Nuclear Physics Calculators — Physics
Quantify radioactive processes and reactor behavior with physics-based tools. The decay chain calculator tracks parent-daughter activity over time, the decay heat calculator estimates residual thermal output after shutdown, and the neutron activation and reactor criticality tools model induced radioactivity and the multiplication factor. Each shows the underlying equation and assumptions, built for nuclear engineering students and professionals working from real half-life and cross-section data.
