Rattlesnake: A MOOSE-Based Multiphysics Multischeme Radiation Transport Application
Yaqi Wang,Sebastian Schunert,Javier Ortensi,Vincent Laboure,Mark DeHart,Zachary M. Prince,Fande Kong,Jackson R. Harter,Paolo Balestra,Frederick N. Gleicher +9 more
TL;DR: The spectrum from heat pipe-cooled microreactors, through thermal and fast molten-salt reactors, to gas-and salt-cooling pebble bed reactors, can be found in this paper.
Journal ArticleDOI
Hybrid PN-SN with Lagrange multiplier and upwinding for the multiscale transport capability in Rattlesnake
TL;DR: In this paper, two interface conditions, the Lagrange multiplier method and the upwinding method, for hybrid P N - S N calculations are proposed for the self-adjoint angular flux (SAAF) formulation of the transport equation using the continuous finite element method (FEM) for spatial discretization.
Journal ArticleDOI
A Newton solution for the Superhomogenization method: The PJFNK-SPH
TL;DR: In this article, the authors present two novel topics regarding the superhomogenization method: (1) the formalism for the implementation of the method with the linear Boltzmann Transport Equation, and (2) a Newton algorithm for the solution of the nonlinear problem that arises from the method.
Journal ArticleDOI
Coupled Multiphysics Simulations of Heat Pipe Microreactors Using DireWolf
Christopher Matthews,Vincent Laboure,Mark DeHart,Joshua Hansel,David Andrs,Yaqi Wang,Javier Ortensi,Richard C. Martineau +7 more
TL;DR: DireWolf as mentioned in this paper is a multiphysics software driver application designed to simulate heat pipe-cooled nuclear microreactors, which can be used to simulate nuclear power plants.
Journal ArticleDOI
Hybrid super homogenization and discontinuity factor method for continuous finite element diffusion
Vincent Laboure,Yaqi Wang,Javier Ortensi,Sebastian Schunert,Frederick N. Gleicher,Mark DeHart,Richard C. Martineau +6 more
TL;DR: A novel homogenization equivalence technique aiming to simultaneously leverage the simplicity of the Super Homogenization (SPH) method to reproduce reference reaction rates and the ability to preserve reference leakage rates at desired surfaces through Discontinuity Factors (DF).
