*REQUEST FOR INFORMATION* Space Reactor Industrial Base Assessment

The Department of Energy (DOE) is conducting a Space Reactor Industrial Base Assessment to identify gaps in the U.S. industrial base and recommend actions to close them. The assessment is mandated by National Science and Technology Memorandum 3 and supports DOE's mission to develop and enable the use of space nuclear power systems. The RFI solicits industry input to inform the assessment, focusing on constraints, production readiness, and government actions that would help. Key areas of interest include nuclear fuel, design capability, non-fuel core components, instrumentation and control, power conversion systems, and infrastructure capabilities. Respondents should address the areas relevant to their expertise and provide candid assessments, including commercially sensitive information where relevant. • The assessment covers the nuclear power unit, from the reactor core through the power conversion system. • The RFI is technology-inclusive, and respondents should describe their capability against the parameter bands provided. • The assessment team will maintain analytical independence, and individual company responses will not be shared with INL reactor development programs. • Responses should be submitted by email no later than May 5, 2026. • The final report will present findings in aggregate by subsystem area, without identifying companies unless they provide explicit written consent.
