Nuclear
Nuclear Emergency Response Calculator
Estimates the required emergency planning zone radius during a nuclear incident based on release amount, wind speed, atmospheric stability, evacuation time, and population density. Use it for emergency preparedness drills and regulatory zone planning.

Nuclear
Nuclear Criticality Safety Calculator
Estimates the criticality safety margin for fissile material configurations by computing an effective neutron multiplication proxy based on concentration, geometry, moderator ratio, reflector thickness, and temperature. Used by nuclear safety engineers to assess subcriticality margins.
