Model Description
The K-HPMR multiphysics model was previously established with thermal-only model encompassing both steady-state and transient analyses. A thermomechanical modeling capability is introduced to the K-HPMR multiphysics model to evaluate structural deformation of the reactor core, assess its feedback effects on neutronics, and provide boundary conditions for future TRISO fuel performance analyses. This thermomechanical extension supports both steady-state operation and load-following transient scenarios.
Project description
ANL team funded by NEAMS.
Impact
Example of whole core steady-state and transient multiphysics analysis with displaced mesh.
Improved K-HPMR model by calculating stress propagation.
