Nuclear
Nuclear Fuel Burnup Calculator
Calculates nuclear fuel burnup in MWd/kg from reactor power, operating time, and initial fuel mass. Used by reactor engineers to track fuel depletion, plan refueling cycles, and assess fuel performance limits.

Nuclear
Nuclear Criticality Calculator
Compute the effective neutron multiplication factor (k_eff) for a fissile system using the six-factor formula. Used by nuclear engineers to determine whether a reactor or fissile assembly is subcritical, critical, or supercritical.
