Morphology

chain + reactor

The combination of 'chain' (a series of linked events) and 'reactor' (a device producing power) readily suggests a reactor that operates by a chain reaction, so a learner who knows both words can infer the general idea. However, the precise technical sense—a controlled nuclear fission chain reaction—and the specialized usage are domain-specific rather than everyday composition, so the meaning is not fully predictable without some subject knowledge.

Etymology

Chain reactor is named after the idea of a 'chain reaction' — one atom breaking sends out tiny pieces that make other atoms break, like a line of falling dominoes. So the machine called a reactor keeps this chain going to make 'energy'.
