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.
