Process Optimization in the Chemical Life Cycle of Accelerator-Produced, Low Specific Activity 99Mo

Creator:: Bettinardi, David J.
Abstract:: Global efforts to support non-uranium approaches for 99Mo production, due to the proliferation risks associated with 235U fission-based production methods, have recently taken huge strides towards fruition. Several linear accelerator-based methods are currently in late-stage development that can produce low specific activity 99Mo from enriched 98/100Mo targets. The development of...

The chemistry of acetohydroxamic acid related to nuclear fuel reprocessing

Creator:: Matteson, Brent Searle
Abstract:: Used Nuclear Fuel (UNF) contains transuranic (TRU) elements and numerous fission products as a result of the uranium fission process and neutron activation that occur in commercial light water power reactors. Recent environmental and nuclear proliferation concerns have spawned the development of advanced reprocessing techniques to close the nuclear fuel...

Synthesis and testing of a novel soft donor organic extractant molecule for targeted soft metal extraction from aqueous phases

Creator:: Gullekson, Brian J.
Abstract:: Spent nuclear fuel (SNF) resultant from the generation of nuclear power is a chemically and radiologically diverse system which is advantageous to chemically process prior to geologic disposal. Hydrometallurgy is the primary technology for chemical processing for light water reactor spent fuels, where spent fuel is dissolved in an acid...

Solvent Extraction Behavior of Mixed N, O-Donor Ligands for Separation of Trivalent f-Elements

Creator:: Karslyan, Yana
Abstract:: Nowadays selective separation processes are sought after more than ever before. They are indispensable to meet the growing demand for individual rare earth elements, minor actinides partitioned from fission-produced lanthanides, as well as, overall, more concentrated and high-purity products. This research focuses on such separation techniques as solvent extraction which...

The effects of radiolysis and hydrolysis on the stability of extraction systems for minor actinides

Creator:: Wade, Emily C.
Abstract:: Industrial reprocessing of irradiated nuclear fuel (INF) is one of the most complex procedures performed on a large scale; the process is intricate due to the mix of radionuclides present in INF. As a global trend for nuclear power and reprocessing continues, research is geared toward optimizing the extraction of...

Purification of cyclotron-produced 89Zr for its use in diagnostic radiopharmaceutical labeling

Creator:: Knaus, Clinton W.
Abstract:: Production of 89Zr serves as a crucial preliminary step for exploring Zr-chelates, determining their stability constants, and advancing radiolabeling methodologies for monoclonal antibody based theranostics. 89Zr is typically produced by the irradiation of natural yttrium targets, a process extensively documented in scientific literature. Two primary methods are employed: the 89Y(p,n)89Zr...

Preliminary investigation of X-ray imaging for dose extraction of BANG® polymer gel in intensity modulated radiation therapy

Creator:: Sath, Chhipo
Abstract:: This study investigated gel dosimetry with X-ray CT imaging as a possible means for extracting dose information from a 3D gel dosimeter. Currently Optical CT and MRI are the popular means of dose extraction, but X-ray CT imaging has the advantage of being more convenient and cost effective. The dosimetric...

The kinetic and radiolytic aspects of control of the redox speciation of neptunium in solutions of nitric acid

Creator:: Precek, Martin
Abstract:: Neptunium, with its rich redox chemistry, has a special position in the chemistry of actinides. With a decades-long history of development of aqueous separation methods for used nuclear fuel (UNF), management of neptunium remains an unresolved issue because of its not clearly defined redox speciation. Neptunium is present in two,...

Dissolution of uranium dioxide microspheres in carbonate and hydrogen peroxide solutions

Creator:: Adams, Timothy G.
Abstract:: Uranium dioxide has been used in industry both as a fuel for power reactors and as a target for the production of radioisotopes. One of the most important radioisotopes produced using these targets is molybdenum-99 (Mo-99, 65.94hr half-life), which is the parent isotope to technetium-99m (Tc-99m, 6.01hr half-life), a radioisotope...

Microstructure of radiation damage in the uranium film and its backing materials irradiated with 136 MeV 136Xe+26, Microstructure of radiation damage in the uranium film and its backing materials irradiated with 136 MeV ¹³⁶Xe⁺²⁶

Creator:: Sadi, Supriyadi
Abstract:: Microstructure changes in uranium and uranium/metal alloys due to radiation damage are of great interest in nuclear science and engineering. Titanium has attracted attention because of its similarity to Zr. It has been proposed for use in the second generation of fusion reactors due to its resistance to radiation-induced swelling....
