This paper reviews the recent scientific researches and the important engineering milestones in the key fields of the frontier nuclear energy science and technology, focusing on the research and project progresses in the nuclear energy engineering, the small module reactor, the fusion technology, the space reactor, and the digital reactor. The research and development of the frontier nuclear energy technology is shown to be progressing steadily in general. Small reactors have good application prospects in sea, land and air and will open up a new world of the nuclear energy utilization beyond the traditional commercial nuclear power. The advanced nuclear fuel design, the high-precision numerical simulation and other technologies are important development directions for the nuclear energy safety in the future. With the further innovation and diversity of the technology, the diversified development trend of the nuclear energy is expected to occupy an important position in the global energy structure.
