The need to refine models for best-estimate calculations based on good-quality experimental data has arisen for various nuclear applications. One of the most extensive and valuable databases available was developed by the Nuclear Power Engineering Corporation (NUPEC) of Japan, consisting of both void distribution and Departure from Nucleate Boiling (DNB) data for a representative Pressurised Water Reactor (PWR) fuel assembly. A part of this database has been made available for the PWR Sub-channel and Bundle Tests (PSBT) Benchmark. This benchmark follows the highly successful BWR Full-size Fine-mesh Bundle Tests (BFBT) Benchmark.
