Algorithms for TRISO Fuel Identification Based on X-ray CT Validated on Tungsten-Carbide Compacts
Ming Fang, Angela Di Fulvio
Tristructural-isotropic (TRISO) fuel is one of the most mature fuel types for candidate advanced reactor types under development. TRISO-fuel pebbles flow continuously through the r…
Enabling PSD-capability for a High-density Channel Imager
Ming Fang, Satwik Pani, Angela Di Fulvio
Pulse shape discrimination (PSD) is crucial for non-proliferation and security applications, where fast neutrons need to be identified and measured in the presence of a strong gamm…
Neutron Tomography of Spent Fuel Casks
Zhihua Liua, Ming Fang, Jon George +2
Dry casks for spent nuclear fuel (SNF) ensure the safe storage of SNF and provide radiation shielding. However, the presence of the thick casks encompassing several layers of steel…
A Hierarchical Bayesian Approach to Neutron Spectrum Unfolding with Organic Scintillators
Haonan Zhu, Yoann Altmann, Angela Di Fulvioand Stephen McLaughlin +2
We propose a hierarchical Bayesian model and state-of-art Monte Carlo sampling method to solve the unfolding problem, i.e., to estimate the spectrum of an unknown neutron source fr…
Positron Annihilation Lifetime Spectroscopy Using Fast Scintillators and Digital Electronics
Ming Fang, Nathan Bartholomew, Angela Di Fulvio
Positron Annihilation Lifetime Spectroscopy (PALS) is a non-destructive radiological technique widely used in material science studies. PALS typically relies on an analog coinciden…
