Discrete element simulation of Pebble Bed Reactors on graphics processing units
Prediction of pebble positions in a Pebble Bed Reactor (PBR) is necessary for both reactor physics and thermal hydraulics simulations as the arrangement of pebbles has a significant impact on the resulting core power, coolant flow, and fuel temperature. Knowledge of pebble movement as the fuel is cycled through the core is also critical for […]
Generation of localized reactor point kinetics parameters using coupled neutronic and thermal fluid models for pebble-bed reactor transient analysis
The systems analysis of anticipated operating occurrences and design basis accidents for pebble-bed reactor systems requires knowledge of neutron point kinetic parameters. These parameters take into account various types of feedback from the pebble-bed core and are typically integrated into systems analysis tools. Typically, the generation of neutron kinetics parameters is performed in a global […]
