An Interactive Visualization Platform for Reactor-core Modeling and Neutronics Analysis

Abstract

We developed an interactive visualization tool (GRIND-P) to support nuclear reactor core modeling and neutronic analysis. It is an integrated platform that envelops an end-to-end graphical interface for unit-cell and full-core modeling, respectively. It provides a user-friendly visual interface for input preparation, problem parameter setting and both qualitative and quantitative interpretation of the results. 3D visual interface for GRIND-P not only allows quick editing and alteration of geometrical and material properties of a core-model but also helps in identifying logical errors through visual verification. Similarly, modeling abnormalities can easily be identified through better visualization of the results. It provides easy navigation across unit-cell and full-core models that simplify the execution of production work requiring many repetitive-type calculations. Moreover, the integrated platform enforces source control mechanism to backup and keep track of project-related files and their alteration history to avoid inadvertent changes.
