Nuclear power technology industry is an important component of the new energy industry, which is one of the China's strategic emerging industries, and the development of nuclear power meets with our strategy of green low-carbon energy. According to the route that the scientific and technological breakthroughs leading to product upgrades, increasing the production capacity and industrial development, the article systematically analysis the nuclear technology foster and development outcomes during the "12th Five-Year", focusing on the development trend of China's nuclear power industry after the Fukushima accident, and the significant feature of HPR1000, the advanced nuclear power technology; put forward the development trends during "13th Five-Year" and even longer term, including the development of fuel closed-cycle system based on the fast reactor, the development of fusion technology to achieve "three-step" strategy, to explore the multipurpose utilization of nuclear energy through small module reactor technology, to achieve the goal of large-scale, sustainable nuclear power industry development, and play a greater role in promoting China's economic stability, sustainable growth, energy & industrial structure optimization and upgrading.
