Live systems to manage
Nucleares
Take control. Prevent disaster. Power the world.
A deep nuclear reactor simulator where you operate a full power plant, balance energy output, and stay calm when systems fail.
ScrollPlant overview
Every system answers to you
Nucleares puts you in charge of a complex facility: more than two hundred live parameters, one hundred fifty switches, and a reactor core built for serious operators.
Hands-on plant controls
Enhanced reactor core
Precision reactivity control
Mechanics
Master the plant under pressure
From ignition protocols to chemistry and prestige upgrades, every decision can keep the grid alive—or push the core past its limits.
Realistic Reactor Operation
Command every major plant system—from the control room to containment, turbines, and cooling towers.
- Monitor and adjust reactor power, coolant flow, and steam generation in real time.
- Respond to equipment failures, floods, and fires under pressure.
- Balance thermal output without simplified shortcuts.
AI Operational Assistant
Work with AO, your AI companion for ignition protocols, alarms, and crisis management.
- Upgrade AO skills to unlock advanced plant assistance.
- Run remote tasks from your operator tablet anywhere in the facility.
- Coordinate fuel loading, control rods, and maintenance workflows.
Advanced Core & Chemistry
Operate a nine-block core with seventy-two control rods, plus deep chemistry systems.
- Fine-tune reactivity with boric acid dosing and filtration.
- Manage ion exchange columns and coolant pH to prevent corrosion.
- Account for xenon-135 and iodine-135 dynamics that reshape stability.
Objectives & Prestige
Meet daily energy goals, earn Prestige, and expand what your plant can handle.
- Balance fuel use, maintenance costs, and rising community demand.
- Spend Prestige on upgrades, fuel blocks, protective gear, and waste cleanup.
- Level up into harder scenarios as your operator expertise grows.
No Hand-Holding
