The nuclear and radiation collection combines reactor-system simulation with radiation-protection and fuel-cycle calculations. It includes BWR and PWR educational simulators, decay heat, burnup and enrichment tools, dose and shielding calculators, and supporting radiation study material. These pages are educational and preliminary tools—not licensing, clinical or operational analysis software.
Choose a tool below by purpose. Individual pages include their own assumptions, equations, references and limitations where applicable.
