Latest Patents

One of his latest patents is a "System and method for plugging the core barrel of a nuclear reactor." This invention presents an improved plugging system designed for chamfered flow ports of small diameters in the core barrel of a pressurized water nuclear reactor. The system features advanced core barrel plugs that are telescopically contractible, facilitating easier installation. It also includes a handling tool equipped with a compact hydraulic ram and a plug-holding cradle, which can be manipulated in the limited access space between the core barrel and thermal shield of the reactor. This design allows for the effective insertion and expansion of the plugs into sealing engagement with the core barrel flow ports.

Another significant patent is the "Support pin system and locking nut retainer." This non-welded fastening system is designed to connect a first structural member, such as a nuclear reactor control rod guide tube flange, to a second structural member, like the nuclear reactor upper core plate. The system includes a support pin and nut, where the first pin portion passes through the first member and has a threaded section that mates with the nut. The design ensures that loads applied transversely to the system are reacted substantially in pure shear through the solid body section of the pin.
