Latest Patents

Yooko Ishibashi holds a patent for a fuel assembly that comprises a plurality of fuel rods. This assembly features fuel rods containing a burnable poison element with a smaller neutron absorption cross-section, such as boron, positioned in regions of soft neutron energy spectrum and large thermal neutron flux. Additionally, it includes fuel rods with a burnable poison element that has a larger neutron absorption cross-section, like gadolinium, as well as fuel rods without such elements in other regions of average neutron energy spectrum. This design ensures a flat fuel rod power distribution throughout the fuel's lifetime, even with uniform uranium enrichment distribution, while reducing parasitic neutron absorption by gadolinium. This results in higher burnup and lower fuel cycle costs.
