摘要： A system for storing nuclear fuel, the system including a storage rack and a bearing pad. The storage rack includes an array of cells, each cell configured to receive and store nuclear fuel rods, a base plate configured to support the array of cells, and a support structure configured to support the base plate and to allow cooling fluid to circulate under and up through apertures in the base plate. The bearing pad is coupled to the support structure and is configured to limit lateral movement of the storage rack independent from lateral movement of the bearing pad. The base plate defines a base plate profile in a horizontal plane of the base plate, and the bearing pad defines a bearing pad profile in the horizontal plane of the base plate, wherein the bearing pad profile extends outside of the base plate profile.

摘要： A system, method and apparatus for providing radiation shielding to a ventilated cask for holding high level radioactive materials. In one aspect, the tubular shell is positioned to circumferentially surround the cask so that an annular gap exists between the tubular shell and a sidewall of the cask. The tubular shell includes a first air flow inlet and a second air flow inlet. An air flow barrier is placed within the annular gap, separating the annular gap into a first chamber and a second chamber. A first air flow into the first air flow inlet passes through the first chamber and into the inlet vent of the cask, a second air flow into the second air flow inlet passes through the second chamber and to an opening at the top end of the tubular shell, and the air flow barrier prohibits cross-flow of air between the first and second chambers.

摘要： A method and associated system for joining workpieces formed of neutron absorbing materials. The method includes positioning first and second workpieces together to form a joint, heating the first and second workpieces at the joint to a plastic condition, intermingling plastic material from the first and second workpieces together at the joint, and cooling the intermingled plastic material to a solid state forming a welded fusion zone comprised of material from the first and second metal matrix composite workpieces. The workpiece material at the joint is not melted by the heating. The heating may be perforated by frictionally heating the materials with a rotary tool, in one non-limiting embodiment, the neutron absorbing workpieces may be formed of metal matrix composites comprising aluminum or aluminum alloy and boron carbide.
