CAN/CSA-N285.0-95 (R2005)
1. Scope
1.1
This Standard specifies the general requirements for the design, fabrication,
and installation of pressure-retaining systems, components, and their supports
in CANDU nuclear power plants. It also includes requirements that are specific
to Class 1, 2, and 3 systems and components.
1.2
This Standard, to the extent specified herein, applies to all
pressure-retaining systems and components and their supports in a nuclear power
plant and takes precedence over other standards.
1.3
When this Standard is adopted for facilities other than CANDU nuclear power
plants, the classification clauses should not be considered to be relevant
unless
(a) the facility has a defined exclusion zone;
(b) access to the facility is controlled, permitting entry only by authorized
personnel; and
(c) the reactor is situated in a containment that is capable of limiting
releases to the environment in the event of a failure of a pressure-retaining
component.
1.4
This Standard does not apply to containment system components classified as
Class Containment that comply with the requirements of the CSA N287 Series of
Standards.
Notes:
(1) This Standard includes requirements of a regulatory nature that are
commonly applied. These nontechnical requirements are derived from Canadian
legislation. The Atomic Energy Control Act and Regulations, as well as the
appropriate acts and regulations of each province of Canada covering boilers
and pressure vessels, determine the scope of a jurisdiction and the extent of
the requirements for design registration and inspection of systems and
components of a nuclear power plant in that province.
(2) Imperial equivalent values to the SI units are shown in parentheses for
information only.
