最近讨论了托卡马克反应堆分三个阶段(即实验堆、示范堆和商用堆)的发展设想。为了制定可行的发展战略，有必要对反应堆技术的哪些组成部分以及发展到什么程度进行评估。从未来电力供应商的角度，我们提出了一个商业发电厂的概念设计，紧凑型反向剪切托卡马克(CREST)和一个示范发电厂，Demo-CREST。另一方面，实验堆ITER项目正在进行中，其实验计划和研发活动已基本完成。因此，研究热核实验堆轨道上的示范电厂，以展示托卡马克反应堆的具体发展情景，是最重要和最合理的。在这份报告中，我们讨论了Demo-CREST设计中的工程方面，并分析了先进托卡马克CREST的关键开发问题。为了提高单个装置的热效率，对Demo-CREST的潮流和电厂系统进行了研究，并对每个反应堆部件和每个发展阶段的发展目标进行了定量分析。
A development scenario of the tokamak reactor in three stages (i.e. the experimental reactor ITER, a demonstration reactor and a commercial reactor) has been recently discussed. In order to construct a feasible development strategy, it is necessary to evaluate which component of reactor technologies and to what extent should be developed. From the viewpoint of the future electric supplier, we have proposed the conceptual design of a commercial power plant, compact reversed shear tokamak (CREST), and a demonstration power plant, Demo-CREST. On the other hand, the project of the experimental reactor ITER is underway, and its experimental plan and R&D activities are almost completed. Hence, it is most important and reasonable to investigate the demonstration power plant on the track of ITER in order to show a specific development scenario of the tokamak reactor. In this report, we discuss the engineering aspect in the Demo-CREST design and analyse the critical development issues towards an advanced tokamak CREST. The power flow and power plant system for Demo-CREST are investigated for improvement in the thermal efficiency of a single device, and the development goals for each reactor component and for each development step are quantitatively analysed.
