The International Nuclear Energy Research Initiative (I-NERI) is a research-oriented collaborative program that supports the advancement of nuclear science and technology in the United States and the world. Innovative research performed under the I-NERI umbrella addresses key issues affecting the future use of nuclear energy and its global deployment. The 2010 Nuclear Energy Research and Development Roadmap issued by the U.S. Department of Energy, Office of Nuclear Energy (DOE-NE), identifies these issues as high capital costs, safety, high-level nuclear waste management, and non-proliferation. Projects under the I-NERI program investigate ways to address these challenges and support future nuclear energy systems. To attain these objectives, I-NERI promotes bilateral scientific and engineering research and development (R&D) with other nations. U.S. researchers partner with international organizations, allowing for broader perspectives and faster results at reduced costs. A link to the program can be found on the NE website.1
