Morphology

nuclear + submarine

The meaning is directly compositional: 'nuclear' (relating to atomic energy) modifies 'submarine' (an underwater vessel), so a B1 learner who knows both words can infer a submarine powered by nuclear energy. This modifier+noun pattern is common across languages and follows straightforward technical compounding, making the expression immediately understandable.

Etymology

The compound nuclear submarine is a literal name: nuclear points to the powerful energy source inside and submarine is a ship that goes under the sea. Because that energy lets the vessel stay 'underwater' for 'months', the name means a submarine 'powered by nuclear energy' that can remain submerged for a long time.
