    摘要: A method of aligning a nuclear fuel bundle and handling selected fuel rods within the fuel bundle located in a spent fuel pool of a nuclear power plant. The bundle includes water rods, full-length and part-length fuel rods extending through a plurality of fuel spacers provided between top and bottom ends of the bundle, each spacer having a plurality of cells accommodating corresponding fuel and water rods. The method includes insertion of a rod grapple tool into a top end of a fuel bundle and down to a desired location within the bundle. A guide pin retrieval tool inserts into a side of the fuel bundle to remove a guide pin from a distal end of a gripper of the rod grapple tool, allowing the guide pin retrieval tool to grip a part-length fuel rod within the fuel bundle.

    摘要: Fuel spacers include at least one specialized bathtub on an outer perimeter band. Specialized bathtubs include an elastic resistive extension and a corresponding deflection limiter on a same outer face of the perimeter band. The elastic resistive extension provides flexible resistance to the channel, and the deflection limiter provides rigid movement limitation beyond a particular threshold between channel and spacer. The positioning, spring constant, length, number, and other properties of the specialized bathtub can be chosen based on the desired fuel assembly properties and expected transverse loads in fuel shipping and operation against which specialized bathtubs resiliently protect. The specialized bathtubs can be formed from a simplified stamp operation out of the perimeter band. Bathtubs can be placed on any position(s) on the perimeter band of example embodiment spacers used in nuclear fuel assemblies.

    摘要: Provided is an isotope delivery system and a method for irradiating a target and delivering the target to an extraction point. The isotope delivery system may include a cable including at least one target for irradiation, a drive system configured for moving the cable, and a first guide configured to guide the cable for insertion and extraction from a nuclear reactor. The method for irradiating a target and delivering a target may include pushing a cable with an attached target through a first guide and into a nuclear reactor using a drive system, irradiating the target in the nuclear reactor, pulling the cable with the attached irradiated target towards the drive system, pushing the cable with the irradiated target towards a loading/unloading area using the drive system, and placing the irradiated target into a transfer cask, wherein the cable is pulled and pushed by the drive system.
