Accuracy of various alternate methods of calculating total mass flow rate for PKL instrumented pipe spool prototype tests in single- and two-phase steam-water flows
Instrumented spool pieces for installation in the piping of the German Primarkreislauf (PKL) test reactor have been designed and tested. The primary objective of the spools is to provide measurements of two-phase steam-water flow parameters (pressure, temperature, velocity) from which mass flow rates can be calculated. Each spool contains a three-beam densitometer, flow turbine, drag screen, and pressure and temperature sensors. The spools were prototype tested in single- and two-phase steam-water flows and the results of the mass flow calculations were compared to known values. The present software calculations of total mass flow in two-phase flows requires data from two instruments only: the flow turbine and drag screen. In this report, mass flow calculations based on other instrument combinations are investigated and compared to the programmed calculations.
