1        Scope

1.1         

This Standard provides requirements for the materials used in concrete containment structures.

1.2        

This Standard is applicable to existing and new nuclear power plants. It is not the intent that the requirements of this Standard be applied retroactively to existing nuclear power plants, unless as agreed to by the AHJ.

1.3        

This Standard is used in concert with the following standards, as applicable:

a) CSA N287.1, which outlines general requirements for concrete containment structures for nuclear power plants; and

b) CSA N287.8, which outlines aging management requirements for concrete containment structures for nuclear power plants.

Note: In Canada, CNSC REGDOC 2.6.3 provides the regulatory requirements for managing the aging of structures, systems and components of a nuclear power plant (NPP).

1.4        

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.

1.5        

In this Standard, “shall be considered” or “shall consider” means that the user evaluates the impact and documents any decisions.

Note: Examples can include no action, operating procedures, design features.

1.2

This standard applies to newly produced industrial gas-fired natural draft heaters (see clause 3, Definitions) utilizing new and unused parts and materials intended for indoor and outdoor installation in non-hazardous locations in oil and gas process applications with a maximum input rating up to 12,500,000 Btu/h (3,663,389 W).

1.3

A heater may be factory-built as a single heater or as a packaged system (see clause 3, Definitions) intended to be disassembled for shipping and reassembled for installation.

1.4

The term "heater” when used herein applies to gas-fired industrial natural draft heaters. Examples could include but are not limited to a fire tube heater, process heater, line heater, or tank heater (see clause 3, Definitions).

1.5

The term “gas” when used herein applies equally to the following gases:

1.7

The values given in yard/pound units are the standard. The values given in parentheses are for information only. 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. All references to psi (kPa) throughout this Standard are to be considered "gauge" pressures unless otherwise specified.

0.1            Facilities

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.
