Components such as a blanket or divertor and instruments are exposed to a severe neutron irradiation field. As regards engineering, it is needed to grasp the characteristics of the components and instruments under neutron irradiation. Especially, a fusion blanket is the center of components, because it breeds tritium, generating heat energy and shielding neutron. Therefore, it is necessary to evaluate the in-pile functions of the blanket under neutron irradiation so as to construct ITER. JMTR of the Oarai Establishment at JAERI is conducting in-pile functional tests of a blanket mock-up, the development of blanket materials, the development of instruments, a re-weldability test for vacuum vessel materials, an electron beam irradiation test of the divertor and armor materials after neutron irradiation and so on. This report briefly describes the present status of each study.
