Reactor Core Entrance (or Reactor Access in the Tallon Overworld) is a room in Metroid Prime on the Frigate Orpheon. It contains two Auto Defense Turrets that are easily dispatched with Missiles or charged shots, and a panel can be scanned to activate a Morph Ball hologram on the floor, which is used as in the previous room to open the next door. To the left, another door leads to a Save Station. The corpses of Space Pirates can be found lying around the room.
