摘要：The results of an experimental study of the hydrodynamics and heat transfer of a pebble bed in a cylindrical channel and in a model of a fuel assembly with microfuels (FA MT) with a cross flow of a coolant are presented. Data on the temperature distribution along the height and the pebble radius for volumetric heat release, as well as data on pressure losses over a wide range of mass flow rates of the coolant from 0.05 to 1.75 kg/s are obtained.
