WebApr 12, 2024 · The passive residual heat removal (PRHR) systems are key part of the safety features of the reactor. A series of passive residual heat removal experiments have been conducted in a scaled integrated test facility for NHR-200-II by INET [8, 9]. To explain the flow phenomenon in the experiments, it was necessary to establish a detailed … WebPassive skimming techniques are designed to remove LNAPL as it flows naturally (without pumping) into a recovery well or trench. Similar to hand bailing, passive skimmers generally are used to recover LNAPL when little LNAPL remains at a site.
