Oklo to collaborate with Atomic Alchemy on isotope production
Fast reactor developer Oklo, which recently went public on the New York Stock Exchange, announced on May 13 that it has signed a memorandum of understanding with Atomic Alchemy to cooperate on the production of radioisotopes for medical, energy, industry, and science applications.

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.
