Morphology

thermal + reactor

The constituents 'thermal' (related to heat) and 'reactor' (a device producing power) allow a learner to infer a reactor associated with heat or operating at particular temperatures, so there is some straightforward compositional clue. However, the precise technical sense—referring to neutrons slowed to thermal speeds by a moderator in nuclear physics—is specialized and not predictable from everyday meanings, so a B1 learner would not reliably derive the full meaning without prior exposure.

Etymology

The term thermal reactor comes from the idea that thermal means neutrons are slowed until they move like warm particles and the reactor is the machine where those slow neutrons keep the nuclear reaction going. So, thermal reactor means 'a reactor kept going by neutrons slowed to thermal or heat-like speeds'.
