SUPPLEMENTARY INFORMATION:

On June 6, 2017 (82 FR 25931), the NRC published a direct final rule amending § 72.214 of title 10 of the Code of Federal Regulations by revising the “List of approved spent fuel storage casks” to include Amendment No. 7 to CoC No. 1031 for the NAC International, MAGNASTOR® Cask System. Amendment No. 7 provides a new Passive MAGNASTOR® Transfer Cask and associated Technical Specification (TS) changes in Appendices A and B (ADAMS Accession Nos. ML16295A248 and ML16295A252), and updates Section 4.3.1(i) in Appendix A of the TSs to include revised seismic requirements. Clarifying (non-technical) changes were also made to Appendices A and B.

In the direct final rule, the NRC stated that if no significant adverse comments were received, the direct final rule would become effective on August 21, 2017. As described more fully in the direct final rule, a significant adverse comment is a comment where the commenter explains why the rule would be inappropriate, including challenges to the rule's underlying premise or approach, or would be ineffective or unacceptable without a change.

One comment on the direct final rule was submitted to Regulations.gov, however, the comment did not raise information related to this CoC and therefore was not posted. Because no significant adverse comments were received, the direct final rule will become effective as scheduled.

During the comment period for the direct final rule, the NRC identified missing change bars and formatting inconsistencies. Additionally, the NRC identified errors and omissions of text in the draft CoC and TSs associated with Amendment No. 7. In Appendix A, a number was accidently changed from 7 to 0 hours, in the table “PWR [Pressurized Water Reactor] TSC [Transportable Storage Canister] Transfer Using MTC [MAGNASTOR® Transfer Cask] Reduced Helium Backfill Time.” In Appendix B, footnote 3 omitted text; the footnote should read “0.4 years for RCC [Reactor Control Components] in the PMTC [Passive MAGNASTOR® Transfer Cask] (reduced storage location heat load). For all other cask types, 0.2 years for RCC with 10-year minimum cool time.” Additionally, the description of the PMTC was inadvertently omitted from the CoC. The NRC evaluated the figures and information provided in NAC's applications and presented its findings in Safety Evaluation Reports (SERs) (see Table 1, section 4.0 of the SER for Amendment 4 (ADAMS Accession No. ML15107A472) and sections 5.7 and 5.13 of the current SER (ADAMS Accession No. ML16295A258)), but the published draft CoC and TSs were in error. The administrative errors have been corrected in the final CoC and TSs. The final CoC, TSs, and SER for Amendment No. 7 for the MAGNASTOR® storage system can be viewed in ADAMS under Accession No. ML17013A466.
