Fires present a special risk to nuclear plants because they can knock out cables that control-room operators need to safely cool down a reactor. N293-12 - Fire Protection For Nuclear Power Plants standard provides the minimum fire protection requirements for the design, construction, commissioning, operation and decommissioning of nuclear power plants (NPP), including structures, systems and components that directly support the plant and the protected area. This updated 2012 edition will enhance safety, provide an opportunity to reduce operational costs This standard is “technology neutral” and addresses the needs of a wider nuclear community by expanding its use to non-CANDU NPP technologies. This standard applies to plants in which requirements are referenced as a license condition by the nuclear regulator

Preface This is the fourth edition of CSA N293, Fire protection for nuclear power plants. It supersedes the previous editions published in 1987, 1995, and 2007. Scope 1.1* This Standard provides the minimum fire protection requirements for the design, construction, commissioning, operation, and decommissioning of nuclear power plants, including structures, systems, and components (SSCs) that directly support the plant and the protected area. 1.2* External events such as an aircraft crash or terrorist attack are outside the scope of this Standard. 1.3 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; \"may\" is used to express an option or that which is permissible within the limits of the standard; and \"can\" is used to express possibility or capability. 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. 1.4 The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
