NUCLEAR REGULATORY COMMISSION

[NRC-2012-0250]


Computational Fluid Dynamics Best Practice Guidelines for Dry 
Cask Applications

AGENCY: Nuclear Regulatory Commission.

ACTION: Draft NUREG; request for public comment.

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

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC or the Commission) 
is requesting public comments on draft NUREG-2152, ``Computational 
Fluid Dynamics Best Practice Guidelines for Dry Cask Applications.'' 
The draft NUREG-2152 report provides best practice guidelines for 
undertaking simulations used to evaluate the thermal response of dry 
casks. Dry cask applications include transfer, transport, and storage. 
First, the different sources of errors and uncertainties known to occur 
in numerical simulation results are listed and defined. The sources of 
error that can be controlled and quantified by the user are then 
discussed in detail, and best practice guidelines for their reduction 
and quantification are given. These best practice guidelines are based 
on available guidelines as much as possible.

DATES: Comments may be submitted by December 24, 2012. 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 on or before this date.

ADDRESSES: You may access information and comment submissions related 
to this document, which the NRC possesses and are publically available, 
by searching on http://www.regulations.gov under Docket ID NRC-2012-
0250. You may submit comments by any of the following methods:
