FEB-E(Fusion Experimental Breeder)是聚变实验增殖堆的工程概要设计。FEB的主要目标是:(1)演示混合堆工程特性和裂变燃:抖和氚的增殖性能;(2)试验混合堆关键部件和聚变结构材料。环向场线圈TFC位于真空室及屏蔽层外侧,是FEB-E关键部件之一,其造价约占整个堆的40%。TFC由超导(Nb_3Sn)、绝缘体(聚酰亚胺)、稳定剂(Cu)和结构(316SS)等材料组成。由于TFC的超导、绝热和绝缘等材料易受来自堆芯聚变中子的辐照损伤,从而会严重影响混合堆的经济、稳定及安全运行,因此需要在等离子体堆芯与TFC之间设置一个屏蔽层把TFC所受的辐照损伤和核热沉积严格要求在允许范围以内。
FEB-E (Fusion Experimental Breeder) is a schematic design of a fusion experimental reactor. The main objectives of the FEB are: (1) Demonstrate the engineering properties of hybrid reactors and fission combustion: proliferation of tritium and tritium; and (2) test of key components of hybrid reactors and fusion structural materials. The toroidal field coil TFC, located outside the vacuum chamber and shield, is one of the key FEB-E components and costs approximately 40% of the entire stack. TFC by the superconducting (Nb_3Sn), insulator (polyimide), stabilizer (Cu) and structure (316SS) and other materials. Due to the superconductivity of TFCs, materials such as insulation and insulation are susceptible to irradiation damage from core fusion neutrons, which can seriously affect the economy, stability and safe operation of the hybrid stack and therefore require the plasma reactor to be placed between the core and the TFC A shield to the TFC exposure to radiation damage and nuclear heat deposition strict requirements within the allowable range.
