.: *.: 6 The thermal model for the TMI Heated Vacuum Drying system as reported in Reference 1 was used to calculate the predicted temperature response in the system with conditions representative of those for drying runs TMl-005 and TMl-009. The ABAQUS model is a two-dimensional representation and thus some assumptions were required to provide a reasonable approximation.
The dryer has several plates distributed along the vertical height. The calculated weight for these plates was 1281 pounds. This mass was distributed uniformly in the air zone. Information from A.
Christensen was that a heater power of 50 kW was to be used since a calculation with radiation only indicated that - 4 kW would be lost to the cooled upper head. The mass of water for the two runs-600 pounds and 765 pounds for 005 and 009, respectively was distributed with 39.23 pounds in the Licon and 120. 77 pounds in the debri for each canister for 005 and 167 pounds in the debri for 009 while the Licon was assumed the same as for 005.. It was assumed that 12 pounds was not vaporized from the Licon.
The specific heat for the Licon and debri zones was modified by adding the energy required to vaporize the water at time zero, and then modifying the specific heat with time to reflect the remaining water, using the field variable and dependency capabilities of ABAQUS. Late information indicated that the density assumed for the debri zone was high, however the primary influence is the energy required to vaporize the water and the value is coupled to the density. So a lower density would result in a higher specific heat and the results would be the same until late in the transient. The model tended to over predict the temperature for TIT-4 late and a lower density would increase the overprediction.
The top head is water cooled and this could not be modeled with the two-dimensional model. Runs with a full heater output of 50 kW resulted in over prediction of the heater temperatures. A reasonable match was obtained by assuming a heater power of 35 kW for a power factor of 100 percent for TMl-005 and a heater power of 25 kW for a power factor of 100 percent for TMl-009. This tends to indicate that a significant portion of the heater output may be utilized in re-vaporizing steam condensed on the cooled top head.
Two cases were evaluated. One assumed that the gas/vapor zone was represented by air with an enhanced thermal conductivity during the time the evaporation rate was higher, and was represented by air during the latter drying stage. The second case assumed the thermal conductivity in this zone was represented by steel since the thermocouple, TIT-4 was located near a steel spacer. The measured and calculated temperatures during the drying runs are attached.
