磁约束聚变能源具有安全、经济和环境友好的优点，是未来理想的战略能源，可为“双碳”目标的实现做出重大贡献。磁约束聚变是利用磁场将氘和氚燃料以等离子体的形式约束并发生聚变反应，被认为有希望彻底解决人类的能源问题，也是中国核能发展的长远目标。当前中国正在积极参加国际热核聚变实验堆（ITER）的建设，支持国内ITER专项的物理和工程技术研究，在吸收和消化ITER经验的基础上，自主设计以获取聚变能源为目标的中国聚变工程试验堆（CFETR）。聚变能源开发难度很大，机遇和挑战并存，需要长期持续攻关。
With the advantages of safety, economy and environmental friendliness, magnetic confinement fusion energy is an ideal strategic energy for the future and can make a significant contribution to the realization of the "double carbon" goal. Magnetic confinement fusion uses magnetic field to confine and fuse deuterium and tritium fuels in the form of plasma, which is considered to be a promising solution to the energy problem of mankind and a long-term goal for the development of nuclear energy in China. At present, China is actively participating in the construction of the International Thermonuclear Experimental Reactor (ITER), supporting domestic physics and engineering research, and designing the Chinese Fusion Engineering Testing Reactor (CFETR), with the goal of obtaining fusion energy on the basis of absorbing and digesting ITER experience. This article addresses both opportunities and challenges for fusion energy development which is very difficult and requires long-term sustained research.
