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 evaluation of electromagnetic (EM) loads acting on conductive structures is one of the critical problems for tokamaks. This paper focuses on the main conductive components of the Chinese Fusion Engineering Test Reactor (CFETR), which are vacuum vessel (VV) and blanket components. A multiscenario EM load-calculating simulator is developed. The simulator adopts circuit equations for the calculation of eddy current, magnetic field, and resulting EM loads acting on the VV. And for EM loads acting on the blanket components, an integral parameter method is applied. With the circuit equations and pre-obtained integral parameters implanted in the simulator, EM loads on the CFETR VV and blankets at different scenarios can be evaluated quickly. Results indicate that the simulator can be conveniently used for multiscenario and real-time EM assessment of the tokamak VV and blanket components.
