Torus configuration and materials selection on a fusion DEMO reactor, SlimCS

Nuclear analysis of DEMO water-cooled blanket based on sub-critical water condition

“…SlimCS (central solenoid) was the conceptual design of a compact fusion DEMO plant assuming technologies foreseeable in 2020-2030 [1]. In line with the reactor design, the DEMO blanket design was conducted [2].…”

Technical issues related to the development of reduced-activation ferritic/martensitic steels as structural materials for a fusion blanket system

“…Ta-added in place of Nb to achieve the desired toughness and creep strength-is the key element for the optimization of RAFM steel fabrication technologies, as Ta is not commonly used in conventional steels. Furthermore, the fabrication technologies will require optimization, considering the mass production process necessary for DEMO construction, which requires about 3500 t of RAFM steel in various forms such as plates and tubes [3]. Joining and inspection technologies are also important for the fabrication of the DEMO blanket, because the blanket design is a complex box structure with numerous joints.…”

Deuterium retention in tungsten coating layers irradiated with deuterium and carbon ions

“…Because tungsten offers advantages such as low hydrogen solubility, low sputtering yield, and high melting point as a plasma facing material (PFM), it is one of the candidates for use in ITER and DEMO reactors [1,2]. For these devices, tungsten coating is considered to be applicable to armor tiles in low-heat-flux regions, such as blanket first walls, and solid tungsten could be used in high-heat-flux regions, such as divertor targets.…”
