Preface
This is the third edition of CSA Standard N287.2-M (now designated CAN3—N287.2), Material Requirements for Concrete Containment Structures for CANDU Nuclear Power Plants. It supersedes the second edition of N287.2, published in 1977, and the preliminary edition published in 1976, in which Imperial Units of measurement were used. All measurement-sensitive requirements have been revised and are now expressed in SI (metric) units of measurement.
Development of this Standard began in 1973 under the sponsorship of the Canadian Nuclear Association's Codes, Standards and Practices Committee. In 1974, the decision was made to promulgate this document as a CSA Standard.
The purpose of this Standard is to provide requirements that ensure the materials used in concrete containment structures will meet a quality and standard commensurate with the safety principles necessary to comply with the Canadian nuclear safety philosophy.
This Standard together with the Standards listed below and such additional ones as may be required from time to time will comprise the Series of Standards that will provide the requirements for concrete containment structures for CANDU nuclear power plants:
CSA Standards
CAN3—N287.1,
General Requirements;
CAN3-N287.3,
Design Requirements;
CAN3-N287.4,
Construction, Fabrication and Installation Requirements;
CAN3-N287.5,
Testing and Examination Requirements;
CAN3-N287.6,
Pre-operational Proof and Leakage Rate Testing Requirements; and
CAN3—N287.7,
In—Service Examination and Testing Requirements.
Standards in this Series were initiated in response to a recognition by the utilities and industries concerned with nuclear structures in Canada, of a need for the documentation of Standards applicable to the design, construction, and testing of concrete containment structures incorporated as components of a CANDU nuclear power plant.
In the preparation of this and the above Standards, it was the decision of the Committee to make use of existing Standards, Codes and other reference material wherever possible.
This Standard was prepared by the Technical Committee on Concrete Containment Structures for Nuclear Power Plants under the jurisdiction of the Standards Steering Committee on Nuclear Standards and was formally approved by these Committees. It has been approved as a National Standard of Canada by the Standards Council of Canada.
Scope
1.1
This. Standard covers materials used in concrete containment structures of a containment system, designated as Class Containment components and parts.
