SUPPLEMENTARY INFORMATION: On July 21, 2010 (75 FR 42292), the NRC
published a direct final rule amending its regulations at 10 CFR 72.214
to include Amendment No. 6 to CoC No. 1025. Amendment No. 6 changes the
configuration of the NAC-MPC storage system by the incorporation of a
single closure lid with a welded closure ring for redundant closure
into the Transportable Storage Canister (TSC) design; modification of
the TSC and basket design to accommodate up to 68 La Crosse Boiling
Water Reactor spent fuel assemblies (36 undamaged Exxon fuel assemblies
and up to 32 damaged fuel cans (in a preferential loading pattern))
that may contain undamaged Exxon fuel assemblies and damaged Exxon and
Allis Chalmers fuel assemblies and/or fuel debris; the addition of
zirconium alloy shroud compaction debris to be stored with undamaged
and damaged fuel assemblies; minor design modifications to the Vertical
Concrete Cask incorporating design features from the MAGNASTOR System
for improved operability of the system while adhering to as low as is
reasonably achievable principles; an increase in the concrete pad
compression strength from 4,000 psi to 6,000 psi; added justification
for the 6-ft. soil depth as being conservative; and other changes to
incorporate minor editorial corrections in CoC No. 1025 and Appendices
A and B of the Technical Specifications (TS). Also, the Definitions in
TS 1.1 are revised to include modifications and newly defined terms;
the Limiting Conditions for Operation and associated Surveillance
Requirements in TS 3.1 and 3.2 are revised; and editorial changes are
made to TS 5.2 and 5.4. In the direct final rule, NRC stated that if no
significant adverse comments were received, the direct final rule would
become final on October 4, 2010. The NRC did not receive any comments
on the direct final rule. Therefore, this rule will become effective as
scheduled.
Dated at Rockville, Maryland, this 17th day of September 2010.
