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.

Externally cooled fuel pins and internally cooled fuel tubes are compared for otherwise identical reactors. The tube design overcomes the deficiency of the pin design in fission-gas pressure venting. Fuel tubes have lower temperature differentials and thermal stresses than fuel pins. A greater number of smaller fuel tubes are required to replace fuel pins.
