Global Share of Scientific Publications Involving International Collaboration in Nuclear Energy and Engineering by Country

In 2023, Iceland led global collaboration in nuclear energy and engineering research, with 99.48% of its publications involving international partners. Generally, smaller nations like Iceland, Peru, and Luxembourg show higher collaboration rates compared to larger, more research-rich countries like the United States, Japan, and China, which reported notably lower shares—14.37%, 13.39%, and 9.51% respectively. This trend highlights the reliance of smaller countries on global partnerships to advance their research capabilities, as opposed to larger countries with more established local research infrastructures.

Future trends to watch include the potential for increased international collaboration as countries strive for innovation in the nuclear energy sector. There's an expectation that global challenges, such as climate change, will drive collaborative efforts further, influencing policy and funding to support cross-country research projects. Key players may look to leverage international expertise to meet emerging technical and regulatory challenges.
