Title: Hiroshi Akamatsu: Innovator in Radioactive Material Storage Solutions
Introduction
Hiroshi Akamatsu is a notable inventor based in Takasago, Japan. He has made significant contributions to the field of radioactive material storage, holding 2 patents that showcase his innovative approach to safety and efficiency.
Latest Patents
One of his latest patents is a transport/storage cask for radioactive material. This cask features an inner shell, an outer shell, and both a circular gamma ray shielding layer and a circular neutron shielding layer positioned between the inner and outer shells. The gamma ray shielding layer is constructed by aligning multiple gamma ray shielding blocks made of lead in a block shape around the circumference. Additionally, the entire gamma ray shielding block in the axial direction is encased in a copper tube, which has a higher elasticity limit than the gamma ray shielding block. This design ensures that the gamma ray shielding layer, composed of lead or a lead alloy, remains resistant to deformation. Another patent involves a cask for radioactive material that includes a single gamma ray and neutron shielding layer on the exterior of the vessel body. This shielding layer is made from a compact mixture of lead and a metal hydride, providing an excellent shielding effect based on the balance of radiation source intensity between gamma rays and neutrons, while also allowing for a more compact design.
