Safety Functions and Structural Design Requirements for Safety Significant Structures at the Savannah River Site W. N. Kennedy and J. R. Joshi Abstract Structural design of DOE facilities for Natural Phenomena Hazards (NPH) is performed on the basis of their performance category (PC). The PC levels are traditionally related to the functional classification (FC) of systems, structures and components (SSC). For General Services and Production Support structures, requirements are driven to national building codes whereas for Safety Class structures the requirements are driven to national consensus nuclear codes. For Safety Significant SSC,
