Design of a neutron irradiation campaign for electron beam welded reactor pressure vessel steel

The objective of this study is to document a neutron irradiation experiment campaign intended to enable evaluation of embrittlement in electron beam (EB) welded SA508, Grade 3 reactor pressure vessel (RPV) steel for small modular reactors. Arc welds in RPVs have historically expe...

Model predictive control with state estimation and reduced-order physics for nuclear reactor operation during unanticipated communication transients

Advanced nuclear reactors are increasingly being designed for remote operation and higher levels of autonomy, particularly for small and microreactor applications where on-site staffing and frequent fuel handling may be impractical. These new operational paradigms would require n...

Linear and Nonlinear Learning from Spectroelectrochemical Data: Interrogation of PLS and CNN Behavior Under Experimental Scarcity

Spectroelectrochemistry (SEC) provides unique information-rich datasets by coupling molecular spectroscopic fingerprints with electrochemical activity. Despite its richness, direct machine-learning (ML) analysis of SEC data under realistic experimental constraints and scarcity re...

The Potential of Operando DRIFT Spectroscopy for Studying Degradation Mechanisms of Metal Oxide‐Based Electrochemical Cells

ABSTRACT High‐temperature electrochemical oxide devices are promising for many applications. These devices are known to be prone to degradation, yet the mechanisms remain poorly understood. In this perspective, we summarize the techniques most used to study degradation in metal o...

Separation and Recovery of High-Purity Dysprosium from Electric Vehicle Scrap Permanent Magnets Using Cyanex 572, a Cationic Extractant in a Membrane Solvent Extraction Process

Abstract Rare earth elements (REEs), especially heavy rare earth elements such as dysprosium (Dy), have gained immense attention globally due to their widespread use in many state-of-the-art technologies. Consequently, demand for REEs is increasing rapidly in comparison to their...
