Advanced Two-Phase Flow Instrumentation Program. Quarterly progress report, April-June 1980
Work performed to develop and evaluate liquid level sensors for in-vessel use in pressurized water reactors is described. Experiments were performed with three thermal-type level sensors in natural convection to saturated water and steam. Pressures in those tests ranged from 0.1 to 8.6 MPa (15 to 1250 psia). Thermal-type sensors were also tested in steam-water forced convection at low and moderate pressures. Sensor response was found to be insensitive to flow velocity and void fraction but sensitive to the presence or absence of a liquid phase. A series of meetings was held with representatives of three pressurized water reactor vendors regarding research goals and implementation of reactor-vessel monitoring instrumentation.
