RPS dispersal in atmosphere during reentry creates radioactive aerosol which poses a significant radiological risk if inhaled or ingested.

Launch with RPS onboard required rigorous safety analyses and imposes imperative spacecraft design requirements Via cooperation with our partner, Stellar Nuclear provides nuclear and radiation safety analyses using the ESTE4Space tool and can prepare source terms and nuclide numerical dispersal and transport simulations relevant for potential credible accident scenarios and safety analysis report.

 Stellar Nuclear can provide impact assessment for future space missions with nuclear or radionuclide power sources.
