Concentration probes for molten salt

The potential applicability of electrochemical methods such as normal pulse voltammetry to the on-line monitoring of actinide concentration in molten chlorides was reported by CRIEPI (Iizuka, 2001a). The device used consists of wire electrodes (W, Ta) and a reference electrode connected to a poten — tiostat. As shown by the linear relationship between the reduction current and concentration in Fig. 10.27, the applicability of electrochemical methods was demonstrated for concentrations of U or Pu in LiQ-KQ-UQ3-PuQ3 molten salt of up to 1.7 wt%.
