Abstract
An integrated model of the TOPAZ‐II space nuclear reactor system is developed based on the Thermionic Transient Analysis Model (TITAM). The comparison of the TOPAZ‐II system model predictions with measurements from the TOPAZ‐II, V‐71 tests showed a good agreement with experimental data. The calculated coolant temperatures are within 15 K and the calculated coolant pressure is within 12% of measurements. For a given reactor thermal power, the model calculates various operation parameters of the system, namely: (a) the coolant flow rate and the temperature and pressure distributions throughout the coolant loop, (b) the electromagnetic pump current, voltage, magnetic field strength, and pressure head, (c) the load electric voltage and current, (d) the axial and radial temperature distributions in the different reactor core components, and (e) the J‐V characteristics of the thermionic fuel elements.
