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.

A method is described that predicts the kinetic response of a circulating-water-cooled and -moderated reactor to large changes in reactivity. This response is displayed in the form of time histories of power, peak fuel plate temperature, energy, reactivity, and period. The validity of the method is verified by the agreement of calculated and experimental data when it is applied directly to the SPERT-IV reactor. The general applicability and usefulness of the method are illustrated by the analysis of the Air Force Nuclear Engineering Test Reactor. A comparison with SPERT-IV, a parametric study, and an accident evaluation are shown as sample results.
