R&Ds on divertor high heat flux components are one of the key issues to realize for fusion experimental reactors such as ITER. JAERI has been developing the divertor components to meet the ITER design. The annular tube has been developed to reduce space and costs of the divertor. To optimize the annular tube design, pressure drop was measured with different end-plug structures. As the result, the lowest pressure drop of 0.1MPa at the flow velocity of 10m/s was obtained at the 7.5mm round shape end-plug section. The W/Cu hot pressing method has been also developed to improve the reliability and to reduce the cost. Thermal cycle test was performed on the W/Cu hot pressing divertor mock-up to investigate the durability of the joining interface. As the result, the surface temperature shows almost constant throughout the experiment, and no degradation of the thermal response is found through 3000 cycles.
