本标准涵盖了构成核电站一部分且具有核安全相关功能的混凝土结构的正确设计和施工，但不包括混凝土反应堆容器和混凝土安全壳结构（由ACI-ASME联合委员会359定义）。本规范涵盖的结构包括安全壳系统内外的混凝土结构。根据业主和监管机构之间的协议，可以引用和应用本规范。从每章开头删除所有注释部分，并将其合并到第2章的一个列表中。 本规范的格式基于“结构混凝土建筑规范要求（ACI 318-08）”，并包含该标准的最新修订版。该评论在准则之后发表，讨论了ACI 349委员会在制定“核安全相关混凝土结构规范要求（ACI 349-13）”时的一些考虑事项评注中提供了这些信息，因为该准则是作为法律文件编写的，因此不能提供背景细节或执行其要求的建议。

This standard covers the proper design and construction of concrete structures that form part of a nuclear power plant and that have nuclear safety-related functions, but does not cover concrete reactor vessels and concrete containment structures (as defined by Joint ACI-ASME Committee 359).The structures covered by the 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 based on the "Building Code Requirements for Structural Concrete (ACI 318-08)" and incorporates recent revisions of that standard.The commentary, which is presented after the Code, discusses some of the 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 the Code is written as a legal document and therefore cannot present background details or suggestions for carrying out its requirements.
