N2 - The interpretation of subcritical source-driven noise analysis measurements had previously relied upon the use of point reactor kinetic models to relate the measured quantities to the neutron multiplication factor keff. Monte Carlo codes have been developed that can directly simulate the source-driven noise analysis measurement in the same manner in which the measurement is performed. The Monte Carlo codes can be used to interpret the measurements to determine the subcritical neutron multiplication factor using a perturbation technique that has been analytically developed. This paper demonstrates how source-driven subcritical noise analysis measurements with a highly enriched uranyl nitrate solution system are interpreted using the Monte Carlo technique. The measurements were interpreted using a variety of perturbations with several nuclear cross section data sets to demonstrate that the interpretation methodology is not significantly dependent on the perturbation and does not depend significantly on the nuclear cross section data. The largest difference among the interpreted keff values is 0.003 for the nuclear cross section data sets used in this analysis.
