One of the reasons for the demise of nuclear physics may well have been that very few new discoveries were made that were of immediate practical use in the reactor physics program. Instead, what emerged was a severe critique based on ”Pandemonium”. Many people employed on the practical or engineering side held doctorates in nuclear physics that lay outside the scope of AECL at that time. I suspect that many of them were not flexible enough to fit in with the advanced nuclear physics research concepts pioneered by people like Doug Milton, John Hardy, Otto Hausser, David Ward, Gordon Ball and Tom Alexander. They then turned to making money and reactors. Research that had no monetary benefit for the reactor program was deemed useless and opposed by many ex-nuclear physicists. Better to reign in hell than serve in heaven.
