This paper describes a maintenance scheme considered for a conceptual DEMO design of JAEA (SlimCS). For horizontal removal and installation of sectors, key issues such as the functions of sector transport mechanism, cask and hot cell were outlined and their possible concepts were proposed. A new concept of supporting the turnover force of toroidal field coils were also proposed. Based on work breakdown of the maintenance scheme, the maintenance time was estimated to be 67.5 days for all the sectors, being favorable for high plant availability.
