Most theories point to Russia lobbying for Austria to stay hooked onto its gas exports, so they had to run a FUD propaganda campaign against nuclear before the referendum.
Especially that Austria isn't big on holding referendums to ask the population what it wants, like Switzerland does, and a few former Austrian ministers have worked or still do for Russian oil & gas companies.
But yes, pretty stupid.
Wasting a highly expensive taxpayer funded energy project as a political weapon just to spite the opposition party is peak politics.

*note, this is not anti nuc power, its all about how corruption, politics and really bad engineering have screwed the project from the beginning
Plus, that plant is not designed to create weapons grade nuclear weapons.
what he said was "Former Marcos Deputies have alleged that it was also intended to facilitate nuclear weapon design"
Also, its not like The Marcos regime was a stickler for the rules mate....
