Uranium was cheap from the 1960 until now, bar ~3 years around 2007 (a 'Bubble'), however research towards ways to not depend on it (mostly towards breeder reactors) was very intense in many nations from the 1950's to 2000, because of an economic perspective (there is no clear reason for uranium prices to stay low, especially after a nuclear 'Renaissance' and given that it is tied to ore grade, which gets lower and lower), a social perspective (breeders and such reduce the amount of nuclear waste and risk associated to it), and for some nations also a strategic perspective (all existing uranium sellers live under a superpower).
