Numerical simulation of plutonium measurements using an active well coincidence counter (AWCC)

Abstract

The article presents the results of a mathematical Monte-Carlo simulation of the passive mode of an active well coincidence counter (AWCC) in the Serpent software environment. The developed model was experimentally tested on different types of neutron sources. Estimates show that the results of the numerical simulation in the Serpent software environment can be used to refine and expand the range of effective mass measurements for ²⁴⁰Pu by adjusting the calibration coefficients.
