Fire Protection for Candu Nuclear Power Plants CSA N293-07 “Its Impact on Existing, Modified, Refurbished, and New Plant”

Abstract

CSA N293 “Fire protection for CANDU nuclear power plants” has been extensively revised and was reissued in early 2007. N293-07 is planned to be the fire protection standard of reference for the next renewal of the various Canadian nuclear power station “Power Reactor Operating Licenses (PROLs)”. While the new design and installation requirements ( Clauses 6 and 7) are not retroactive to existing CANDU stations, there are many other changes to the standard that existing facilities are expected to comply with at the time of their next PROL renewal. All Canadian CANDU stations are encouraged to review N293-07 as soon as possible, and initiate the process and materiel changes required to comply with the new standard by their next station operating license renewal. This paper reflects one utilities initial efforts in this regard.
