FIRST WALL THERMONUCLEAR REACTOR Russian patent published in 1994 - IPC

FIELD: thermonuclear technology. SUBSTANCE: first wall of plasma unit is composed of two layers: outer layer is built from material impenetrable to working mixture or tritium, inner layer is manufactured from high-temperature material with low conductivity, for instance, graphite. Cylindrical spaces similar in shape and dimensions are uniformly made in inner layer over circumference. Each of them houses tritium generator. Cylindrical spaces communicate by means of ducts with inner space of plasma unit. Electrodes of generators are insulated from graphite with the aid of ceramics, for instance electric-grade porcelain, and are brought out through tight insulators installed in holes of wall of plasma unit. EFFECT: prolonged service life, increased stability of reproduction of tritium. 3 cl, 2 dwg
