ITER中国液态锂铅实验包层模块设计研究与实验策略

The dual functional lithium lead test blanket module and the testing strategy for ITER

在广泛调研和深入分析国际聚变堆包层发展状况的基础上,根据液态锂铅包层一般特点和中国发展的系列液态锂铅包层概念设计,提出了一个具有演示氦气单冷却剂和氦气/锂铅双冷却剂包层技术的双功能包层模块实验系统方案,对其性能进行了分析研究,作为中国向ITER实验包层工作组(TBWG)提交的液态包层实验模块最终设计描述文件的内容框架。总结了该工作主要内容,包括基本设计思想和方案描述、性能分析概况、对辅助系统的要求和实验策略与关键技术等。

Based on wide survey and analysis of development of the international fusion reactor blankets and the general characteristics of the liquid lithium-lead blankets, the Dual-Functional Lithium Lead-Test Blanket Module （DFLL-TBM） system, which is designed to demonstrate and validate the technologies of both the helium-cooled blanket and the helium/lithium lead dual-cooled blanket, is proposed for testing in ITER referring to the relevant several conceptual designs in China. The paper summarizes the con tents of the DFLL-TBM design for the Chinese Design Description Document submitted to ITER Test Blanket Working Group, including design philosophy, system description, performance analyses, requirements for ancillary systems, and testing strategy and key R＆D issues etc.
