In order to clarify sedimentation behavior of fuel debris during core disruptive accidents in sodium-cooled fast reactors, fundamental experiments were carried out, where solid particles simulating fuel debris were injected into a water pool. Based on the experimental results, sedimentation behavior and bed formation of different particles in properties were characterized.
