Stephen Harper would seem an unlikely pitchman for nuclear power. When the Prime Minister launches into his familiar spiel about Canada as an emerging "energy superpower," we all think we know what he's talking about - he's an Alberta MP, after all, and his father worked for Imperial Oil. Yet in a key speech last summer in London, his most gleeful boast was not about record oil profits, but about soaring uranium prices. "There aren't many hotter commodities, so to speak, in the resource markets these days," Harper joked to the Canada-U.K. Chamber of Commerce crowd. Then, noting that Britain is among those countries poised to begin buying new reactors for the first time in decades, he added: "We'll hope you remember that Canada is not just a source of uranium; we also manufacture state-of-the-art CANDU reactor technology, and we're world leaders in safe management of fuel waste."
