SUPPLEMENTARY INFORMATION: On May 2, 2023 (88 FR 27397), 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 TN Americas
LLC, NUHOMS[supreg] EOS Dry Spent Fuel Storage System listing within
the ``List of approved spent fuel storage casks'' to include Amendment
No. 3 to Certificate of Compliance No. 1042.
Amendment No. 3 revises the certificate of compliance to: add three
new heat load zone configurations (HLZCs) for the EOS-89BTH Dry
Shielded Canister (DSC) with increased heat load up to 1.7 kW per fuel
assembly, which reduces the minimum cooling time to 1 year; add a
variable-lead thickness EOS-TC125 for transfer with the EOS-89BTH DSC;
add ATRIUM 11 fuel as an allowable content in the EOS-89BTH DSC and
rerun the limiting GNF2 and ABB-10-C cases to reduce the statistical
uncertainties and increase the enrichment limits; update the
criticality evaluation to allow short-loading the EOS-89BTH DSC with
less than 89 fuel assemblies to increase the enrichment limits; revise
the technical specifications (TS) to allow for phased array automated
ultrasonic testing and to utilize a single pass high amperage gas
tungsten arc weld or multipass gas tungsten arc weld on the outer top
cover plate; revise the TS to reduce EOS-37PTH HLZC 1 and 2 time limit
for transfer to eight hours; incorporate a method to determine new
loading patterns based on the maximum allowable heat load per DSC and
per location specified in the TS and move all HLZCs and time limits for
transfer for the EOS-89BTH DSC transferred in the EOS-TC125 from the
technical specifications to Updated Final Safety Analysis Report
(UFSAR) Chapter 2; waive the fabrication pressure test requirement for
the single bottom forging EOS-DSCs; and make minor changes to TS and
UFSAR for consistency among DSC types and terminology clarification.
Amendment No. 3 also revises the certificate of compliance with three
scope changes including: UFSAR revisions associated with transfer cask
lifting heights and consideration of severe weather; UFSAR revisions
associated with maintaining water in the annulus; and design changes to
the Matrix Loading Crane.
In the direct final rule, the NRC stated that if no significant
adverse comments were received, the direct final rule would become
effective on July 17, 2023. The NRC did not receive any comments on the
direct final rule. Therefore, this direct final rule will become
effective as scheduled.
Dated: June 9, 2023.
