With a total of two patents to his name, his innovations focus on enhancing the manufacturing processes of nuclear fuel rods, ensuring both efficiency and safety.

Latest Patents

Sziemkiewicz's latest inventions include a high-pressure laser welding method specifically designed for nuclear fuel rods. This method allows for the seam welding of a nuclear fuel rod at hyperbaric pressure, where an automatic process mates a loaded fuel rod and an upper end plug within a sealable weld box. By controlling the pressure in the weld box relative to the fuel rod, a sophisticated laser assembly seamlessly welds the seam under hyperbaric conditions. Additionally, a unique feature of this apparatus involves helium flowing through a laser window nozzle during welding, which prevents contamination and formation of ionic plasma, making the process more reliable.

Another notable patent involves an automated final welding apparatus for assembling and welding end plugs to nuclear fuel-loaded cladding tubes. This apparatus includes various stations, such as a check station for verifying the presence of a plenum spring and a seam welding station where the final end plug is welded onto the cladding tube. This automated process enhances the efficiency of assembling nuclear fuel rods by incorporating rigorous inspection procedures to sort finished products into accepted and rejected lots based on helium leakage checks.
