On March 24, 2017 (82 FR 14987), 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 add the TN Americas NUHOMS® EOS Dry Spent Fuel Storage System as CoC No. 1042. The NUHOMS® EOS System provides Start Printed Page 24458horizontal storage of high burnup spent pressurized water reactor (PWR) and boiling water reactor (BWR) fuel assemblies in dry shielded canisters (DSCs). The new PWR and BWR DSCs are the EOS-37PTH DSC and the EOS-89BTH DSC, respectively.

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 7, 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. Because no significant adverse comments were received, the direct final rule will become effective as scheduled.

The final CoC, technical specifications, and the final Safety Evaluation Report for CoC No. 1042 are available in ADAMS under Package Accession No. ML17116A277.
