The Radioisotope Power System Dose Estimation Tool (RPS-DET) is a software application created to simplify the process of designing, simulating, and analyzing ionizing radiation phenomena associated with RPS. RPS-DET leverages the SCALE nuclear software suite as a foundation for Monte Carlo particle transport, isotopic decay, source term generation, and data visualization. Users with or without radiation modeling experience can now use RPS-DET’s customizable, library-based architecture to select from multiple prewritten RPS designs and components, place them in various environmental scenarios — terrestrial, planetary, spacecraft, etc. — and specify fuel compositions and ages. The simulations can be used to estimate 3D instantaneous particle fluxes and dose rates or time-integrated fluences and doses generated by an RPS over a complex mission lifetime. Detailed information regarding RPS-DET and SCALE capabilities, applications, and resources can be found at the links below.
