ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

G7 pledges support for nuclear at Italy meeting
The Group of Seven (G7) recommitted its support for nuclear energy in the countries that opt to use it at a Ministerial Meeting on Climate in Italy last month.
In a statement following the April meeting, the group committed to support multilateral efforts to strengthen the resilience of nuclear supply chains, referencing the goal set by 25 countries during last year’s COP28 climate conference in Dubai to triple global nuclear generating capacity by 2050.

Four different concentrations of SmCl3 in LiCl-KCl were tested using cyclic voltammetry to determine the diffusion coefficients of Sm(III) and Sm(II) found to be 8.59 × 10−6 ± 1.67 × 10−6 and 8.01 × 10−6 ± 0.98 × 10−6 cm2 s−1, respectively. Ten samples, in the form of salt ingots with SmCl3 concentrations ranging from 0.5 to 10.0 wt% were used for the creation of three laser-induced breakdown spectroscopy (LIBS) calibration models corresponding to 484.4-, 490.5-, and 546.7-nm peaks. Results show that the 490.5-nm peak model had the lowest limit of detection at 0.510 wt%, and all three models had similar root-mean-square errors of calibration values ranging from 0.470 to 0.498 wt%. Four validation samples were then used to test the diffusion and LIBS methods’ ability to estimate concentration. The results of both methods match well with the inductively coupled plasma mass spectroscopy–measured concentrations.
