Abstract

Future fusion reactors must be able to breed the tritium they will consume. Several breeding and tritium extraction technologies are under investigation internationally. PbLi is of particular interest as a breeder material. A new forced convection PbLi loop, the Tritium Extraction eXperiment (TEX), is being designed and constructed to investigate tritium extraction from PbLi. Specifically, TEX will serve to investigate the extraction efficiency of various vacuum permeator membranes and configurations. The major components of the loop include a moving magnet pump, reverse permeator, furnace test section, analysis chamber, supply tank, and plenum. As significant hazards are present in such experiments, safety is an integral focus of the experimental design.

摘要

未来的聚变反应堆必须能够培育它们将消耗的氚。国际上正在研究几种育种和氚提取技术。PbLi 作为繁殖材料特别令人感兴趣。正在设计和建造一种新的强制对流 PbLi 回路，即氚提取实验 (TEX)，以研究从 PbLi 中提取氚。具体而言，TEX 将用于研究各种真空渗透膜和配置的提取效率。回路的主要部件包括动磁泵、反向渗透器、熔炉测试部分、分析室、供应罐和增压室。由于此类实验中存在重大危险，因此安全性是实验设计的一个整体重点。
