本文介绍了国际聚变材料辐照设施（IFMIF）液态锂（Li）靶系统的最新设计。 IFMIF 是一种加速器驱动的强中子源，用于聚变反应堆材料测试。两束总电流为 250 mA 的 40 MeV 氘核束撞击在 Li 回路中循环的液态 Li 目标。 Li的目标是以10-20 m/s的速度提供稳定的Li射流，以处理1 GW/m(2)的平均热通量，应用凹形Li流以避免Li沸腾。采用冷阱和两种热阱将杂质（T、(7)Be、C、O、N）控制在允许水平以下。由 RAFM 制成的后墙位于中子辐照最严重的区域（50 dpa/年）。在工厂生命周期内，系统可用性要求超过 95%。包括 Li Loop 在内的 EVEDA 任务现在正在更广泛的方法下执行。 (C) 2008 Elsevier B.V. 保留所有权利。
This paper describes the latest design of liquid lithium (Li) target system in International Fusion Materials Irradiation Facility (IFMIF). IFMIF is an accelerator-driven intense neutron source for fusion reactor materials testing. Two 40 MeV deuteron beams with a total current of 250 mA strikes a liquid Li target circulating in a Li loop. The Li target is to provide a stable Li jet at a speed of 10-20 m/s to handle an averaged heat flux of 1 GW/m(2), A concaved Li flow is applied to avoid Li boiling. A cold trap and two kinds of hot trap are applied to control impurities (T, (7)Be, C, O, N) below permissible levels. A back wall made of RAFM is located in the most severe region of neutron irradiation (50 dpa/year). System availability requires more than 95% during plant lifetime. EVEDA tasks including Li loop are now being performed under the Broader Approach. (C) 2008 Elsevier B.V. All rights reserved.
