Abstract :
This paper describes a conceptual design of an advanced blanket using liquid lithium lead (Li17Pb83) metal and high temperature material. Liquid lithium lead metal is expected as a material to solve some problems of solid blankets and expected to be operated at high temperature above900 degree C. We examined a feasible structure using advanced materials (the SiC/SiC compostite, reduced activation ferritic steel(RAFS)) tritium permeability, tritium breeding ratio and heat transfer behavior at high temperature above 600 C. We have obtained a TBR 1.25 with a limited thickness, and investigated the effect of neutron multiplier Be. The TBR greater than 1.4 was obtained with reasonable neutron flux and heat distribution.
