The temperature distribution in the coolant flow through the core of a gas-cooled pebble bed reactor was investigated. The following model was introduced for numerical solution: the core is subdivided by coaxial hollow cylinders, i.e., in coolant channels with annular cross sections. According to the nonuniform heat production within the core (according to the flux distribution) the coolant tends to expand more strongly in the inner coolant channels than in the outer ones. The walls of the assumed cylinders may be displaced in radial direction in such a way that constant pressure within any cross section perpendicular to the axis of the core is established. By this measure a picture of the coolant flow through the pebble bed core is obtained. The effective heat conductivity of the streaming coolant caused by turbulent eddies and mixing is neglected. Former publications on this subject are considered. (auth)
