•Experiments dropping uranium into sodium filled pin bundle geometry were conducted.•Post-test radiographic images were used to confirm how the uranium was relocated.•Pressure drop was measured to evaluate the blockage of the sodium coolant channel.•The more formation of the eutectics could lead to...
