Development of Terrenus: A Multiphysics Code for Spent Nuclear Fuel Canister Criticality Analysis

摘要

An initial multiphysics framework-Terrenus-has been developed to couple Monte Carlo radiation transport code Shift and thermal hydraulics code COBRA-SFS. Currently, the Terrenus code is capable of coupling Shift and COBRA-SFS for a simplified cask model containing a single PWR assembly. The Terrenus framework has been tested using a simplified 3×3 fuel pin geometry.
