Abstract
We describe the application of a Monte Carlo code for the simulation of active correlation measurements performed on uranium spheres of varying mass and enrichment. The measurements are performed on uranium metal using a DT neutron generator as the interrogation source, and a scintillation detector. The simulation is able to keep track of the neutron time of arrival, the pulse height, and the incident neutron energy. We show how this information can be used to determine the uranium mass and enrichment with increased sensitivity compared to previously studied methods.
