NRC proposes security regulation changes
In 2025, President Trump issued Executive Order 14300, “‘Ordering the Reform of the Nuclear Regulatory Commission,” which directs the NRC to conduct a sweeping, multifaceted overhaul of its structure, culture, and regulations with the aim of facilitating increased deployment of new nuclear technologies and capacity.

Solid D-T fuel smoothly layered on the interior of spherical capsules is required for all inertial confinement fusion ignition target designs. One process for forming these layers, beta-layering, has been studied in surrogate geometries such as open cylinders or tori to allow accurate characterization of the DT surfaces. We present the first results from beta layering in 1 mm spherical containers, such as will be used in upcoming Omega experiments. These results are also directly relevant to ignition capsules for the National Ignition Facility. We find that layers can form with roughness as small as 1.2 microns rms, and that results are strongly dependent upon freezing rate as well as layer thickness.
