I read that article before you posted it, I don't think it's a subsidy because so many other businesses don't even have to pay a premium like that but can be even more dangerous. Look at all the gas explosion stuff going on in California. Do gas companies have to pay a huge insurance premium like nuclear? I don't know but probably not. I think commercial natural gas has killed more people than commercial nuclear in the U.S. Another unfair levy aimed at nuclear power actually, not a subsidy. In reality on the surface it looks like other forms of power are less safe than nuclear power and could probably use more insurance than nuclear.
Look at the banking industry. They didn't even have to pay insurance like a nuke plant does but I wonder how many lives the big banks destroyed back in 08? And who bailed them out? Our government. Nuclear power has been pouring money into those insurance premiums and from "help" from INPO etc and I doubt the got that kind of a return..
