DOE RFI probes barriers to space reactor production
The Department of Energy is asking for industry input on the United States’ readiness to produce “up to four space reactors within five years,” according to a request for information that opened on Tuesday.
With a quick turnaround—the deadline for responses is May 5—the RFI asks for an assessment of gaps or challenges related to reactor design, long-lead-time components, and fuel allocation or production.

From 1945 to 1963, global superpowers conducted over 500 atmospheric nuclear tests, releasing widespread radioactive fallout into the environment. These tests exposed nearby communities, military personnel, and even distant populations to harmful radiation. The 1963 Limited Test Ban Treaty curtailed above ground testing, but the long term health impacts persist. Radioactive isotopes from fallout have been linked to increased rates of cancer, particularly thyroid cancer and leukemia, among affected populations, including the “Downwinders” living near US test sites.
