The Nether Reactor Core was a Pocket Edition exclusive Block used in the Nether Reactor.

Nether Reactor texture prior to 0.15.0



The Nether Reactor Core was a component of a Player-made structure that activated a Nether Spire. When the wrong structure was created, a message would broadcast saying, "Incorrect Pattern." When the correct structure was created and all Players in Multiplayer mode were near the Reactor, a message would broadcast saying, "Active."


Once activated by being surrounded by the proper amount of Cobblestone and Gold Blocks, the Player could activate the reactor by tapping it. It temporarily transformed into Glowing Obsidian.

The Nether Reactor Core was removed from Survival and Creative Mode in Update 0.12.1.


  • It had 3 stages: before activation, activation, and burnt-out.
  • The tower it generated was made of Obsidian before Update 0.6.0.
  • After Update 0.12.1, a placed Nether Reactor will not be removed, but when mined, it will drop 3 Diamonds and 3 Iron Ingots.
  • It can still be obtained by mining one with a Silk Touch Enchanted Tool.
  • Through modifications, the Nether Reactor Core can be placed and can function like it did before Update 0.12.1.
  • Bug: The texture was changed in Update 0.15.0 due to a bug where the texture was switched with the Plastic Texture Pack.
