Ultrasonic density detector for vessel and reactor core two-phase measurements
Abstract
A local ultrasonic density detector was developed for the Loss-of-Fluid Test reactor vessel and core two-phase flow density measurements. The principle of operating the sensor is the change in propagation time of a torsional ultrasonic wave in a metal transmission line as a function of the density of the surrounding media. A theoretical physics model is presented which represents the total propagation time as a function of the sensor modulus of elasticity and polar moment of inertia.
