Abstract

This study was performed within the framework of the EURISOL for facilities SPIRAL-II (GANIL, France) and SPES (LNL, Italy), and aims to investigate the anticipated strength properties of fine-grained graphite at elevated temperatures. It appears that the major parameters that affect to the lifetime of a graphite target of this IP are the temperature and heating time. High temperature tests were conducted to simulate the heating under the influence of a beam of heavy particles by passing through the sample pulse or AC to study the laws of the destruction of a graphite target. Tests carried out in this work have shown the ability to forecast the stability and durability of graphite materials that traditionally used in nuclear engineering at high temperature conditions.
