"This Code provides minimum requirements for design and construction of nuclear safety-related concrete structures and structural members for nuclear power generating stations. Safety-related structures and structural members subject to this standard are those concrete structures that support@ house@ or protect nuclear safety class systems or component parts of nuclear safety class systems. Specifically excluded from this Code are those structures covered by ""Code for Concrete Reactor Vessels and Containments@"" ASME Boiler and Pressure Vessel Code Section III@ Division 2@ and pertinent General Requirements (ACI 359). This Code includes design and loading conditions that are unique to nuclear facilities@ including shear design under biaxial tension conditions@ consideration of thermal and seismic effects@ and impact and impulsive loads. For structural concrete@ fc??hall not be less than 17 MPa@ unless otherwise specified. This Code shall govern in all matters pertaining to design and construction of reinforced concrete structures@ as defined in 1.1.1@ except wherever this Code is in conflict with the specific provisions of the authority having jurisdiction (AHJ). This Code shall govern in all matters pertaining to design@ construction@ and material properties wherever this Code is in conflict with requirements contained in other standards referenced in this Code. For special structures@ such as arches@ tanks@ reservoirs@ bins and silos@ blast-resistant structures@ and chimneys@ provisions of this Code shall govern where applicable. Intentionally left blank. Intentionally left blank. Concrete on steel form deck Design and construction of structural concrete slabs cast on stay-in-place@ noncomposite steel form deck are governed by this Code. This Code does not govern the design of structural concrete slabs cast on stay-in-place@ composite steel form deck. Concrete used in the construction of such slabs shall be governed by Chapters 1 through 7 of this Code@ where applicable. Special provisions for earthquake resistance?? Provisions of Chapter 21 shall be satisfied. See 21.2.1."
