中国国际热核聚变实验堆(ITER)氦冷固态氚增殖剂实验包层模块(CH ITER HC-SB TBM)设计已经完成.给出了HC-SB TBM的总体设计、性能分析和相关辅助系统的设计.HC-SB TBM氚增殖区的设计采用BOT概念, 锂陶瓷做氚增殖剂, 氦气做冷却剂和载氚介质, 铁素体马氏体钢做结构材料, 铍做中子倍增材料.设计和分析结果表明, 所提出的设计具有高氚增殖率、结构简单和工程上可行的特点.
Preliminary design and analysis for China helium-cooled solid breeder (CH HC-SB) test blanket module (TBM) for testing in ITER(International Thermonuclear Experimental Reactor) device have been carried out recently. In this paper, the design description, the performance analysis and the related ancillary systems for CH TBM are introduced. The key features of the design are based upon the breeder-outside-tube (BOT) concept, on the use of solid breeder ceramic material, of helium as coolant and tritium purge gas, of ferrite-martensite steel as structural material, and of beryllium as neutron multiplier. Results show that the proposed TBM concept has the advantages of higher tritium breeding ratio (TBR), simple structure design and engineering feasibility.
