Latest Patents

One of Yasushi Hirano's latest patents involves a novel fuel assembly for nuclear reactors. This invention features a core that includes channel boxes separated by spaces for control rods and a plurality of fuel rods. Notably, at least some of these fuel rods are charged with a uranium-plutonium mixture fuel. The distribution of U-235 enrichment or plutonium concentration is carefully managed along the axial direction of the fuel rods. Additionally, the concentration of a burnable poison within the fuel rod is also distributed axially. The design increases the ratio of the moderator's occupying region relative to the fuel occupying region, allowing for a variable number of fuel rods containing the burnable poison, which can be adjusted based on the total number of fuel rods and their arrangement.
