Following World War II, scientists and engineers in Canada turned their minds to the development of nuclear power for peaceful purposes.
Under C.D. Howe, the National Research Council laboratories at Chalk River became part of a new company called Atomic Energy of Canada Ltd., and development of a Canadian nuclear reactor for generating electricity began in earnest.
However, unlike the United States, the Soviet Union or Great Britain, Canada was a country of modest industrial capability. Reactors in these other countries were based on the Westinghouse nuclear submarine reactor design of the early 1950s.
When scaled up for power production, they required large stainless steel pressure vessels that we could not build in Canada. These reactors also used enriched uranium and in Canada we did not have enrichment capability.
