1.1  Structures, systems, and components requiring seismic qualification

This Standard defines the processes and requirements for performing seismic qualification by testing and presents the test methods that may be used for the seismic qualification of the nuclear power plant structures, systems, and components (SSCs). Seismic qualification by testing is typically used for SSCs that will be performing both an active function and that are required to change state during or following a seismic event in order to perform a safety function, while maintaining structural and/or pressure-boundary integrity or seismic category B per CSA N289.1 Clause 5.2.5.2. Seismic testing can identify contact chatter or unauthorized change of state of contact in electrical and I&C components during seismic excitation.

Notes:

(1)   Clause 5.3 of CSA N289.1 specifies acceptable seismic qualification methodologies, including qualification by analysis, testing, or a combination thereof and qualification by similarity, depending on the nature and complexity of the SSC.
(2)   Some mechanical and electrical components are inherently seismically rugged (see CSA N289.1 Clause 5.3.1.5 or Clause D.5 of this standard) and do not need to be tested to demonstrate seismic capability.
(3) Seismic categories are defined in N289.1, Clause 5.2.3.

1.2  Specification development

This Standard is intended to provide a basis for developing specifications for seismic qualification of SSCs by testing, or by a combination of analysis and testing, and to aid component purchasers, suppliers, and testing laboratories in selecting the appropriate test method(s) for performing a seismic qualification test. The specification provides the basis for the development of the test plan by the testing laboratory.

1.3  Acceptable methods

This Standard presents several acceptable methods with the intent of permitting the user to make a judicious selection from among the various options. In making such a selection, the user of this Standard should choose those test methods which best recognize the characteristics of a particular SSC and the seismic environment under which it is required to perform its function.

Notes:

It should be recognized that seismic qualification forms only a portion of the overall equipment qualification program. It is important that the qualification program for a component include consideration of all operational loadings (e.g., seismic, environmental, aging, thermal and mechanical stresses, deformation, etc.) for which the component must demonstrably meet its SSC functionality objectives.

Tests performed in accordance with the requirements of IEEE 344 and which satisfy the test specification written as per CSA N289.4 may be considered acceptable.

1.4  Terminology

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.

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.

1.1  Structures, systèmes et composants qui exigent une qualification parasismique

Cette norme définit les processus et les exigences pour effectuer la qualification sismique par des essais et présente les méthodes d’essai qui peuvent être utilisées pour la qualification sismique des structures, systèmes et composants (SSC) des centrales nucléaires. La qualification sismique par essais est généralement utilisée pour les SSC qui rempliront une fonction active et doivent changer d’état pendant ou après un événement sismique afin de remplir une fonction de sûreté, tout en maintenant l’intégrité structurelle et/ou l’intégrité des enveloppes sous pression ou la catégorie sismique B selon l’article 5.2.5.2 de la norme CSA N289.1. Les essais sismiques permettent d’identifier le broutage des contacts ou le changement non autorisé de l’état des contacts dans les composants électriques et les composants d’instrumentation et de commande pendant l’excitation sismique.

Notes :

(1)   L’article 5.3 de la norme CSA N289.1 précise les méthodologies de qualification sismique acceptables, y compris la qualification par analyse, par essais ou par une combinaison de ces méthodes et la qualification par similarité, selon la nature et la complexité du SSC.

(2)   Certains composants mécaniques et électriques sont intrinsèquement résistants aux séismes (voir l’article 5.3.1.5 de la norme CSA N289.1 ou l’article D.5 de la présente norme) et ne nécessitent pas de mise à l’essai pour démontrer leur capacité sismique.

(3)   Les catégories sismiques sont définies à l’article 5.2.3 de N289.1.

1.2  Élaboration des spécifications

La présente norme a pour objet de fournir une base pour l’élaboration de spécifications visant la qualification sismique des SSC par des essais, ou par une combinaison d’analyses et d’essais, et d’aider les acheteurs et fournisseurs de composants, ainsi que les laboratoires d’essais, à choisir la ou les méthodes d’essai appropriées pour réaliser un essai de qualification sismique. La spécification constitue la base de l’élaboration du plan d’essai par le laboratoire d’essai.

1.3  Méthodes acceptables

La présente norme présente plusieurs méthodes acceptables dans le but de permettre à l’utilisateur de faire un choix judicieux parmi les différentes options. Pour un tel choix, l’utilisateur de cette norme devrait choisir les méthodes d’essai qui tiennent le mieux compte des caractéristiques d’un SSC particulier et de l’environnement sismique dans lequel il doit remplir sa fonction.

Notes :

Il faut savoir que la qualification sismique ne constitue qu’une partie du programme global de qualification des équipements. Il est important que le programme de qualification pour un composant prenne en compte toutes les charges opérationnelles (p. ex., les contraintes sismiques, environnementales, le vieillissement, les contraintes thermiques et mécaniques, la déformation, etc.) pour lesquelles le composant doit prouver qu’il atteint ses objectifs de fonctionnalité.

Les essais réalisés conformément aux exigences de la norme IEEE 344 et qui satisfont aux spécifications des essais rédigés selon la norme CSA N289.4 peuvent être considérés comme acceptables.

1.4  Terminologie

Dans les normes CSA, le terme « doit » indique une exigence, c.-à-d. une prescription que l’utilisateur doit 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 de nature informative 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.

1.12

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.

This clause of part 1 is replaced by the following:

This International Standard deals with the safety of the following appliances, their RATED VOLTAGE being not more than 250 V for single-phase appliances, 480 V for other appliances and 24 V d.c. for appliances when battery operated:

– REFRIGERATING APPLIANCES for household and similar use;z
– ICE-MAKERS incorporating a motor-compressor and ICE-MAKERS intended to be incorporated in frozen food storage compartments;
– REFRIGERATING APPLIANCES and ICE-MAKERS for use in camping, touring caravans and boats for leisure purposes.

These appliances may be operated from the mains, from a separate battery or operated either from the mains or from a separate battery.

This standard also deals with the safety of ICE-CREAM APPLIANCES intended for household use, their RATED VOLTAGE being not more than 250 V for single-phase appliances and 480 V for other appliances.

It also deals with COMPRESSION-TYPE APPLIANCES for household and similar use, which use FLAMMABLE REFRIGERANTS.

This standard does not cover features of the construction and operation of those REFRIGERATING APPLIANCES which are dealt with in other IEC standards.

Refrigerating appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as

− REFRIGERATING APPLIANCES used in staff kitchen areas in shops, offices and other working environments
− REFRIGERATING APPLIANCES used in farm houses and by clients in hotels, motels and other residential type environments
− REFRIGERATING APPLIANCES used in bed and breakfast type environments, and
− REFRIGERATING APPLIANCES used in catering and similar non-retail applications 

are within the scope of this standard.

As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it does not take into account

– persons (including children) whose
• physical, sensory or mental capabilities or
• lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance.

NOTE 1 Attention is drawn to the fact that

– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary;
– in many countries, additional requirements are specified by national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities.

NOTE 2 This standard does not apply to

– appliances intended to be used in the open air;
– appliances designed exclusively for industrial purposes;
– appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);
– appliances incorporating a battery intended as a power supply for the refrigerating function;
– appliances assembled on site by the installer;
– appliances with remote motor-compressors;
