📋 Guided Progression (1.12.2 version) : 219 quests (Currently 140 are being worked on and are done, i just need to adjust the quests to avoid confusing intersections and then put the update here) across 5 ages (Metallurgical → Steam → Oil → Nuclear → Endgame)

What is NITRO?

You're looking at a nuclear technology progression pack for Minecraft 1.12.2 that deeply integrates HBM's Nuclear Tech with NuclearCraft: Overhauled. Over multiple years of development, NITRO has grown from a simple exploration pack into a challenging tech experience with over 30 custom CraftTweaker scripts, 18 custom multiblock machines, and thousands of modified recipes — all without needing GregTech.

The main intention of this pack is to experience the complete nuclear fuel cycle as realistically as Minecraft allows. You'll mine uranium, process it into yellowcake, enrich it through gas centrifugation, fabricate fuel rods, run fission reactors, and then reprocess your depleted fuel through a custom SILEX laser isotope separation machine. Every step matters, and every waste product needs to be handled.

If you enjoy technical modpacks that make you think about your processing chains, if you want nuclear technology that actually feels nuclear, this pack is for you.

***Nuclear Processing***

NITRO completely reimagines spent fuel reprocessing. The default NuclearCraft fuel reprocessor has been replaced with SILEX — a custom multiblock machine that uses laser crystals to separate isotopes from your depleted fuel. Depending on your fuel type, you'll recover uranium, plutonium, americium, curium, berkelium, or californium isotopes, along with highly toxic radioactive waste products like Strontium-90, Cesium-137, and Europium-155.

The Gas Centrifuge handles uranium hexafluoride enrichment, taking low-enriched material and producing weapons-grade isotopes. Steam Condensers in three tiers let you recycle exhaust steam back into water, creating sustainable power loops. The Decay Pool processes radioactive materials while outputting preheated water for steam generation.

With QMD, you can push even further — creating entirely new elements through Muon-catalyzed Fusion in the Nucleosynthesis Chamber.

***Mod Integration***

HBM and NuclearCraft weren't designed to work together, but NITRO bridges them seamlessly. You'll craft NuclearCraft machines using HBM's anvil and crucible. Solenoids and copper coils are interchangeable. Motors are shared between both mods. Basic plating requires crucible-cast steel from HBM before you can progress into NC's machine line.

This integration extends everywhere. Pam's HarvestCraft items feed into HBM's biomass production. Trinity handles radiation effects and fallout zones. Custom RadAway variants, iodine pills, and hazmat suits keep you alive when things get hot. Applied Energistics 2 helps you manage the complexity once your base grows beyond manual automation.

***Exploration & Space***

The world generation in NITRO uses Biomes O' Plenty, Better Caves, Better Nether, and The Beneath to create diverse environments worth exploring. Later on, Advanced Rocketry opens up space travel. Build rockets, establish orbital stations, and visit other planets to gather resources unavailable on the overworld.

Dilithium powers your most advanced propulsion systems. Space isn't just endgame content — it's where you'll find materials needed for the highest tier machinery.

***Progression & Quests***

NITRO comes with a BetterQuesting questbook that guides you through the progression. You won't be stumbling around trying to figure out what to do next. The quests explain the technology, point you toward the right machines, and reward you for hitting milestones.

The early game focuses on survival and getting your first HBM infrastructure running. Mid-game transitions into NuclearCraft fission and basic isotope processing. Late-game opens up MSRs, QMD particle physics, and Advanced Rocketry space exploration.

***Is this pack for me?***

Do you enjoy designing complex processing chains? Does the idea of managing radioactive isotopes and their decay products sound interesting rather than tedious? Does building a nuclear empire that spans from underground enrichment facilities to orbital stations appeal to you?

If you want something that feels more grounded in nuclear physics than typical tech packs — where every isotope has a purpose and waste is a real concern — NITRO will keep you engaged for hundreds of hours.
