Latest Patents

James M Gehr holds a patent for a method and apparatus for high pressure laser welding of nuclear fuel rods. This innovative process enables seam welding of a nuclear fuel rod at hyperbaric pressure. The method involves an automatic process where a loaded fuel rod and an upper end plug are mated within a sealable weld box. The pressure within the weld box is controlled relative to the pressure within the fuel rod, allowing a laser assembly to weld the seam at hyperbaric pressure. Additionally, helium flows through a laser window nozzle during welding to prevent soot contamination of the laser window glass and to avoid the formation of ionic plasma. This advancement reduces the upper end plug fuel rod welding operation to a single step and eliminates inspection-related tasks concerning a sealed hole.
