Title: Koichi Ohtomi: Innovator in Nuclear Reactor Technology
Introduction
Koichi Ohtomi is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the field of nuclear reactor technology, holding a total of 2 patents. His work focuses on enhancing the efficiency and safety of nuclear reactors.
Latest Patents
Ohtomi's latest patents include an innovative internal pump for nuclear reactors. This internal pump features a pump shaft connected to a motor, which rotatably passes through the bottom of a nuclear reactor pressure vessel. An impeller is fitted to the front end of the pump shaft, and a diffuser is positioned downstream of the impeller. The design includes a purge water passage that communicates with the inside of the reactor pressure vessel, along with a purge water supply device. Additionally, the pump incorporates a clad dropping preventive device to trap any clad coming from the reactor pressure vessel, ensuring safety and efficiency.
Another significant patent is a device for measuring the recirculating flow rate in a nuclear reactor. This device includes a flow passage resisting device that creates a pressure difference in the primary coolant flow. Detectors are placed at both the upstream and downstream sides to measure this pressure difference. The detected pressure difference is converted into an electric signal, which is then used to compute the recirculating flow rate of the primary coolant.
