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.

⚡ 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
