This is the first edition of CSA Standard CAN/CSA—N293, Fire Protection for CANDU Nuclear Power Plants.
This Standard was prepared in recognition of the need for a Standard for fire protection in nuclear power plants of the CANDU design. In this respect, this Standard uses nuclear terminology consistent with CANDU safety philosophy and addresses unique CANDU power plant design features. It reflects CANDU operating experience and is consistent with industrial standards and practices for fire protection and with life safety requirements imposed by Canadian authorities for protection of plant personnel.
The purpose of this Standard is to provide a set of requirements that can be used in a programmatic manner for the design, construction, operation, and decommissioning of a CANDU nuclear power plant and that will ensure adequate fire protection.
In the preparation of this Standard, extensive reference has been made to existing codes and Standards. The latest revisions of the reference publications available at the time of printing are listed in Clause 2. Future revisions of these referenced documents will be reviewed for applicability with each revision of this Standard. While Certain Standards are being used at various regulatory levels, it should be noted that this publication recognizes only those Standards that are used at the national level. It is understood that such national Standards may be augmented or superseded by Standards issued by provincial or local authorities.
This Standard was prepared by the Technical Committee on Fire Protection for CANDU Nuclear Power Plants and the 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.
This Standard covers requirements and guidelines for protection against fires for CANDU nuclear power plants. It. applies to the design, construction, commissioning, operation, and decommissioning of the plant.
