Abstract: Advances in complex networks of nuclear science and technology were reviewed and summarized. These complex networks include both traditional and mixing beam transport network (BTN) and control methods of halo-chaos, continuum percolation evolving network, global nuclear power station network, chemistry reaction networks, nuclear energy weapon network and network centric warfare (NWC), and radiological monitoring and anti-terror networks, integrated system network of American nuclear weapon, and so on. Some challenge issues and potential applied prospects of network science were pointed out finally.
