• Cladding failure assessment  

• Fuel assembly transportability assessment 

Spent nuclear fuel (SNF), also known as used nuclear fuel, is the fuel that has been used in nuclear reactors to generate electricity and discharged after intended period of time. Despite being less efficient for electricity generation, SNF remains highly radioactive and thermally hot. Therefore, it needs to be carefully managed and stored to prevent environmental contamination and ensure public safety. For safe and economic management, the structural integrity of SNF should be maintained under normal condition of storage and transportation. We are developing framework and criteria for SNF mechanical integrity and transportability assessment. This research necessitates intricate engineering analyses involving complex layers of engineering systems spanning from meso-scale cladding tubes to a large scale transport cask. We address these challenges utilizing model reduction techniques and state-of-the-art computational analysis methods with optimization.
