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.

The problem of controlling xenon-power spatial transients in a large thermal power reactor is formulated in terms of the dynamic programming formalism. This formulation results in a computing algorithm that can be used to select the control action that optimizes some performance index from among a predetermined set of allowable control sequences. An application of this formalism to a relatively detailed three-dimensional reactor model is presented.
