NUCLEAR REGULATORY COMMISSION
10 CFR Part 72
RIN 3150-AI24
List of Approved Spent Fuel Storage Casks: HI-STORM 100 Revision
5; Withdrawal of Direct Final Rule
AGENCY: Nuclear Regulatory Commission.
ACTION: Direct final rule; withdrawal.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is withdrawing a
direct final rule that would have revised the Holtec International HI-
STORM 100 cask system listing within the ``List of Approved Spent Fuel
Storage Casks'' to include Amendment No. 5 to the Certificate of
Compliance. The NRC is taking this action because it has received a
significant adverse comment in response to the direct final rule. This
significant adverse comment shall be considered as a comment to the
companion proposed rule that was published concurrently with the direct
final rule.
DATES: The final rule published on December 31, 2007 (72 FR 74162), is
withdrawn effective March 12, 2008.
FOR FURTHER INFORMATION CONTACT: Jayne M. McCausland, Office of Federal
and State Materials and Environmental Management Programs, U.S. Nuclear
Regulatory Commission, Washington, DC 20555, telephone (301) 415-6219
(e-mail: [email protected]).
SUPPLEMENTARY INFORMATION: On December 31, 2007 (72 FR 74162), the NRC
published in the Federal Register a direct final rule amending its
regulations in 10 CFR 72.214 to revise the Holtec International HI-
STORM 100 cask system listing within the ``List of Approved Spent Fuel
Storage Casks'' to include Amendment No. 5 to the Certificate of
Compliance (CoC) No. 1014. Amendment No. 5 modifies the present cask
system design to permit deletion of the requirement to perform thermal
validation tests on thermal systems; an increase in the design basis
maximum decay heat loads, namely, to 34 kilowatts (kW) for uniform
loading and 36.9 kW for regionalized loading, and introduction of a new
decay heat regionalized scheme; an increase in the maximum fuel
assembly weight for boiling water reactor fuel in the Multi-Purpose
Canister (MPC)-68 from 700 to 730 pounds; an increase in the maximum
fuel assembly weight of up to 1,720 pounds for assemblies not requiring
spacers, otherwise 1,680 pounds; changes to the assembly
characteristics of 16x16 pressurized water reactor fuel assemblies to
be qualified for storage in the HI-STORM 100 cask system; a change in
the fuel storage locations in the MPC-32 for fuel with axial power
shaping rod assemblies and in the fuel storage locations in the MPC-24,
MPC-24E, and the MPC-32 for fuel with control rod assemblies, rod
cluster control assemblies, and control element assemblies; elimination
of the restriction that fuel debris can only be loaded into the MPC-
24EF, MPC-32F, MPC-68F, and MPC-68FF canisters; introduction of a
requirement that all MPC confinement boundary components and any MPC
components exposed to spent fuel pool water or the ambient environment
be made of stainless steel or, for MPC internals, neutron absorber or
aluminum; the addition of a threshold heat load below which operation
of the Supplemental Cooling System would not be required and
modification of the design criteria to simplify the system; minor
editorial changes to include clarification of the description of
anchored casks, correction of typographical/editorial errors,
clarification of the definitions of loading operations, storage
operations, transport operations, unloading operations, cask loading
facility, and transfer cask in various locations throughout the CoC and
Final Safety Analysis Report; and modification of the definition of
non-fuel hardware to include the individual parts of the items defined
as non-fuel hardware. The direct final rule was to become effective on
March 17, 2008. The NRC also concurrently published a companion
proposed rule on December 31, 2007 (72 FR 74209).
In the direct final rule, NRC stated that if any significant
adverse comments were received, a notice of timely withdrawal of the
direct final rule would be published in the Federal Register, and the
direct final rule would not take effect.
The NRC received a significant adverse comment on the direct final
rule; therefore, the NRC is withdrawing the direct final rule. This
significant adverse comment shall be considered as a comment to the
companion proposed rule that was published concurrently with the direct
final rule. The NRC will not initiate a second comment period on the
companion proposed rule.
Dated at Rockville, Maryland, this 28th day of February, 2008.
For the Nuclear Regulatory Commission.

Executive Director for Operations.
