چکیده
The studies summarized in this paper aims to predict the steady state operation of a low-enriched uranium fuel ARGUS type aqueous homogeneous reactor for producing 99Mo meet domestic demand Brazil through coupled multi-physics (Neutronics + Thermal-hydraulics) evaluation. evaluation included aspects related neutronic behavior such as fission induced energy deposition profile, medical isotopes production; and thermal-hydraulic temperature, velocities gas volume fraction profiles. methodology followed multi-scale coupling codes (MCNP ANSYS-CFX), discussed detail paper, represent one main outcomes current study. was tested two different operating configurations reactor, original high-enriched configuration used since 1981, new after conversion process during 2012-2014. calculations carried out showed that studied configuration, is able produce 246.5 six days Curie cycles five days. Which equivalent more than third estimated Brazilian 2025.
