Latest Patents

One of Kawai's latest patents is focused on a fuel assembly for nuclear reactor core structures with zones of varying enrichment. This innovative design incorporates two types of fuel assemblies: the first type contains both fissile material and gadolinium, while the second type contains only fissile material. The ratio of the first to the second fuel assemblies is strategically selected to be 1:3. Additionally, the enrichment of the fissile material is greater at the upper part of the reactor core compared to the lower part. The fuel assembly design includes first fuel rods that contain both fissile material and gadolinium, as well as second fuel rods that contain only the fissile material. The number of first fuel rods and the concentration of gadolinium are proportionate to the power density at various positions within the reactor core.
