On October 03, 2018 (83 FR 49956), the Nuclear Regulatory Commission (NRC) published a notice in the federal register about issuing Revision 3 to Regulatory Guide (RG) 3.71, “Nuclear Criticality Safety Standards for Nuclear Materials Outside Reactor Cores.” Revision 3 endorses guidance in multiple American National Standards Institute/American Nuclear Society (ANSI/ANS)-8 standards, as well as a specific International Organization for Standardization (ISO) Standard. In addition, the scope of this guide is expanded to include packaging and transportation and certain storage facilities because many of the standards are based on broad principles that are not limited solely to fuel processing facilities. Revision 3 to RG 3.71 is available on October 3, 2018.
