磁约束聚变的进展与球形环

自１９９１年１１月以来，从ＪＥＴ、ＴＦＴＲ和ＪＴ－６０Ｕ装置的氘－氚聚变系统运行中所获得的有价值的成果表明，现已有能力研究和设计ＩＴＥＲ和先进的托卡马克型聚变堆．ＩＴＥＲ分两个阶段的设计活动（ＣＤＡ、ＥＤＡ）可于１９９８年７月完成，其中包括安全分析及实验评估在内的聚变动力堆的设计全过程．但昂贵的建造费用已成为ＩＴＥＲ进一步开发的主要矛盾，一种改进型托卡马克——球形环有可能会解决这个问题，主要借助于最小尺寸和简化结构来降低费用．文中描述了动力、实验球形环和混合堆的特征与初步参数． Since Nov. 1991 JET, TFTR, JT 60U have contributed to valuable operating experience with D T reaction systems, and have validated abilities to design ITER.
