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.

Eight hundred fifty aluminum-10 wt% plutonium alloy fuel rods containing ∼55 kg of plutonium were fabricated by an injection casting process and encapsulated in Zircaloy-2 tubing. Casting was accomplished by inserting one end of a 0.610-in.-i.d. × 42-in.-long Pyrex glass mold into the molten alloy and then evacuating the mold. The diameter of the cast rods was 0.600 in. ± 0.001 in. with an average length of 38 in. Each element contained two or more of the fuel rods, totaling 47.75 in. in length. Unheated Pyrex molds produced higher quality castings than 1) unheated mild steel molds, 2) heated Pyrex molds, or 3) heated mild steel molds. Plutonium melt homogeneity was significantly improved by changing from intermittent melt stirring to continuous melt stirring prior to casting.
