BALL THERMAL CHEMICAL ELEMENT AND ITS MANUFACTURE FOR APPLICATION IN GAS-COOLED HIGH-TEMPERATURE NUCLEAR REACTORS WITH BALL VOLUME

摘要

The proposed invention relates to a spherical fuel element and to a method of manufacturing a spherical fuel element that meets the requirements of high-temperature nuclear reactors with ball filling. According to the invention, a fuel-free shell of a spherical fuel element consists of silicon carbide (SiC) and / or zirconium carbide, as well as natural graphite and graphiteized petroleum coke, and its average nominal thickness is ≥ 1 mm.
