Ar concentration and exhaust power in the main plasma were proposed from a system code survey, and the plasma performance in a conventional divertor with a long leg length of 1.6 m has been studied. An integrated design of the water-cooling heat sink was proposed under the DEMO level neutral irradiation. An arrangement of the coolant rooting for Cu-alloy and F82H steel pipes in a divertor cassette was investigated. The heat transport analysis of the W-monoblock and Cu-alloy pipe under the heat load of 10 MWm-2 and nuclear heating was performed. These results were acceptable for the plasma facing and structural materials., Plasma Conference 2017 (PLASMA2017)}, title = {原型炉におけるパワー排出シナリオとダイバータ設計検討}, year = {2017} }
