This Code covers the design and construction of concrete structures that form part of a nuclear facility and that have nuclear safety-related functions, but does not cover: i) Concrete reactor vessels and concrete containment structures, as defined by Joint ACI-ASME Committee 359; or ii) Steel-plate composite walls and steel-plate composite slabs, as defined by AISC-N690 Technical Committee 12.The structures covered by this Code include concrete structures inside and outside the containment system.
This Code may be referenced and applied subject to agreement between the owner and the Regulatory Authority.All notation sections have been removed from the beginning of each chapter and consolidated into one list in Chapter 2.The format of this Code is such that it depends on the “Building Code Requirements for Structural Concrete (ACI 318-08) and Commentary” and any applicable errata issued up to September 2011, and should be used in conjunction with that Code and applicable issued errata.
The Commentary, which is presented after the Code, discusses considerations of ACI Committee 349 in developing, “Code Requirements for Nuclear Safety-Related Concrete Structures (ACI 349-13).” This information is provided in the Commentary because this Code is written as a legal document and, therefore, cannot present background details or suggestions for carrying out its requirements.
For design of nuclear structures, in cases of conflict between this Code with other documents, except wherever this Code is in conflict with the specific requirements of the authority having jurisdiction (AHJ), ACI 349 shall govern. The materials, processes, quality control measures, and inspections described in this Code should be tested, monitored, or performed as applicable only by individuals holding the appropriate ACI Certifications or equivalent.
