摘要： 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 (S100), fabricating example embodiment components of a desired amount of example embodiment burnable poison materials (S110), placing the example embodiment components (S120), exposing example embodiment components to flux within the operating nuclear reactor (S130), removing and harvesting (S140) example embodiment burnable poison components for desired daughter products produced from example embodiment burnable poison materials.

摘要： A method for producing uniform activity targets (600) according to an embodiment of the invention may include arranging a plurality of targets (600) in a holding device (100) having an array of compartments (202), each target (600) being assigned to a compartment (202) based on a known flux of a reactor core so as to facilitate an appropriate exposure of the targets (600) to the flux based on target placement within the array of compartments (202). The holding device (100) may be positioned within the reactor core to irradiate the targets (600). The method may be used to produce brachytherapy and/or radiography targets (e.g., seeds) in a reactor core such that the targets (600) have relatively uniform activity.

摘要： The present invention is directed to the placement of one or more isotope production rods in a fuel bundle. The placement may be based on any one of, or a combination of, numerous factors such as relative location of core-monitoring equipment, the type of radioactive isotope being produced, the half-life or length of decay of the radioactive isotope, the neutron absorption rate of the target isotope to produce the radioactive isotope, the desired specific activity of the radioactive isotope being produced, the amount of neutron flux in different areas of the fuel bundle, the duration that the target isotope/radioactive isotope is expected to remain in the reactor until removed (i.e., harvested), etc.
