Design Bases Specifications are facility-specific. They restate Design Requirements into statements that specify what your unique facility or plant will do to comply with a specific requirement. They are as made as specific as possible and still address how the requirement is met by the facility as whole, not by the system, component or structure.

Note that general requirements can often produce very complex and convoluted Design Bases Specifications necessary to specify the range of plant systems and configurations necessary to comply with the requirement. In the past, these complex conditional statements would be found in the Final Safety Analysis Report (FSAR) or similar document, but in the Williamson-Merritt Taxonomy, these descriptions are incorporated as Design Bases Specifications to provide specific design guidance for your installation.
