Morphology

nuclear + fusion

The noun phrase is directly compositional: 'nuclear' (relating to atomic nuclei or atomic energy) combined with 'fusion' (the process of fusing) yields the process of atomic nuclei joining. This is a literal, technical combination following common scientific word-formation patterns and would be understandable to a B1 learner who knows both constituent words.

Etymology

Nuclear fusion comes from the simple image of tiny nuclear parts, the centers of atoms, joining together. Fusion means 'joining', and when those parts join they give off a lot of energy, which is why the process 'powers the sun' and could make clean power on Earth.
