Canada’s Candu Energy, a subsidiary of SNC-Lavalin, has been awarded three contracts with a combined value of CAD$34 million ($26 million) from Bruce Power for projects in support of the Major Component Replacement (MCR) programme.

SNC-Lavalin’s scope includes detailed designs for the unit 3&4 fuel channel and feeder replacement (FCFR), and a seismic margin assessment of the site.

“The three contracts are within SNCL Engineering Services, the cornerstone of our strategy moving forward to greater growth and support for our partner and customer,” SNC-Lavalin said.

The work comes in addition to that awarded under a Master Service Agreement signed in 2016. The services will extend the life of the Bruce reactors until 2064.

SNC-Lavalin will be responsible for the detailed design of the unit 3&4 MCR fuel channel assemblies and calandria tubes. This includes the pressure tubes, end fittings, positioning assemblies, bearing and shielding sleeves and inserts and rolled joints. It will also perform a stress analysis to determine the strains of the calandria and shield tank assembly.

SNC-Lavalin said the work has begun and is anticipated to be completed in 2023.

Under the second contract, detailed design of the unit 3&4 feeders will be undertaken, including a partial replacement of the feeder cabinet and items inside such as instrumentation lines and I&C components. This work has begun and continues into 2022, SNC-Lavalin said.

Finally, a seismic margin assessment will be undertaken to demonstrate the seismic adequacy of the station. This is scheduled to be carried out at Bruce unit 3 from January 2020 until May 2021, and unit 4 from June 2021 to February 2022.

 Mike Rencheck, President and CEO, Bruce Power said:  “As we progress our Life Extension programme, we continue to create jobs and boost our economy while ensuring a reliable supply of low-cost, clean electricity for Ontario families and businesses.”
