The high-temperature engineering test teactor (HTTR) is a gas-cooled reactor being developed in JAERI. A thermal mixing test of coolant in a core bottom structure (CBS) was conducted in order to estimate the influence of the hot streak on an intermediate heat exchanger (IHX) and a pressurized-water cooler (PWC) installed at a downstream location from the HTTR. An experimental study was carried out using an in-core structure test section (a full-scale simulation model of the CBS) of the helium engineering demonstration loop (HENDEL), and a numerical study was made using a three-dimensional time-dependent flow and heat transfer code and k-ε model of turbulence. It was confirmed that coolant was mixed sufficiently in the CBS and an outlet gas duct of the HTTR and a hot streak had little effect on the IHX and the PWC.
