Abstract

Abstract

The paper presents a design of passive heat-switch between pressure tube and calandria tube of Thorium-based Advanced Nuclear Energy System. The heat-switch is based on shape memory alloys （SMA）. When the temperature of the pressure tube reaches 340℃, the SMA in the heat-switch will change its shape to drive heat conductors to connect the pressure tube, and calandria tube results in heat transferred from pressure tube to the calandria tube and the moderator. The passive moderator cooling system will bring the heat to the environment finally. A heat-switch with 24 slices can satisfy the requirement by theory calculation.
