CSA N290.15-10

Abstract

This Standard outlines a consensus approach to defining, implementing, and maintaining the safe operating envelope (SOE) at operating nuclear power plants. <br>This Standard applies to any nuclear power plant. Additional guidance is provided in Annex A for existing CANDU nuclear power plants. <br>In CSA standards, "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. <br>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. <br>Notes to tables and figures are considered part of the table or figure and may be written as requirements. <br>Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.
