Image Number 2 for United States Patent #5096657.
A system for detecting steam voids or bubbles within a reactor coolant system. A dynamic pressure transducer detects pressure fluctuations in the coolant system and produces signals representative of steam voids within the system. The signals produced by the transducer are conditioned and applied as an input to a microprocessor along with other inputs representative of other operating parameters for the reactor coolant system. The microprocessor adjusts the signals representative of steam voids within the system and displays same to the operator.
