E-mail address: kovalentek.ru Abstract RF DEMO-S reactor is a prototype of commercial fusion reactors for further generation. A blanket is the main element uit of the reactor design. The segment structure is the basis of the ceramic blanket. The segments mounting/dismounting operations are carried out through the vacuum vessel vertical port. The inboard/outboard blanket segment is the modules welded design, which are welded by back plate. The module contains the back plate, the first wall, lateral walls and breeding zone. The 9CrMoVNb steel is used as structural material. The module internal space formed by the first wall, lateral walls and back plate is used for breeding zone arrangement. The breeding zone design based upon the poloidal BIT (Breeder Inside Tube) concept. The beryllium is used as multi lier material and the lithium orthosilicate is used as breeder material. The helium at 0. 1 MPa is used as purge gas. The cooling is provided by helium at 10 MPa.
