Verification of Neutronics and Thermal-hydraulics Coupled Simulationn Program NTC by the PDS-XADS transient simulation

摘要

In this paper, the steady state and three typical transient accidents of LBE-cooled sub-critical experimental accelerator driven system reactor were simulated by the Neutronics and Thermal-hydraulics Coupled Simulation Program (NTC) developed by FDS team. The three transient accidents were beam trip (BT), unprotected beam overpower (UBOP) and unprotected transient overpower (UTOP). The NTC-based simulation results of PDS-XADS were compared with those based on SIMMER-III, and the simulation and c
