| Summary/Abstract |
In this study, we investigated the changes in those technologies over time in the United States, European countries, Japan, and China, all of which have led the global nuclear energy industry. Using clustering analysis based on the patents that were applied to those regions from 1972 to 2014, we first identified 15 technological topics in nuclear waste management. Next, using technology network analysis, we examined the changes in these topics over time. The results show that regional conditions such as the history related to nuclear weapons, type of ideology, geological condition, resource situation, and international affairs are critical factors that influence the trends in nuclear waste treatment technologies. We revealed that majority of technology development is concerned long-term storage. This method can be useful for both the advanced countries and the latecomers. However, as the long-term storage is not final step in nuclear waste management, those late comers should gain technological competence for nuclear waste management by not only in-house R&D but also open innovation via licensing or joint R&D with the advanced countries to complete technologies for overall life-cycle of nuclear energy.

| Summary/Abstract |
There are several technical, institutional and geopolitical challenges facing an expanded nuclear industry in the twenty-first century. This article addresses some of the security concerns that are linked to the expansion of nuclear power in the world. Given that more and more states are going to have access to sensitive nuclear technology and material, the security concerns surrounding nuclear energy are bound to increase. However, in the absence of a satisfactory nuclear waste management solution and adequate regulatory protocols, a large-scale expansion of the civil nuclear sector will present significant security challenges. The adaptation of the fuel cycle to incorporate reprocessed spent nuclear fuel presents perhaps the most serious concern owing to the inherent relationship between reprocessing and nuclear proliferation. Of equal concern is the fact that existing international regimes are inadequate to deal with civilian nuclear-related issues in the twenty-first century.
