a nuclear plant would not be used in any they are rather large and not suited for space...much less launch a plant is a rather large complex of reactors and support equipment that covers a rather large area and going into the thousands, at a conservative guess tons.
yes i know, the power required is electric but for the ship to travel to lets say Mars in 2 or less months, it will require Megawatts + of power which today only nuclear reactors can, even the CEO of Ad astra behind the company behind the Vasimr engine says so, unless the e-cat fusion/fission reactor story is not fake then that will change things.

Also the Russians have already made a space nuclear reactor decades ago so it is possible. NASA has made one and tested it on an ion engine years ago too.
