A naval reactor is fundamentally a heat source for both propulsion and the ship's base electrical load. Steam turbines can transmit that energy through a direct-drive arrangement or generate electricity for propulsion motors. In the indirect arrangement, the reactor's heat first becomes electrical power before that power reaches the drive system. The distinction matters because nuclear-powered describes the energy source rather than one mandatory mechanical layout.

A reactor can drive machinery or generate electricity
The reactor supplies heat that can feed propulsion machinery directly or generate electricity before motors move the ship.
