GSS utililzes international best practices to conduct vital area identiciation/target set identification.For Vital Area and Target Set Identification a sabotage logic model is first created for various sequences that could lead to significant core damage. From the sabotage logic model, targets are evaluated based on the adversary’s capabilities (DBT). From the sabotage logic model targets, an Area Logic model is created to identify locations on the site where the targets / mitigating systems can be disabled. The Area Logic model is then used to create ‘candidate Vital Areas’. Each candidate Vital Area will be evaluated by Security to determine adequacy and core damage preventability of each candidate Vital Area
