聚变能源中的氚化学与氚工艺研究进展及展望

Progress of Tritium Chemistry and Technology in Fusion Energy

核聚变被认为是人类社会未来的理想能源,对社会、经济的可持续发展具有重要的战略意义。氘氚聚变反应具有反应截面大、反应速率高、点火温度低及释放能量大等优点,是目前聚变研究的主要目标,而高效的氘氚燃料循环工艺与技术是实现聚变能源商业应用的基础。本文主要介绍氘氚燃料循环所涉及的等离子体排灰气中氚的快速回收、氚的增殖与提取、大规模氢同位素分离、氚测量等相关氚化学与氚工艺的研究进展及展望,以期对未来聚变能源氚工厂相关技术的研究提供借鉴和参考。

To realize controlled fusion on the earth has been a dream of human being. Owing to extensive research and development, the fusion reaction of D and T seems to be realized. However, to realize a D-T fusion reactor as an energy source, lots of engineering issues still remain to be solved. Among all, T-relating issues are quite important, because T is radioactive and its resources are quite limited. In this paper, tritium chemistry and technology to establish the D-T reactor as an energy source are summarized.
