First Appearance

Version 0.5.0

The Nether Reactor Core is a Pocket Edition exclusive block used in the Nether Reactor. It is very expensive to build, so it is very rare to be able to make one.



Once activated by being surrounded by the proper amount of cobblestone and gold blocks, the player can activate the reactor by clicking on it. It temporarily transforms into Glowing Obsidian.

The Nether Reactor Core will be removed from Survival and will only be in the Creative inventory for decorational purposes after Update 0.12.1, as the Nether will be added.


  • Making more than 1 is a waste because the core can be used more than once.
  • It can be used as a decoration After the 0.12.1 Update.
  • Hitting the block when it is not placed in the correct Nether Reactor pattern will make a client message saying 'Not the correct pattern!'
  • On multiplayer, if a player activates the Reactor when other players are out of range, it will say 'All players need to be close to the Reactor'. This is probably because of the way it skips day into night.
  • It has 3 stages: before activation, activation, and burnt out.
  • The tower it generates was made of obsidian before Update 0.6.0.
