Isotope Logistics
Isotope Logistics is a Mekanism addon for handling radioactive materials without turning your entire base into a hazard.
Create dedicated nuclear logistics networks with the Nuclear Entangloporter, safely move radioactive chemicals, package them into reusable containment capsules, phase-lock them for safe storage, and recover the original chemical whenever you need it again.
Active Radioisotope Capsules are dangerous by design. They can be processed, stored in dedicated radioactive bins, or kept in compatible AE2 and Refined Storage media. For ordinary storage and transport, phase-lock capsules to make them inert.
Features include:
- Dedicated Nuclear Entangloporter frequencies for items, energy, fluids, heat, and radioactive chemicals
- Radioactive Bins, Fluid Tanks, and Chemical Tanks in Mekanism tiers
- Radiological Encapsulation, Phase Control, and Chemical Reconstitution machines
- Reusable 1,000-unit Radioisotope Capsules
- Optional AE2 radioactive ME Storage Cells and Refined Storage Disks
- Isotope Neutralizers that instantly clear accumulated Mekanism radiation
- Full survival recipes, JEI support, and Mekanism-style progression
Mekanism is required. Applied Energistics 2 and Refined Storage integrations activate only when those mods are installed.
Isotope Logistics does not remove the danger from radioactive materials—it gives you the tools to handle them deliberately.
