Description / Abstract:

This Standard provides general requirements for the design, fabrication, construction, installation, examination, and commissioning as well as the in-service examination, testing, and evaluation of reinforced (prestressed and non-prestressed) concrete containment structures for nuclear power plants designated as class containment. It is directed to the owners/operators, designers, manufacturers, fabricators, and constructors of the concrete components and parts.


1) This Standard is applicable to new nuclear power plants’ concrete containment structures to be built in Canada. Application of the Standard to concrete containment structures to be built outside Canada is subject to approval of the authority having jurisdiction (AHJ). The application of the Standard to existing or operating nuclear power plants is as agreed upon by the owner/operator and the AHJ.

2) The requirements of the CSA N287 series of Standards generally exceed the requirements of the National Building Code of Canada.

3) In Canada, CNSC RD-337 provides the regulatory requirements for the design of new containment structures.

This Standard defines the responsibilities of organizations and individuals with respect to the functions mentioned in Clause 1.1 together with the pertinent documentation required as a statement of quality assurance.

Note: A basic interaction organizational chart and basic interaction chart for documentation are provided in Annex A.

This Standard includes general requirements for metallic and nonmetallic parts, such as containment liners, anchorage systems, and appurtenances, that form part of the containment boundary and that are placed in their final position within the concrete or are attached to the concrete.

This Standard includes definitions that are applicable in this Standard and in the other Standards forming the N287 series of Standards.

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 (nonmandatory) to define their application.
