Draft interim staff guidance; request for comment.
The U.S. Nuclear Regulatory Commission (NRC or the Commission) is issuing for public comment Draft Spent Fuel Storage and Transportation Interim Staff Guidance (SFST-ISG), SFST-ISG-8, Revision 3, “Burnup Credit in the Criticality Safety Analyses of PWR Spent Fuel in Transportation and Storage Casks.” This SFST-ISG provides guidance for use by NRC staff when reviewing applications requesting burnup credit in the criticality safety analyses of pressurized water reactor spent nuclear fuel (SNF) in transportation packages and storage casks. The draft SFST-ISG proposes to revise the criticality safety review procedures and acceptance criteria contained in NUREG-1536, Revision 1, “Standard Review Plan for Spent Fuel Dry Storage Systems at a General License Facility,” NUREG-1567, “Standard Review Plan for Spent Fuel Dry Storage Facilities,” and NUREG-1617, “Standard Review Plan for Transportation Packages for Spent Nuclear Fuel.”
Submit comments by June 1, 2012. Comments received after this date will be considered, if it is practical to do so, but the NRC staff is able to ensure consideration only for comments received on or before this date.

B. Submitting Comments
Please include Docket ID NRC-2012-0100 in the subject line of your comment submission, in order to ensure that the NRC is able to make your comment submission available to the public in this docket.
The NRC cautions you not to include identifying or contact information in comment submissions that you do not want to be publicly disclosed. The NRC posts all comment submissions at http://www.regulations.gov as well as entering the comment submissions into ADAMS, and the NRC does not 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 in their comment submissions that they do not want to be publicly disclosed. Your request should state that the NRC will not edit comment submissions to remove such information before making the comment submissions available to the public or entering the comment submissions into ADAMS.
The NRC issues SFST-ISGs to communicate insights and lessons learned and to address emergent issues not covered in SFST Standard Review Plans (SRPs). In this way, the NRC staff and stakeholders may use the guidance in an SFST-ISG document before it is incorporated into a formal SRP revision.
The NRC staff has developed draft SFST-ISG-8, Revision 3 to (a) incorporate the results of burnup credit criticality safety research performed since the last SFST-ISG-8 revision in 2002 into the limits for the licensing basis, (b) provide recommendations regarding advanced isotopic depletion and criticality code validation techniques, (c) provide recommendations regarding credit for fission product neutron absorbing nuclides in the criticality analysis for SNF systems, (d) add a recommendation for an optional misload analysis coupled with additional administrative SNF system loading procedures, in lieu of a direct burnup measurement, and (e) make miscellaneous and editorial changes.
By this action, the NRC is requesting public comments on draft SFST-ISG-8, Revision 3. This SFST-ISG proposes certain revisions to NRC guidance on implementation of the requirements in Title 10, Parts 71 and 72, of the Code of Federal Regulations. The NRC staff will make a final determination regarding issuance of the SFST-ISG after it considers any public comments received in response to this request.
Dated at Rockville, Maryland, this 19th day of April 2012.
For the Nuclear Regulatory Commission.
Brooke D. Poole,
Acting Director, Division of Spent Fuel Storage and Transportation, Office of Nuclear Material Safety and Safeguards.
