Description
Possibility of measurement of oxygen concentration in sodium discussed in the papier. Usually by means of the plug indicator “plugging temperature” is measured and supposed it is equal saturation temperature of sodium with impurities. Then, concentration of oxygen is determined using equation for solubility of oxygen in sodium. As a rule, Noden´s equation is used. But solubility of oxygen in sodium depends on presence of other impurities in sodium. So, many equations for solubility of oxygen in sodium exist which are proposed by different authors at different conditions. Now 19 equations are known. Difference of these equations arise ten times and more at the plugging temperature 250-110°C. Authors of the papier have compared these equations and found out that almost all equations comes together at the temperature 558K and gives logarithm of concentration 1,957. As soon as, this point satisfies all equations it can be used for calibration plug indicator and to get equation solubility of oxygen in sodium adequate to real facility and conditions. Using the equation allows to measure oxygen concentration correct.
