Whether subsidies are a good idea or not in general for nuclear is an interesting question. The article states that the current plan is to give production tax credits - tax credits for energy produced. Such a subsidy, which does not help mitigate the up front capital costs, would therefore not really address the root problem in the US. To the more general question though: subsidies are to incentivize people (or companies) to do a thing (or do more of a thing). In the case of nuclear power, the timelines involved in building a power plant are so long, and given the uncertainty of having the same tax credits staying in place for long enough to impact financial plans, it seems unlikely that it would actually have the effect we'd want on nuclear power production.
