Contact GRANT About This Technology


Technology Marketing Summary

Idaho National Laboratory (INL) has created a novel method and apparatus for monitoring plutonium concentration during pyroprocessing to ensure that the refining process is efficient at collecting actinides. Unlike existing solutions, which require complex, time-consuming remote testing, this unique sensor is capable of providing real-time in-situ measurements.

Description

An apparatus for real-time, in-situ monitoring of actinide ion concentrations which comprises a working electrode, a reference electrode, a container, a working electrolyte, a separator, a reference electrolyte, and a voltmeter. The container holds the working electrolyte. The voltmeter is electrically connected to the working electrode and the reference electrode and measures the voltage between those electrodes. The working electrode contacts the working electrolyte. The working electrolyte comprises an actinide ion of interest. The reference electrode contacts the reference electrolyte.
The reference electrolyte is separated from the working electrolyte by the separator. The separator contacts both the working electrolyte and the reference electrolyte. The separator is ionically conductive to the actinide ion of interest. The reference electrolyte comprises a known concentration of the actinide ion of interest. The separator comprises a beta double prime alumina exchanged with the actinide ion of interest.
