Proposed rule for more flexible licensing under Part 53 is open for comment
The Nuclear Regulatory Commission has published a proposed rule that has been almost five years in the making: Risk-Informed, Technology-Inclusive Regulatory Framework for Advanced Reactors. The rule, which by law must take its final form before the end of 2027, would let the NRC and license applicants use technology-inclusive approaches and risk-informed, performance-based techniques to effectively license any nuclear technology. This is a departure from two licensing options with light water reactor–specific regulatory requirements that applicants can already choose.

A new model is proposed to predict the formation and influence of channels on the behavior of the debris bed related to the postaccident heat removal situation in fast breeder nuclear reactors cooled by liquid sodium. A two-dimensional dryout numerical prediction based on the spouting occurrence shows a complete agreement with the results of in-pile tests D2, D3, and D4 at Sandia National Laboratories.
