NUCLEAR REGULATORY COMMISSION
[NRC-2014-0273]
Impact of Variation in Environmental Conditions on the Thermal
Performance of Dry Storage Casks
AGENCY: Nuclear Regulatory Commission.
ACTION: Draft NUREG; request for comment.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing for
public comment a draft NUREG, NUREG-2174, ``Impact of Variation in
Environmental Conditions on the Thermal Performance of Dry Storage
Casks.'' This report evaluates spent fuel dry storage cask thermal
impact of varying environmental conditions and transient thermal
behavior when subjected to a sudden boundary condition change.
Different cask designs are evaluated (vertical underground, vertical
aboveground, and horizontal aboveground). The NRC staff will consider
the analysis results in this report when performing technical reviews,
applicants should consider them when applying for cask certification.
These results can be used as additional guidance when considering the
thermal impact of the environmental factors in the thermal performance
of dry storage systems.
DATES: Submit comments by May 4, 2015. Comments received after this
date will be considered if it is practical to do so, but the Commission
is able to ensure consideration only for comments received before this
date.
ADDRESSES: You may submit comments by any of the following methods

ADAMS. The NRC does not routinely edit comment submissions to remove
identifying or contact information.
If you are requesting or aggregating comments from other persons
for submission to the NRC, then you should inform those persons not to
include identifying or contact information that they do not want to be
publicly disclosed in their comment submission. Your request should
state that the NRC does not routinely edit comment submissions to
remove such information before making the comment submissions available
to the public or entering the comment submissions into ADAMS.
II. Discussion
The NRC is issuing Draft ``Impact of Variation in Environmental
Conditions on the Thermal Performance of Dry Storage Casks.'' The draft
NUREG-2174 report evaluates the thermal impact of varying environmental
conditions and transient thermal behavior when subjected to a sudden
boundary condition change in spent fuel dry storage casks. Different
cask designs are evaluated in the draft NUREG report. The NRC will
consider the analysis results in the report when performing technical
reviews, therefore applicants should consider them when applying for
cask certification. The analysis results in draft NUREG-2174 can be
used as additional guidance when considering the thermal impact of the
environmental factors in the thermal performance of dry storage
systems.
The purpose of this notice is to provide the public with an
opportunity to review and provide comments on Draft NUREG-2174,
``Impact of Variation in Environmental Conditions on the Thermal
Performance of Dry Storage Casks.'' Any comments received will be
considered in the final version or subsequent revisions of the draft
NUREG.
Dated at Rockville, Maryland, this 24th day of February, 2015.
For the Nuclear Regulatory Commission.
