TThe going global of nuclear power industry is one of China’s national strategies. This paper analyses the current situation of technology and market for nuclear power industry around the world，and predicts the potential market and technology trend in the coming decades. The research points out that the impact of Fukushima accident on the global nuclear power industry is mitigated，while the moderate recovery of the world nuclear power market is still continuingsince the beginning of the new century. However，given the fact that the global energy consumption slows down and the renewable energy gets cheaper，we conclude that the volume of short-term global market（before 2030）is quite limited. In a long-term perspective，along with the rising consumption of the developing countries and renew demands of nuclear facilities in developed countries，the nuclear power industry around the world will boom after 2030. Finally，this paper gives some policy suggestions for the going global of China’s nuclear power industry.
