Understanding Chemical Short-Range Order in CoNiV via Mode Analysis
Jilang Miao, Miaomiao Jin
We analyze chemical short-range order in equiatomic fcc NiCoV using molecular-dynamics snapshots generated with a machine-learned interatomic potential. Radial distribution functio…
Demonstrating Quadratic Monte Carlo Speedup via Quantum Amplitude Estimation: Nuclear Engineering Examples
Jilang Miao, Miaomiao Jin, Akira Sone
We demonstrate quantum amplitude estimation (QAE) as a route to quadratic speedup for Monte Carlo-type expectation values in nuclear engineering. Using QPE-based QAE, we study two…
Anomalous Ionic Conductivity along the Coherent 3 Grain Boundary in ThO2
Miaomiao Jin, Jilang Miao, Marat Khafizov +3
Understanding oxygen diffusion along grain boundaries (GBs) is critical for controlling ionic conductivity in oxide ceramics. GBs are typically thought to enhance ionic transport d…
Understanding the Sampling Algorithm for Watt Spectrum
Jilang Miao, Miaomiao Jin
We provide details in understanding the Watt spectrum sampling method. The algorithm is given in "R12" from "3rd Monte Carlo Sampler" without detailed derivation. We rederive the a…
Legendre Expansion for Scattering Anisotropy in Analytical 1D Multigroup Equations
Jilang Miao, Miaomiao Jin
We demonstrate the scattering anisotropy treatment of the previously developed analytical solution for 1D multigroup equations.
Coarse Mesh Iteration Approach for Analytical 1D Multigroup Eigenvalue Problems
Jilang Miao, Miaomiao Jin
This paper extends the fixed source capability of analytical 1D multigroup equations to solve eigenvalue problems on coarse mesh.
Developing an Analytical Fixed Source Solver for the 1D Multigroup Equations
Jilang Miao, Miaomiao Jin
We extend the analytical multigroup method to solve 1D fixed source problems. The fixed source solver is applied in power iteration of eigenvalue problems.
Extended defects-enhanced oxygen diffusion in ThO2
Miaomiao Jin, Jilang Miao, Beihan Chen +3
Oxygen self-diffusion is key to understanding stoichiometry and defect structures in oxide nuclear fuels. Experimentally, low activation-barrier oxygen migration was found in ThO$_…
An Accurate S Method for Solving Static Multigroup Neutron Transport Equations in Slab Geometry
Jilang Miao, Miaomiao Jin
This paper presents an accurate S solver for slab geometry. For constant cross-section regions, it gives accurate angular fluxes without need of fine meshes or approximation of…
