43、on, fabrication, and installation requirements forconcrete containment structures for CANDU nuclear power plantsOctober 2009 ixPrefaceThis is the fourth edition of CSA N287.4, Construction, fabrication, and installation requirements for concrete containment structures for CANDU nuclear power plants.
44、 It supersedes the previous editions published in 1992, 1983, and 1977.This Standard provides requirements for construction, fabrication, and installation for concrete containment structures. Together with the other CSA N287 Standards, it provides the requirements for concrete containment structures
45、 for CANDUnuclear power plants. These Standards were initiated in response to the recognition by the utilities and industries concerned with nuclear power plant structures in Canada of a need for consistent standards for the design, construction, and testing of concrete containment structures for CA
46、NDU nuclear power plants.Note: CANDU (CANada Deuterium Uranium) is a registered trademark of Atomic Energy of Canada Limited (AECL).Users of this Standard are reminded that the design, manufacture, construction, commissioning, operation, and decommissioning of nuclear facilities in Canada are subjec
47、t to the provisions of the Nuclear Safety and Control Act and its Regulations. Requirements additional to those specified in this Standard could be imposed by the Canadian Nuclear Safety Commission.This Standard was prepared by the Subcommittee on Construction, Fabrication, and Installation Requirem
48、ents for Concrete Containment Structures for CANDU Nuclear Power Plants, under the jurisdiction of the Technical Committee on Concrete Containment and Safety-Related Structures and the Strategic Steering Committee on Nuclear Standards, and has been formally approved by the Technical Committee.Octobe

Consensus implies much more than a simple majority,
