Aqueous Salt Blanket Tritium Systems for The Titan-II Reversed-Field Pinch Fusion Reactor Design

TITAN is a high-power-density reversed-field pinch reactor design. The TITAN-II concept is based on an aqueous lithium salt blanket immersed in a loop-in-pool design to provide a high level of passive safety. The blanket uses 50 Ci/kg water in the primary heat transport circuit, and 0.4 Ci/kg in the cold water pool. The main coolant stream is treated by a 5-stage Vapor Phase Catalytic Exchange process, followed by Cryogenic Distillation. Water Distillation is used to process the cold pool. The design uses proven technologies (although on a ten times larger scale), and takes advantage of features of light water tritium recovery. Tritium losses are controlled to 50 Ci/d by leak-tight design, tritium release trapping by the cold pool, lower pressure in the primary system relative to the steam system, and air driers.
