Some reasons I'm skeptical it's a good idea in this particular case:

allow shareholder-owned utilities to charge customers for up to $20 million in nuclear research expenses

For one, they want me to pay for it as a utility customer with increased rates, and I'll have to pay for it even if it goes ridiculously over budget as large construction projects often do. Nuclear plants use a lot of water, bad things will happen if they don't get it, and Colorado is already having big climate-driven water problems and disputes over who has the rights to water usage. The effectiveness and affordability of solar is rapidly growing, so where's the analysis of whether nuclear will even still be a more cost efficient solution by the time a plant finishes construction, and why don't we build out solar and battery? Why can't we just do more of this? Nuclear plants rely on competent government oversight to avoid disasters, and while that's possible in theory the current state of things makes me worry about whether that will happen.
