho, Montana, Oregon, Utah, Washington, Wyoming, Alaska, and Hawaii) or Rocky Mountain Compact (comprised of Colorado, Nevada, and New Mexico) was no longer accepted at the Washington disposal site.

Effective July 1, 2000, the South Carolina LLW burial site applied different price schedules for waste from states within and outside the then newly created Atlantic Compact (comprised of South Carolina, Connecticut, and New Jersey). Effective July 1, 2008, radioactive waste from States that are not members of the Atlantic Compact was no longer accepted at the South Carolina disposal site.

Beginning in the Spring of 2012, a new LLW disposal facility became available for disposal of waste from states within the Texas Compact (comprised of Texas and Vermont). Disposal costs for this facility were included in NUREG-1307 Revision 16 for the first time.

Licensees not located in the Northwest, Rocky Mountain, Atlantic, or Texas Compacts are generators located in states not affiliated with a LLW Compact having a compact-affiliated LLW

6 disposal facility. These generators should use the Bx values for the scenario in Table 2-1 named Bx Values for Generators Located in the Unaffiliated States and those Located in Compact-Affiliated States having no Disposal Facility (see footnote (c) in Table 2-1).

Effective with Revision 15 of this NUREG (ML130223A030, January 2013), Bx values were developed for two scenarios for each of the compact-affiliated disposal sites. These are Compact-Affiliated Disposal Facility Only and Combination of Compact-Affiliated and Non-Compact Disposal Facilities.. The Bx values for these scenarios are provided in Table 2-1 (see footnotes (d) and (e) in Table 2-1). The decision rests with the licensees to determine the scenario that best represents their particular situation.

Refer to previous revisions of NUREG-1307 for development of values prior to 2024.

(b) Effective with NUREG-1307, Revision 16, the Compact Waste Facility (CWF) in Andrews County, Texas, is available as a full-service (i.e., Class A, B, and C) LLW disposal facility for waste generators located in States affiliated with the Texas Compact.

(c)

Effective with NUREG-1307, Revision 16, the CWF in Andrews County, Texas, is also available as a full-service (i.e., Class A, B, and C) LLW disposal facility for waste generators located in States not affiliated with the Texas Compact. Out-of-compact generators, however, must submit an import petition to the Texas Compact Commission for approval prior to shipping. The State of Texas also limits total non-compact waste disposed at the CWF to 30-percent of licensed capacity and imposes additional fees on LLW disposed of from out-of-compact generators. With the availability of this full-service disposal facility to out-of-compact waste generators and the Clive, Utah disposal facility for any Class A LLW generated in the U.S., the Generic LLW Disposal Site scenario used in previous versions of NUREG-1307 is replaced with this scenario, which provides Bx values representing a composite of the disposal rates for these two disposal facilities. These Bx factors are recommended for use for plants that currently have no disposal site available within their designated LLW Compact.

(d) Effective with NUREG-1307, Revision 14, the bulk of the LLW is assumed to be dispositioned at the Clive, Utah disposal facility.

(e) Effective with NUREG-1307, Revision 15, the nomenclature for the two disposal scenarios was changed to Compact-Affiliated Disposal Facility Only and Combination of Compact-Affiliated and Non-Compact Disposal Facilities to better describe these scenarios.

DEVELOPMENT OF COST ESCALATION FACTORS AND COST ADJUSTMENT FACTOR The minimum decommissioning fund requirement, or minimum formula amount, for radiological decommissioning of a nuclear power plant, was established using January 1986 dollars, and is defined in 10 CFR 50.75(c) as follows (where P is power level of the nuclear power reactor in megawatt-thermal (MWt))1:

For a PWR (10 CFR 50.75(c)(1)(i)) -

Greater than or equal to 3400 MWt$105 million Between 1200 MWt and 3400 MWt$(75 + 0.0088P) million (For a PWR of less than 1200 MWt, use P=1200 MWt)

For a BWR (10 CFR 50.75(c)(1)(ii)) -

Greater than or equal to 3400 MWt.$135 million Between 1200 MWt and 3400 MWt.$(104 + 0.009P) million (For a BWR of less than 1200 MWt, use P=1200 MWt)

The minimum formula amount represents an actual base-year (1986) cost estimate to decommission a nuclear power plant. These 1986 costs are derived from studies finalized in the late 1970s and early 1980s (References 6 and 7) and adjusted to 1986 dollars through addendums to these PWR and BWR documented studies (References 1 and 2).

Present day minimum formula amounts rely on an adjustment factor that is applied to the initial cost estimate. In this way, the adjustment factor accounts for, or escalates, the initial formula amount to a dollar figure that incorporates inflation and other cost escalation factors.

In 10 CFR 50.75(c)(2), the adjustment factor is defined to be at least equal to 0.65L + 0.13E +

0.22B, where L and E are cost escalation factors for labor and energy, respectively, and values are to be taken from regional BLS data, and B is a cost escalation factor for waste burial and is to be taken from this report.

In summary, the adjustment factor incorporated in 10 CFR 50.75(c)(2) provides a mechanism for escalating the decommissioning fund requirement (minimum formula amount) to current year dollars to reflect inflation and other changes in economic conditions since January 1986. This section summarizes how the coefficients (i.e., 0.65, 0.13, and 0.22) in the adjustment factor were originally developed and provides updated L, E, and B cost escalation factors for use in calculating the minimum decommissioning fund requirement in current year (2024) dollars.

1 The energy input in a heat engine is measured as MWt.

10 3.1 Development of the Cost Adjustment Factor For the purpose of adjusting the 1986 minimum decommissioning formula cost estimate into todays dollars, the NRC, working with Pacific Northwest National Laboratory, determined that the total decommissioning cost could be divided into three principal components (major cost drivers) for cost escalation purposes. These components are: (1) labor, materials, and services, (2) electric power and diesel or other fuels for transportation, and (3) radioactive waste burial/disposition. The major elements contributing to each of these three components are provided in Table 3-1. The percent, or portion, of the total decommissioning cost, in January 1986 dollars, categorized as labor, materials, and services, is defined by the coefficient A. The percent, or portion, of the total decommissioning cost, in January 1986 dollars, categorized as energy and radioactive waste transportation, is defined by the coefficient B. The percent, or portion, of the total decommissioning cost, in January 1986 dollars, categorized as radioactive waste burial/disposition, is defined by the coefficient C.

11 Per Table 3-1, the C (LLW burial associated) coefficient, or that percentage representing the portion of decommissioning cost attributable to LLW burial charges, are the same (.22) for both PWRs and BWRs. The A (labor associated) and B (energy associated) coefficients differ only slightly between the two reactor types. Consequently, due to the close similarity in these coefficients, and uncertainty contained within the labor and energy assessments used in developing the minimum formula, the formula in 10 CFR 50.75(c)(2) was simplified. The simplified formula is a composite of the two reactor types by averaging the A and B coefficients derived from the separate PWR and BWR estimates. Hence, the 10 CFR 50.75(c)(2) formula for determining the decommissioning cost of both PWR and BWR reactor types assume the same coefficients, as follows:

Aaverage = 0.65 Baverage = 0.13 Caverage = 0.22 All costs categorized as labor, materials, and services are escalated from 1986 dollars to current year dollars by multiplying coefficient A (0.65) by a labor cost escalation factor Lx. All costs categorized as energy and radioactive waste transportation are escalated from 1986 dollars to current year dollars by multiplying coefficient B (0.13) by an energy cost escalation factor Ex. Values for Lx and Ex for years subsequent to 1986 are based on the national producer price indexes, national consumer price indexes, and local conditions for a given site, as described below in Sections 3.2 and 3.3, respectively. All costs categorized as radioactive waste burial/disposition are escalated from 1986 dollars to current year dollars by multiplying coefficient C (0.22) by a burial cost escalation factor Bx. The values to be used in determining Bx are derived from published cost schedules at the three compact-affiliated disposal facilities and a price quote from the non-compact disposal facility located in Utah, as described in Section 3.4.

Note that values for Bx for year 2022 and earlier, are provided in Table 2-1 for information purposes only; licensees will need only the 2024 figures for the minimum formula calculation required by March 31, 2025.

In summary, a simple equation was developed and incorporated into 10 CFR 50.75(c) to determine the minimum decommissioning fund requirement, or minimum formula amount, escalated to current year dollars. This equation is as follows:

Estimated cost (Year X) = [1986 $ Cost]*(A*Lx + B*Ex + C*Bx) where:

Estimated cost (Year X) = estimated decommissioning costs in Year X (e.g., 2024) dollars,

[1986 $ Cost] = estimated decommissioning costs in 1986 dollars (base cost for PWR/BWR in 1986 dollars),

A = percent or portion (also referred to as coefficient) of the [1986 $

Cost] attributable to labor, materials, and services (0.65),

B = percent or portion (also referred to as coefficient) of the [1986 $

Cost] attributable to energy and radioactive waste transportation (0.13),

C = percent or portion (also referred to as coefficient) of the [1986 $

Cost] attributable to radioactive waste burial/disposition (0.22),

12 Lx = labor, materials, and services cost escalation, January of 1986 to latest month of Year X for which PPI data are available, Ex = energy (electricity and fuel oil) and waste transportation cost escalation, January of 1986 to latest month of Year X for which CPI data are available, Bx = Low-level waste (LLW) burial/disposition cost escalation, January of 1986 to the latest month of Year X for which data are available,

= (Rx + Sx) / (R1986 + S1986), where:

Rx = radioactive waste burial/disposition costs (excluding surcharges) in Year X dollars, Sx = summation of surcharges in Year X dollars, R1986 = radioactive waste burial costs (excluding surcharges) in 1986 dollars, and S1986 = summation of surcharges in 1986 dollars.

3.2 Labor Cost Escalation Factors In addition to costs categorized as labor, certain materials and services are also assumed to escalate at the same rate as labor and therefore included in coefficient A. Examples of these costs include container costs, certain equipment costs, insurance costs, and costs of supplies and materials. Table 3-1 provides additional examples.

Current employment cost indexes for labor (column 3,Table 3-2, below) can be obtained from the Employment Cost Indexes, published by the BLS (Reference 4). Specifically, the appropriate regional data from Table 6 of Reference 4 entitled Employment Cost Index for total compensation, for private industry workers, by bargaining status, census region and division, and metropolitan area status should be used. These indexes may also be obtained from BLS databases available on the Internet (see Appendix C for instructions).

In order to calculate the current labor cost escalation factor (Lx) for a particular region, it must be recognized that the BLS re-indexed the Employment Cost Index (ECI) in 2005, to 100.

Accordingly, two (2) BLS cost index numbers are required to calculate the current Lx value: 1) the base labor cost escalation factor in 2005 (provided below in Table 3-2), and 2) the current Employment Cost Index (ECI) from the BLS. The December 2005 base labor cost escalation factors, by region, are presented in column 2 of Table 3-2, and current ECIs, for the sake of example, are presented in column 3. The base labor cost escalation factor is the value of Lx at the time the BLS most recently re-indexed the ECI (December 2005). As such, current values of Lx (column 4) are obtained from the simple proportion:

Lx(current)/ECI(current) = Base Lx(2005)/100 For example, to calculate Lx with a 2005 base value for the Northeast region in first quarter 2024, the below formula can be used:

13 Lx/165.0 = 2.16/100 or Lx = 2.16*165.0/100 = 3.56 Table 3-2 Regional Factors for Labor Cost Adjustment Region Base Lx (Dec 2005)

industrial electric power for onsite decommissioning, Px, and diesel or other fuels for transportation and heavy equipment operation, Fx. For the reference PWR, Ex is given by:

Ex (PWR) = 0.58Px + 0.42Fx and for the reference BWR Ex is given by:

Ex (BWR) = 0.54Px + 0.46Fx These equations are derived from Table 6-3 of Reference 1 and Table 5-3 of Reference 2. The 0.58 and 0.54 coefficients for Px are calculated as the ratio of energy cost to the total energy and fuel for transportation cost for the reference PWR and BWR, respectively. The 0.42 and 0.46 coefficients for Fx are calculated as the ratio of fuel for transportation cost to the total energy and fuel for transportation cost for the reference PWR and BWR, respectively.

The current values of Px and Fx are calculated from the Producer Price Indexes (PPI), available in the PPI Detailed Report, published by the U.S. Department of Labor, BLS (Reference 5).

These indexes also can be obtained from BLS databases available on the Internet (see Appendix C for instructions). Because the energy cost category is the cost of the electricity and fuel needed to provide essential systems and services to the plant during decommissioning, the indexes used to calculate Px should be taken from data for industrial electric power (PPI Commodity Code 0543). The transportation cost category is assumed to escalate with the cost of diesel fuel or light fuel oils. The indexes used to calculate Fx should therefore be taken from data for light fuel oils (PPI Commodity Code 0573). The BLS data available for these PPI commodity codes are currently available by region.

14 Px and Fx are the values of current producer price indexes (PPI Codes 0543 and 0573, respectively) divided by the corresponding indexes for January 1986. All PPI values are based on a value of 100 for the year 1982 (base 1982 = 100). Thus, the values of Px and Fx for March 2024 (latest data available) are2:

Px = 300.3 (March 2024 value of code 0543) 114.2 (January 1986 value of code 0543) = 2.629 Fx = 360.8 (March 2024 value of code 0573) 82.0 (January 1986 value of code 0573) = 4.400 The value of Ex for the reference PWR is therefore:

Ex (PWR) = [(0.58 x 2.629) + (0.42 x 4.400)] = 3.373.

This value of Ex = 3.373 should then be used in the equation to adjust the energy cost (to March 2024 dollars) for decommissioning a PWR.

The value for the reference BWR is:

Ex (BWR) = [(0.54 x 2.629) + (0.46 x 4.400)] = 3.444.

3.4 Waste Burial Cost Escalation Factors The waste burial cost escalation factors, Bx, for the year 2024 are provided in Table 2-1 for each of the LLW disposal sites.

To calculate the Bx for a particular LLW burial site, the cost of disposal of each of the radioactive materials identified in Tables 3-3 and 3-4 for the reference PWR and BWR, respectively, was first estimated using the year 2024 price schedules provided in Appendix A of this report for each of the LLW disposal facilities. The cost of disposal for each of the radioactive materials or components was calculated based on numerous factors, including its LLW classification (e.g.,

Class A, B, and C), its weight and volume, the number of packages, the number of shipments, its activity, and its surface dose rate. The values assumed for these factors are reported in NUREG/CR-0130 and NUREG/CR-0672 (References 6 and 7), and associated Addendums 3 and 2 (References 8 and 9), respectively, and are summarized in Tables 3-3 and 3-4 for the reference PWR and BWR, respectively. For each compact-affiliated burial site and for each of the radioactive materials, the unit cost factors provided in Appendix A are multiplied by the applicable factors provided in Tables 3-3 and 3-4 to obtain estimates for each of the following cost categories as applicable: volume or base disposal charge, irradiated hardware handling charge, cask handling charge, curie charge, shipment charge, container charge, and dose rate charge. The result for each cost category for each radioactive material was summed to obtain the total estimated disposal cost for each radioactive material for each LLW burial facility. The total estimated disposal cost for each compact-affiliated LLW burial site was determined by summing the disposal costs for all radioactive materials and then multiplying this result by 2 The PPI values for industrial electric power increased by 13.3 percent and for light fuel oils decreased by 23.7 percent from NUREG-1307, Revision 19.

15 applicable factors for taxes, fees, and permits. The results were then divided by the 1986 disposal cost estimate identified in Table 3-1 to develop the year 2024 Bx factors reported in Table 2-1.

17 A similar process was followed to develop the Bx factors for the cases where a combination of compact-affiliated and non-compact disposal facilities were used. The exception is that in these cases the Class A LLW was assumed to be disposed of at the Clive, Utah disposal facility, which only has unit cost factors based on volume. The unit cost factors were applied to the Class A LLW volumes in Tables 3-3 and 3-4 based on the LLW category assumptions provided in Table 3-5 to develop the disposal estimates for each radioactive material or component.

Appendix B provides the detailed disposal cost results for each LLW burial site and compact-affiliated/non-compact-affiliated combination by radioactive material for the current NUREG-1307 revision and Revision 19.

A comparison of the year 2024 Bx factors in Table 2-1 to the corresponding year 2022 Bx factors reported in Revision 19 of NUREG-1307, shows that 1) for the compact-affiliated disposal facility cases, the values increased for the South Carolina site and Washington site and were essentially unchanged for the Texas disposal facility and 2) for the cases with a combination of compact-affiliated and non-compact disposal facilities, the values generally decreased due to decreases in disposal fees for the non-compact disposal facility. These changes are described in Appendix A.

18 Regarding changes to the disposal price schedules, the following summarizes the changes:

For the Washington disposal facility, volume, shipment disposal rates, the charges per container, dose rate charges per container, and the annual site charges increased. The fees for environmental site surveillance did not change from year 2022.

For the South Carolina disposal facility, all of the charges and surcharges increased except for the Atlantic Compact Commission administrative surcharge, which remained unchanged.

For the Utah disposal facility, the disposal rates for both solid and liquid LLW decreased from year 2022.

For the Texas disposal facility, the waste volume charge category, the maximum curie charge, the curie inventory charge, the weight surcharge category, the dose rate surcharge category, and the irradiated hardware surcharge category did not change from year 2022.

3.5 Sample Calculations of Estimated Reactor Decommissioning Costs Four sample calculations are provided in this section to demonstrate the use of the decommissioning cost equation developed above using the appropriate cost escalation factors of Lx for labor, material, and services; Ex for energy and fuel for waste transportation; and Bx for radioactive waste burial/disposition. The coefficients A, B, and C (0.65 coefficient for labor, 0.13 coefficient for energy, and 0.22 coefficient for LLW burial) used in the examples are developed in Table 3-1. Waste generators with no LLW compact disposal site availability should use the Bx values for the generic LLW disposal site scenario (i.e., the column in Table 2-1 titled Bx Values for Generators Located in the Unaffiliated States and those Located in Compact-Affiliated States having no Disposal Facility). Sample decommissioning costs for other years are provided in Appendix D.

Example 1 (No Compact-Affiliated Disposal Facilities)

Scenario Description Reactor Type: BWR Thermal Power Rating: 3,400 MWt Location of Plant: Midwest Compact LLW Disposition Preference: Non-Compact Disposal Facilities LLW Burial Location: Non-Compact Disposal Sites (Texas and Utah)

Decommissioning Cost (2024 dollars)

= ($105 million)x[(0.65)x(3.56)+(0.13)x(3.373)+(0.22)x(12.813)] = $585 million

20 Example 4 (Compact-Affiliated Disposal Facility Only)

Scenario Description Reactor Type: BWR Thermal Power Rating: 3,400 MWt Location of Plant: Northwest Compact LLW Disposition Preference: Compact-Affiliated Disposal Facility Only LLW Burial Location: Washington Base Cost (1986 Dollars) = $135 million [from 10 CFR 50.75(c)(1)]

Lx =

Bx =

11.274 [from Table 2-1]

Decommissioning Cost (2024 dollars)

= ($135 million)x[(0.65)x(3.48)+(0.13)x(3.444)+(0.22)x(11.274)] = $701 million 3.6 Low Activity Waste Some wastes generated during decommissioning have very low levels of radioactivity that pose minimal risk to people or the environment. The volumes of these wastes may be significant (e.g., hundreds of thousands of cubic feet). The radioactivity level of this waste may be so low that it may be safely disposed of in hazardous or municipal solid waste landfills. These wastes, generally referred to as low activity or very low activity waste (there is no NRC regulatory definition for this waste category), do not necessarily require the controls specified in 10 CFR Part 61. Regulations in 10 CFR Part 20 provide an approach for the NRC to approve alternative disposal methods for these wastes.

Since 2000, the NRC has approved several 10 CFR 20.2002 requests allowing for the disposal of low or very low activity waste, including hundreds of thousands of cubic feet of concrete and other demolition debris from NPPs being decommissioned (see Reference 10 for a review of several decommissioning projects that have applied the alternative disposal methods process).

NRC approved alternative methods of disposal have typically been for disposal of very low activity waste at Resource Conservation and Recovery Act (RCRA) Subtitle C hazardous waste disposal sites and, in a few cases, at RCRA Subtitle D municipal landfill disposal facilities where long-term controls are not in place. Although these materials could be disposed in a LLW disposal facility licensed under 10 CFR Part 61, use of alternative disposal procedures under 10 CFR 20.2002 may reduce overall risk (e.g., risk associated with increased transportation distances and associated radiological and non-radiological impacts) and may preserve disposal capacity at LLW disposal facilities for higher risk waste streams, while also providing reasonable assurance of adequate protection of public health and safety and protection of the environment.

As cited in the foreword to this document, the NRC plans to further evaluate this disposal alternative in preparation for the next revision (Revision 21) of NUREG-1307. As part of its evaluation, NRC will engage the public and industry, as well as Tribal, Federal, and local governments, to better understand the availability of and anticipated reliance by power reactor licensees on this alternative disposal method. Based on the outcome of its engagements and

21 research, NRC envisions the next revision of this document to incorporate LLW burial cost escalation factor and other cost-related information associated with low activity waste disposal at other-than-traditional LLW sites.

3.7 Small Modular Reactors and Advanced Reactors As discussed in Section 3.1, the minimum decommissioning fund requirement, or minimum formula amount, defined in 10 CFR 50.75(c) for radiological decommissioning of a NPP, was based on large (greater than 1200 MWt) PWR and BWR reactor units. Small modular reactors (SMRs) and advanced reactors are of designs that differ significantly from large PWR and BWR reactor units. Accordingly, the decommissioning fund formula in 10 CFR 50.75(c) is not anticipated to be directly applicable to SMRs and advanced reactors. The NRC is currently evaluating its approach for assessing decommissioning costs for purposes of providing decommissioning funding assurance for these types of reactors.

A-1 APPENDIX A LOW-LEVEL WASTE BURIAL/DISPOSITION PRICES FOR THE CURRENT YEAR This appendix contains the price schedules for burial/disposition of LLW at the compact-affiliated LLW disposal facilities located in Texas, Washington, and South Carolina for the year 2024. Also provided is a price quote for the non-compact disposal facility located in Utah. These schedules are used to calculate the burial/disposition costs discussed in Appendix B.

A.1 Texas LLW Disposal Site Beginning in the Spring of 2012, a new facility located in Andrews County, Texas (which is owned by the State of Texas and operated by Waste Control Specialists [WCS]) became available for disposal of LLW from states within the Texas Compact (comprised of Texas and Vermont). The Texas facility, or Texas Compact Waste Facility (CWF), also accepts LLW from out-of-compact generators. The fees for LLW disposal are determined by the Texas Commission on Environmental Quality. Out-of-compact generators, however, must submit an import petition to the Texas Compact Commission for approval prior to shipping. The state of Texas also limits total non-compact waste disposed at the CWF to 30-percent of licensed capacity and charges additional fees for out-of-compact LLW.

The current approved rate schedule for disposal of LLW at the CWF is provided in Section 336.1310 (Subchapter N) of Title 30 of the Texas Administrative Code (TAC). This rate schedule is provided in Exhibit A-1. Effective November 8, 2018, the schedule no longer includes a separate waste volume charge for shielded Class A LLW, a Carbon-14 inventory charge, surcharges for weights less than or equal to 50,000 pounds, surcharges for dose rates less than or equal to 500 R/hour, or surcharges for shielded waste cask handling. All of the charges remained unchanged from 2022. The fees in this Exhibit A-1 are the maximum disposal rates that can be charged to in-compact generators. Fees charged to out-of-compact generators must be greater than these rates. Various established Texas fees charged to out-of-compact LLW currently amounts to an additional 31.25-percent on top of the rates shown in Exhibit A-1.

In addition, it is assumed that an additional 20-percent in fees/taxes is charged for out-of-compact LLW. As a result of the disposal fees being unchanged from Revision 19, the cost to disposition the LLW from a PWR and a BWR are generally unchanged.

A.2 South Carolina LLW Disposal Site Access to the South Carolina site by waste generators outside the Southeast Compact ended June 30, 1994, with site closure scheduled for December 31, 1995. However, effective July 1, 1995, the scheduled closure was canceled and access to the South Carolina facility was extended to all states except North Carolina. In June 2000, prohibition on waste from North Carolina was lifted.

Effective November 1, 1996, the operator of the South Carolina disposal site implemented a restructured waste disposal rate schedule. The restructured pricing is based on weight, dose rate, and curies with a cost incentive toward higher density packaging. All business after November 1, 1996, is through customer-specific contracts.

Effective July 1, 2008, out-of-compact waste was prohibited from disposal at the South Carolina disposal site.

A-2 Weight charges, curie surcharges, and irradiated hardware charges increased approximately 1.2 percent from the 2022 Atlantic Compact rates. The dose rate surcharges and Atlantic Compact Commission administrative surcharge remained constant. As a result, the cost to disposition the LLW from a PWR and a BWR increased approximately 1.2 percent and 1.7 percent, respectively, compared to 2022. The rate schedule for the South Carolina LLW disposal site, effective July 1, 2024, is presented in Exhibit A-2.

A.3 Washington LLW Disposal Site Beginning in 1993, the Northwest Compact imposed an annual permit fee on eligible (Northwest or Rocky Mountain Compact) waste generators based on the volume of waste to be shipped to the Washington site for disposal. For 2024, the permit fees range from $424 to $42,400.

Hospitals, universities, research centers, and industries pay the lower fees; NPPs pay the highest fee of $42,400. Permit fees for NPPs are included in this analysis for the years 1993 and later.

Beginning in 1994, the rate schedule for handling and disposing of heavy objects (greater than 5,000 pounds) at the Washington site was revised to recover additional crane rental costs from the waste generator. In 1996, the heavy object limit was raised to 17,500 pounds. A series of shipments of heavy objects for disposal was assumed that would minimize the crane surcharge and result in a one-time only heavy object charge.

Effective January 1, 1996, the operator of the Washington site implemented a restructured rate schedule based on waste volume, number of shipments, number of containers, and dose rate at the container surface. Each waste generator also is assessed an annual site availability charge based on cumulative volume and dose rate at the surface of all containers disposed. This restructured rate schedule was established in a settlement agreement between U.S. Ecology Washington, Inc., (the operator of the Washington disposal facility) and several large waste generators and was accepted by the Washington Utilities and Transportation Commission. The rate design for the restructured rate schedule was for an original period of six years, and has been renewed on this schedule since 1996. The rates are updated annually to adjust for inflation and other factors. A significant element of the rate design is the imposition of a revenue requirement that limits the profit that U.S. Ecology can earn each year. Any revenue earned in excess of this requirement must be returned to the waste generators who used the disposal facility during the year. Hence, disposal rates can vary significantly from year to year depending on the projected LLW volume and its characteristics that are received at the facility each year.

Compared with the 2022 rate schedule used in Revision 19 of NUREG-1307, the 2024 schedule reflects increases in volume rate (53.2 percent), shipment rates (35.6 percent), container rates (30.1 percent), and dose rates (about 19 percent). As a result of these rate increases, subject to the limitations described in the previous paragraph, the cost to disposition the LLW from a PWR and a BWR increased by 32.4 percent and 31.5 percent, respectively. The rate schedule for the Washington LLW disposal site, effective May 1, 2024, is presented in Exhibit A-3.

A.4 Non-compact Disposal Facilities Beginning in 2010, with Revision 14 of NUREG-1307, the EnergySolutions Clive, Utah disposal facility was explicitly included as an available, optional disposal facility for Class A LLW. This disposal facility is not associated with any of the LLW compacts and is licensed to receive Class A LLW generated from any facility in the United States. The fees for LLW disposal are

A-3 established by EnergySolutions and are not subject to review and approval by the Utah Department of Environmental Quality, which is the state of Utah regulator for the Clive disposal facility.

Disposal rates for the Clive disposal facility are obtained directly from EnergySolutions via a survey. In support of Revision 20 of NUREG-1307, a similar survey was conducted. In response to this survey, a price quote to disposition the components of the reference PWR and BWR at the Utah disposal facility was obtained. Unit costs, exclusive of taxes, were provided for several different categories of components, which are provided in Table A-1. The updated rates decreased by approximately 13.5 percent for all categories, with the exception of Evaporator Bottoms, which decreased by approximately 12 percent, from the 2024 rates. These rates assume no volume discounts, which can be substantial. The development of the Bx factor for the Combination of Compact-Affiliated and Non-Compact Disposal Facilities scenario and the Non-Compact Disposal Facilities scenario was based on these rates and assumed a 10 percent tax.

A-8 Exhibit A-2 NOTES A.

Surcharges for the Barnwell Extended Care Fund and the Decommissioning Trust Fund are included in the rates.

B.

Irradiated hardware: As a general rule, billing as irradiated hardware pertains to shipments of exceptionally high activity that require clearing of the site and special off-loading into a slit trench.

These generally include TN-RAM2 and other horizontally offloaded cask shipments. In addition to items of irradiated hardware, shipments considered irradiated hardware, for purposes of disposal, have included certain sealed sources and materials with exceptionally high levels of radioactivity.

C.

Large components (e.g., steam generators, reactor pressure vessels, coolant pumps).

Disposal fees for large components (e.g., steam generators, reactor pressure vessels, reactor coolant pumps, or items that will not fit into standard sized disposal vaults) are based on the generally applicable rates, in their entirety, except that the weight and volume used to determine density and weight related charges is calculated as follows:

1.

For packages where the large component shell qualifies as the disposal vault per Department of Health and Environmental Control (DHEC) regulations, weight and volume calculations are based on all sub-components and material contained within the inside surface of the large component shell, including all internals and any stabilization media injected by the shipper, but excluding the shell itself and all incidental external attachments required for shipping and handling; and

2.

For packages with a separate shipping container that qualifies as the disposal vault per DHEC regulations, weight and volume calculations are based on the large component, all sub-components, and material contained within the inside surface of the shipping container, including any stabilization media injected by the shipper (including that between the large component and the shipping container), but excluding the shipping container itself and all incidental external attachments required for shipping and handling.

D.

Co-mingled shipments from brokers and processors: For containers that include waste from different generators (DHEC permittees), the weight and density of the waste from each generator will be assessed separately for purposes of the weight charge in I.A. The dose of the container as a whole will be used to assess the dose multiplier in I.B. The millicurie charge 2.A. above, applies individually to each portion of waste in the shipment from each generator. The disposal site operator will provide guidelines for application of this method.

E.

Transport vehicles with additional shielding features may be subject to an additional handling fee, which will be provided upon request.

F.

In certain circumstances, the disposal site operator may assess additional charges for necessary services that are not part of and are additional to disposal rates established by the State of South 2 TN-RAM is a radioactive material cask used to transport irradiated non-fuel bearing solid materials.

A-9 Carolina. These include decontamination services and special services as described in the Barnwell Site Disposal Criteria.

G.

The disposal site operator has established the following policies and procedures, which are provided herein for informational purposes:

i.

Terms of payment are net 30 days upon presentation of invoices. A per-month service charge of one and one-half percent (11/2 percent) shall be levied on accounts not paid within thirty (30) days.

ii.

Company purchase orders or a written letter of authorization and substance acceptable to Chem-Nuclear Systems, L.L.C. (CNS) shall be received before receipt of radioactive waste material at the Barnwell Site and shall refer to CNS Radioactive Material License, the Barnwell Site Disposal Criteria, and subsequent changes thereto.

iii.

3.

Payment Arrangements

a. Initial Determination Initial determination as to the applicable rate block for each customer shall be based on projections provided by customers prior to the beginning of each calendar year. For those customers who do not intend to ship waste to the facility during the calendar year (those assigned to block No. 0) and for those customers who are initially determined to fall into block Nos. 1-2, the entire site availability charge for the year will be due and payable as of January 1. For those customers who are initially determined to fall into block Nos. 3-8, the entire site availability charge will also be due and payable as of January 1, although those customers may make special arrangements with the Company to pay the charge in equal installments at the beginning of each calendar quarter. For those generators who are initially determined to fall in block nos. 9-11, 1/12 of the site availability charge will be due and payable as of the beginning of each calendar month. These customers may pay in advance if they wish.

b. Reconciliation The site availability charge is assessed on the basis of actual volume and dose rate of waste delivered during the calendar year. Assessment of additional amounts, or refunds of overpaid amounts, will be made as appropriate to reconcile the initial determination regarding applicable rate block with the actual volume and dose rates during the calendar year.

B-1 APPENDIX B CALCULATION OF LOW-LEVEL WASTE BURIAL/DISPOSITION COST ESCALATION FACTORS The calculations necessary to determine the costs for burial/disposition of radioactive wastes resulting from decommissioning the reference PWR and the reference BWR are performed using spreadsheet models. The spreadsheets evaluate the burial/disposition costs for each of the items originally budgeted in the PWR and BWR decommissioning studies and in Addendums 4 and 3 (References 1 and 2), respectively, to those reports. The costs are based on the published price schedules from the compact-affiliated disposal facilities and a price quote from the non-compact disposal facility located in Utah.

The Bx values reported in this document reflect the updated rate schedules and price quote. All the calculations are based on the same inventory of radioactive wastes as was postulated in the 1986 and 1978-1980 analyses. Starting in 1988, the inventories also included post-Three Mile Island (TMI)-2 contributions from the reference PWR and the reference BWR (References 1 and 2).

B.1 Generators Located in States Not Affiliated with a Compact having a Disposal Facility Both the Utah and Texas disposal facilities are available for the disposal of all LLW regardless of whether a generator has a compact-affiliated disposal facility available for disposal of their LLW or not. The Utah facility can only dispose of Class A LLW, while the Texas facility is a full-service disposal facility and so can dispose of Class A, B, and C LLW (subject to the constraints described in Section A.3). For the year 2024, Bx = 12.405 and 11.658 for a PWR and BWR, respectively, for disposal of most Class A LLW at the Utah non-compact site and for the remainder of LLW at the Texas LLW disposal site. The Bx values include the additional fees imposed for the disposal of non-compact LLW at the Texas disposal facility. The Bx values are summarized in Table 2-1. These Bx values should be used by generators located in States not affiliated with a compact having a disposal facility.

Waste burial costs for the year 2024 were developed using both the rate schedules for the Texas disposal facility provided in Exhibit A-1, and the associated additional fees for out-of-compact waste, and the price quote for the non-compact disposal facility provided in Table A-1.

The spreadsheet calculations for the current year, which are too voluminous to present here, are summarized in Table B-1 and Table B-2 for PWR and BWR plants, respectively. For comparison purposes, Table B-3 and Table B-4 provide summaries of the waste burial/disposition costs for 2022 for PWR and BWR plants, respectively.

B.2 Texas LLW Disposal Site For the year 2024, Bx = 6.650 and 6.009 for a PWR and BWR, respectively, at the Texas disposal facility. These Bx values reflect the adjustment in waste burial costs at the Texas LLW disposal site normalized to the 1986 Washington LLW disposal site burial costs.

Waste burial costs for the year 2024 were developed using the rate schedules provided in Exhibit A-1. The spreadsheet calculations for the current year, which are too voluminous to present here, are summarized in Table B-5 and Table B-6 for PWR and BWR plants,

B-2 respectively. For comparison purposes, Table B-7 and Table B-8 provide summaries of the waste burial costs at the Texas LLW disposal site for 2022 for PWR and BWR plants, respectively.

B.3 South Carolina LLW Disposal Site For the year 2024, Bx = 39.197 and 34.514 for a PWR and BWR, respectively, at the South Carolina disposal facility. These Bx values reflect the adjustment in waste burial costs at the South Carolina LLW disposal site normalized to the 1986 Washington LLW disposal site burial costs. Bx values for several previous revisions of NUREG-1307 are summarized in Table 2-1.

Waste burial costs for the year 2024 were developed using the rate schedules provided in Exhibit A-2. The spreadsheet calculations for the current year, which are too voluminous to present here, are summarized in Table B-9 and Table B-10 for PWR and BWR plants, respectively. For comparison purposes, Table B-11 and Table B-12 provide summaries of the waste burial costs at the South Carolina LLW disposal site for 2022 for PWR and BWR plants, respectively.

B.4 Washington LLW Disposal Site The LLW disposal site located in Washington was used to develop the original decommissioning cost estimates for the reference PWR and BWR. These estimates are the basis for the minimum decommissioning fund requirement specified in 10 CFR 50.75(c), which is in 1986 dollars. Thus, Bx = 1.0/1.0 (for PWR/BWR) for 1986.

For the year 2024, Bx = 13.260 and 11.274 for a PWR and BWR, respectively, at the Washington disposal facility. These Bx values reflect the adjustment in waste burial costs at the Washington LLW disposal site since 1986. Bx values for several previous revisions of NUREG-1307 are summarized in Table 2-1.

Waste burial costs for the year 2024 were developed using the rate schedule provided in Exhibit A-1. The spreadsheet calculations for the current year, which are too voluminous to present here, are summarized in Table B-13 and Table B-14 for PWR and BWR plants, respectively. For comparison purposes, Table B-15 and B-16 provide summaries of the waste burial costs at the Washington LLW disposal site for 2022 for PWR and BWR plants, respectively.

B.5 Combination of Non-Compact and Compact-Affiliated Disposal Facilities For the year 2024, Bx = 9.471 and 8.596 for a PWR and BWR, respectively, for disposal of most Class A LLW at the Utah non-compact disposal site, and for the remainder of LLW at the Washington LLW disposal site. Bx = 12.813 and 15.017 for a PWR and BWR, respectively, for disposal of most Class A LLW at the Utah non-compact disposal site, and for the remainder of LLW at the South Carolina disposal site. Bx = 10.923 and 9.862 for a PWR and BWR, respectively, for disposal of most Class A LLW at the Utah non-compact site, and for the remainder of LLW at the Texas LLW disposal site. Bx values are summarized in Table 2-1.

Waste burial costs for the year 2024 were developed using both the rate schedules for the compact-affiliated disposal facilities provided in Exhibits A-1, A-2, and A-3 and for the price quote for the non-compact disposal facility provided in Table A-2. The spreadsheet calculations for the current year, which are too voluminous to present here, are summarized in Table B-17 through Table B-22 for the Texas, South Carolina, and Washington LLW disposal sites for PWR

B-3 and BWR plants, respectively. For comparison purposes, Table B-23 through Table B-28 provide summaries of the Texas, South Carolina, and Washington waste burial/disposition costs for 2022 for PWR and BWR plants, respectively.

B.6 Other As other low-level radioactive waste burial sites come into service in the interstate compacts, values for Bx will be calculated using the price schedules for each of those sites and will be incorporated into subsequent issues of this NUREG. Those materials whose activity concentrations exceed the limits for Class C LLW are identified by footnote as greater-than-Class C (GTCC) material. Because the analyses in this NUREG postulate placing this material in a LLW disposal facility, the disposal costs for this material may be significantly overestimated compared with high-density packaging and geologic repository disposal. It may also be feasible to store GTCC waste in independent spent fuel storage installations (ISFSIs) or other interim storage facilities, as permitted by 10 CFR Part 72, Licensing Requirements for the Independent Storage of Spent Nuclear Fuel, High-Level Radioactive Waste, and Reactor-Related Greater Than Class C Waste.
