Introduction

Ryusuke Kimura is an inventor associated with Hitachi, Japan, and Hitachi-GE Nuclear Energy, Ltd. His patent work includes a gamma scanning apparatus designed to measure gamma-ray emissions from a fuel assembly.

Latest Patents

The available information identifies one patent associated with Kimura: Gamma Scanning Apparatus. The apparatus combines a mechanism for positioning and securing its housing with a mechanism that moves a fuel assembly vertically and rotates it. A gamma-ray detector measures emissions, while a counting circuit records detector output. A data collection, analysis, and control apparatus relates those measurements to the assembly’s movement and rotation.

With the housing and fuel assembly held at a fixed vertical position, the apparatus rotates the assembly through 360 degrees while maintaining its height. During the rotation, the counting circuit measures either the detector’s average count over time or its integrated count over a specified interval. This approach links gamma-ray measurements to the assembly’s angular position.

Career Highlights

Kimura’s documented patent contribution concerns instrumentation and measurement in the nuclear-energy field. The apparatus’s coordinated positioning, rotation, and data analysis are intended to support gamma scanning of fuel assemblies. The supplied information lists 1 patent for him.
