Abstract
This work is dedicated to experimental studies of the applicability of a prototype reflex radar level gauge in a heavy liquid metal coolant environment Pb-Bi, taking into account the influence of oxide coatings. Experimental studies to justify the performance were conducted in two stages: in a static tank and in the conditions of a circulation stand. In the first stage of the research, experiments were conducted on water and lead-bismuth coolants to justify the performance of the level gauge in the conditions of a heavy liquid metal coolant. In the second stage of the research, durability tests were conducted for 120 hours with constant monitoring of the coolant level, as well as stepwise draining of the coolant from the experimental tank. It has been noted that the level of error in the measurements obtained is within acceptable limits. It was experimentally proved that minor changes in geometry due to temperature gradients, formation of oxide coatings on critical parts of the level gauge, and slight adherence of the heat carrier to the surface do not affect the performance of the level gauge. The results obtained confidently demonstrate the applicability of the studied model of the level gauge in conditions of heavy liquid metal heat carriers, both for research stands and reactor installations.
