A five-year research project started in FY2005 to develop a code based on the MPS (Moving Particle Semi-implicit) method for detailed analysis of core disruptive accidents (CDAs) in sodium-cooled fast reactors (SFRs). The code is named COMPASS (Computer Code with MPS for Reactor Safety Analysis) . In this project, both mixed-oxide (MOX) and metal fuels are considered as a fuel material component. One of the main features of the project is to investigate eutectic reactions between the metal fuel and the cladding/structure materials with phase diagram calculation, classical and first principle molecular dynamics (CMD and FPMD) methods. This paper presents outcomes from study with FPMD.
