About this Mod

Mekanism Fission Meltdown Rework

A small addon that enhances the meltdown mechanics of the Mekanism Fission Reactor.

Instead of a simple explosion, meltdowns now create a large-scale catastrophic event that leaves visible destruction across the landscape.

Small Note: This mod can be put on your server and server only so your clients do not need to install it

Features

  • Massive radial destruction pattern when a reactor melts down
  • Terrain is blasted outward in dramatic spokes
  • Far larger environmental impact than vanilla Mekanism meltdowns
  • Creates memorable "nuclear disaster" moments on servers
  • Designed to look spectacular from above or in replays

What Happens During a Meltdown

When a fission reactor reaches meltdown conditions:

  1. The core collapses.
  2. A massive explosion erupts from the reactor center.
  3. Destructive shockwaves carve radial blast paths through the terrain.
  4. Fire spreads across the surrounding area.

The result is a huge crater-like disaster zone that clearly shows the power of a reactor failure.

Compatibility

  • Requires Mekanism and Mekanism Generators
  • Intended for modded survival servers and tech modpacks

Use Cases

This addon is perfect for:

  • Tech modpacks
  • SMP servers
  • Hardcore engineering gameplay
  • Players who want reactor failures to feel dangerous and cinematic

Disclaimer

This mod intentionally makes meltdowns significantly more destructive.
Build your reactors responsibly.
