scope:

This Standard specifies requirements for the material, analysis and design, construction, fabrication, inspection, examination, and aging management of nuclear safety-related structures. Nuclear safety-related structures covered in this Standard are

a) structures that support, house, or protect safety systems in nuclear power plants;

b) structures or their elements, where failure of the structures or their elements, would impede the function of safety systems;

c) structures and their elements that are required for the safe operation and/or safe shutdown of the reactor in nuclear power plants;

d) structures for the storage of wet irradiated fuel; and

e) structures for the storage of dry irradiated fuel and other radioactive waste material as agreed with the AHJ.

Notes:

1) Not all elements of the structures described in Item e) are necessarily considered safety-related and therefore such elements are not governed by this Standard.

2) The structures described in Item e) can include, but are not limited to structures for storage of high-level radioactive waste material, where "high-level" is as described in Clause A.7 of CSA N292.0, and where the structure requires a design life greater than 50 years.

This Standard does not apply to concrete containment structures covered in the CSA N287 series or the pressure-retaining systems and components covered in CSA N285.0/N285.6.

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.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
