Inkjet droplets of radioactive material enable quick, precise testing at NIST
Researchers at the National Institute of Standards and Technology have developed a technique called cryogenic decay energy spectrometry capable of detecting single radioactive decay events from tiny material samples and simultaneously identifying the atoms involved. In time, the technology could replace characterization tasks that have taken months and could support rapid, accurate radiopharmaceutical development and used nuclear fuel recycling, according to an article published on July 8 by NIST.

Analyses were performed by using the U. S. advanced liquid metal reactor (ALMR) core design to determine the feasibility of using it as a 99Tc burner while reducing the sodium void reactivity effect (SVRE). A layer of 99Tc of variable thickness was inserted around the core midplane in rows 2 through 5, and all blanket assemblies were replaced with fuel assemblies. The results indicate that a core with a 34-cm-thick layer in rows 2 through 5 has the optimum characteristics of SVRE, 99Tc destruction rate, and fuel enrichment.
