The Globe and Mail reports in its Tuesday edition that Candu (Canadian Deuterium Uranium) stands as one of Canada's most important technological innovations. Guest columnists Jean Chrétien and Mike Harris, co-chairs of Canadians for Candu, write that six decades after it was conceived, Candu remains the only nuclear power technology on the market that is both Canadian-made and Canadian-owned. The advent of Canadian nuclear power provided for clean, reliable and abundant energy at a time when the country's industrial base was growing rapidly. While the circumstances that brought Mr. Kowarski to Canada may have been unplanned, the subsequent and very successful deployment of Candu nuclear reactors at home, and later abroad, was the result of a concerted effort by government -- one that Mr. Chrétien and Mr. Harris believe must be replicated today to meet the urgent need for secure, reliable, emission-free electricity. In terms of addressing climate change, nuclear technology can play a pivotal role in decarbonizing energy grids across the globe, as Canada and its international partners drive toward net-zero emissions. (Canadians for Candu is a campaign by AtkinsRéalis to promote Candu nuclear-reactor technology globally.)
