Draft Amendment to C22.1

1.1 General

This Standard sets forth the general requirements for seismic design and qualification of nuclear power plants (NPPs).

Note: This Standard also provides guidance for preparing a seismic qualification governance document (see Clause 5.3.7).

1.2 Application

This Standard applies to all structures, systems, and components (SSCs) of NPPs requiring seismic qualification based on nuclear safety considerations (see Annex A). This Standard may also be applied to other SSCs, as deemed appropriate by the operating organization or by the authority having jurisdiction (AHJ) such as the Canadian Nuclear Safety Commission (CNSC).

1.3 Seismic hazard level for NPPs

This Standard was developed for NPPs in regions of low to moderate seismic hazard, comparable to the levels near Canada’s existing NPPs. In regions of higher seismic hazard, the engineering required for reliable design under strong earthquake shaking is more complex, and is beyond the scope of this Standard. Therefore, while the provisions of this Standard can be applied to any NPP site, additional provisions can be required for high seismic hazard sites.

1.4 Application to other nuclear facilities

This Standard may be applied, as appropriate, to nuclear facilities under the jurisdiction of the Nuclear Safety and Control Act.

1.5 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.

1.6  Terminology – “shall consider”

In this Standard, “shall be considered” or “shall consider” means that the user evaluates the impact and documents any decisions.

1.1 Généralités

Cette norme énonce les exigences générales relatives à la conception et à la qualification parasismique des centrales nucléaires.

Note : Cette norme présente également des directives pour préparer un document de gouvernance pour une qualification parasismique (voir l’article 5.3.7).

1.2 Mise en application

Cette norme s’applique à toutes les structures, tous les systèmes et tous les composants (SSC) des centrales nucléaires qui nécessitent une qualification parasismique pour des raisons de sûreté nucléaire (voir l’annexe A). Elle peut aussi s’appliquer à d’autres SSC, si cela est jugé pertinent par l’exploitant ou par l’autorité compétente, comme la Commission canadienne de la sûreté nucléaire (CCSN).

1.3 Niveau de risque sismique des centrales nucléaires

Cette norme s’applique aux centrales nucléaires des régions à risque sismique faible à moyen, comparable aux niveaux qui existent près des centrales nucléaires existantes du Canada. Dans les régions qui présentent un plus grand risque sismique, les travaux d’ingénierie requis pour une conception saine pouvant résister à de fortes secousses sismiques sont plus complexes et dépassent le cadre de cette norme. Donc, bien que cette norme puisse s’appliquer à tout site de centrale nucléaire, des exigences supplémentaires pourraient être requises pour les sites à plus grand risque sismique.

1.4 Mise en application relative aux autres installations nucléaires

Cette norme peut s’appliquer, s’il y a lieu, aux installations nucléaires visées par la Loi sur la sûreté et la réglementation nucléaires.

1.5 Terminologie

Dans cette norme, le terme « doit » indique une exigence, c’est-à-dire une prescription que l’utilisateur est obligé de respecter pour assurer la conformité à la norme; « devrait » indique une recommandation ou ce qu’il est conseillé, mais non obligatoire de faire; et « peut » indique une possibilité ou ce qu’il est permis de faire.

Les notes qui accompagnent les articles ne comprennent pas de prescriptions ni de recommandations. Elles servent à séparer du texte les explications ou les renseignements qui ne font pas proprement partie de la norme.

Les notes au bas des figures et des tableaux font partie de ceux-ci et peuvent être rédigées comme des prescriptions.

Les annexes sont qualifiées de normatives (obligatoires) ou d’informatives (facultatives) pour en préciser l’application.

1.6  Terminologie – « doit prendre en compte »

Dans cette norme, les expressions « doit être pris en compte » et « doit prendre en compte » signifient que l’utilisateur évalue les conséquences de ses décisions et les met par écrit.

This part of IEC 60974 specifies safety and performance requirements for industrial and professional equipment used in arc welding and allied processes to feed filler wire.

This document is applicable to WIRE FEEDERS and to WIRE-FEED CONTROLS that are stand-alone (separate from the welding equipment), housed together in a single enclosure or housed in a single enclosure with other welding equipment. The WIRE FEEDER can be suitable for manually or mechanically guided torches.

This document is not applicable to spool-on torches, which are covered by IEC 60974-7.

NOTE 1 Typical allied processes are electric arc cutting and arc spraying.

NOTE 2 This document does not include electromagnetic compatibility (EMC) requirements, which are given in IEC 60974-10.

The CSA N291 standard provides requirements for nuclear safety related structures. The scope of the standard has somewhat evolved as described below.

The first edition (2008) of the standard included within its scope the structures and components of CANDU NPPs that support, house or protect nuclear safety systems and are required for the safe operation and shutdown of the reactor. The scope has also included the facilities for the storage of irradiated fuel and other radioactive waste material. The intent of this was to be broad and all encompassing, and to allow for the operating organization to determine the applicability of the standard to their structure, as agreed by the AHJ. 

Clarification of the scope with regards to radioactive waste storage structures was provided in the second edition (2015) to ensure that the users understood that the standard applies to the storage of wet and dry irradiated fuel. The scope statement in the second edition clarified that the storage of other radioactive waste was to be included for facilities as agreed by the AHJ.

In the third edition (2019), the requirement of ‘dry irradiated fuel’ was refined from a generic inclusion, to include those that are required as agreed with the AHJ. Dry irradiated fuel was moved to item e) and included with other radioactive waste material. The use of “as agreed by with the AHJ” means that the AHJ and the operating organization can agree to use other standards besides CSA N291 for the structures listed in item e). Notes were added to clarify that not all elements of the structures described in item e) are considered safety-related, and to provide additional guidance on the storage of other radioactive waste with reference to CSA N292 with respect to “high-level” waste.

In the 2019 edition, the scope of the standard has been broadened to apply to any nuclear safety-related structures not only those within NPPs.

CSA N291 énonce les exigences relatives aux enceintes liées à la sûreté des centrales nucléaires. Le domaine d’application de la norme a quelque peu évolué, comme suit :

La première édition (2008) de la norme comprenait dans son domaine d’application les structures et les éléments des CN CANDU qui supportent, abritent ou protègent les systèmes de sûreté des centrales nucléaires et qui sont requis pour le fonctionnement et l’arrêt sécuritaire du réacteur. Le domaine d’application a également intégré les installations liées au stockage du combustible irradié et d’autres déchets radioactifs. L’objectif était d’être vaste et exhaustif, et de permettre à l’exploitant de déterminer l’applicabilité de la norme à sa structure, comme convenu avec l’AC. 

Une clarification du domaine d’application en ce qui concerne les structures de stockage des déchets radioactifs a été fournie dans la deuxième édition (2015) pour s’assurer que les utilisateurs comprennent que la norme s’applique au stockage à sec ou en piscine du combustible irradié. L’énoncé du domaine d’application de la deuxième édition précisait que le stockage d’autres déchets radioactifs serait ajouté pour les installations, comme convenu avec l’AC.

Dans la troisième édition (2019), l’exigence relative aux « combustibles irradiés secs » en général a été précisée de manière à intégrer ceux qui sont requis comme convenu avec l’AC. Le combustible irradié sec a été déplacé à l’alinéa e) et intégré à d’autres déchets radioactifs. L’utilisation du terme « comme convenu avec l’AC » signifie que l’AC et l’exploitant ont la possibilité de convenir d’utiliser d’autres normes parallèlement à CSA N291 pour les structures énumérées à l’alinéa e). Des notes ont été ajoutées pour clarifier que tous éléments des structures décrits à l’article e) ne sont pas nécessairement considérés comme étant tous liés à la sûreté et pour fournir des renseignements supplémentaires sur le stockage d’autres déchets radioactifs en ce qui a trait aux déchets radioactifs « de haut niveau » énoncés dans CSA N292.

Dans l’édition 2019, le domaine d’application de la norme a été élargi de manière à s’appliquer à toutes les enceintes liées à la sûreté des centrales nucléaires et non seulement à celles se trouvant à l’intérieur des CN.
