In the presentation some aspects of nuclear reactor thermal hydraulics are discussed. It focusses on accident analyses for loss of coolant accidents (LOCA) and demonstrates the capabilities of system codes. In a second part recent research on the qualification of CFD codes for nuclear reactor safety issues is presented. Special attention is paid to experimental work done at HZDR to obtain CFD-grade experimental data. The TOPFLOW facility is combined with innovative measuring techniques to obtain such data.
