Calculation of evaporation term storage of radioactive waste

The results of theoretical calculation of the temperature of the thermal field in the standard 200 - liter barrel for three different processes: cooling water and the cement compound, heat release of radioactive decay of radionuclides in the cement - rated compounds, hardening the cement compound. With the help of the numerical model has been shown that in the hardening cement compound internal volume Boch matches heated to 90 °C or more, and with respect to the central regions of overheating the peripheral is 25 to 30 degrees. Created on installation for direct measurement of the temperature field in the barrel and on the surface of its heat exchange with the environment assessed thermophysical characteristics of the barrel and the curing process of the cement compound. Calculated the average heat transfer coefficient for the entire cooling surface was equal to 9.86 barrels vatt/m 2 ·K, which is almost two times higher than the value calculated by conventional criteria equations. The intensity of heat in the process of hardening of the cement compound significantly increases with a decrease in J/Q
