A lot of comments I see are assuming that the worst, least trustworthy shippers are going to be using these irresponsibly. Presumably we won't just be handing out nuclear engines. There would have to be a pretty robust regulatory regime that manages the whole lifecycle, and whatever random ship is not going to qualify for a nuclear fit-up. The required regulation may render the whole thing infeasible, I don't know, but any realistic solution will be heavily regulated making most concerns about misuse unrealistic.
