Abstract

Read online

Ore deposits and nuclear reactors are greatly affected by the solubility and speciation of uranium at elevated (>100 °C) temperature. Here, the authors identify a new uranium chloride species (UCl4 0), which is mobile under reducing conditions, thereby necessitating a re-evaluation of uranium mobility.
