The Nether Reactor


Generated Structure



First Appearance

Version 0.5.0


Update 0.12.1

The Nether Reactor, sometimes known as the Nether Machine, was a player-built structure that was added in Update 0.5.0. When activated, the Reactor spawned many blocks and items and a tower of Netherrack around it. It was removed in Update 0.12.1.


To create the Nether Reactor, the Nether Reactor Core was needed, which consisted of Diamonds and Iron Ingots, 4 Gold Blocks and 14 Cobblestone were needed.


  • The Reactor remained active for about 45 seconds.  
  • When the Reactor is active, a Netherrack spire would spawn. After deactivation, some Netherrack blocks would disappear, causing there to be holes in the spire.
  • The Gold and Cobblestone blocks would turn into Glowing Obsidian, then after deactivation, would turn to regular Obsidian.
  • The tower would spawn Zombie Pigmen if playing on normal. They spawned in groups of 2-3. Unlike PC and Console edition, they were naturally hostile.
    • This changed when they added the Nether.
  • When activated there were 3 stages of the Nether Core Reactor, no matter what when mined it would produce the original Reactor.
  • When in multiplayer, all players would have to stand next to the Reactor to activate it.

Items Spawned 


  • Before 0.11.0, mining away the Nether Reactor Core during activation would cause eternal night. Even if the player sleeps in a bed, the player will only see one minute of daylight before it returns to night.
  • When the player activated the Nether Reactor, the Gold and Cobblestone blocks would turn to Glowing Obsidian. The Core can also be easily mistaken for turning into Glowing Obsidian.
  • After 0.11.0, the Reactor cannot be created on Bedrock level.
  • Before 0.6.0, the tower it generated was of Obsidian.
  • The Reactor did not work in Creative Mode.
    • However, the Reactor could continue to work in Creative Mode in Update 0.11.0 after activation in Survival Mode.
  • The Nether Reactor was removed in Update 0.12.1. However, the blocks still exist in game files.
    • The developers have stated it may gain another use in the future.
  • Before Update 0.12.1, a Nether Reactor was the only way to gather Netherrack.
  • When the Reactor is drained, it will turn to night.
