Morphology

nuclear + rocket

The meaning is directly and compositional: 'nuclear' (powered by or relating to atomic energy) modifies 'rocket' (a vehicle propelled for space/military use), so a B1 learner who knows both words can infer a rocket using nuclear energy. This adj+noun pattern is cross-linguistically common and does not require specialized knowledge to grasp the basic concept, so it is transparently understandable.

Etymology

Nuclear rocket comes from a clear image: a nuclear reactor is used as the engine to heat gas inside a rocket, so the hot gas shoots out and pushes the craft. That's why it means a rocket whose engine uses nuclear heat to push it into space.
