Draft NUREG; request for public comment.
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.
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.
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:
