Title: Hiroaki Kagami: Innovator in Nuclear Reactor Technology
Introduction
Hiroaki Kagami is a notable inventor based in Kanagawa-ken, Japan. He has made significant contributions to the field of nuclear reactor technology, particularly through his innovative work on zirconium-based alloys.
Latest Patents
Hiroaki Kagami holds a patent for a non-heat treated zirconium alloy fuel cladding and a method of manufacturing the same. This patent discloses zirconium-based alloys that can be fabricated to form nuclear reactor components, specifically fuel cladding tubes. These alloys exhibit sufficient corrosion resistance and hydrogen absorption characteristics without requiring late-stage α+β or β-quenching processes. The alloys include between about 1.30-1.60 wt % tin, 0.0975-0.15 wt % chromium, 0.16-0.24 wt % iron, and up to about 0.08 wt % nickel. The total content of iron, chromium, and nickel comprises at least about 0.3175 wt % of the alloy. The resulting components demonstrate a surface region with a mean precipitate sizing of between about 50 and 100 nm and a Sigma A of less than about 2×10 hours. The workpiece processing is generally limited to temperatures below 680°C for extrusion and below 625°C for all other operations. This innovation simplifies the fabrication of nuclear reactor components while providing corrosion resistance comparable to conventional alloys.
