1.1 Facilities

1.1.1 Types of facilities

This Guideline addresses the I&E monitoring and assessment programs for nuclear facilities.

Notes:

1) In this Guideline, any type of nuclear facility is included in the term “nuclear facilities.”

2) I&E monitoring and assessment programs might not be appropriate for all nuclear facilities. This Guideline is intended primarily for high-water users and facilities where species at risk might be present, and the applicability of this Guideline would be determined by the user in conjunction with the authority having jurisdiction (AHJ).

3) Nuclear facilities include cooling and process types of facilities. The technique to be used for I&E can vary among these types of facilities. Figure 1 illustrates how a potential user might determine the applicability of this Guideline, depending on whether the facility has a cooling water intake structure (CWIS) or process water intake structure (PWIS).

4) AHJ direction on application for I&E can vary and might depend on the facility’s type of cooling, the presence of species at risk, and the type of mitigation in place at the screen.

5) Drinking water intake structures are commonly beyond the scope of this Guideline.

6) This Guideline might not apply to temporary intake structures; applicability can be determined with the AHJ.

7) For facilities with extraction rates less than 125 L/s, I&E monitoring might not be needed if mitigation measures consistent with the DFO’s Interim code of practice: end-of-pipe fish protection screens for small water intakes in freshwater are used. Further detail is provided in Figure 1.

 

1.1.2 Facility lifecycle

1.1.2.1 Operations phase

The I&E program is intended to be used during the operations phase and can function in other phases, as applicable.

1.1.2.2 Operational phases

Consideration of this Guideline, or components of this Guideline as applicable, can be included during the following phases of a facility lifecycle:

a) construction;

b) commissioning and other pre-operational tasks;

c) operations (including outages and refurbishment); and

d) decommissioning (including storage with surveillance).

Notes:

1) The details of an I&E monitoring program might change over the lifecycle of the facility.

2) Because there are likely no fish impingement or entrainment issues during post-decommissioning, this Guideline is not applicable during post-decommissioning.

1.2 Operating conditions

This Guideline is applicable during normal operations of a nuclear facility.

Notes:

1) This Guideline is not applicable during accident or emergency scenarios, although some parts of this Guideline might be useful. In these cases, the user determines the applicability of the guidance.

2) Documentation of changes in operational conditions (e.g., outage or refurbishment periods when there is substantially less or no water intake) will help explain changes in I&E observed.

1.3 Methods of data analysis

This Guideline provides guidance on methods of collecting and analyzing data relevant to I&E of fish. It does not provide guidance on the acceptability of the effects or on the mitigation of the effects.

Notes:

1) Establishing how the data could be used in assessing significance of effects and what mitigation options might be available or already in place will improve the usefulness of the output of the I&E program.

2) The user of this Guideline is responsible for determining what data analysis and interpretation is necessary to confirm compliance with all statutes, regulations, licences, or permits that govern the operation of the nuclear facility.

1.4 Terminology

In this Guideline, “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 this Guideline. This document provides guidance only and there are no requirements indicated within the document.

1.1 Installations

1.1.1 Types d’installations

Ce document traite des programmes de surveillance et d’évaluation de C&E pour les installations nucléaires.

Notes :

1) Dans ce document, le terme « installation nucléaire » désigne tout type d’installation nucléaire.

2) Les programmes de surveillance et d’évaluation de C&E pourraient ne pas convenir aux installations nucléaires. Ce document est principalement destiné aux grands utilisateurs d’eau et aux installations où pourraient se trouver des espèces en péril, et l’applicabilité de ces directives serait déterminée par l’utilisateur en accord avec l’autorité compétente (AC).

3) Les installations nucléaires incluent les installations de traitement et de refroidissement. La technique préconisée pour le C&E pourrait varier entre ces différents types d’installation. La figure 1 illustre comment un utilisateur éventuel pourrait déterminer l’applicabilité de ces directives, selon que l’installation dispose d’une prise d’eau de refroidissement (PER) ou d’une prise d’eau de traitement (PET).

4) Les consignes de l’autorité compétente quant à l’application pour le C&E pourraient varier et dépendre du type de système de refroidissement en usage dans l’installation, de la présence d’espèces en péril, et du type de mesures d’atténuation en place là où se trouve le grillage.

5) Les prises d’eau potable sont habituellement hors du domaine d’application des présentes directives.

6) Ces directives pourraient ne pas s’appliquer aux prises d’eau temporaires; son applicabilité dans ces situations pourrait être déterminée en accord avec l’autorité compétente.

7) Dans les installations présentant des taux d’extraction inférieurs à 125 L/s, la surveillance de C&E pourrait ne pas être nécessaire si des mesures d’atténuation conformes au Code de pratique provisoire – Grillages à poissons à l’entrée des petites prises d’eau douce de Pêches et Océans Canada sont employées. Plus de détails sont présentés à la figure 1.

 

1.1.2 Cycle de vie d’une installation

1.1.2.1 Phase d’exploitation

Le programme de C&E est destiné à être utilisé lors de la phase  d’exploitation et pourrait aussi l’être pendant d’autres phases, au besoin.

La prise en compte de cette ligne directrice, ou de certains de ses éléments selon le besoin, pourrait être incluse dans les phases suivantes du cycle de vie d’une installation :

a) construction;

b) mise en service et autres tâches pré-opérationnelles;

c) exploitation (y compris les arrêts et le réfection); et

d) déclassement (y compris le stockage surveillé).

Notes :

1) Les détails d’un programme de surveillance de C&E pourraient changer au cours du cycle de vie de l’installation.

2) Étant donné le faible risque de captage ou d’entraînement des poissons pendant la phase post-déclassement, la présente ligne directrice ne s’applique pas à cette phase.

1.2 Conditions d’exploitation

Cette ligne directrice est applicables durant l’exploitation normale d’une installation nucléaire.

Notes :

1) Cette ligne directrice n’est pas applicable en cas d’accident ou d’urgence, bien que certaines sections pourraient s’avérer utiles. Dans ces situations, il revient à l’utilisateur de déterminer l’applicabilité des directives.

2) La documentation des changements aux conditions d’exploitation (p. ex., arrêts ou périodes de réfection durant lesquelles la prise d’eau est interrompue ou grandement diminuée) aidera à éclairer les variations de C&E observées.

1.3 Méthodes d’analyse des données

Cette ligne directrice fournit des méthodes de collecte et d’analyse des données relatives au C&E des poissons. Elle ne fournit pas de directives sur l’acceptabilité des effets ou sur l’atténuation des effets.

Notes :

1) Déterminer la manière dont les données pourraient être utilisées pour évaluer l’importance des effets et les solutions d’atténuation éventuellement disponibles ou déjà en place augmentera l’utilité des résultats du programme de C&E.

2) Il incombe à l’utilisateur de cette ligne directrice de déterminer le type d’analyse et d’interprétation des données nécessaires pour se conformer aux dispositions de l’ensemble des lois, licences et permis régissant l’exploitation de l’installation nucléaire.

1.4 Terminologie

Dans cette ligne directrice, « 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. Ce document fournit uniquement des lignes directrices et ne formule aucune exigence.
