I don't think that nuclear energy is cheap because waste disposal is very expensive.
I mean as per the rate quoted in the article. It seems pretty cheap which means the operational costs could also be cheap but anyways i really don't know much about what it takes to set up a nuclear plant.
Maybe they are just given discounted tariffs as per an agreement.
But hydropower looks more attractive.
Probably not in most countries, including mine. Even the industrial tariffs are just unbearable
