This paper describes the design and experimental results regarding a solid breeder blanket for a tokamak-based fusion power plant, which is cooled with supercritical pressure water. The analysis of the system shows that a thermal efficiency of 41% can be achievable with cooling conditions of 25 MPa, 510°C. Thermo mechanical analysis of the first wall shows that the present design can withstand supercritical pressure and a high heat load from plasma. The 3D neutronics analyses show that a local TBR of more than 1.4 can be obtained. Elementary R&D concerning manufacturing techniques for the blanket structure and breeder/neutron multiplier pebbles have also been developed in parallel with the blanket design.
