A nuclear reactor attaining criticality means it has achieved a stable, self-sustaining nuclear chain reaction, where the neutron production equals losses. It is the normal, safe operating state where fuel sustains a fission reaction for power generation. Synonyms include reaching "first criticality," "startup," or achieving a "chain reaction".
