A common critical issue is the large power exhaust in the main plasma and divertor by the radiative cooling. (i) Different exhaust concepts in the main plasma and divertor have been developed for JA and EU DEMOs, and both divertor operations were systematically simulated and compared. (ii) Integrated designs of the heat removal components and cassette structures also have been developed. (iii) Both divertor designs are adequate to handle the peak heat loads on the target (qtarget) of 10 MW/m2 level under neutron irradiation condition., 28th IAEA Fusion Energy Conference}, title = {Plasma Exhaust and Divertor Designs in Japan and Europe Broader Approach, DEMO Design Activity}, year = {2021} }
