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 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 NaI(Tl)-based in-line enrichment monitor has been developed for the gas-phase UF6 feed stream of an enrichment plant to provide real-time material-accountancy and/or containment-surveillance data. The method has produced assay results that are independent of operating UF6 pressure, with an assay accuracy of better than 1% (1σ) relative over the range of UF6 enrichments of 0.72 to 5.4 at.%. For 1.0%-enriched UF6 at 700 Torr, a 0.74% relative precision was obtained for a 1000-s counting time. As a result of these measurements, an in-line gas-phase enrichment monitor has been installed in the Paducah-product feed line of the Oak Ridge Gaseous Diffusion Plant for field test and evaluation.
