→ Nuclear Criticality Safety Standards for nuclear materials outside reactor cores

Comments Close:

The U.S. Nuclear Regulatory Commission is issuing for public comment draft regulatory guide DG-3053, “Nuclear Criticality Safety Standards for Nuclear Materials Outside Reactor Cores.” This draft regulatory guide would be published as a revision to Regulatory Guide 3.71. The proposed revision would provide methods that are acceptable to the Nuclear Regulatory Commission 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-8 standards. The revision would also endorse International Organization for Standardization Standard 7753:1987, “Nuclear Energy—Performance and Testing Requirements for Criticality Detection and Alarm Systems.”
