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.

The results of in-pile tests on UO2 specimens of fine-grain and single-crystal structure led to the formation of a defect-trap theory to describe fission-gas release. The theory, which applies only when the UO2 temperature is below the grain growth region (≈1600° C), is described, and confirming experiments are cited. Experimental results are given to support the contention that a knock-out mechanism accounts for the majority of the fission-gas release at UO2 temperatures under 600° C. An oscillating experimental technique developed to evaluate the defect-trap theory is described, and the initial results are interpreted in terms of the theory.
