Abstract

MANCINTAP is a parallel computational tool developed and maintained by Ansaldo Nucleare since 2011 to perform 4D neutron transport, activation and time-resolved dose-rate calculations in complex geometries for CPU-intensive applications. MANCINTAP creates an automated link between the 3D radiation transport code MCNP5—which is used to evaluate both the neutron fluxes for activation calculations and the resulting secondary photon dose rates—and the zero-dimensional activation code Anita2000 by handling crucial processes such as data exchange, determination of material mixtures and generation of cumulative probability distributions. Ansaldo Nucleare recently developed a new version of the tool, named MANCINTAP 2.0. A brief description of the computational tool is given here, with particular emphasis on the key technical choices underlying the project. The main enhancement is here highlighted with respect to the former version, and the results of a benchmarking campaign of MANCINTAP 2.0 against the Monte Carlo code FLUKA are described for two test cases.

Notes

  1. The class structure was designed with a modular pattern, with general and dedicated classes handling the main process and the I/O operations, respectively, with the goal of eventually allowing a multiple choice of activation kernels and/or transport codes.

  2. Except for user I/O and logging operations.

  3. Note that the MCNP5 v. 1.4 was used for the benchmark activities presented in this paper. That’s why the corresponding default ENDF/B-VI dataset libraries were used.
