Now, NASA, DOE, and the White House want nuclear power to play a much larger role in space exploration as plans take shape for a sustained human presence on the Moon and subsequent crewed journeys to Mars……….

Among the participants was Rep. Bill Foster (D-IL), a former Fermilab physicist, who argued that proceeding with HEU  (  Highly Enriched Uranium)would set a dangerous precedent. “If all of the spacefaring nations start using HEU reactors in space, then this would involve utilization of a significant amount of weapons grade material,” he remarked…….

Alan Kuperman, a policy scholar affiliated with the Nuclear Proliferation Prevention Project, pointed to U.S. efforts since the 1970s to minimize the use of HEU in civilian applications, arguing they are “based on the logic of no exceptions.”

“If we say, ‘well, we’re going to have exceptions,’ then other countries are going to say, ‘well, we want exceptions too,’ and then the whole thing falls apart,” he remarked……..https://www.aip.org/fyi/2020/us-ramps-planning-space-nuclear-technology
