NUCLEAR REGULATORY COMMISSION

10 CFR Part 72

[NRC-2020-0257]
RIN 3150-AK53


List of Approved Spent Fuel Storage Casks: Holtec International 
HI-STORM 100 Cask System Certificate of Compliance No. 1014, Amendment 
No. 15

AGENCY: Nuclear Regulatory Commission.

ACTION: Direct final rule; confirmation of effective date.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is confirming the 
effective date of June 14, 2021, for the direct final rule that was 
published in the Federal Register on March 29, 2021. The direct final 
rule amends the NRC's spent fuel storage regulations by revising the 
Holtec International HI-STORM 100 Cask System listing within the ``List 
of approved spent fuel storage cask'' to include Amendment No. 15 to 
Certificate of Compliance No. 1014.

DATES: Effective date: The effective date of June 14, 2021, for the 
direct final rule published March 29, 2021 (86 FR 16291), is confirmed.

SUPPLEMENTARY INFORMATION: On March 29, 2021 (86 FR 16291), the NRC 
published a direct final rule amending its regulations in part 72 of 
title 10 of the Code of Federal Regulations 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. 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.
    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 [deg]F to 70 
[deg]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.
    In the direct final rule published on March 29, 2021, the NRC 
stated that if no significant adverse comments were received, the 
direct final rule would become effective on June 14, 2021. The NRC 
received and docketed one comment on the companion proposed rule (86 FR 
16310; March 29, 2021). An electronic copy of the comment can be 
obtained from the Federal Rulemaking website https://www.regulations.gov under Docket ID NRC-2020-0257 and is also available 
in ADAMS under Accession No. ML21090A148.
    The NRC evaluated the comment against the criteria described in the 
direct final rule and determined that the comment was not significant 
and adverse. Specifically, the comment agreed with this rulemaking and, 
thus, was not adverse. Therefore, the direct final rule will become 
effective as scheduled.

    Dated: May 21, 2021.
