Draft regulatory guide; request for comment.
The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment draft regulatory guide (DG), DG-3053, “Nuclear Criticality Safety Standards for Nuclear Materials Outside Reactor Cores.” This DG would be published as Revision 3 to Regulatory Guide (RG) 3.71. The proposed revision would provide methods that are acceptable to the NRC staff for criticality safety standards used with nuclear materials outside reactor cores. The revision would provide up-to-date guidance based on changes to American National Standards Institute/American Nuclear Society (ANSI/ANS)-8 standards. The revision would also endorse International Organization for Standardization (ISO) Standard 7753:1987, “Nuclear Energy—Performance and Testing Requirements for Criticality Detection and Alarm Systems.”
Submit comments by October 23, 2017. Comments received after this date will be considered if it is practical to do so, but the NRC is able to ensure consideration only for comments received on or before this date. Although a time limit is given, comments and suggestions in connection with items for inclusion in guides currently being developed or improvements in all published guides are encouraged at any time.
You may submit comments by any of the following methods:

The NRC cautions you not to include identifying or contact information that you do not want to be publicly disclosed in your comment submission. The NRC posts all comment submissions at http://www.regulations.gov as well as enters the comment submissions into 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. Additional Information
The NRC is issuing for public comment a DG in the NRC's “Regulatory Guide” series. This series was developed to describe and make available to the public information regarding methods that are acceptable to the NRC staff for implementing specific parts of the NRC's regulations, techniques that the staff uses in evaluating specific issues or postulated events, and data that the staff needs in its review of applications for permits and licenses.
The DG, entitled “Nuclear Criticality Safety Standards for Nuclear Materials Outside Reactor Cores,” is a proposed revision temporarily identified by its task number, DG-3053. The DG-3053 is proposed Revision 3 of RG 3.71, “Nuclear Criticality Safety Standards for Nuclear Materials outside Reactor Cores.” The NRC initially issued RG 3.71 in 1998, and it was revised in 2005 and again in 2010. The three previous versions of RG 3.71 endorsed specific safety standards developed by ANSI/ANS-8 to provide guidance, criteria, and best practices for use in preventing and mitigating criticality accidents during operations that involve handling, processing, storing, or transporting special nuclear material at fuel and material facilities (or a combination of these activities). The proposed Revision 3 would revise the RG based on changes to ANSI/ANS-8 standards, with certain exceptions and clarifications. The revision would also consolidate and replace a number of earlier NRC RGs, thereby incorporating all of the relevant guidance in a single document. This revision would also endorse International Organization for Standardization (ISO) Standard 7753:1987, “Nuclear Energy—Performance and Testing Requirements for Criticality Detection and Alarm Systems.” In addition, the scope of this revision is expanded beyond part 70 of title 10 of the Code of Federal Regulations (10 CFR), fuel facilities to include transportation and storage facilities under parts 71 and 72.
This DG-3053 would update RG 3.71 based on changes to ANSI/ANS standards, as well as endorsing an ISO standard and expanding the scope of the RG to include 10 CFR part 71 and part 72 licensees. Issuance of DG-3053 would not constitute backfitting under 10 CFR part 70 or part 72. As discussed in the “Implementation” section of this DG, the NRC has no current intention to impose the DG on current holders of 10 CFR part 70 or part 72 licenses. The DG could be applied to applications for licenses issued under 10 CFR part 70 or part 72 or amendments thereto. Such action would not constitute backfitting as defined in 10 CFR 70.76 or 10 CFR 72.62, inasmuch as such applicants are not within the scope of entities protected by 10 CFR 70.76 or 10 CFR 72.62.
