【摘要】：《压水堆核电厂核安全有关的混凝土结构设计要求》(NB/T 20012—2010)中规定了压水堆核电站混凝土结构的构造要求,同《混凝土结构设计规范》(GB 50010—2010)中的规定基本相同。《美国核安全相关混凝土结构规范》(ACI 349-13)中亦有核安全相关混凝土结构的构造要求规定。以上述三本规范为基础,结合其他规范及手册,比较了中、美两国核电厂钢筋混凝土结构设计规范中关于混凝土保护层、钢筋锚固、钢筋连接、钢筋间距等构造方面的规定,便于设计、施工人员在国内在建AP1000三代核电站设计和施工中参考,以便设计、施工人员在保证安全的前提下进行材料替换等工作,也为国家标准《核电厂混凝土结构技术标准》的编制提供参考。从对比结果看,美国核电厂钢筋混凝土结构的构造要求是严于我国目前的核电厂规定的。
[Abstract]:The Design requirements for concrete structures related to Nuclear Safety of PWR Nuclear Power plants (NB/T 20012-2010) specify the structural requirements of concrete structures for PWR nuclear power plants. It is basically the same as that in the Code for Design of concrete structures (GB 50010-2010), and the requirements for the construction of nuclear safety related concrete structures are also contained in the Code for Nuclear Safety related concrete structures in the United States (ACI 349-13). Based on the above three codes, combined with other codes and manuals, this paper compares and compares the structural provisions of the code for the design of reinforced concrete structures of nuclear power plants in China and the United States concerning concrete cover, reinforcement Anchorage, reinforcement connection, steel bar spacing, etc. It is convenient to design, and the constructors refer to the design and construction of the AP1000 nuclear power station under construction in China, so that the design and construction personnel can carry out material replacement work on the premise of ensuring safety. It also provides a reference for the compilation of the National Standard of Nuclear Power Plant concrete structure Technical Standard. From the comparative results, the construction requirements of reinforced concrete structures of American nuclear power plants are strict than those of nuclear power plants in China.
