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.

Experiments performed at the Battelle Research Reactor indicate that the output of electrical components is influenced by a radiation environment in several ways. Gamma radiation produces electron emission from metals, varying from 0.38 × 10−16 A/cm2per R/h for aluminum to 6.1 × 10−16 A/cm2 per R/h for uranium. The gammas also ionize residual gas in the experiment test section and produce heating in the components. Thermal neutrons affect electrical components principally through reactions leading to the emission of beta particles. Fast neutrons and electrons (from various sources) sputter atoms from the surface of materials. The resistance of insulators may be drastically altered in a radiation field, principally by photoconduction. The magnitude of several of these effects of radiation is illustrated by a simple inpile experiment.
