General Atomics Electromagnetic Systems (GA-EMS) has completed the baseline design of a reactor and engine for a nuclear thermal propulsion (NTP) rocket and has successfully tested key reactor components under contract from the Defense Advanced Research Projects Agency (DARPA), the company announced on November 7. The work was performed under a Track A, Phase 1 contract for the Demonstration Rocket for Agile Cislunar Operations (DRACO) program; Phases 2 and 3 of DRACO could culminate in a demonstration of the nuclear-propelled spacecraft in cislunar space (the region between the Earth and the Moon) during fiscal year 2026.

The Nuclear Innovation Alliance (NIA), a Washington, D.C.–based nonprofit, has released a new report, Advanced Nuclear Reactor Technology: A Company Compendium, along with an update to its Advanced Nuclear Reactor Technology: A Primer, first published last September.

Both reports are meant to serve as resources for investors, reporters, policymakers, regulators, and others wanting to learn more about the different technologies and key players involved in the design, licensing, construction, and operation of advanced nuclear reactors.
