About

Take control of a nuclear reactor and keep it running. Pull the control rods, balance coolant and turbine output, and meet the city's power demand before the heat gets out of hand. ⚛️ Start up the reactor and push it to full power 🌡️ Watch temperature and pressure, and hit SCRAM when things go wrong ⚡ Complete power contracts and hold your output steady to earn credits 🔧 Upgrade coolant pumps, turbines and containment to run hotter and safer ⚠️ Handle pump faults, peak demand and cold fronts as they come Run a clean, stable plant or see how close you can get to meltdown.
