Estimation of the quantity of the suspended phase forming during the interaction of water with sodium

Calculations were performed based on the results of experiments on a model with a tube bundle to determine the amount of the suspended phase formed during the interaction of water with sodium. Due to the lack of accurate data on the dilution of the reaction products in the annular space of the tube bundle, the average dilution value equal to 88 was taken into account in the calculations. Using the measurement data from electrochemical sensors, as well as the average dilution of the solution as it moved from the reaction zone to the sensors, the actual concentration of water (equivalent) at the boundaries of the reaction zone were obtained. The concentration of the reaction product (in terms of water equivalent) not involved in dilution was determined as the difference between the initial water concentration and the concentration of water equivalent at the boundaries of the reaction zone. It is assumed that at the reaction zone, an alkali suspension is formed, which mainly does not participate in the dilution. The calculated concentration of the suspended alkali phase at the exit from the reaction zone of water with sodium when using the readings of four sensors in the assessment is from 1480 ppm to 2140 ppm, while the percentage of water used to form alkali suspension is from 81.2 % to 90.8 %.
