Optical Flowmeter for Measuring the Coolant Flow Rate in the Primary Loop of a Nuclear Reactor

  • Published:
Atomic Energy Aims and scope

The necessity for developing new models of flowmeters and devices for measuring the flow rate of a coolant with oxygen activity in the primary circuit of NPP reactors, both in operation and in advanced development, is substantiated. A new design of an optical flowmeter with a real-time marking mode of flow measurement is presented. The procedure for measuring the coolant flow rate is considered and the operational features of the optical flowmeter are noted. The marking mode and other research-based design solutions made it possible to measure the coolant flow rate with error <1%. It was demonstrated that the developed optical flowmeter has practical utility for controlling the flow rate of a coolant with oxygen activity.
