In this article, we summarize the experimental results obtained in large-scale thermal-hydraulics PANDA facility (PSI, Switzerland) within OECD/NEA HYMERES2 project. The experiments addressing hydrogen distribution allowed characterizing flow patterns forming from jet flows impacting plates or grating platforms and following interaction with a postulated cloud containment dome. activation of sa...

Exercises 1 and 2 of the VVER-1000 Coolant Transient Benchmark Phase 2 (V1000CT-2) are investigated using coupled three-dimensional (3-D) neutron kinetics/thermal-hydraulics code TRACE/PARCS. Two coarse mesh 3-D thermal-hydraulic models (with six angular sectors and with eighteen angular sectors) were developed for the system code TRACE for Exercise 1 and their applicability is evaluated using ...
