Neutronic Evaluation of Using a Thorium Sulfate Solution in an Aqueous Homogeneous Reactor

چکیده
Radioisotope 99 Mo is one of the most essential radioisotopes in nuclear medicine. Its production an Aqueous Homogeneous Reactor (AHR) could be potentially advantageous compared to traditional technology, based on target irradiation a heterogeneous reactor. An AHR conceptual design using low-enriched uranium for has been studied depth. So far, possibility replacing with non-uranium fuel, specifically mixture 232 Th and 233 U, not evaluated design. Therefore, studies conducted this article aim evaluate neutronic behavior thorium sulfate solution. Here, Th- U composition guarantee ten years operation without refueling, conversion ratio, medical isotopes levels, reactor kinetic parameters were evaluated, computational code MCNP6. It was obtained that 14 % enrichment guarantees refueling. The ratio calculated at 0.14. resulted 24.4 higher fuel than fuel.

Coordination of a uraniumIV sulfate monomer in an aqueous solution and in the solid state.
UraniumIV sulfate in an aqueous solution and the solid state has been investigated with extended X-ray absorption fine structure (EXAFS) and X-ray diffraction (XRD). The coordination polyhedron comprises monodentate sulfate, bidentate sulfate, and water molecules. The coordination modes of sulfate in solution have been determined from the U-S distances with EXAFS. The U-S distance of 3.67 +/- 0...
