In this study, the isotropic graphite IG-110 of Toyo Tanso was investigated. Shore hardness test, compressive test, bending test and fracture toughness test were conducted. Compressive test, bending test and fracture toughness test were performed by MTS- 810. Test velocity of compressive and bending test were 0.5 mm/min and fracture toughness test were 0.1 mm/min. The results were compared with manufacturer data of Toyo Tanso. Through irradiation test using HANARO research reactor, hardness and strength of nuclear graphite IG-110 was examined. Generally, strength and hardness of irradiated steel is higher than non-irradiated it. But nuclear graphite IG-110 declined unlike steel. To search for characteristic change of nuclear graphite IG-110 under the amounts of neutron, Once again the experiment changed amounts of neutron was conducted.
