abstract

The effective thermal diffusivity and conductivity of pebble bed in the High Temperature Gas-cooled Reactor (HTGR) are two vital parameters to determine the operating temperature and power in varisized reactors with the restriction of inherent safety. A high-temperature heat transfer test facility and its inverse method for processing experimental data are presented in this work. The effective thermal diffusivity of pebble bed will be measured at temperature up to 1600 °C in the under-construction facility with the full-scale in radius. The inverse method presents a global optimal relationship between thermal diffusivity and temperature through those thermocouple values in the pebble bed facility. Furthermore, the robustness and uncertainty analyses are also set forth here to illustrate the validity of the algorithm and the corresponding experiment.
