Computer Codes Developed by the Lab
HADES-SNU (High-level rAdiowaste Disposal Evaluation Simulator by SNU):
Multiphysics Modeling for Geological Repository
HADES, built in the MOOSE Framework, can simulate multiphysics behaviors of chemical processes and material performance in engineered barrier systems at a geological repository. It covers thermal, fluid, mass transport, chemical, electrochemical, and radiolytic phenomena.

BOTANI:
Multiphysics Modeling of CRUD Growth and Chemistry
A high-fidelity multi-physics FEM code to simulate the growth of porous CRUD (Chalk River Unidentified Deposits) and the boron chemistry and hideout within the deposits by coupling thermal, fluid, transport, chemical, and radiolysis phenomena with MPI parallel computing.
​
Developed and then delivered to KHNP.

SNUBIC (SNU Boron Investigator with CRUD growth):
1D Fast Scalable Simulator for CRUD Growth and Chemistry
A radial 1D multi-physics modeling can be applied for each section of nuclear fuel rods to simulate the growth of porous CRUD (Chalk River Unidentified Deposits) and the boron chemistry and hideout within the deposits by coupling thermal, fluid, transport, chemical, precipitation, microstructure changes, and radiolysis phenomena with MPI parallel computing. It can be used for calculating CRUD composition and thermal properties.
