Given the regulatory delays and uncertainty of somewhat safer things like approval for orbital launches from Starbase, I imagine that SpaceX would not be all too eager to experiment with NTR given the regulatory environment for anything nuclear and that they want to get Starship flying humans within this decade. The regulatory environment is bad enough that I still expect this to eventually get cancelled again, only to be taken seriously when eventually another country is close to catching up technologically.
