AI/ML for Automated Critical Materials Resource Mapping

Ahamed – INL R&D Staff Scientist

Research Overview

Efficient exploration and development of critical mineral resources increasingly depend on integrating large volumes of geologic and geophysical data. Traditional log‑analysis workflows for solution‑mined deposits require detailed interpretation of lithology, stratigraphic boundaries, fluid‑flow‑controlled alteration zones, and grade‑related signals. These processes are often labor‑intensive and subject to interpreter variability.

This project seeks to apply modern machine learning methodologies to automate essential components of mineral resource mapping. Students will work with representative geophysical and lithologic datasets to:

  • Clean and preprocess well‑log data (e.g., resistivity, natural gamma, spontaneous potential)
  • Correct depth misalignments between lithologic and geophysical logs
  • Build ML models for lithology prediction, stratigraphic correlation, and geologic zonation analysis
  • Investigate pattern recognition methods to identify alteration fronts and mineralization indicators
  • Explore workflow expansion using physics‑informed ML or sparse sensing approaches to improve mapping under limited‑data conditions

The overarching goal is to develop scalable data‑driven methods that enhance subsurface interpretation for critical materials and solution‑mining applications.

Student Research Experience

Students will engage in interdisciplinary work spanning geoscience, machine learning, and data engineering. Activities include:

  • Data Integration & Preprocessing – preparing and aligning multi‑source well‑log datasets, correcting sample‑lag effects, and constructing geologically meaningful features.
  • Machine Learning Model Development – implementing algorithms such as PCA, dynamic time warping, tree‑based models, gradient‑boosting methods, and neural networks to support automated interpretation.
  • Geologic Interpretation – learning how lithologic variation, stratigraphic architecture, and fluid‑alteration signatures relate to mineral resource distribution within solution‑mined systems.
  • Model Evaluation & Visualization – generating correlation panels, prediction plots, and zonation maps to assess machine‑learning results in a geologic context.

Students will collaborate with INL staff and gain experience applying AI/ML techniques to real‑world subsurface problems relevant to critical materials, energy security, and advanced resource extraction technologies.

  • Self-Healing Materials for Extreme Environments

    K.S. Raja – University of Idaho

    Research Overview

    Nuclear and power plant components are exposed to aggressive service conditions — high temperatures, high stresses, irradiation, and corrosion — which lead to damage accumulation and restricted service lifetime. If structural materials can self-heal microscopic damages induced by irradiation, creep, and other degradation mechanisms, their lifetime can be extended considerably.

    In this research, metal-core oxide-shell (MCOS) nano-capsules will be prepared by controlled oxidation of nano-particles of low melting point metals such as Sn and Zn. Using a powder metallurgy approach, the MCOS nano-capsules will be distributed in a metal matrix (preferably low-carbon steel). Test samples will be prepared using different manufacturing techniques, and self-healing behavior will be demonstrated by conducting tensile testing at high temperatures.

    Student Research Experience

    Students will be trained in materials processing, advanced manufacturing, materials characterization, and materials testing. Processing techniques include controlled oxidation of nanomaterials, high-energy ball milling, and high-pressure compaction. Manufacturing processes include conventional sintering and laser powder bed fusion.

    Material characterization techniques include optical and electron microscopy, and confocal Raman spectroscopy. Testing techniques are micro-hardness survey and tensile testing at different temperatures. Students will be trained by working with graduate students and faculty, will learn to critically analyze experimental data using a statistical approach, write reports, and participate in weekly research progress meetings.

  • Classical Molecular Dynamics Simulations of Nuclear Materials

    Russell – University of Idaho

    Research Overview

    Atomistic simulations are increasingly valuable for industrial needs to predict thermodynamic and kinetic properties of systems at the nanoscale. Design and fitting of interatomic potentials for application to nuclear materials is also an area of fundamental interest. Simulation and modeling can provide understanding of mechanisms that occur far from equilibrium, which can be difficult to directly observe by experiment.

    Accurate prediction of melting temperature and elastic properties at finite temperatures are challenging because interatomic potentials are typically fit to zero temperature electronic structure results. New interatomic potentials based on explainable artificial intelligence concepts are needed that combine physics based functional forms with advanced machine learning techniques to fit parameter sets.

    Student Research Experience

    Working in collaboration with INL’s Collaborative Computing Center, students will learn fundamentals of computational atomistic simulation and modeling. Students will obtain a user account on the NSF ACCESS cyberinfrastructure program and utilize the Bridges-2 supercomputer hosted by the Pittsburgh Supercomputing Center (PSC).

    Students will learn to use high performance computers, the LAMMPS code, visualization with VMD code, scripting, and post processing techniques. They will also learn fundamentals of machine learning to fit parameters and the physics behind interatomic potential design. Advanced students may learn programming languages and parallel computing techniques.

  • Effect of Pressure Resistance Welded Molybdenum Alloy’s Response to Helium Ion Irradiation

    Charit – University of Idaho

    Research Overview

    The overarching goal is to explore and understand the irradiation response of pressure resistance welding (PRW) technology on two molybdenum-based materials: commercially pure molybdenum and an oxide (La₂O₃) dispersion strengthened molybdenum alloy, MoLa. The project aims to understand the effect of helium ion irradiation on the microstructural, microchemical and mechanical properties of these materials.

    There has been significant interest in the potential use of molybdenum-based materials among high melting refractory metals/alloys to produce fuel elements for the nuclear thermal rocket engine as well as accident-tolerant fuel cladding applications in advanced light water reactors. The benefits of molybdenum include its high melting point, high thermal conductivity, elevated temperature mechanical properties, and excellent corrosion resistance against liquid metals and aggressive environments.

    Student Research Experience

    The student will have the unique opportunity to learn about the potential use of refractory metals in terrestrial and extra-terrestrial nuclear reactors, and will participate in hands-on characterization of ion irradiated samples and data analysis. They will gain hands-on experience in scanning electron microscopy, energy dispersive spectroscopy and nanoindentation during the project period.

    They will also have the opportunity to observe operation of a high resolution transmission electron microscope by an instrument scientist. Near the end of the project, the student will present findings in microstructure-properties correlations via a presentation.
