Title: Kouichi Yamane: Innovator in Nuclear Reactor Technology

Introduction

Kouichi Yamane is a notable inventor based in Hitachi, Japan. He has made significant contributions to the field of nuclear reactor technology, holding 2 patents that focus on improving reactor water management and efficiency.

Latest Patents

Yamane's latest patents include a boiling water reactor and its operating method. This innovation features a reactor water clean-up system that utilizes a first filter demineralizer with a filter resin containing an alkali substance, and a second filter demineralizer without it. The reactor water is initially supplied to the first filter during the preoperating test of the nuclear reactor and throughout each fuel cycle up to 2000 EFPH. The alkali substance in the filter resin helps adjust the pH of the reactor water to the weak alkali side, reducing the chromium quantity absorbed in the oxide film of the fuel cladding tube surface. After 2000 EFPH, the reactor water is redirected to the second filter demineralizer. Another patent focuses on reactor water control methods in BWR power plants, which enhance crud deposition on fuel rods to efficiently reduce radioactivity in the reactor water.
