DOI: 10.1016/j.nucengdes.2018.04.016
Abstract: Abstract The lower plenum of a High-Temperature Gas-Cooled Reactor (HTGR) consists of numerous jets from the core mixing together across a wide range of temperatures (differences as high as 300–400 K) and velocities (50–100 m/s). The flow… read more here.
