EFFECT OF INORGANIC MATERIALS ON THE BEHAVIOR OF SUPERCRITICAL WATER NEAR PSEUDOSPINODAL

Supercritical water is a promising working fluid in the new nuclear power plants of the 4th generation. Due to the presence of the pseudo-critical line, thermo-hydraulic as well as physical and chemical properties of supercritical water differ significantly from the pressurized hot water used in cooling loops of water reactors. The impact of small amount of inorganic substances addition to the thermal properties and hydraulics of the supercritical water utilized as working fluid for nuclear reactors cooling as well as nonnuclear supercritical water-cooling loops applications is analyzed in the paper.
