0.1.1            Types of facilities

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

Notes:

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

2.  Not all Class I nuclear facilities require I&E monitoring and assessment programs. 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.  Class I 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 are employed that are consistent with the DFO Freshwater Intake End-of-Pipe Fish Screen Guideline. Further detail is provided in Figure 1.

1 Scope

1.1

This Standard applies to fuel gas piping systems using corrugated stainless steel tubing (CSST), intended for installation in residential, commercial or industrial buildings, and including the following components as a minimum:

a)   Corrugated stainless steel tubing (CSST);

b)   Fittings for connection to the CSST; and

c)   Striker plates (see Clause 3, Definitions) to protect the installed CSST from puncture threats.

Other components of piping systems covered by this Standard include gas manifolds, gas pressure regulators, manual gas valves, quick-disconnect devices and gas convenience outlets (see Clauses 4.3, Gas pressure regulators, 4.4, Manually operated gas valves and 4.5, Quick-disconnect devices and gas convenience outlets). If such additional components are required to complete the piping system installation, they are either provided as part of the piping system or specified in the manufacturer’s installation instructions (see Clause 4.7-m).

1.2

This Standard also applies to corrugated stainless steel piping systems in which portions of the piping are exposed to the outdoors as required to make connections to outdoor gas meters or to outdoor gas appliances, which are attached to, mounted on or located in close proximity to the building structure.

1.3

This Standard does not apply to CSST, whether coated or uncoated, intended for direct burial underground. Tubing is installed underground only when encased inside either an approved conduit or as part of an approved engineered system and in accordance with local codes and the manufacturer's instructions.

1.4

This Standard includes criteria to establish the suitability of concealed mechanical tube fittings for use with concealed gas piping (see Clause 3, Definitions).

1.5

This Standard also applies to corrugated stainless steel piping systems that are used in conjunction with other approved fuel gas piping materials.

1.6

This Standard applies to piping systems rated at either 5 psi (34.5 kPa) and intended for exposure to maximum actual operating pressures (see Clause 3, Definitions) not exceeding 6.5 psi (44.8 kPa), or rated at 25 psi (172.5 kPa) and intended for exposure to maximum actual operating pressures not exceeding 30 psi (207 kPa). The manufacturer has the option to certify its system to either pressure rating.

1.7

This Standard applies to piping systems not exceeding a size of 2 inches (50.8 mm), based on the nominal inside diameter of the tubing.

1.8

This Standard does not apply to gas connectors for appliances. These connectors are covered by the Standard for Metal Connectors for Gas Appliances, and the Standard for Connectors for Movable Gas Appliances, ANSI Z21.24 • CSA 6.10 and Z21.69 • CSA 6.16.

1.9

This Standard does not apply to piping systems intended for use with propane in the liquid state.

1.10

All references to psi throughout this Standard are to be considered gauge pressure unless otherwise specified.

1.11

If a value for measurement as given in this Standard is followed by an equivalent value in other units, the first stated value is to be regarded as the specification.

1.12

Clause 7 contains provisions that are unique to Canada.

1.13

Clause 2 contains a list of standards specifically referenced in this Standard.

1.14

In this Standard, “shall” Is used to express a requirement, i.e. a provision that the use shall 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   Scope

1.1

This Standard covers the qualification, application, inspection, testing, handling, and storage of materials required for coatings applied externally to steel piping in the field or a shop. Coated piping addressed by this Standard is intended primarily for buried or submerged service in oil or gas pipeline systems.

1.2

This Standard covers the following coating systems:

(a)  System FC1: liquid-applied epoxy or fusion bond epoxy (FBE) with a glass transition temperature of up to 115 °C;

(b)  System FC2: liquid-applied epoxy or FBE with a glass transition temperature of 115 °C or greater;

(c)  System FC3: liquid-applied epoxy or FBE intended for abrasion service;

(d)  System FC4: adhesive and a polymeric backing (e.g., tape, heat shrinkable sleeve);

(e)  System FC5: epoxy primer, adhesive, and a polymeric backing (e.g., tape, heat shrinkable sleeve);

(f)  System FC6: anti-corrosion coating, if applicable [see Items (a), (b), (d) and (e)], polyurethane foam insulation, and a polymeric backing with or without adhesive (e.g., tape, heat shrinkable sleeve); and

(g) System FC7: fibre-reinforced petrolatum, paraffin-filled, or visco-elastic systems.

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.
