The Multi-Isotope Process (MIP) Monitor is a nondestructive monitoring methodology to detect diversion and tampering of nuclear material at a reprocessing facility. The system measures the gamma-emitting isotopes in different stages of the reprocessing cycle through passive gamma spectroscopy. The indicators of isotopic distributions are measured and evaluated in near-real time by comparing measured spectra to expected, normal process spectra through multivariate analysis. The MIP monitor framework is compatible with medium resolution gamma detectors that can be easily deployed in an existing facility. In FY15, the MIP monitor was deployed at the H-Canyon Facility at Savannah River National Laboratory (SRNL) to develop and evaluate analysis algorithms for future in situ deployment. This paper discusses recent results from analysis of the data collected at SRNL. New results examine the preprocessing step of spectral alignment that is associated with the MIP monitor.
