A solid moderator is designed for a high-temperature, high-pressure gas- cooled reactor which is subjected to sudden movements, e.g., in movable vehicles. The moderator comprises an assembly of parallel moderator columns in stack form, each having an axial channel for receiving fuel elements and for circulating the coolant. The columns are mutually independent and can expand laterally by reason of clearances between adjacent columns and axially by reason of resilient guide (spring) means. The supports at each end of the columns are riaintained at a low temperature so that only the columns themselves are subjected to high temperatures. (D.L.C.)
