Development of commissioning method for fusion power plant without initial tritium supply

由于世界市场上的氚库存有限，如何保证初始氚库存是演示操作的关键问题之一。因此，为了保证演示实验的初始氚存量，必须采取某种对策。综合解决方案之一是没有初始氚库存的调试方案，其中由NBI束流直接反应辅助的DD聚变反应产生和增殖的氚用于聚变电站的调试。这项研究表明，有一个潜在的等离子体调试方案没有初始氚库存Demo-CREST。

One of the critical issues for DEMO is how to ensure the initial tritium inventory, because of the limited tritium stock in the world market. Hence, in order to ensure the initial tritium inventory for DEMO, some kind of countermeasures is necessary. One of the comprehensive solutions is the commissioning scenario without the initial tritium inventory, in which the tritium produced and bred by the DD fusion reaction assisted by the NBI beam direct reaction are employed for the commissioning of the fusion power plant. This study has revealed that there is a potential of the plasma commissioning scenario without the initial tritium inventory for Demo-CREST.
