Keywords:Tungsten, Neutron irradiation, Irradiation effects, Microstructural development

The results of electrical resistivity, hardness measurements and microstrucrural development of tungsten material after neutrotron irradiation in HFIR of the US ORNL with thermal neutron shield under the Japan-US collaboration project PHENIX will be presented. The irradiation conditions were 0.4 to 0.7 dpa at 600, 800, and 1100 ° C. Corelation between the microstructure and material property changes will be discussed.
