This is the third edition of CSA N287.5, Examination and testing requirements for concrete containment structures for nuclear power plants. It supersedes the previous editions, published in 1993 and 1981 under the title Examination and Testing Requirements for Concrete Containment Structures for CANDU Nuclear Power Plants. The title has been changed to reflect a scope change, from addressing CANDU® reactors to including any nuclear power plant.
This Standard specifies examination and testing requirements that apply to the work of any organization participating in the construction, fabrication, or installation of parts or components of concrete containment structures for nuclear power plants that are designated as class containment.
This Standard specifies personnel qualification requirements for work pertaining to the examination and testing of concrete containment structures for nuclear power plants in accordance with this Standard.
This Standard may be applied, as appropriate, to nuclear facilities under the jurisdiction of the Government of Canada's Nuclear Safety and Control Act.
In CSA standards, 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.
