1.1 Inclusions

This Standard provides requirements for the design and qualification of components for the monitoring and display of NPPs and NPP facility irradiated fuel storage safety functions in the event of a design basis accident (DBA) or a design extension condition (DEC) during the operational phase of the facility lifecycle.

Notes:

This Standard applies only to the functions of plant systems, including safety systems and process control systems, associated with monitoring in the event of an accident; other monitoring functions are beyond the scope of this Standard.

The requirements for a DBA and those for a DEC might differ. Where requirements differ for a DBA and a DEC, the difference is explicitly stated.

General requirements and guidance regarding DECs [as a subset of beyond design basis accidents (BDBAs)] are covered in CSA N290.16.

The operational phase of the facility lifecycle would include the period of time wherein the reactor is capable of operations, generally from the end of commissioning with fuel loaded, through to the end of operations with fuel unloaded prior to decommissioning.

1.2 New and existing NPPs

This Standard applies to existing NPPs and new NPPs.

Notes:

The requirements for new plants and existing plants might differ. Where requirements differ for new plants and existing plants, the difference is explicitly stated.

For existing NPPs, the application should address the information in this Standard to the extent practicable. Any alternative approaches selected or mitigating measures applied should be identified.

This Standard may provide guidance for nuclear facilities other than NPPs, using a graded approach.

1.3 Application

This Standard applies to components and systems that enable NPP staff, in the event of an accident, to

monitor and display the plant safety functions for diagnosing that an accident, including severe accident, is occurring or has occurred;

Note: The purpose of monitoring the plant safety functions is to guide operator actions that might be required as a part of the accident response.

 

monitor and display plant conditions for the purposes of accident management to continuously address the state of safety functions; and

Note: Accident management refers to specific actions taken within the NPP during the evolution of an accident to prevent escalation, mitigate consequences, and to achieve a long-term controlled stable state. Accident management actions are the responsibility of the plant operator. Refer to CNSC REGDOC-2.3.2 for further clarification.

 

monitor and display parameters for the initiation of on-site and off-site emergency management to confirm the effectiveness of the accident management actions.

Notes:

Emergency management in this context refers to the overall coordinated response to, mitigation of, and recovery from a nuclear emergency. Emergency management is not concerned with the specific actions taken within the NPP to manage the accident (i.e., accident management as described above). Emergency management actions can be the responsibility of the operating organization or other jurisdictions
(e.g., operator emergency response organizations, government bodies, emergency workers). Refer to CSA N1600 for guidance on nuclear emergency categorization and notification.

If the emergency planning basis, as defined in CSA N1600, does not require off-site emergency management actions, any functions associated with monitoring off-site parameters may be excluded where justified.

 

1.4 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 (non-mandatory) to define their application.

1.1 Inclusions

Cette norme énonce les exigences relatives à la conception et à la qualification des composants pour la surveillance et l’affichage des fonctions de sûreté des centrales nucléaires et des installations de stockage du combustible irradié dans le cas d’un accident de dimensionnement (AD) ou d’une condition additionnelle de dimensionnement (CAD) pendant la phase d’exploitation du cycle de vie de l’installation.

Notes :

Cette norme s’applique uniquement aux fonctions des systèmes de la centrale, y compris les systèmes de sûreté et les systèmes de commande des procédés, associées à la surveillance en cas d’accident; les autres fonctions de surveillance ne font pas partie du domaine d’application de cette norme.

Il peut y avoir des différences entre les exigences pour un AD et celles pour une CAD. De telles différences, lorsqu’elles existent, sont explicitement mentionnées.

Les exigences et les lignes directrices relatives aux CAD (un sous-ensemble des accidents de dimensionnement [AD]) sont traitées dans CSA N290.16.

La phase d’exploitation du cycle de vie de l’installation comprendrait la période pendant laquelle le réacteur est capable de fonctionner, généralement de la fin de la mise en service lorsque le combustible est chargé à la fin de l’exploitation lorsque le combustible est déchargé avant le déclassement.

 

1.2  Centrales existantes et nouvelles centrales

Cette norme s’applique aux centrales existantes et aux nouvelles centrales.

Notes :

Les exigences peuvent différer pour les nouvelles centrales et pour les centrales existantes. De telles différences, lorsqu’elles existent, sont explicitement mentionnées.

Dans le cas des centrales existantes, la demande devrait, dans la mesure du possible, porter sur les informations contenues dans la présente norme. Toute autre approche sélectionnée ou mesure d’atténuation appliquée devrait être indiquée.

Cette norme peut orienter les installations nucléaires autres que les centrales nucléaires, selon une méthode graduelle.

1.3 

ApplicabilitéCette norme s’applique aux composants et aux systèmes qui, en cas d’accident, permettent au personnel de la centrale nucléaire de :

a) surveiller et afficher les fonctions de sûreté de la centrale pour diagnostiquer qu’un accident, y compris un accident grave, se produit ou s’est produit;

Note : La surveillance des fonctions de sûreté de la centrale a pour but de guider l’opérateur dans le choix des mesures d’intervention requises à la suite de l’accident.

 

b) surveiller et afficher l’état de la centrale aux fins de gestion des accidents pour traiter en continu l’état des fonctions de sûreté; et

Note : La gestion des accidents fait référence aux mesures particulières prises dans une centrale nucléaire pendant l’évolution d’un accident de manière à en empêcher l’intensification, atténuer les conséquences et atteindre un état stable contrôlé à long terme. La responsabilité des mesures de gestion des accidents incombe à l’exploitant. Voir le document REGDOC-2.3.2 de la CCSN pour plus de précisions à ce sujet.

 

c) surveiller et afficher les paramètres pour le déclenchement des mesures de gestion des urgences sur le site et hors site pour confirmer l’efficacité des mesures de gestion des accidents.

Notes :

Dans ce contexte, la gestion des urgences fait référence à l’intervention globale coordonnée pour atténuer une urgence nucléaire et reprendre les activités à la suite d’une telle urgence. La gestion des urgences ne porte pas sur les mesures particulières à prendre dans une centrale nucléaire pour gérer les accidents (c.-à-d., pour la gestion des accidents telle que décrite à l’alinéa précédent). Les mesures de gestion des urgences peuvent être la responsabilité de l’exploitant ou d’autres autorités compétentes (p. ex., les organismes de gestion des urgences de l’exploitant, les organismes gouvernementaux, des travailleurs d’urgence). Voir la CSA N1600 pour les lignes directrices sur la catégorisation des urgences nucléaires et les annonces en cas d’urgence nucléaire.

Si le fondement de la planification d’urgence, telle que définie dans CSA N1600, ne nécessite pas de mesures de gestion des urgences hors site, toute fonction associée à la surveillance des paramètres hors site peut être exclue lorsque cela est justifié.
