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      Scope

1.1     

This Standard provides requirements for in‑service examinations of concrete containment structure and integrated leakage rate testing (ILRT) of the containment boundary.

1.2   

In-service examination of containment system components designed in accordance with the CSA N285 suite of Standards are beyond the scope of this Standard.

Note: CSA N285.5 provides requirements for periodic inspection of CANDU nuclear power plant containment components that are made of metallic or plastic materials and that form the containment boundary or are part of fluid handling systems that penetrate the containment structure. 

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).

CSA 3.21-1

1. Scope

1.1

CSA 3.21, Standard for Industrial Gas-Fired Natural Draft Heaters for Installation in Hazardous and Non-Hazardous Locations in Oil and Gas Process Applications, is arranged in two parts:

(a)CSA3.21-1 covers Industrial Gas-Fired Natural Draft Heaters for Installation in Non-Hazardous Locations in Oil and Gas Process Applications.

(b)CSA3.21-2 covers Industrial Gas-Fired Natural Draft Heaters for Installation in Hazardous Locations in Oil and Gas Process Applications.

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:

Natural gas; and Propane.

Heaters may be convertible for use with natural gas and propane gas, when provision is made for the conversion from one gas to the other. 

1.6

This standard does not apply to:

a)Heaters whose primary use is to provide direct comfort space heating,

b)Heaters used or installed in a space where people may sleep or may be located in or near an area that has sleep accommodation; or

c)Residential or commercial equipment.

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.

1.8

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.
