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.

Unal’s subcooled flow boiling bubble model is being used in the best-estimate light water reactor code RELAP5/MOD3. There is a significant discontinuity (by a factor of 2) in the condensation heat transfer coefficient from this model at 1 MPa, which can cause numerical problems in the code. The correlation has been modified (with the approval of Unal) to remove the discontinuity at 1 MPa and to replace it with a form that is continuous to three significant places at 1.1272 MPa.
