Neutron Flux

The intensity of neutron radiation passing through a given area per unit time, typically measured in neutrons per square centimeter per second (n/cm²/s). In fusion reactors, neutron fluxneutron fluxneutron flux is a critical design parameter: high D-T fusionneutron fluxMeV degrades structural materials (neutron embrittlement) and activates reactor components. D-T fusion produces 14.1 MeV neutrons that require shielding and regular maintenance.
