According to the Korean long-term plan for nuclear technology development, KAERI is conducting a R&D project on the partitioning and transmutation (P&T) of long-lived radionuclides. The study for the partitioning is focused on the development of pyroprocessing based on an electrorefining of actinides because it is a kind of proliferation-resistive technology, where all the transuranic metals ar...

In this paper, I study industry-university relations in a principalagent framework. Following the existing literature, these relations are interpreted in two ways: (1) as occurring through spillovers of knowledge among different groups of researchers, working for different institutional settings; or (2) as more formal interactions, through the possibility, for a scientist, to directly respond t...

Double beta decay is a very rare nuclear decay process in nature characterized by changing the ordering number Z by two units and leaving the massnumber A constant. It can occur in two modes, with the emission of two electrons and two anti-neutrinos or the emission of two electrons only. While the first mode is in agreement within the Standard Model, the neutrino-less double beta decay is not. ...

The relationship between research productivity and economic growth is the subject of information science which deals in this study to examine the impact of number of publications, research & development (R&D) expenditures and researchers involved in R&D activities on economic growth in the World’s largest regions for the period of 1980–2011. The study further expanded the research-growth nexus ...
