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.

Externally cooled fuel pins and internally cooled fuel tubes are compared for otherwise identical reactors. The tube design overcomes the deficiency of the pin design in fission-gas pressure venting. Fuel tubes have lower temperature differentials and thermal stresses than fuel pins. A greater number of smaller fuel tubes are required to replace fuel pins.
