GSS applies internationally recognized best practices to conduct Vital Area and Target Set Identification for high-consequence facilities.
The process begins with development of a structured sabotage logic model to evaluate potential sequences that could lead to significant core damage. Targets are assessed based on the Design Basis Threat (DBT) and adversary capabilities.
From this analysis, an Area Logic Model is developed to identify site locations where target functions or mitigating systems could be disabled. These locations are evaluated as candidate Vital Areas and assessed for adequacy and the preventability of core damage.
Each candidate Vital Area is rigorously reviewed to ensure alignment with regulatory expectations and site-specific risk profiles.
