This mod allows the nuclear furnace from Alex's Caves to power Create boilers while it is smelting items. A nuclear furnace is about 2.5x to 4x more powerful than a superheated blaze burner, and can power up to 4 boilers at a time. The mod also adds a single item, Soul Goop, which can be smelted and unsmelted repeatedly. Through the eternal torment of the Goop, you can use a nuclear furnace as a dedicated reactor, without needing a constant stream of new items to smelt.
Obviously, this mod requires Create and Alex's Caves
