Nuclear Weapon Effects Calculator
This interactive tool illustrates the devastating blast effects of ground-level, shallow subsurface, and low-altitude nuclear weapon detonations.
Nuclear Fallout Calculator
You select the city, the wind speed, and wind direction and this tool will show you the fallout from the nuclear weapon blast.
Uranium Enrichment Calculator
How long does it take to enrich enough Uranium to make a nuclear weapon if one already has an enrichment cascade and consistently adds centrifuges to that cascade? This calculator estimates the number of days and years it would take to produce 50kg of highly-enriched (90% U235) Uranium.
