Title: Masayuki Nishino: Innovator in Nuclear Reactor Maintenance
Introduction
Masayuki Nishino is a notable inventor based in Hitachinaka, Japan. He has made significant contributions to the field of nuclear reactor maintenance, holding a total of 2 patents. His work focuses on enhancing the safety and efficiency of structural members within nuclear pressure vessels.
Latest Patents
Nishino's latest patents include a "Preventive maintenance apparatus for structural members in a nuclear pressure vessel." This invention outlines a method for performing maintenance on structural members inside a reactor pressure vessel. The process involves lowering an annular guide rail until it rests on an upper flange of a core shroud. The guide rail is detachably mounted to a first lug on the core shroud. A discharging nozzle is positioned to add compressive remaining stress to the core shroud's surface. This is achieved by moving the nozzle in both radial and axial directions, utilizing a discharging nozzle moving apparatus mounted on a turntable that revolves on the guide rail.
Another patent by Nishino is also titled "Preventive maintenance apparatus for structural members inside a nuclear reactor pressure vessel." This apparatus features a ring-shaped guide rail with multiple lugs that engage with guide rods on the reactor pressure vessel's inner surface. A turntable rotates on the guide rail, and discharging nozzle moving apparatuses are placed on the turntable to add compressive remaining stress to both the outer and inner surfaces of the core shroud.
