Paper Abstract

Pulsed laser drilling and welding of nuclear reactor fuel rods has been demonstrated to be a simple and reliable process for injecting helium into fuel rods at specified pressures and providing an absolute seal. Fuel rods can be pressurized to high pressures, if required, with tight pressure tolerances. The accuracy and reliability of the laser pressurization process represents an attractive technology. The capabilities and limitations of the laser pressurization process are discussed as well as the station design for efficiently pressurizing production quantities of fuel rods. Production welding experience of over 100,000 nuclear reactor fuel rods will be discussed.
