As part of the nuclear safety program it is desirable to fully characterize the dynamics of a vapor bubble formed in liquid sodium. The bubble would be formed during the hypothetical case of partial core vaporization in a liquid-metal reactor. A real-time ultrasonic imaging system was developed which provides simultaneous measurement of the rise velocity and radius of large spherical bubbles. The range of applicability of the UDI system has been determined in model experiments.
