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.

Capsule irradiations have been performed on single fast reactor fuel pins in a sodium environment under simulated loss-of-coolant-flow conditions. The main objectives were to determine the thresholds, modes, and mechanisms of fuel pin failures. The parameters were canning temperature and internal pin pressure. The loss-of-coolant-flow condition was simulated by adjusting midwall canning temperatures of ∼850 and ∼1000°C. The results indicated that creep rupture is the predominant failure mechanism at canning temperatures of 1000°C and gas pressures of above 40 bars. The failure mechanism of fuel pins tested at ∼850°C and gas pressures lower than 60 bars is probably cladding strain due to differential expansion of fuel and canning.
