Abstract: Nuclear power technology can provide low-carbon emissions and a reliable, sustainable, and diversified energy supply. A resilient global nuclear power technology trade network can help meet the growing global energy demand and alleviate climate change. However, further in-depth research is needed on network resilience of nuclear power technology trade. In order to scientifically evaluate the network resilience of nuclear power technology, based on the import and export trade data of nuclear power technology from 2001 to 2022, 11 resilience indicators were constructed, and a grey statistical evaluation model was constructed to evaluate the network resilience of nuclear power technology globally, in 11 regions, and 32 countries. The results indicate that at global level, Germany and the United States have a more prominent position as significant trading countries in nuclear power technology, with diverse resilience indicators and unstable resilience in the global nuclear power technology network. At regional level, the nuclear power technology trade model has shifted from “intra-regional” to “inter-regional.” The resilience of Africa’s nuclear power technology network continues to be good, while the resilience of other regions’ is unstable. At national level, crucial nuclear power technology exporting countries are Russia, Germany, and the United States, while important nuclear power technology importing countries are France, China, and Ukraine. In addition, it is recommended that the trade structure of nuclear power technology should be optimized to improve the resilience of the national nuclear power technology network.
