Unless otherwise specified, all references to pressure throughout this Code are to be considered gauge pressures.

1.4 Terminology

In this Code, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Code; “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 Code.

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 Units of measurement

The values given in SI units are the units of record for the purposes of this Code. The values given in parentheses are for information and comparison only.

Notes:

1)   IEEE/ASTM SI 10 or ISO 80000-1 can be used as a guide when converting U.S. customary units to SI units.

2)   Where the abbreviation “gal” is used in this Code, it indicates a U.S. gallon equivalent to 3.785 L water capacity.

3)   This Code was developed originally using the U.S. customary system of measurement and subsequently converted to SI units having three significant digits. Every attempt has been made to provide accurate conversion values; however, when designing systems using these values, engineering judgment should be applied.

1.1  Purpose

This Standard establishes requirements for pressure-retaining systems, components, and their supports over the service life of a CANDU NPP. The requirements of this Standard address

construction activities; and

in-service inspection, modification, repair, and replacement activities.

1.2  Applicability to pressure-retaining systems

This Standard applies to all pressure-retaining systems, including their components and supports, in a CANDU NPP.

1.3  Applicability to containment components

This Standard applies to containment components, but does not apply to containment structures which are covered in the CSA N287 Series of Standards.

1.4  Exclusion of portable assemblies

This Standard does not apply to portable assemblies of pressurized items that are temporarily connected to a system or component to enable testing, venting, draining, calibration, or other maintenance activities, provided that they

do not reduce the ability of a system to perform its design safety function;

are under surveillance when connected and are removed upon completion of their function; and

are constructed to Standards deemed by the licensee to be suitable for the application.

Note: Safety analysis, environmental qualification programs, or seismic qualification may be used to satisfy the conditions in this Clause.

1.5  Exclusion of sensing elements

This standard does not apply to sensing elements of instruments, except when the sensing element is included in the design of a component pressure boundary.

1.6  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 (nonmandatory) to define their application.

1.7  Units of measurement

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only. The units in this Standard may be converted in accordance with the ASME BPVC, Section III, NCA-1150.
