Radiant signs contract on microreactors for the military
California-based microreactor developer Radiant Industries has announced the signing of what it calls “the first-ever agreement” to deliver a mass-manufactured nuclear microreactor to a U.S. military base. The contract was signed with the Department of Defense’s Defense Innovation Unit (DIU) and the U.S. Air Force as part of the Advanced Nuclear Power for Installations (ANPI) program.

Materials and fin-tube geometry have a large influence on the ultimate size and mass of a waste-heat radiator for use in space. In turn, many factors, such as meteoroid damage protection, structural integrity, vehicle integration, and fluid compatibility, influence the requirements for materials and geometry. A wide variety of materials and geometries can be considered.
