Stand-alone type fusion reactor concept with no transport of radioactive materials due to the commissionnig scenario without the initial tritium loading

在目前核聚变能源的发展中，氚和氚是燃料。由于氚是一种放射性核素，所以氚不作为自然资源存在。这就是为什么确保最初的氚是关键问题之一。在这里，我们提出了一种在聚变反应堆中不需要初始氚负荷的调试方法，在该方法中，利用氚-氚聚变反应来逐步产生氚。详细研究了初始氚负荷调试方法的操作方法，并对其优化进行了讨论，以缩短调试周期，为解决确保初始氚安全的关键问题做出贡献。

In the present development of fusion energy, deuterium and tritium are the fuel. Since the tritium is a radionuclide, tritium doesn't exist as the natural resources. That is why securing the initial tritium is one of the critical issues. Here, we proposed a commissioning method without the initial tritium load in a fusion reactor, in which deuterium-deuterium fusion reaction is utilized to breed the tritium, step by step. The operation method for that commissioning method with the initial tritium load is investigated in detail, and its optimization is discussed to shorten the commissioning period and to contribute the solution of the critical issue of securing the initial tritium.
