The project is the centrepiece of the Major Component Replacement (MCR) program which will see the replacement of the main components of the reactor. Unit 6 is the first of six reactors being replaced by Bruce Power through the MCR program. This joint venture team (Aecon, AtkinsRéalis and United Engineers & Constructors) – operating under the banner Shoreline Power Group – will focus on the removal and replacement of calandria tubes, 480 pressure tubes, and 960 feeder tubes – the type of nuclear work that Aecon has specialized in for the better part of a decade. The rest of the scope of work includes construction management and trade labour.
