Patent ID: 8741119

Claim:
An apparatus for real-time monitoring of actinide ion concentrations in molten salts, comprising: a) a working electrode, a reference electrode, a container, a working electrolyte, a separator, a reference electrolyte, and a voltmeter; b) said working electrolyte comprising an actinide ion of interest; c) said container holding said working electrolyte; d) said separator separating and contacting said working electrolyte and said reference electrolyte; e) said working electrolyte contacting said working electrode; f) said separator ionically conductive to said actinide ion of interest; g) said reference electrode contacting said reference electrolyte; h) said reference electrolyte comprising said actinide ion of interest with a known concentration; i) said separator comprising beta double prime alumina exchanged with said actinide ion of interest; j) said voltmeter electrically connected to said working electrode and said reference electrode; and k) said voltmeter having a means for measuring the voltage between said working electrode and said reference electrode; and l) said voltmeter having a means for indicating the concentration of said actinide ions of interest within said working electrolyte.
