GAIN Consultation
DOE-NE accepts applications focused on innovation that support the broader NE mission, which includes production and utilization of nuclear energy produced from fission (e.g., for increased generation of electricity, supply of process heat, synthetic fuels or chemicals production, etc.) in the following general topic areas:
- Analysis and evaluation of, and for, advanced reactor concepts and associated designs, including development of research and development (R&D)-based licensing, technical requirements, or regulatory strategies
- Analysis, evaluation, and technology development of fission reactors for space, maritime or defense applications
- Use of artificial intelligence to accelerate development and deployment of nuclear technologies, especially advanced reactors
- Advanced tools and methods to enhance in-situ recovery mining technologies
- Advanced nuclear fuel development, fabrication, and testing (including fuel materials and cladding)
- Development of improved methods and technologies for spent nuclear fuel and high-level waste management
- Advanced separation technologies for the recycle and reuse of valuable nuclear materials
- Assessment of concepts and approaches and technology for material control and accounting (MC&A), safeguards against proliferation, and security risks
- Structural material and component development, testing, and qualification
- Development, testing, and qualification of instrumentation, controls, and sensor technologies that are hardened for harsh environments and secured against cyber intrusion
- Modeling and simulation, nuclear applications of high-performance computing, codes, and methods
- Technical assistance from subject matter experts and/or data/information to support technology development and/or assessment of key technical or licensing issues.
