Xe Bubble Re-solution Rates in U-10Mo Fuel Quantified via BCA and MD Simulations
BCA and MD simulations quantify Xe gas bubble re-solution in U-10Mo nuclear fuel, driven by fission fragment nuclear stopping while electronic stopping contributes negligibly. Re-solution rates range from 4.4e-26 m³/fission for large bubbles to 8.8e-25 m³/fission for small ones at equilibrium pressu…
ELECTRAFI Achieves State-of-the-Art Periodic Charge Density Prediction with 633x Speedup via Analytic Gaussian Transforms
ELECTRAFI models periodic charge densities in crystals using anisotropic Gaussians in real space, leveraging closed-form Fourier transforms and Poisson summation for analytic plane-wave coefficients.
