Draft Scope/Description:

1.1 General

This Standard specifies requirements for the design of concrete containment structures , and addresses their beyond design basis assessment. Concrete containment structures include the following structural and non-structural elements:

a) concrete;

b) reinforcement (pre-stressed and non-pre-stressed);

c) steel (e.g., liner, embedded parts, anchors);

d) non-metallic liners and coating systems;

e) joint sealants and water stops; and

f) elements necessary to support the containment structure (e.g., foundations).

 

1.2 Application

This Standard is used in concert with the other standards of the CSA N287 series of Standards.

 

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/operating organization and the AHJ.

1.3 Terminology

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.
