3. Includes MPC32 Version 1 and MPC68 Version 1 for storage in HI
STORM 100 System.
4. Adds the new overpack, HI

Version 1, and MPC68 Version 1.
5. Adds three additional boiling water reactor fuel types to the approved content for MPC68M: 10x10I, 10x10J, and 11x11A.
6. Lowers the allowed ambient temperature from 80 F to 70 F for HI
STORM 100S Version E.
7. Adds HIDRIP 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 MPC68M.
9. Includes allowance for canisters currently loaded under earlier amendments which had different helium leak test requirements.
10. Updates Drawing No. 7195 for the MPC68M 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 HITRAC.
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 NRC20200257 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.
