A conceptual design of RFP fusion power core — REPUTER-I

Abstract

REPUTER-I is a conceptual design study on a compact reversed field pinch fusion reactor with a solid breeder blanket. The first wall is structurally independent from the blanket. The blanket is composed of SiC reinforced blocks which form a stable arch, and the stresses in SiC are basically compressive. Pressurized water is chosen for the first wall and as a limiter coolant in order to remove a high heat flux, while helium gas is used for the blanket coolant. A pile of thin Li 2 O tiles and thick beryllium tile provides a satisfactory tritium breeding ratio. A pumped limiter is shown to meet the demand for heat and particle exhaust removal in a compact RFP core. Magnet system design and plasma performance analysis are made as well on the first wall, blanket and limiter design.
