Isn’t he using it in the same sense as ‘man-years’, a reactor-years? 500 reactor-years could be reached with no less than 20 reactors (500 / (1979-1954) = 20 reactors, if starting up in 1954, but of course the later reactors start, the more there needs to be to catch up).
Wikipedia claims that there were ~250 active nuclear reactors globally in 1979.
The chart makes it look like around 1000-1500 reactor-years of operation had occurred- possibly Jonah’s source was referring solely to power in the US, or perhaps an ‘active reactor’ is different from an ‘operating reactor’.
