The Multi-Isotope Process (MIP) Monitor combines gamma spectroscopy and multivariate analysis for online monitoring of nuclear reprocessing facilities.  The MIP Monitor evaluates the distribution of a suite of isotopes present in feed, product, and waste streams to detect deviations from nominal operation. Multivariate analysis methods common in chemometrics, such as principal component analysis and partial least squares regression, act as pattern recognition techniques, which can detect small deviations from the expected, nominal condition.   By targeting gamma-emitting indicator isotopes, the MIP Monitor approach is compatible with the use of small, portable, relatively high-resolution gamma detectors that may be easily deployed throughout a new or existing facility.  Researchers at Pacific Northwest National Lab have developed the MIP Monitor and applied it to simulated spectra representative of light water reactor fuel reprocessing and to bench-scale testbeds.  This presentation will give an overview of the MIP Monitor concept and present the results to date.
