Official Release of The Radioisotope Power System Dose Estimation Tool (RPS-DET)

Abstract

The Radioisotope Power System Dose Estimation Tool (RPS-DET) is a software simulation application that serves as a one-stop shop for simulating and analyzing the radiation effects from radioisotope power systems (RPSs). RPS-DET includes a graphical user interface that allows the user to select from multiple RPS designs, place them in various terrestrial, planetary, or deep-space environments, and customize the plutonium oxide (PuO2) fuel. These user selections are combined into an input file that is automatically sent to the SCALE software suite, where simulation-specific neutron and gamma source terms are written prior to performing a Monte Carlo particle transport process on the chosen geometries. Simulation results represent three-dimensional instantaneous particle fluxes and dose rates or time-integrated particle fluences or doses according to pre-defined, customizable responses. The literature regarding RPS-DET addresses the early development and methodologies of this effort, while this paper outlines the official release of the software, instructions for ordering, final features, and current design.
