Title: Shigeru Udono: Innovator in Reactor Control Systems

Introduction

Shigeru Udono is a notable inventor based in Ibaraki, Japan. He has made significant contributions to the field of reactor control systems, holding a total of 2 patents. His work primarily focuses on enhancing the safety and efficiency of boiling water reactors.

Latest Patents

One of Udono's latest patents is a reactor manual control system designed for boiling water reactors. This innovative system controls each control rod hydraulically by driving a solenoid valve. The control system includes an operation control means with a duplicated data processing unit that generates sequence patterns based on the timing of the driving sequence, which is informed by manually provided control information. Additionally, it features a transmission control means that creates a command word for each control rod being controlled, allowing for mutual communication between duplicated data processing units. The system computes the AND logic of the data within a predetermined time difference, and when the computed results coincide, it transmits the selected command word serially. Furthermore, a transmission unit receives the command word, performs protocol conversion, and transmits it to multiple downstream transmission branch units as the control command. Finally, a solenoid valve drive circuit drives the control rod drive unit corresponding to each rod branched from the transmission branch units.
