About this game

The nuclear idle tycoon simulator is back — and it's free.

Build your own power company from the ground up. Manage heat, optimize production, and grow a massive energy empire. In Reactor 2, you don't just construct power plants — you power an entire evolving city.

Master the system, discover your best strategy, and scale your profits to become a true industrial billionaire.

⚡ BUILD, POWER, AND EXPAND
Start small with basic wind turbines and grow into a high-efficiency nuclear power network.
Your mission is simple — supply energy to the city. Your challenge? Control the heat.
• Produce heat with diverse power sources
• Convert heat into electricity for the city
• Cool your systems to avoid production shutdowns
Balance everything perfectly to achieve maximum efficiency.

😌 RELAXED STRATEGY, NO PUNISHMENT
Reactor 2 is an idle clicker game built for thinkers, not masochists.
Your reactors never explode or reset your progress — they simply pause and cool down. This creates a no-loss, strategy-first experience where you experiment, optimize, and build at your own pace.

• Renewables: Solar, Wind, Hydro, Tidal
