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.

Two irradiation tests were conducted in the pressurized water reactor loop of the High Flux Reactor at Petten to compare the low burnup (0.4% fima), high power (35 to 60 kW·m−1) performance of MO2 sphere-pac fuel with the plutonium incorporated only in the large (1000-µm) diameter spheres and that of homogeneously enriched UO2 sphere-pac and pellet fuel The fuel columns in the Zircaloy-4 clad pins were fabricated with a smear density of 87 to 88% of the theoretical UO2 density. Postirradiation examinations showed that fission gas release, axial migration of cesium, and relocation of small (10- to 40-µm) and medium (∼100-µm) diameter spheres were considerably larger in the MO2 sphere-pac pins than in the UO2 sphere-pac pins. Contrary to observations in the pellet pins, no hard mechanical fuel-cladding interaction has been observed in the sphere-pac pins. Although these tests showed the technical feasibility of the inhomogeneous MO2 sphere-pac fuel pin, its further development seems appropriate only in connection with the use of recycle light water reactor fuel.
