Latest Patents

Among his latest patents is a groundbreaking treatment method for the internal components of nuclear reactors. This method involves the use of an electroless plating solution that contains an electrical insulating substance, which has a resistivity approximately 100,000 times greater than the structural components of a nuclear power plant. By applying this metal film to the components exposed to reactor water, the electrochemical corrosion potential is significantly reduced, even in the presence of hydrogen in the water.

Another critical patent relates to a reactor water control method for boiling water reactors (BWR) during an operational cycle. This method accelerates the deposition of crud on fuel rods when new fuel rods are loaded. The process targets a predetermined amount of crud deposition, allowing for efficient reduction of radioactivity in the reactor water—especially beneficial for Zr liner type fuel rods, which traditionally face challenges with metal ion deposition.
