Abstract: A transition piece for joining heat pipe segments in a joining process is provided. The transition piece comprises a head section, a body section, a tail section and alignment tabs configured to facilitate a rotational alignment of an end of the body section and an end of a heat pipe segment during the joining process. The body section comprises a wick and an outer wall. Each of the alignment tabs comprises an end portion axially extending away from the body section. The body section and the alignment tabs are configured as an integral structure. A method for producing a transition piece of a heat pipe and a method for joining segments of a heat pipe are also provided.

Abstract: Disclosed is nuclear reactor fuel rod for use in a nuclear reactor. The nuclear reactor fuel rod comprises a sleeve defining a longitudinal axis. The sleeve includes a first end portion and a second end portion. The nuclear reactor fuel rod further includes a first end cap mechanically coupled to the first end portion of the sleeve and a second end cap mechanically coupled to the second end portion of the sleeve. The second end cap is configured to slide along the longitudinal axis relative to the sleeve. The nuclear reactor fuel rod further includes a fuel compact located inside of the sleeve between the first end cap and the second end cap.

Abstract: A device for thermal management of an electronic component includes an inner shell dimensioned to house an electrical circuit and a thermally conductive metal outer shell. The metal outer shell has a thickness less than 6.3246 mm; a first closed end having a first diameter and dimensioned to support an electronic component operably connected to the electrical circuit; and a second end having a second diameter, wherein the first diameter is greater than the second diameter. The inner shell is at least partially within the outer shell. The outer shell is comprised of a single metal sheet. The thinnest portion of the outer metal shell is less than or equal to 0.75 times the thickest portion of the outer metal shell.

Abstract: This invention discloses a method for calculating gripper trajectories in forming equipment. The method utilizes a computer aided design (CAD) or a computer aided engineering (CAE) computer program to calculate the appropriate location, speed, controller commands, and trajectory for each gripper used during a forming process.
