safety culture
안전 문화
That assembly of characteristics and attitudes in organizations and individuals which establishes that, as an overriding priority, nuclear plant safety issues receive the attention warranted by their significance. Coined by the International Nuclear Safety Advisory Group (INSAG) in its 1986 INSAG-1 report on the Chernobyl disaster, the term encapsulated the finding that the accident stemmed not merely from operator error but from systemic safety failures spanning design, regulation, and operations. Through INSAG-4 (1991) and INSAG-7 (1992), the concept expanded beyond the nuclear industry to become a foundational framework in industrial safety worldwide.
In depth
Origins: Chernobyl and INSAG
The term 'safety culture' first appeared in the International Nuclear Safety Advisory Group's 1986 report INSAG-1, prepared for the IAEA's Post-Accident Review Meeting on Chernobyl in Vienna. While INSAG-1 placed initial emphasis on operator error, it simultaneously introduced safety culture as a concept pointing to deeper organizational and institutional failures.
In 1991, the INSAG-4 report 'Safety Culture' addressed the concept as a standalone subject, establishing its formal definition. In 1992, INSAG-7 ('The Chernobyl Accident: Updating of INSAG-1') shifted the weight of its conclusions from operator actions to reactor design flaws, deficiencies in the regulatory regime, and a pervasive lack of safety culture throughout the Soviet nuclear industry.
Definition and Components
Per INSAG-4, safety culture is "that assembly of characteristics and attitudes in organizations and individuals which establishes that, as an overriding priority, nuclear plant safety issues receive the attention warranted by their significance." James Reason later decomposed safety culture into five subcultures: an informed culture, a reporting culture, a learning culture, a just culture, and a flexible culture.
Significance for Chernobyl
INSAG-7 concluded that the Chernobyl accident "flowed from deficient safety culture, not only at the Chernobyl plant, but throughout the Soviet design, operating and regulatory organizations." This diagnosis encompassed the absence of communication between designers and operators, the lack of feedback of operating experience, the lack of independent regulatory oversight, and an organizational culture in which production targets took precedence over safety.
