Application of a Thermocouple-Correlation-Type Transit-Time Flowmeter in a Pressurized Water Reactor Environment

摘要

A thermocouple-correlation type of transit-time flowmeter has been developed for use in the primary coolant system of a pressurized water reactor. In this application, an assembly of sensors was used in an attempt to measure a velocity profile within the coolant piping during a simulated loss-of-coolant accident. Results indicate that the flowmeter is usable in subcooled fluid conditions but in saturated fluid conditions the output of the flowmeter cannot be related to flow. (ERA citation 09:030869)
