Multi-physics coupling simulation in virtual reactors:

TL;DR: In this paper, the three dimension multi-group neutron transport Monte-Carlo program MCMG-II and the multi group point burnup program STEP1.0 based on linear chain method are adopted in the transport-burnup coupling system.

TL;DR: An initial data interface between the structural mechanics code Diablo and the SHARP reactor simulation system data hub MOAB has been exercised both to write MOAB databases from Diablo, and then to use such a database to read in part of a simulation definition for a subsequent Diablo execution.

TL;DR: In this article, an overview of work performed under the work package entitled “FY2014 NEAMS INL-Engineering Scale Fuel Performance & Interface with RPL Tools.”

TL;DR: MOOSE as mentioned in this paper is a parallel computational framework targeted at solving coupled, nonlinear partial di?erential equations often arise in sim- ulation of nuclear processes, which is based on mathematics based on Jacobian-free Newton Krylov (JFNK).

TL;DR: An overview of the HDF5 technology suite and some of its applications is given and the data model, the software architecture and its performance enhancing capabilities are discussed.

TL;DR: This study considers multiphysics applications from algorithmic and architectural perspectives, where “algorithmic” includes both mathematical analysis and computational complexity, and “architectural’ includes both software and hardware environments.

TL;DR: Examples based on the KAIST-3A benchmark core, as well as a simplified Westinghouse AP-1000 configuration, demonstrate the power of this new framework for tackling—in a coupled, multiscale manner—crucial reactor phenomena such as CRUD-induced power shift and fuel shuffle.
