Type of consequence assessments

This Standard proposes methods for modelling the consequences of accidents at nuclear reactors for safety assessment and real-time emergency response.

1 Domaine d’application

1.1 Types d’évaluation des conséquences

Cette norme propose des méthodes pour la modélisation des conséquences des accidents mettant en cause des réacteurs nucléaires pour l’évaluation de la sûreté et les interventions en temps réel en cas d’urgence.

Notes :

a1)  Les modèles utilisés pour évaluer les conséquences d’un accident postulé aux fins d’évaluation de la sûreté sont très semblables à ceux utilisés pour les conséquences d’un accident nucléaire en temps réel aux fins d’intervention en cas d’urgence, y compris le calcul de la dispersion et des concentrations atmosphériques. Toutefois, les deux types de modèles ne traitent pas les termes source et les paramètres ultimes de la même manière.

b2)  L’évaluation de la sûreté est une activité prospective qui comprend :

i) les calculs déterministes et probabilistes effectués aux fins de l’octroi de la licenceaux fins de satisfiaire aux exigences de l’autorité compétente (AC) ;

ii) l’évaluation probabiliste du risque dans le cadre d’analyses coûts-bénéfices ; et

iii) les calculs déterministe et probabilistes effectués aux fins de la planification des mesures d’urgence.

c3)  L’évaluation des conséquences de l’intervention en cas d’urgence est effectuée pendant une vraie urgence pour confirmer la protection du public et de l’environnement. L’évaluation des conséquences de l’intervention en cas d’urgence est effectuée pour les accidents postulés pour confirmer les activités de préparation comme l’implantation de centres d’accueil des évacués et la formation des intervenants d’urgence.

Tous les états d’une centrale en cas d’accident nucléaire sont couverts par le champ d’application de cette norme (voir REGDOC 2.5.2).

Scope

1.1 Reactors and other potential sources

This Standard provides the requirements and guidance for the preparation and maintenance of a PSA at a water-cooled NPP. The radiation sources of concern include both

a) water-cooled power reactors; and

b) other potential sources of radioactive releases to the environment.

Notes:

This Standard may be used to provide guidance for nuclear facilities other than NPPs.

“Other potential sources” include, for example, wet storage bays and dry used fuel storage facilities.

Systems that only contain radiation during post-accident conditions e.g. ECI recovery, are not considered in the identification of radiation sources. The source of radiation of those systems is the reactor, which is considered already as a source

1.2 New and existing reactors

This Standard applies to both new and existing water-cooled NPPs.

Notes:

1) “Existing NPPs” refers to NPPs initially licensed before 2017.

2) “New NPPs” refers to NPPs initially licensed after 2016.

3) The requirements for a new NPP might be different than the requirements for an existing NPP. This Standard notes where the requirements might be different.

1.3 Single and multi-reactor facilities

This Standard applies to NPPs with one or more water-cooled power reactors.

Notes:

1) The requirements for a single-reactor NPP might be different than the requirements for a multi-reactor NPP. This Standard notes where the requirements might be different.

2) Provisions related to the risk aggregation and whole-site PSA is provided in Clause 13, Clause 14 and Annex I of this standard.

1.4 Level 1 PSA and Level 2 PSA

This Standard addresses both Level 1 PSA and Level 2 PSA.

1.5 Whole-site PSA

This Standard applies to both specific PSAs and whole-site PSAs.

Notes:

A specific PSA might assess only a single hazard for a single source at a NPP.  A whole-site PSA assesses all sources and all hazards.

Some parts of this Standard apply only to specific PSAs.  For example, Annexes C to H apply only to specific hazards for power reactors.  This Standard notes where requirements apply only to specific PSAs.

1.6 Malevolent acts

This Standard does not address and does not apply to malevolent acts.

Note: In Canada, malevolent acts are addressed separately under the CNSC Nuclear Security Regulations.

1.7 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 Domaine d’application

1.1 Réacteurs et autres sources possibles

Cette norme énonce les exigences visant la préparation et la tenue à jour de l’étude probabiliste de sûreté effectuée pour les centrales nucléaires dotées d’un réacteur refroidi à l’eau. Les sources de rayonnement préoccupantes sont

a) les réacteurs de puissance refroidis à l’eau ; et

b) les autres sources possibles de rejets radioactifs dans l’environnement.

Notes :

1) Cette norme peut être utilisée comme guide pour les installations nucléaires autres que des centrales nucléaires.

2) Les «autres sources possibles» incluent, par exemple, les piscines de stockage et les installations de stockage à sec du combustible irradié.

3) Systems that only contain radiation during post-accident conditions e.g. ECI recovery, are not considered in the
identification of radiation sources. The source of radiation of those systems is the reactor, which is considered already as a source.

This Standard applies to cleaning and disinfection of HCFs providing health care services including, but not limited to, inpatient services or outpatient services. See definition of HCF in Clause 3.

1 Scope and object

This clause of Part 1 is applicable except as follows:

1.1.1 Equipment included in scope

Replacement:

Replace the second paragraph by the following:

This part of IEC 61010 specifies safety requirements for electrical equipment and its accessories within the categories a) through c), wherever it is intended to be used, whenever that equipment incorporates one or more of the following characteristics:

• A REFRIGERATING SYSTEM that is acted on or impacted by an integral heating function such that the combined heating and REFRIGERATING SYSTEM generates additional and/or more severe HAZARDS than those for the two systems if treated separately.

• The materials being treated in the intended application introduce significant heat into the REFRIGERATING SYSTEM, so that the REFRIGERATING SYSTEM in the application yields additional and/or more severe HAZARDS than those for the REFRIGERATING SYSTEM if operated at the maximum RATED ambient temperature alone.

• An irradiation function for the materials being treated presenting additional HAZARDS.

• A function to expose the materials being treated to excessive humidity, carbon dioxide, salt mist, or other substances which can result in additional HAZARDS.

• A function of MECHANICAL MOVEMENT presenting additional HAZARDS.

• Provision for an OPERATOR to walk in to the operating area to load or unload the materials being treated.

Addition:

Add the following text after the last paragraph:

NOTE 101 Examples of such equipment include environmental testing and plant growth TEST CHAMBERS, refrigerating CIRCULATORS which incorporate heating, and recirculating coolers for extracting heat. It is possible that all or part of the equipment falls within the scope of one or more other Part 2 standards of IEC 61010 as well as within the scope of this standard. In that case, the requirements of those other Part 2 standards also apply. This document is intended for application when one or more of the additional HAZARDS described in the above dashed listed items are introduced. However, when the equipment incorporates only a REFRIGERATING SYSTEM or only a heating function or a combination of the two without introducing the additional HAZARDS described in the above list, then IEC 61010-2-011 or IEC 61010-2-010 or both, as appropriate, apply instead of this Part 2-012. See further information in the flow chart (Figure 102) for selection process and guidance in the Introduction.

(c)    performing seismic analyses, including the effects of the soil-structure-interaction.
