Pickering Large Scale Fuel Channel Replacement Program

Abstract

The Pickering Nuclear Generating Station, located on the shore of Lake Ontario between Oshawa and Toronto has been in commercial service since 1971, The "A" station consists of four 500 MWe CANDU nuclear steam supply systems with associated electrical generation equipment. The CANDU pressure tube design allows simpler manufacturing requirements, on-power refuelling capability (thus increasing availability), simplified reactor control mechanisms and replacement of the pressure boundary in-core without a complete core disassembly. This paper provides an overview of a major project currently underway at the Pickering Nuclear Generating Station which is aimed at replacement of all of the pressure tubes in two of the reactors.
