20090135983 | Cross-Section Reducing Isotope System - An isotope production target rod for a power generating nuclear reactor is provided. The isotope production target rod can include at least one rod central body including an outer shell that defines an internal cavity and a plurality of irradiation targets within the internal cavity. The irradiation targets can be positioned in a spatial arrangement utilizing a low nuclear cross-section separating medium to maintain the spatial arrangement. | 05-28-2009 |
20090135987 | Fuel rod designs using internal spacer element and methods of using the same - Example embodiments may include a nuclear fuel rod and/or segment design using fuel element spacers. Fuel element spacers may be placed at intervals within fuel rods and/or segments in order to manipulate operating characteristics of the fuel rods and/or segments and/or decrease consequences of fretting of the fuel rod and/or segment. Example methods may include using fuel rods and/or segments having fuel element spacing elements by adjusting intervals of the spacing elements so as to affect the mechanical, neutronic, and/or thermal properties of the fuel rod and/or segment. | 05-28-2009 |
20090135988 | Fail-Free Fuel Bundle Assembly - A fuel bundle for a nuclear reactor core is provided. The fuel bundle may include a plurality of rods comprised of nuclear fuel rods and/or isotope production rods. Each rod includes a plurality of interconnected rod segments, wherein at least two of the rod segments of at least one rod have different outside diameters. The fuel bundle may additionally include a plurality of rod spacer grids securely retained between axially adjacent, interconnected rod segments. The rod spacer grids interconnected between axially adjacent rod segments form an array of substantially equally spaced rods. The fuel bundle may further include an elongate tubular channel in which the arrayed rods are housed. | 05-28-2009 |
20090135989 | Segmented fuel rod bundle designs using fixed spacer plates - Example embodiments are directed to a fuel rod design using segmented fuel rods that mechanically confine spacer plates to constant axial positions. Example embodiment spacer plates may be placed at axial connection points between fuel rod segments, and, when the fuel rod segments are mated, example embodiment spacer plates may be mechanically held by the mating. | 05-28-2009 |
20090213977 | Apparatuses and methods for production of radioisotopes in nuclear reactor instrumentation tubes - Example embodiments are directed to apparatuses and methods for producing radioisotopes in instrumentation tubes of operating commercial nuclear reactors. Irradiation targets may be inserted and removed from instrumentation tubes during operation and converted to radioisotopes otherwise unavailable from nuclear reactors. Example apparatuses may continuously insert, remove, and store irradiation targets to be converted to useable radioisotopes. | 08-27-2009 |
20100266095 | Burnable Poison Materials and Apparatuses for Nuclear Reactors and Methods of Using the Same - Example embodiments are directed to materials useable as burnable poisons in nuclear reactors, components using the same, and methods of using the same. Example embodiment burnable poison materials produce desired daughter products as they burn out, thereby permitting placement and use for neutronic characteristic improvement and/or neutron flux shielding in locations conventionally barred as uneconomical. Example embodiment burnable poison materials may include natural iridium and enriched iridium-193. Example embodiment components may be fabricated, shaped, and placed to provide desired burnable poison effects in the reactor core in conventional locations and locations not conventionally used due to economic infeasibility. Example methods include use of example embodiment components, including determining locations benefiting from burnable poison effects, fabricating example embodiment components of a desired amount of example embodiment burnable poison materials, placing the example embodiment components, exposing example embodiment components to flux within the operating nuclear reactor, removing and harvesting example embodiment burnable poison components for desired daughter products produced from example embodiment burnable poison materials. | 10-21-2010 |
20130077725 | IRRADIATION TARGET ENCAPSULATION ASSEMBLY AND METHOD OF ASSEMBLY - In one embodiment, an irradiation target encapsulation assembly, includes a container, at least one first irradiation target disposed in the container, at least one second irradiation target disposed in the container, and a positioning structure configured to position the first irradiation target closer to an axial center of the container than the second irradiation target. | 03-28-2013 |
20130223578 | APPARATUSES AND METHODS FOR PRODUCTION OF RADIOISOTOPES IN NUCLEAR REACTOR INSTRUMENTATION TUBES - Example embodiments are directed to apparatuses and methods for producing radioisotopes in instrumentation tubes of operating commercial nuclear reactors. Irradiation targets may be inserted and removed from instrumentation tubes during operation and converted to radioisotopes otherwise unavailable from nuclear reactors. Example apparatuses may continuously insert, remove, and store irradiation targets to be converted to useable radioisotopes. | 08-29-2013 |
