10 CFR Part 72

[NRC-2020-0050]
RIN 3150-AK47


List of Approved Spent Fuel Storage Casks: Holtec International 
HI-STORM Flood/Wind Multipurpose Canister Storage System, Certificate 
of Compliance No. 1032, Amendment No. 5

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 July 27, 2020, for the direct final rule that was 
published in the Federal Register on May 13, 2020. The direct final 
rule amends the NRC's spent fuel storage regulations by revising the 
Holtec International HI-STORM Flood/Wind Multipurpose Canister Storage 
System listing within the ``List of approved spent fuel storage casks'' 
to include Amendment No. 5 to Certificate of Compliance No. 1032. 
Amendment No. 5 revises the certificate of compliance to: Add new heat 
load patterns and revise the minimum required cooling time for two 
multipurpose canisters (MPC-89 and MPC-37); add new fuel types to the 
approved contents; allow an exception to a code to permit use of 
certain duplex stainless steels; use an analysis model to revise the 
calculation for evaluating effective fuel conductivities; add the use 
of the damaged fuel isolator; add two versions of the standard variable 
weight transfer cask; add the option of using cyclic vacuum drying; and 
make changes to the final safety analysis report to add new types of 
fuel assemblies, add a definition to it and to the certificate of 
compliance, and add the required shielding evaluation to Section 5.4.8. 
In addition, Amendment No. 5 makes several clarifications and minor 
changes.

DATES: The effective date of July 27, 2020, for the direct final rule 
published May 13, 2020 (85 FR 28479), is confirmed.

SUPPLEMENTARY INFORMATION: On May 13, 2020 (85 FR 28479), 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 Flood/Wind Multipurpose Canister Storage System 
listing within the ``List of approved spent fuel storage casks'' to 
include Amendment No. 5 to Certificate of Compliance No. 1032. 
Amendment No. 5 revises the certificate of compliance to: Add new heat 
load patterns and revise the minimum required cooling time for two 
multipurpose canisters (MPC-89 and MPC-37); add new fuel types to the 
approved contents; allow an exception to a code to permit use of 
certain duplex stainless steels; use an analysis model to revise the 
calculation for evaluating effective fuel conductivities; add the use 
of the damaged fuel isolator; add two versions of the standard variable 
weight transfer cask; add the option of using cyclic vacuum drying; and 
make changes to the final safety analysis report to add new types of 
fuel assemblies, add a definition to it and to the certificate of 
compliance, and add the required shielding evaluation to Section 5.4.8. 
In addition, Amendment No. 5 makes several clarifications and minor 
changes.
    In the direct final rule published on May 13, 2020, the NRC stated 
that if no significant adverse comments were received, the direct final 
rule would become effective on July 27, 2020. The NRC received and 
docketed one comment on the companion proposed rule (85 FR 28521; May 
13, 2020). Electronic copies of the comment can be obtained from the 
Federal Rulemaking website https://www.regulations.gov under Docket ID 
NRC-2020-0050 and is also available in ADAMS under Accession No. 
ML20168B028.
    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 was outside the scope of this 
rulemaking, did not oppose the rule, or did not propose a change to the 
rule, such that the rule would be ineffective or unacceptable without 
incorporation of the change. Therefore, the direct final rule will 
become effective as scheduled.
