SUPPLEMENTARY INFORMATION: On March 20, 2025 (90 FR 13047), 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 NAC
International, Inc. MAGNASTOR[supreg] Storage System listing within the
``List of approved spent fuel storage casks'' to include Amendment No.
15. Amendment No. 15 revises the certificate of compliance to add a new
variation of the Lightweight MAGNASTOR[supreg] Transfer Cask design,
add a new concrete cask design, increase the maximum system heat load
capacity, add new loading patterns, add a thermal shunt for short
loading patterns, remove the 5 percent burnup penalty, increase Passive
MAGNASTOR[supreg] Transfer Cask heat load, add two new pressurized-
water reactor fuel types to support future operations, modify the
transportable storage canister lid to allow additional clearance near
the top center of the basket, and correct and clarify principal design
criteria, operating procedures, and the acceptance criteria and
maintenance program. This amendment also makes corresponding revisions
to previously approved drawings for the concrete cask, Technical
Specifications Appendix A and Appendix B, specific chapters of the
final safety analysis report, and several license drawings.
In the direct final rule, the NRC stated that if no significant
adverse comments were received, the direct final rule would become
effective on June 3, 2025. The NRC received and docketed one comment on
the companion proposed rule (90 FR 13103; March 20, 2025). An
electronic copy of the comment can be obtained from the Federal
Rulemaking website at https://www.regulations.gov under Docket ID NRC-
2024-0216 and is also available in ADAMS under Accession No.
ML25090A040. Specifically, the comment concerned the issue of the casks
being able to withstand high temperatures and the issue of preventing
leaks occurring at the site. The NRC evaluated the comment against the
criteria described in the direct final rule and determined that the
public comment received on this action did not warrant any additions or
changes to the final rule, the certificate of compliance, or the
accompanying technical specifications. The NRC is not making
substantive changes to the rule; it is apparent that the rule is
effective and acceptable as proposed, without the need for a
substantive change or addition. The comment did not raise a relevant
issue that was not previously addressed or considered by the NRC, and
the comment did not cause the NRC to either (1) reevaluate or
reconsider its position, or (2) conduct additional analyses. The NRC
has determined that the comment was not a significant adverse comment
and therefore, this direct final rule will become effective as
scheduled.
Dated: April 28, 2025.
