What it does

The mod is in an alpha build, and its reactors are not yet functional. The stated goal is full multiblock reactors built to realistic specifications, along with a radiation requirement that players must manage. Its author warns that the design could go badly wrong without care, so players should stay cautious around anything radioactive.

Key features

  1. Planned multiblock reactors

    Reactors are designed as multiblock structures based on realistic specifications, though the alpha build does not yet include working reactors.

    The planned reactor design includes a radiation requirement that players must handle to keep operations safe.
