Based on the success of the OECD/NRC BFBT Benchmark, Japan released data based on the NUPEC PWR Sub-channel and Bundle Tests (PSBT) Benchmark and asked Pennsylvania State University (PSU) in the United States to organise and conduct the benchmark activity. Void fraction measurements and departure from nucleate boiling (DNB) tests were performed at NUPEC under the conditions simulating PWR thermal-hydraulic conditions, including the steady-states and the transients such as the power increase, the flow reduction, the depressurisation and the temperature increase.
