Ontario awards 14 supply contracts for the G7's first small modular reactor at Darlington

Stephen Lecce, Ontario's energy and mines minister, unveiled the awards at a Scarborough news conference. Armstrong Fluid Technology, based in Scarborough, has a C$3.9 million contract for a pumphouse enclosure and pumps. Hooper Welding of Oakville makes steel for the structural modules, and Toronto's St. Mary's Cement provides concrete and operates an on-site batch plant for high-density mixes, the province said. Celeros Flow Technology will build the reactor's control rod drive pump at its nuclear plant in Burlington, the Clarington Post reported. Armstrong's was the only contract value in the announcement.

Ontario Power Generation is putting up the reactors, formally the Darlington New Nuclear Project, on the site of its Darlington station in Clarington, Durham Region. Four reactors are planned. The first, already under construction, should cost about C$7.7 billion including shared infrastructure and start producing power by the end of 2030; all four are estimated at C$20.9 billion, Frequency News reported. Together the units would deliver 1,200 megawatts, which the province says is enough for about 1.2 million homes.

Ottawa has committed up to C$2 billion through the Canada Growth Fund and Ontario up to C$1 billion through the Building Ontario Fund. Seven Williams Treaties First Nations have announced a C$700 million investment. The province says Ontario companies will get 80% of the project's spending and that more than 100 Canadian firms have already signed agreements with OPG.
