Data on Nuclear Materials Discussed by R.D. Hunt and Colleagues

June 20, 2014

By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Nuclear Materials. According to news reporting from Dayton, Ohio, by NewsRx journalists, research stated, "The US Department of Energy is considering a new nuclear fuel that would be less susceptible to ruptures during a loss-of-coolant accident. The fuel would consist of tristructural isotropic coated particles with dense uranium nitride (UN) kernels with diameters of 650 or 800 gm."

The news correspondents obtained a quote from the research, "The objectives of this effort are to make uranium oxide microspheres with adequately dispersed carbon nanoparticles and to convert these microspheres into UN spheres, which could be then sintered into kernels. Recent improvements to the internal gelation process were successfully applied to the production of uranium gel spheres with different concentrations of carbon black. After the spheres were washed and dried, a simple two-step heat profile was used to produce porous microspheres with a chemical composition of UC0.07-0.10N0.90-0.93."

According to the news reporters, the research concluded: "The first step involved heating the microspheres to 2023 K in a vacuum, and in the second step, the microspheres were held at 1873 K for 6 h in flowing nitrogen."
