Chris Keefer is a Toronto-based medical doctor and president of Canadians for Nuclear Energy. In his fourth appearance on the podcast, (previous appearances were November 2021, May 2021 ) and April 29, 2022) Keefer talks about Ontario Power Generation’s decision to reverse course and extend the life of the Pickering Nuclear Generation Station, a move that could keep the 3.1-gigawatt plant running for another 30 years, the essentiality of the Cobalt 60 isotopes that are produced by CANDU reactors, and why Ontario has “the most pro-nuclear government in the western world.” (Recorded September 30, 2022.)
