NUCLEAR REGULATORY COMMISSION

10 CFR Part 72

[NRC-2010-0183]
RIN 3150--AI88


List of Approved Spent Fuel Storage Casks: NAC-MPC System, 
Revision 6

AGENCY: Nuclear Regulatory Commission.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is proposing to 
amend its spent fuel storage cask regulations by revising the NAC 
International, Inc. (NAC), NAC-MPC System listing within the ``List of 
Approved Spent Fuel Storage Casks'' to include Amendment No. 6 to 
Certificate of Compliance (CoC) Number 1025. Amendment No. 6 would 
include the following changes to the configuration of the NAC-MPC 
storage system as noted in Appendix B of the Technical Specifications 
(TS): 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 (VCC) incorporating design features from 
the MAGNASTOR system for improved operability of the system while 
adhering to as low as is reasonably achievable (ALARA) principles; an 
increase in the concrete pad compression strength from 4000 psi to 6000 
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 TS. Also, the Definitions in TS 1.1 
will be revised to include modifications and newly defined terms; the 
Limiting Conditions for Operation and associated Surveillance 
Requirements in TS 3.1 and 3.2 will be revised; and editorial changes 
will be made to TS 5.2 and 5.4.

DATES: Comments on the proposed rule must be received on or before 
August 20, 2010.

Submitting Comments and Accessing Information

    Comments submitted in writing or in electronic form will be posted 
on the NRC Web site and on the Federal rulemaking Web site http://www.regulations.gov. Because your comments will not be edited to remove 
any identifying or contact information, the NRC cautions you against 
including any information in your submission that you do not want to be 
publicly disclosed. The NRC requests that any party soliciting or 
aggregating comments received from other persons for submission to the 
NRC inform those persons that the NRC will not edit their comments to 
remove any identifying or contact information, and therefore, they 
should not include any information in their comments that they do not 
want publicly disclosed.
    You can access publicly available documents related to this 
document using the following methods:
    NRC's Public Document Room (PDR): The public may examine and have 
copied for a fee publicly available documents at the NRC's PDR, Room O-
1F21, One White Flint North, 11555 Rockville Pike, Rockville, Maryland.
    NRC's Agencywide Documents Access and Management System (ADAMS): 
Publicly available documents created or received at the NRC are 
available electronically at the NRC's Electronic Reading Room at http://www.nrc.gov/reading-rm/adams.html. From this page, the public can gain 
entry into ADAMS, which provides text and image files of NRC's public 
documents. If you do not have access to ADAMS or if there are problems 
in accessing the documents located in ADAMS, contact the NRC's PDR 
reference staff at 1-800-397-4209, or 301-415-4737, or by e-mail to

Procedural Background

    This rule is limited to the changes contained in Amendment 6 to CoC 
No. 1025 and does not include other aspects of the NAC-MPC System 
design. Because NRC considers this action noncontroversial and routine, 
the NRC is publishing this proposed rule concurrently as a direct final 
rule in the Rules and Regulations section of this Federal Register. 
Adequate protection of public health and safety and the environment 
continues to be ensured. The direct final rule will become effective on 
October 4, 2010. However, if the NRC receives significant adverse 
comments on the direct final rule by August 20, 2010, then the NRC will 
publish a document that withdraws the direct final rule. If the direct 
final rule is withdrawn, the NRC will address the comments received in 
response to the proposed revisions in a subsequent final rule. Absent 
significant modifications to the proposed revisions requiring 
republication, the NRC will not initiate a second comment period on 
this action in the event the direct final rule is withdrawn.
    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. A comment is adverse and significant if:
    (1) The comment opposes the rule and provides a reason sufficient 
to require a substantive response in a notice-and-comment process. For 
example, a substantive response is required when:
    (a) The comment causes the NRC staff to reevaluate (or reconsider) 
its position or conduct additional analysis;
    (b) The comment raises an issue serious enough to warrant a 
substantive response to clarify or complete the record; or
    (c) The comment raises a relevant issue that was not previously 
addressed or considered by the NRC staff.
    (2) The comment proposes a change or an addition to the rule, and 
it is apparent that the rule would be ineffective or unacceptable 
without incorporation of the change or addition.
    (3) The comment causes the NRC staff to make a change (other than 
editorial) to the rule, CoC, or TS.
    For additional procedural information and the regulatory analysis, 
see the direct final rule published in the Rules and Regulations 
section of this Federal Register.
