Description

We are developing a new approach for high sensitivity and real-time online measurements to monitor the kinetics in the processing of nuclear materials, specifically applied to nitrate/nitrite analysis related to the separation of Np and Pu for Pu-238 production. For the proof of principle, we plan to demonstrate rapid and continuous detection and identification of chemical species in aqueous and organic reactive systems using mid infrared (Mid-IR) quantum cascade laser (QCL) high-resolution spectroscopy. The QCL-IR method has been demonstrated by ORNL as a standoff technique with the capability for trace chemical detection and identification of surface residues and environmental gases with high sensitivity and selectivity. The innovation comes from demonstration of the capability of the Mid-IR QCL spectroscopy for the first time in the detection and identification of chemical processes in aqueous and organic solution. In this standoff or off-set method, the collection of a sample for analysis is not required. A flow cell is used for in situ sampling of a liquid slipstream. A deployable prototype has been designed based on attenuated total reflection (ATR) coupled with the QCL beam for hostile environments, radiological or chemical.

Qualifications

Faculty with experience in IR spectroscopy, FTIR, Raman, lasers, specifically quantum cascade lasers, and chemical kinetics could be very helpful to this project.
