SGH designed several Seismic Category I structures at the Comanche Peak nuclear facility for preparation of Combined Operating License Application (COLA). These reinforced concrete structures include the ultimate heat sinks (UHS), power source fuel storage vaults (PSFSV), and essential services water pipe tunnels (ESWPT). SGH analyzed the original structural configuration and seismic input, and reanalyzed and designed them four years later with revised geometry and loading.
