Abstract

This study of a fusion reactor power blanket and its associated equipment had the objective of producing a conceptual design for a blanket sector of INTOR, or one of its national variants (e.g. NET), from which electricity could be generated simultaneously with the breeding of tritium. A honeycomb blanket structure of stainless steel supports solid breeder elements of lithium metasilicate and beryllium neutron multiplier. These are cooled by helium at a pressure of 50 bar. The helium at an outlet temperature of 580 degrees C, raises steam at 500 degrees C and at a pressure of 170 bar, which is delivered to a 7 MW(e) turbogenerator. Tritium diffuses continuously from the breeder material into the main helium coolant stream and is extracted from a circuit which samples a small fraction of the flow. A local tritium breeding ratio of about 1.26 is achieved, together with a blanket coverage of the plasma of about 60 %. It is concluded that such a blanket design would be feasible after some reasonable developments in current technology.
