2024-08-12 Pressure build-up characteristics experimental data during a water jet injection into a molten lead-bismuth eutectic pool in the PMCI facility doi:10.57760/sciencedb.j00186.00230 en To understand the pressure build-up characteristics of water jet injection into a molten Lead-Bismuth-Eutectic (LBE) pool, which is a key phenomenon during a Steam Generator Tube Rupture (SGTR) accident of lead-cooled fast reactors, a seris of experiments have been conducted by injecting water jet into a molten LBE pool at Sun Yat-sen University from 2022 to 2023. To clearify the influence of each experimental parameter on pressure build-up characteristics, a wide range of parameters was employed in the experiments, including LBE temperature, water subcooling, injection pressure, injection time, and nozzle diameter.The interaction vessel in which the LBE-water interaction occurs is a stainless steel cylindrical container with an inner diameter of 250 mm, a height of 750 mm, and a design pressure of 40 MPa. Many thermocouples and sensors are installed on the interaction vessel wall to obtain the temperature and pressure trends of the melt pool and cover gas.This data set includes the figures as well as the original data for make these figures:Fig.2: Boiling mode predicted according to above thermal criterion for each experimental case;Fig. 3, 4, 9: Temperature and pressure trends in the experimental cases;Fig. 5-8, 10, 11: Influence of each experimental paramter and interaction mode on pressure build-up characteristics;Fig. 12.
