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.

An extended application of the FAPMAN planning model has been made to typical boiling water reactor (BWR) fuel loading and generation planning problems. The additional constraint on reactive fuel loading pertinent to BWRs was implemented, together with some improvements on the back-end fuel cycle economic model and the gradient projection method of searching for better generation plans. The flexibility of the FAPMAN planning tool has been demonstrated in numerical studies made in several degrees of optimization, for disposal or reprocessing options in the back end of the fuel cycle and for the bounded or free refueling cycle length.
