Design of Passive Heat-switch between Pressure Tube and Calandria Tube of Thorium-based Advanced Nuclear Energy System

摘要: 提出了一种用于钍基先进核能系统压力管与排管之间的非能动热开关设计方案。该热开关基于形状记忆合金原理,当压力管的温度达到340℃的时候,热开关中的形状记忆合金部分开始变形,推动导热部件移动,使得压力管和排管之间通过导热部件接触。从而将堆芯内的热量从压力管传到排管和慢化剂,再通过慢化剂冷却系统把热量带出并最终释放到周围环境之中。理论计算表明,24片的热开关组件可以满足设计要求。

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.
