Real-Time Particle Transport Simulations - MRT Methodology & RAPID code system Workshop


The goal of this workshop is to introduce the audience to the novel Multi-stage, Response-function Transport (MRT) methodology1, a Physics-based computational technique, for real-time simulation of nuclear systems. Further, it elaborates on a number of MRT-based computational tools developed for solving real-world problems in real time. Particularly, the workshop will emphasize on the recently developed RAPID code system2, 3 by giving real-time demonstration of the use of the code for solving real-world problems, e.g., a cask containing 32 spent fuel assemblies, on a laptop in real time!

The workshop will include two parts:

Part I: Discussion of the MRT methodology and its application for a few real-world problems:

  • AIMS (Active Interrogation for Monitoring of SNM).
  • INSPCT-S tool (INSPCT-S, Inspection of Nuclear Spent fuel-Pool Calculation Tool ver. Spreadsheet).
  • TITAN-IR (TITAN code system for Image Reconstruction).
  • RAPID (Real-time Analysis Particle-transport In-situ Detection).

Part II: Demonstration of the RAPID code system for simulation of spent fuel casks and pools

In a MRT methodology, the problem of interest is partitioned into stages based on its physics, and each stage is represented by a response function or set of coefficients. These stages are combined into a linear system of equations which are solved iteratively using the pre-calculated functions and/or coefficients.
