Abstract: The ocean is essential to country’s strategic interests and common destiny of mankind, and therefore equipment of various kinds is urgently needed for all-around and multi-dimensional ocean observation and exploration. This article brief introduced the two technological approaches of nuclear energy supply for underwater observation and exploration equipment and relevant exchange technologies of nuclear heat to electric power, quantitatively summarized the applicability of nuclear energy supply on all kinds of equipment, discussed the nuclear safety issues thereon, and then recommended that the technology research of radioisotope fabrication and separation and the construction of relevant facility, the development of individual reactor and the construction of relevant common facility, the technology research of thermoelectric conversion, and the research of relevant nuclear safety issues, should be special supported.

Abstract: Rare earth elements are widely identified as critical raw materials to underpin high-end technological innovation and the development of emerging industries, which makes them as important strategic minerals deserved by key international great powers. Since 2011, the United States and other developed nations are quickly fostering the development of their supply chains and industrial ecosystems of rare earth out of China’s engagement. Consequently, the new diversified supply pattern of rare earth has been formalizing at global level. Under this full supply chain view, this study performs a deep-dive analysis of international rare earth industry landscape changes in the key stage from mining, refinery, throughout to final recycling. Meanwhile, their future potential changes are further explored to provide the key implications for China’s rare earth industry to structure their global strategies.
