Building NPPs in the west nowadays might be considered economically insane. If you consider nukes a viable alternative, calculate the (actual) cost and see what else might be done for that amount of money.
Don't get me wrong, I get the "let's go all nuke" argument. I just don't buy it. Right now, renewables are taken off the grid / switched off, because we can't store the power produced efficiently -- where I live, we chose to not produce / switch off renewable energy (and subsidy not producing it), instead of converting and storing it inefficiently. If we used the "all nuke" money for things like renewables and storage, it might still be "economically insane" FWIW (though I doubt that), but a lot less risky and, you might say, geeky.
