Implementation and testing of the on-the-fly thermal scattering Monte Carlo sampling method for graphite and light water in MCNP6

Journal Article Pavlou, Andrew T. ; Ji, Wei ; Brown, Forrest B. - Annals of Nuclear Energy (Oxford)

Here, a proper treatment of thermal neutron scattering requires accounting for chemical binding through a scattering law S(α,β,T). Monte Carlo codes sample the secondary neutron energy and angle after a thermal scattering event from probability tables generated from S(α,β,T) tables at discrete temperatures, requiring a large amount of data for multiscale and multiphysics problems with detailed temperature gradients. We have previously developed a method to handle this temperature dependence on-the-fly during the Monte Carlo random walk using polynomial expansions in 1/T to directly sample the secondary energy and angle. In this paper, the on-the-fly method is implemented into MCNP6 andmore »« less

Effect of Metallic Li on the Corrosion Behavior of Inconel 625 in Molten LiCl-Li₂O-Li

Journal Article Phillips, William ; Karmiol, Zachary ; Chidambaram, Dev - Journal of the Electrochemical Society

The corrosion behavior of Inconel 625 in molten LiCl solutions maintained at 650°C and containing various quantities of Li₂O and metallic Li was studied for possible application in the electroreduction of used oxide-based nuclear fuel. This study focusses on the morphological and elemental changes on the surface of the samples with an emphasis on cross-sectional analyses conducted using focused ion beam microscopy. In the absence of metallic Li, a stable oxide film is formed that limits the corrosion of the base material to 0.07mm/year. However, in the presence of metallic Li, the formation of this film is impeded, resulting inmore »« less

Effect of Metallic Li on the Surface Chemistry of Inconel 625 Exposed to Molten LiCl-Li₂O-Li

Journal Article Phillips, William ; Chidambaram, Dev - Journal of the Electrochemical Society

This study explores the surface chemistry of Inconel 625 samples exposed to molten LiCl-Li₂O-Li solutions at 650°C for 500 and 1000hr and aims to understand the effect of solvated Li on corrosion behavior in molten LiCl-Li₂O-Li. The surfaces of Inconel 625 samples were analyzed using X-ray diffraction, Raman spectroscopy, and X-ray photoelectron spectroscopy. The oxide films formed on the surface of the samples in the absence of Li is composed of LiCrO₂, with small contributions of Li₂CrO₄ and NiFexCr₂-xO₄. The presence of Li was observed to destabilize these compounds, resulting in a primarily metallic surface with trace amounts of oxidizedmore »« less

Multi-modal tomographic imaging system for poolside characterization of nuclear test fuels: Design considerations and studies

Journal Article Kilby, Seth ; Fletcher, Jack ; Avachat, Ashish ; ... - Nuclear Instruments and Methods in Physics Research. Section A, Accelerators, Spectrometers, Detectors and Associated Equipment

Testing and qualification of advanced nuclear fuels involves an iterative process of prototyping, in-pile irradiation testing, and in-situ or ex-situ examination. Fuel restructuring and fission product migration during burnup are among the most important aspects of fuel evolution that affect several important performance characteristics such as heat removal, accident tolerance, and fission product retention. Pool-side non-destructive characterization techniques provide fuel developers with tools to understand fuel evolution at different points of burnup. A design for a compact, submersible, and multi-modal gamma-ray tomography system for imaging irradiated nuclear fuel is presented here. Detector selection, collimator geometry and fabrication, mechanical design, imagingmore »« less

Corrosion of Additively Manufactured CoCrFeMnNi High Entropy Alloy in Molten NaNO ₃ -KNO ₃

Journal Article Moon, Jeremy T. ; Schindelholz, Eric J. ; Melia, Michael A. ; ... - Journal of the Electrochemical Society (Online)

Exposure testing was performed on CoCrFeMnNi equiatomic high entropy alloy (HEA) produced via directed energy deposition additive manufacturing in NaNO₃-KNO₃ (60–40 wt%) molten salt at 500 °C for 50 h to evaluate the corrosion performance and oxide film chemistry of the HEA. Potentiodynamic electrochemical corrosion testing, scanning electron microscopy, focused ion beam milling coupled with energy dispersive spectroscopy, Raman spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and inductively coupled plasma optical emission spectroscopy were used to analyze the corrosion behavior and chemistry of the HEA/nitrate molten salt system. The CoCrFeMnNi HEA exhibited a higher passive current density during potentiodynamic polarization testingmore »« less
