Bruce Nuclear Generating Station

There are eight CANDU units at the Bruce Power site on the shores of Lake Huron in Tiverton, Ontario, making it one of the largest nuclear power facilities in the world.

Unit 1 was laid up on 1997 and Unit 2 in 1995. In 2006, life extension projects started on these two units. Both units returned to the grid in 2012 to deliver safe and reliable power to the citizens of Ontario for the next 25 to 30 years.

Bruce Nuclear Generating Station Units 1 & 2 Restart

The refurbishment and restart of the Bruce Power nuclear generating station units by SNC‑Lavalin’s experts contributed significantly to the reduction of smog days in Ontario. 

Ontario’s Bruce Power nuclear generating station produces approximately 30% of Ontario’s energy needs through its CANDU® nuclear reactors. The refurbishment and restart of the station’s Units 1 & 2 contributed significantly to the reduction of smog days in Ontario from 48 in 2005 to 0 in 2014.

Our nuclear experts were part of that accomplishment, through a joint venture that was retained by Bruce Power to provide engineering, procurement and construction (EPC) services for the balance-of-plant portion of the refurbishment. The JV’s scope of work included items such as the refurbishment of the feedwater heaters, replacement of the main condensers, replacement and refurbishment of many major valves, refurbishment and commissioning of the moderator and primary heat transport systems’ D2O upgraders, replacement of the control distribution frame terminal blocks and overhaul of pumps and motors.

We also made CANDU history during this refurbishment project by completing a first-of-its-kind steam generator replacement. This was achieved in a building not designed for replacements and marked the beginning of a program to extend the life of the CANDU reactor fleet. A total of 1.4 million person hours were worked during steam generator replacement with no lost time injuries. The Bruce Restart project was completed in 2012.
