[2E02] Development of a passive safety shutdown device to prevent core damage accidents in fast reactors
(4)Selection and material property evaluation for simulated fuel and fusible plug materials
Keywords:alloy fuel, salt fuel, melting, fusible plug, material properties
In this study, the physical phenomenon of fuel melting or fusible plug melting accompanying an increase in power and temperature is used as a passive furnace shutdown device mechanism. As for the fuel form, these simulated materials were selected as alloy fuels and salt-based fuels, and various physical properties were evaluated. In the case of salt-based fuel, a fusible plug is also used, but the physical characteristics of the candidate material for this material were evaluated and a suitable material was selected.
