Federal Register / Vol. 86, No. 234 / Thursday, December 9, 2021 / Rules and Regulations
operation to develop and implement necessary procedures.
The requirement that general licensees initiating or using spent fuel dry storage operations with the TN68
Dry Storage Cask system ensure that their evaluations are included in the reports required by 72.212, Conditions of general license issued under 72.210. These reports will include appropriate considerations for the period of extended operation, a review of the UFSAR changes resulting from the certificate of compliance renewal, and a review of the NRC safety evaluation report SER related to the certificate of compliance renewal.
The requirement that future amendments and revisions to this certificate of compliance include evaluations of the impacts to aging management activities to ensure that they remain adequate for any changes to the structures, systems, and components SSCs.
The NRC made one corresponding change to the technical specifications for the initial certificate of compliance and Amendment No. 1. The change added a new section, which ensures that general licensees using the storage system develop procedures to address aging management activities required in the period of extended operation.
As documented in the preliminary SER, the NRC performed a safety evaluation of the proposed certificate of compliance renewal request. The NRC
determined that this renewal does not change the cask design or fabrication requirements in the proposed certificate of compliance renewal request. 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. In addition, any resulting occupational exposure or offsite dose rates from the renewal of the initial certificate of compliance and Amendment No. 1 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. In its SER for the renewal of the TN68 Dry Storage Cask system, the NRC staff has determined that if the conditions specified in the certificate of compliance to implement these regulations are met, adequate protection of public health and safety will continue to be reasonably assured.

This direct final rule revises the TN
68 Dry Storage Cask listing in 72.214
by renewing for 40 more years, the initial certificate and Amendment No. 1
of Certificate of Compliance No. 1027.
The renewal consists of the changes previously described, as set forth in the renewed initial certificate and amendment and their revised technical specifications. The revised technical specifications are identified in the SER.
V. Voluntary Consensus Standards The National Technology Transfer and Advancement Act of 1995 Pub. L.
104113 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 revises the TN Americas LLC, TN
68 Dry Storage Cask 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 NRCAreas 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. 111274 requires Federal agencies to 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 TN68 Dry Storage Cask listing within the List of approved spent fuel storage casks to renew, for an additional 40 years, the initial certificate and Amendment No. 1 of Certificate of Compliance No. 1027.
B. The Need for the Action This direct final rule renews the initial certificate and Amendment No. 1
of Certificate of Compliance No. 1027
for the TN Americas LLC, TN68 Dry Storage Cask system design within the list of approved spent fuel storage casks to allow power reactor licensees to store spent fuel at reactor sites in casks with the approved modifications under a general license. Specifically, this rule extends the expiration date for the TN
Americas LLC, TN68 Dry Storage Cask certificate for an additional 40 years, allowing a reactor licensee to continue using it under general license provisions in an independent spent fuel storage installation to store spent fuel in dry casks in accordance with 10 CFR part 72.
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 this renewal of the initial certificate and Amendment No. 1 of Certificate of Compliance No. 1027 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. As required by 72.240, applications for renewal of a spent fuel
