Title: Akira Oda: Innovator in Radioactive Waste Treatment
Introduction
Akira Oda is a notable inventor based in Hitachi, Japan. He has made significant contributions to the field of radioactive waste treatment, holding a total of 4 patents. His innovative approaches aim to enhance the efficiency and safety of waste management processes.
Latest Patents
One of Akira Oda's latest patents is a process and system for the treatment of radioactive waste. This system involves a treatment process for radioactive waste solutions, including sodium sulfate generated from boiling water type nuclear reactors. The waste solution is fed into a thin film evaporator, where it is evaporated and transformed into powder. The precipitated solid is wiped by rotating wiper blades and removed as radioactive solid powder. The rotor's rotational speed is controlled to minimize wear on the wiper blades, thereby improving the system's longevity.
Another significant patent is the rotary vane type evaporator. This device features a cylindrical vessel and a rotor that rotates within it. The rotor includes vane supports fixed to a shaft, with vanes that are pivotally mounted. Each vane is equipped with a balance weight that maintains a constant pressing force against the vessel's inner surface, regardless of wear. This design helps to uniformize the wear of the vane shoes, reducing the frequency of interruptions for maintenance and enhancing the operational efficiency of the evaporator.
