[1H01] Advanced Multi-Scale Modeling and Experimental Tests on Fuel Degradation in Severe Accident Conditions (1)


*Yuji Nagae1, Masaki Kurata1 (1. JAEA)

Keywords:Degradation, Solidification, Sever accident, Modeling

We provide informative models for fundamental process, thermodynamic data and experimental knowledge to understand phenomenon in sever accident under steam starved conditions specially. The developed models, for example oxidation/hydrogen absorption model, are being incorporated in the JUPITER code developed by JAEA. Solidification model is being developed based on thermodynamic data and experimental tests.
