Description
A high-output nuclear reactor multiblock that consumes fissile fuel to generate extreme amounts of heat. At maximum size (18×18×18), the reactor supports multiple fuel assemblies with a burn rate of up to 1 mB/t per assembly, scaling total heat output linearly. The reactor produces heat only, requiring active cooling with water or sodium to prevent meltdown. When paired with a Thermoelectric Boiler and Industrial Turbine, it becomes one of Mekanism’s highest-throughput power systems.
