Nuclear energy has a very high energy density output, per square footage of the nuclear facility. The highest of all energy generation. But, the cost appears to be very high. The nuclear reactor, is a very complex system of pipes and pumps, switches and relays, backup systems of backup systems, etc. It’s an incredibly complex way to produce electricity. It moves around a lot of radioactive water, in its pipes. And then, it has a nasty waste byproduct, which will take 10,000 years to degrade before it becomes relatively safe. This is longer than recorded human civilization. And far longer than any continuous government has existed. And the container holding the waste might actually deteriorate before the waste becomes safe. Thus, the nuclear waste might end up leaking into the ground water, and now poisoning your water supply. Whereas hydro is relatively safe. You’re just using gravity to spin the generator. Funnel the water rolling down a mountain, and let gravity do its thing. Easy. And no radioactive mess to deal with afterwards. You can even float some solar panels on top of your dam reservoir, to generate more energy. The dam will require maintenance of course. You have to clear the silt every few years. And then, you have to upgrade the concrete once every century or so. But, this is probably far easier, than dealing with radioactive waste.
