Silo One’s reactor facility powers the servers and is the target of Donald’s bomb.
The power plant is located on level sixty-eight. An earlier description places the reactor across two levels beneath Mechanical and the general storerooms; the latest view describes reactors spanning three levels behind large doors.
Donald Keene says the reactor supplies power to the servers. He takes the bomb to the entrance of the main reactor room.
Large doors stand before reactors described most recently as spanning three levels.
The reactor facility provides power to the servers and is the destination of Donald’s bomb.
