1.1
This Standard specifies the framework and calculation models for “essential energy benchmarking” of data centres as a new form of ideal-state benchmarking for energy performance. It provides the specifications necessary to benchmark the energy efficiency performance of a data centre by using a dimensionless indicator called the benchmark energy factor (BEF).

This Standard is a reference document for the application of essential energy benchmarking to data centres. The essential energy model is based on best available technology (BAT) and fundamental thermal, mechanical, electrical, and/or work-load components. The BAT is determined independent of cost and, in most cases, independent of the equipment that is currently in use within a data centre that is using this Standard. Exceptions are provided for when a data centre is using IT equipment that is not covered by the essential energy models.

This Standard applies to the use of electrical energy for the data centre.

Data centres that are included within the scope of this Standard include data centres with a minimum IT load of 100 kW that are typically used in enterprises, government, institutional (hospital and University), and other facilities where the organization has influence over the equipment and a vested interest in the energy consumption of the data centre. This may include third-party managed data centres when the above conditions are met.

1.2
Specifically excluded from the scope of this Standard are the following:

  a) colo data centres – given that the data centre operator does not usually have control over the IT equipment or the software environment;

  b) telco data centres – given that the majority of equipment is specialized hardware equipment that are not currently supported by the essential energy models; and

  c) data centres that have the cost of electricity embedded in the rent – given that there is no direct financial benefit to improving the energy efficiency of the data centre.

1.3
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.

1.1
This Standard covers the design, qualification, installation, commissioning, operation, maintenance, testing, inspection, and documentation requirements for systems providing heat removal from the reactor core to the ultimate heat sink(s) for water-cooled nuclear power plants during outages.

This standard does not cover requirements for design extension conditions (DEC). Requirements and principles for maintaining fuel cooling for outages during DECs, including requirements for emergency cooling water and power supplies, are covered in CSA N290.16.

1.2
This Standard covers only fuel cooling within the reactor core and does not cover spent fuel pool cooling, off-reactor fuelling operations, or the completely defueled core state.

1.3
The term “outage” refers to the following reactor states:

a)  a shutdown state where subcriticality is assured by physical means; or

Note: For CANDU reactors, this refers to a guaranteed shutdown state.

b) critical or sub-critical at any power where the normal (at high power) heat sinks are not the primary heat sinks.

Note: Examples of high power heat sinks include steaming of boilers to turbine or condensers.

1.4
For the purposes of this Standard, the outage commences when the normal (at high power) heat sinks are no longer the primary heat sinks.

The outage is considered to be terminated when the normal (at high power) heat sinks are re-established as part of the plan to proceed to sustained high power operation.

1.5
This Standard covers all systems that contribute to the transfer of heat by

a) conveying heat to the ultimate heat sink;
b) providing power or compressed air;
c) providing inventory makeup to heat sink systems; or
d) monitoring and control.

Note: The combination of systems or portions of systems that contribute to these functions are referred to in this Standard as “heat sinks”.

1.6
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.

1.1
Cette norme s’applique à la conception, à la qualification, à l’installation, à la mise en service, à l’exploitation, à l’entretien, à la mise à l’essai, à l’inspection et à la documentation des systèmes qui assurent l’évacuation de la chaleur du cœur du réacteur vers la ou les sources froides ultimes pour les centrales nucléaires refroidies à l’eau pendant les arrêts.

Cette norme ne traite pas des exigences relatives aux conditions additionnelles de dimensionnement (CAD). Les exigences et les principes relatifs au maintien du refroidissement du combustible pendant les arrêts en CAD, notamment les exigences relatives aux systèmes d’approvisionnement d’urgence en eau de refroidissement et d’alimentation électrique sont énoncées dans CSA N290.16.

1.2
Cette norme s’applique uniquement au refroidissement du combustible dans le cœur du réacteur ; elle ne s’applique pas au refroidissement du combustible épuisé, au ravitaillement à l’extérieur du réacteur ni au réacteur dont on a retiré le combustible.

1.3
Le mot «arrêt» s’applique aux conditions suivantes du réacteur :

a) un état d’arrêt sous-critique assuré par des moyens physiques ; ou

Note : Dans le cas des réacteurs CANDU il s’agit d’un état d’arrêt garanti.

b) un état d’arrêt critique ou sous-critique peu importe la puissance lorsque les sources froides normales (à puissance élevée) ne sont pas la source froide primaire.

Note : L’injection de vapeur dans les turbines ou les condenseurs sont des exemples de sources froides à puissance élevée.

1.4
Dans le contexte de cette norme, l’arrêt commence au moment où les sources froides normales à puissance élevée ne sont plus considérées comme la source froide primaire.

On considère que l’arrêt est terminé lorsque les sources froides normales à puissance élevée recommencent à faire partie de l’exploitation à puissance élevée.

1.5
Cette norme s’applique à tous les systèmes qui contribuent au transfert de la chaleur

a) par le transport de la chaleur vers la source froide ultime ;
b) en fournissant de l’énergie ou de l’air comprimé ;
c) en maintenant l’inventaire des sources froides ; ou
d) par la surveillance et le contrôle.

Note : L’expression «sources froides» utilisées dans cette norme s’applique à la combinaison des systèmes ou des portions des systèmes qui contribuent à ces fonctions.

1.6
Dans cette norme, le terme «doit» indique une exigence, c’est-à-dire 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 qui ne font pas proprement partie de la norme.
