Nuclear
Nuclear Waste Activity Calculator
Estimates the remaining radioactive activity of nuclear waste after a given storage period, accounting for radioactive decay and a safety reduction factor. Essential for disposal planning and regulatory compliance timelines.

Nuclear
Nuclear Reactor Period Calculator
Estimate the effective reactor period — the e-folding time of power change — from measured power levels, reactivity, and prompt neutron lifetime. Used by reactor operators and nuclear engineers during startup, shutdown, and transient analysis.
