> i) a concern about the disposal of nuclear wastes and the long-term cost of their storage

I don't understand this concern. If you already have several decades worth of nuclear waste to manage/dispose, is it really more expensive to manage/dispose another several decades? For example, if you're disposing in a deep geologic repository, is it really much more expensive to put a little bit of waste in a big hole versus a little more waste?

I don't think anyone is advocating 100% nuclear energy, but nuclear is the only clean base load energy source. Without nuclear, we're putting all of our eggs in the "renewable energy" basket (assuming the goal is to move off of fossil fuels) and praying for a miracle breakthrough for base load. Considering that it takes decades to bring a new nuclear plant online, decommissioning a nuclear plant is the height of folly. It necessarily means more dependence on fossil fuels and the countries who provide them (in Europe, this largely means Russia).
