This is the fourth edition of CSA N287.6, Pre-operational proof and leakage rate testing requirements for concrete containment structures for nuclear power plants. It supersedes the previous editions, published in 1994, 1980, and 1978 under the title Pre-Operational Proof and Leakage Rate 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 requirements for pre-operational proof and leakage rate testing of concrete containment structures of a containment system that are designated as class containment components.
Note: Other components and appurtenances of the containment system may be tested coincident with the tests specified in this Standard provided that the intent of this Standard is observed and the requirements of CSA N285.0 are considered.
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.
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.
