II. Rulemaking Procedure 4

This rule is limited to the changes contained in Amendment No. 15 to Certificate of Compliance No. 1014 and does not include other aspects of the Holtec International HI-STORM 100 Cask System design. The NRC is using the direct final rule procedure to issue this amendment because it represents a limited and routine change to an existing certificate of compliance that is expected to be non-controversial. The NRC has determined that, with the requested changes, adequate protection of public health and safety will continue to be reasonably assured. The amendments to the rule will become effective on [INSERT DATE 75 DAYS AFTER DATE OF PUBLICATION IN THE FEDERAL REGISTER]. However, if the NRC receives significant adverse comments on this direct final rule by [INSERT DATE 30 DAYS AFTER DATE OF PUBLICATION IN THE FEDERAL REGISTER], then the NRC will publish a document that withdraws this action and will subsequently address the comments received in a final rule as a response to the companion proposed rule published in the Proposed Rules section of this issue of the Federal Register. Absent significant modifications to the proposed revisions requiring republication, the NRC will not initiate a second comment period on this action.

A significant adverse comment is a comment where the commenter explains why the rule would be inappropriate, including challenges to the rules underlying premise or approach, or would be ineffective or unacceptable without a change. A comment is adverse and significant if:

1) The comment opposes the rule and provides a reason sufficient to require a substantive response in a notice-and-comment process. For example, a substantive response is required when:

a) The comment causes the NRC staff to reevaluate (or reconsider) its position 5

or conduct additional analysis; b) The comment raises an issue serious enough to warrant a substantive response to clarify or complete the record; or c) The comment raises a relevant issue that was not previously addressed or considered by the NRC.

2) The comment proposes a change or an addition to the rule, and it is apparent that the rule would be ineffective or unacceptable without incorporation of the change or addition; or

3) The comment causes the NRC to make a change (other than editorial) to the rule, certificate of compliance, or technical specifications.

III. Background Section 218(a) of the Nuclear Waste Policy Act of 1982, as amended, requires that [t]he Secretary [of the Department of Energy] shall establish a demonstration program, in cooperation with the private sector, for the dry storage of spent nuclear fuel at civilian nuclear power reactor sites, with the objective of establishing one or more technologies that the [Nuclear Regulatory] Commission may, by rule, approve for use at the sites of civilian nuclear power reactors without, to the maximum extent practicable, the need for additional site-specific approvals by the Commission. Section 133 of the Nuclear Waste Policy Act states, in part, that [t]he Commission shall, by rule, establish procedures for the licensing of any technology approved by the Commission under Section 219(a) [sic: 218(a)] for use at the site of any civilian nuclear power reactor.

To implement this mandate, the Commission approved dry storage of spent nuclear fuel in NRC-approved casks under a general license by publishing a final rule 6

that added a new subpart K in part 72 of title 10 of the Code of Federal Regulations (10 CFR) entitled General License for Storage of Spent Fuel at Power Reactor Sites (55 FR 29181; July 18, 1990). This rule also established a new subpart L in 10 CFR part 72 entitled Approval of Spent Fuel Storage Casks, which contains procedures and criteria for obtaining NRC approval of spent fuel storage cask designs.

The NRC subsequently issued a final rule on May 1, 2000 (65 FR 25241), that approved the Holtec International HI-STORM 100 Cask System and added it to the list of NRC-approved cask designs in § 72.214, List of approved spent fuel storage casks, as Certificate of Compliance No. 1014.

IV. Discussion of Changes On March 20, 2019, Holtec International submitted a request to amend Certificate of Compliance No. 1014 for the HI-STORM 100 Cask System. Holtec International supplemented its request on September 16, 2019; April 28, 2020; May 15, 2020; June 12, 2020; June 22, 2020; July 30, 2020; August 14, 2020; September 1, 2020; and September 25, 2020. Amendment No. 15 revises the certificate of compliance as follows:

1. Adds a new version of a transfer cask, HI-TRAC MS (maximum shielded),

which includes an option for variable weight of the lead and water jacket and cooling passages to the bottom lid. HI-TRAC MS is to be used with all multipurpose canisters (MPCs) approved for use in Amendment Nos. 0 through 14 to the HI-STORM 100 System and the newly proposed MPC-32M, MPC-32 Version 1, and MPC-68 Version 1.

2. Includes MPC-32M for storage in the HI-STORM 100 System.

7

3. Includes MPC-32 Version 1 and MPC-68 Version 1 for storage in HI-STORM 100 System.

4. Adds the new overpack, HI-STORM 100S Version E, and allows it to be used with all MPCs approved for use in Amendment Nos. 0 through 14 to the HI-STORM 100 System and the newly proposed MPC-32M, MPC-32 Version 1, and MPC-68 Version 1.

5. Adds three additional boiling water reactor fuel types to the approved content for MPC-68M: 10x10I, 10x10J, and 11x11A.

6. Lowers the allowed ambient temperature from 80 °F to 70 °F for HI-STORM 100S Version E.

7. Adds HI-DRIP and dry ice jacket ancillary system as additional cooling when the MPC is loaded in the HI-TRAC transfer cask.

8. Allows for partial gadolinium credit for boiling water reactor fuel assemblies types 10x10 and 11x11 assembly classes in MPC-68M.

9. Includes allowance for canisters currently loaded under earlier amendments which had different helium leak test requirements.

10. Updates Drawing No. 7195 for the MPC-68M by removing dimensions which are not used in the safety analysis.

11. Includes dry ice jacket as optional alternate cooling method for short-term operation of the loaded HI-TRAC.

Holtec International originally proposed an additional change, which it did not pursue and the staff did not review. As Holtec International listed this change as proposed change #9 and the staffs preliminary safety evaluation report retained Holtec Internationals numbering, the preliminary safety evaluation report refers to changes 9, 10, and 11 as proposed changes 10, 11, and 12, respectively.

8

As documented in the preliminary safety evaluation report, the NRC performed a safety evaluation of the proposed certificate of compliance amendment request. The NRC determined that this amendment does not reflect a significant change in design or fabrication of the cask. Specifically, the NRC determined that the design of the cask would continue to maintain confinement, shielding, and criticality control in the event of each evaluated accident condition. This amendment does not reflect a significant change in design or fabrication of the cask. In addition, any resulting occupational exposure or offsite dose rates from the implementation of Amendment No. 15 would remain well within the limits specified by 10 CFR part 20, Standards for Protection Against Radiation. Thus, the NRC found there will be no significant change in the types or amounts of any effluent released, no significant increase in the individual or cumulative radiation exposure, and no significant increase in the potential for or consequences from radiological accidents.

The NRC determined that the amended Holtec International HI-STORM 100 Cask System design, when used under the conditions specified in the certificate of compliance, the technical specifications, and the NRCs regulations, will meet the requirements of 10 CFR part 72; therefore, adequate protection of public health and safety will continue to be reasonably assured. When this direct final rule becomes effective, persons who hold a general license under § 72.210 may, consistent with the license conditions under § 72.212, load spent nuclear fuel into Holtec International HI-STORM 100 Cask System casks that meet the criteria of Amendment No. 15 to Certificate of Compliance No. 1014.

V. Voluntary Consensus Standards 9

The National Technology Transfer and Advancement Act of 1995 (Pub. L. 104-113) requires that Federal agencies use technical standards that are developed or adopted by voluntary consensus standards bodies unless the use of such a standard is inconsistent with applicable law or otherwise impractical. In this direct final rule, the NRC will revise the Holtec International HI-STORM 100 Cask System design listed in

§ 72.214, List of approved spent fuel storage casks. This action does not constitute the establishment of a standard that contains generally applicable requirements.

VI. Agreement State Compatibility Under the Agreement State Program Policy Statement approved by the Commission on October 2, 2017, and published in the Federal Register on October 18, 2017 (82 FR 48535), this rule is classified as Compatibility Category NRC -

Areas of Exclusive NRC Regulatory Authority. The NRC program elements in this category are those that relate directly to areas of regulation reserved to the NRC by the Atomic Energy Act of 1954, as amended, or the provisions of 10 CFR chapter I.

Therefore, compatibility is not required for program elements in this category. Although an Agreement State may not adopt program elements reserved to the NRC, and the Category NRC does not confer regulatory authority on the State, the State may wish to inform its licensees of certain requirements by means consistent with the particular States administrative procedure laws.

VII. Plain Writing The Plain Writing Act of 2010 (Pub. L. 111-274) requires Federal agencies to 10

write documents in a clear, concise, and well-organized manner. The NRC has written this document to be consistent with the Plain Writing Act as well as the Presidential Memorandum, Plain Language in Government Writing, published June 10, 1998 (63 FR 31885).

VIII. Environmental Assessment and Finding of No Significant Impact Under the National Environmental Policy Act of 1969, as amended, and the NRCs regulations in 10 CFR part 51, Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions, the NRC has determined that this direct final rule, if adopted, would not be a major Federal action significantly affecting the quality of the human environment, and, therefore, an environmental impact statement is not required. The NRC has made a finding of no significant impact on the basis of this environmental assessment.

A. The Action The action is to amend § 72.214 to revise the Holtec International HI-STORM 100 Cask System listing within the List of approved spent fuel storage casks to include Amendment No. 15 to Certificate of Compliance No. 1014.

B. The Need for the Action This direct final rule amends the certificate of compliance for the Holtec International HI-STORM 100 Cask System design within the list of approved spent fuel storage casks that power reactor licensees can use to store spent fuel at reactor sites under a general license. Specifically, Amendment No. 15 amends the certificate of compliance as described in Section IV, Discussion of Changes, of this document, for 11

the use of the Holtec International HI-STORM 100 Cask System.

C. Environmental Impacts of the Action On July 18,1990 (55 FR 29181), the NRC issued an amendment to 10 CFR part 72 to provide for the storage of spent fuel under a general license in cask designs approved by the NRC. The potential environmental impact of using NRC-approved storage casks was analyzed in the environmental assessment for the 1990 final rule. The environmental assessment for Amendment No. 15 tiers off of the environmental assessment for the July 18, 1990, final rule. Tiering on past environmental assessments is a standard process under the National Environmental Policy Act of 1969, as amended.

The Holtec International HI-STORM 100 Cask System is designed to mitigate the effects of design basis accidents that could occur during storage. Design basis accidents account for human-induced events and the most severe natural phenomena reported for the site and surrounding area. Postulated accidents analyzed for an independent spent fuel storage installation, the type of facility at which a holder of a power reactor operating license would store spent fuel in casks in accordance with 10 CFR part 72, can include tornado winds and tornado-generated missiles, a design basis earthquake, a design basis flood, an accidental cask drop, lightning effects, fire, explosions, and other incidents.

The design of the cask would prevent loss of confinement, shielding, and criticality control in the event of each evaluated accident condition. If confinement, shielding, or criticality control are maintained, the environmental impacts resulting from an accident would be insignificant. This amendment does not reflect a significant change in design or fabrication of the cask. Because there are no significant design or 12

process changes, any resulting occupational exposure or offsite dose rates from the implementation of Amendment No. 15 would remain well within the 10 CFR part 20 limits. Therefore, the proposed certificate of compliance changes will not result in any radiological or non-radiological environmental impacts that significantly differ from the environmental impacts evaluated in the environmental assessment supporting the July 18, 1990, final rule. There will be no significant change in the types or significant revisions in the amounts of any effluent released, no significant increase in the individual or cumulative radiation exposures, and no significant increase in the potential for or consequences from radiological accidents. The NRC documented its safety findings in the preliminary safety evaluation report.

D. Alternative to the Action The alternative to this action is to deny approval of Amendment No. 15 and not issue the direct final rule. Consequently, any 10 CFR part 72 general licensee that seeks to load spent nuclear fuel into a Holtec International HI-STORM 100 Cask System in accordance with the changes described in Amendment No. 15 would have to request an exemption from the requirements of §§ 72.212 and 72.214. Under this alternative, interested licensees would have to prepare, and the NRC would have to review, a separate exemption request, thereby increasing the administrative burden upon the NRC and the costs to each licensee. The environmental impacts would be the same as the proposed action.

E. Alternative Use of Resources Approval of Amendment No. 15 to Certificate of Compliance No. 1014 would result in no irreversible commitment of resources.

13

F. Agencies and Persons Contacted No agencies or persons outside the NRC were contacted in connection with the preparation of this environmental assessment.

G. Finding of No Significant Impact The environmental impacts of the action have been reviewed under the requirements in the National Environmental Policy Act of 1969, as amended, and the NRCs regulations in subpart A of 10 CFR part 51, Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions. Based on the foregoing environmental assessment, the NRC concludes that this direct final rule entitled List of Approved Spent Fuel Storage Casks: Holtec International HI-STORM 100 Cask System, Certificate of Compliance No. 1014, Amendment No. 15 will not have a significant effect on the human environment. Therefore, the NRC has determined that an environmental impact statement is not necessary for this direct final rule.

IX. Paperwork Reduction Act Statement This direct final rule does not contain any new or amended collections of information subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).

Existing collections of information were approved by the Office of Management and Budget, approval number 3150-0132.

14

Public Protection Notification The NRC may not conduct or sponsor, and a person is not required to respond to, a request for information or an information collection requirement unless the requesting document displays a currently valid Office of Management and Budget control number.

X. Regulatory Flexibility Certification Under the Regulatory Flexibility Act of 1980 (5 U.S.C. 605(b)), the NRC certifies that this direct final rule will not, if issued, have a significant economic impact on a substantial number of small entities. This direct final rule affects only nuclear power plant licensees and Holtec International. These entities do not fall within the scope of the definition of small entities set forth in the Regulatory Flexibility Act or the size standards established by the NRC (§ 2.810).

XI. Regulatory Analysis On July 18, 1990 (55 FR 29181), the NRC issued an amendment to 10 CFR part 72 to provide for the storage of spent nuclear fuel under a general license in cask designs approved by the NRC. Any nuclear power reactor licensee can use NRC-approved cask designs to store spent nuclear fuel if 1) it notifies the NRC in advance, 2) the spent fuel is stored under the conditions specified in the casks certificate of compliance, and 3) the conditions of the general license are met. A list of NRC-approved cask designs is contained in § 72.214. On May 1, 2000 (65 FR 25241), the 15

NRC issued an amendment to 10 CFR part 72 that approved the Holtec International HI-STORM 100 Cask System design by adding it to the list of NRC-approved cask designs in § 72.214.

On March 20, 2019, and as supplemented on September 16, 2019; April 28, 2020; May 15, 2020; June 12, 2020; June 22, 2020; July 30, 2020; August 14, 2020; September 1, 2020; and September 25, 2020, Holtec International submitted a request to amend the HI-STORM 100 Cask System as described in Section IV, Discussion of Changes, of this document.

The alternative to this action is to withhold approval of Amendment No. 15 and to require any 10 CFR part 72 general licensee seeking to load spent nuclear fuel into the Holtec International HI-STORM 100 Cask System under the changes described in Amendment No. 15 to request an exemption from the requirements of §§ 72.212 and 72.214. Under this alternative, each interested 10 CFR part 72 licensee would have to prepare, and the NRC would have to review, a separate exemption request, thereby increasing the administrative burden upon the NRC and the costs to each licensee.

Approval of this direct final rule is consistent with previous NRC actions. Further, as documented in the preliminary safety evaluation report and environmental assessment, this direct final rule will have no adverse effect on public health and safety or the environment. This direct final rule has no significant identifiable impact or benefit on other government agencies. Based on this regulatory analysis, the NRC concludes that the requirements of this direct final rule are commensurate with the NRC's responsibilities for public health and safety and the common defense and security. No other available alternative is believed to be as satisfactory; therefore, this action is recommended.

16

XII. Backfitting and Issue Finality The NRC has determined that the backfit rule (§ 72.62) does not apply to this direct final rule. Therefore, a backfit analysis is not required. This direct final rule amends Certificate of Compliance No. 1014 for the Holtec International HI-STORM 100 Cask System, as currently listed in § 72.214. The amendment consists of the changes in Amendment No. 15 previously described, as set forth in the revised certificate of compliance and technical specifications.

Amendment No. 15 to Certificate of Compliance No. 1014 for the Holtec International HI-STORM 100 Cask System was initiated by Holtec International and was not submitted in response to new NRC requirements, or an NRC request for amendment. Amendment No. 15 applies only to new casks fabricated and used under Amendment No. 15. These changes do not affect existing users of the Holtec International HI-STORM 100 Cask System, and previous amendments continue to be effective for existing users. While current users of this storage system may comply with the new requirements in Amendment No. 15, this would be a voluntary decision on the part of existing users.

For these reasons, Amendment No. 15 to Certificate of Compliance No. 1014 does not constitute backfitting under § 72.62 or § 50.109(a)(1), or otherwise represent an inconsistency with the issue finality provisions applicable to combined licenses in 10 CFR part 52. Accordingly, the NRC has not prepared a backfit analysis for this rulemaking.

XIII. Congressional Review Act 17

This direct final rule is not a rule as defined in the Congressional Review Act.
