Nuclear along with other energy sources are in a flux until policies are fleshed out. Nuclear is one he mentions but drill baby drill is a popular chant.

Funding for green energy going away hurts nuclear but that does not rule out separate new funding. Trying to keep this more fact based than political. The future of nuclear is entering a new phase hopefully more pro-nuclear.
