1.1 This Standard provides aging management requirements for concrete containment structures and their components for nuclear power plants and is directed to owners/operators, designers, manufacturers, fabricators, and constructors. Note: This Standard may provide guidance for aging management of other concrete structures where applicable. 1.2 This Standard provides requirements for aging management of existing concrete containment structures to address emerging challenges and ensure that existing concrete containment structures and their components satisfy their functional and performance requirements in all different phases of their life cycle. 1.3 This Standard provides requirements for aging management of new concrete containment structures to ensure that a) aging is addressed during design and construction phases; and b) containment structures and their components satisfy their functional and performance requirements in all different phases of their life cycle. 1.4 In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the standard.
