  • Publication number: 20200075182
    Abstract: Provided are a nuclear fuel rod for fast reactors that includes a metallic fuel slug coated with a protective coating layer and a fabrication method thereof. The nuclear fuel rod for fast reactors that includes a surface treated metallic fuel slug and a cladding tube according to the present invention has an excellent effect of stabilizing components of the metallic fuel slug and fission products or impurities, because the interdiffusion between the metallic fuel slug and the cladding tube does not occur. Also, since the uniform coating on the surface of the metallic fuel slug may be facilitated and fabrication costs may be significantly reduced in comparison to a typical technique of using a functional material for preventing the interdiffusion at an inner surface of the cladding tube, it may be suitable for fabricating the nuclear fuel rod for fast reactors.

  • Patent number: 10155848
    Abstract: The efficient production of poly(tetramethylene ether) diacetate [PTMEA] or other diesters, from tetrahydrofuran [THF] is obtained utilizing an acid-based catalyst that is based on a morphologically reconfigured and Bronsted acidity enhanced halloysite derived from a preparation method of using naturally occurring halloysites. More specifically, the method relates to morphological modification of the internal pore structure of halloysites via supercritical carbon dioxide treatment directly applied onto the raw halloysite minerals, that yields highly synergistic and reproducible results of elimination of inaccessible and detrimental extra-small pores.
