General requirements for pressure-retaining systems and components in CANDU nuclear power plants/Material Standards for reactor components for CANDU nuclear power plants

1 Scope 1.1 This Standard specifies the technical requirements for the design, procurement, fabrication, installation, modification, repair, replacement, testing, examination, and inspection of, and other work related to, pressure-retaining systems, components, and supports over the service life of a CANDU nuclear power plant. 1.2 This Standard applies to all pressure-retaining systems, including their components and supports, in a CANDU nuclear power plant. 1.3 This Standard applies to containment components, but does not apply to concrete containment structures. 1.4 This Standard does not apply to portable assemblies of pressurized items that are temporarily connected to a system or component to enable testing, venting, draining, calibration, or other maintenance activities, provided that they (a) do not reduce the ability of a system to perform its design safety function; (b) are under surveillance when connected and are removed upon completion of their function; and (c) are constructed to Standards deemed by the licensee to be suitable for the application. Note: Safety analysis, environmental qualification programs, or seismic qualification may be used to satisfy the conditions in this Clause.
